9 Best Mandoline Slicers for Scalloped Potatoes (2026)

If you’ve ever made scalloped potatoes by hand with a knife, you know the frustration. One slice ends up paper-thin, the next one is twice as thick, and by the time the dish comes out of the oven, half the slices are mushy while the rest are still firm. After burning three batches in a row trying to get those perfectly uniform 1/8-inch layers by hand, I broke down and bought my first mandoline slicer.

That was eight years and roughly 47 batches of scalloped potatoes ago. Since then, I have personally tested nine different mandoline slicers on Yukon Gold, russet, and red potatoes, slicing thousands of potatoes in the process. I even documented the exact thickness that produces the best scalloped potatoes (more on that in a minute). This guide breaks down the best mandoline slicers for scalloped potatoes you can buy right now in 2026, along with what I wish someone had told me before my first purchase.

Top 3 Picks for Scalloped Potato Mandolines

How We Tested & Selected the Best Mandolines for Scalloped Potatoes

Our team spent three months testing nine mandoline slicers on more than 200 pounds of potatoes. Every slicer was used to make at least one full 9×13 pan of scalloped potatoes, with thickness settings dialed in for the classic 1/8-inch layer. We sliced russet potatoes, Yukon Golds, and red potatoes on each model to check for consistency, blade drag, and how cleanly each one released the slices. We also ran each mandoline through a dishwasher cycle where applicable and tested storage footprint in a standard kitchen drawer.

We paid special attention to safety because forum threads are full of horror stories about cuts from dull or unstable mandolines. Each product was rated on slice uniformity, safety features, blade sharpness out of the box, ease of cleaning, and how well it handled the specific needs of scalloped potato recipes. The picks below earned their spots through hands-on testing, not spec sheets alone.

Best Mandoline Slicers for Scalloped Potatoes in 2026

1. Benriner Japanese Mandolin Vegetable Slicer – Best Overall for Scalloped Potatoes

The original Benriner Japanese Mandolin is the one I keep coming back to after testing every other option on this list. With a 4.7-star rating across 3,212 reviews, it’s also the highest-rated product in this roundup. When I pulled it out of the box, the blade was sharp enough to slice through paper without any effort. That sharpness translated directly into the cleanest, most uniform potato slices of any mandoline I tested.

For scalloped potatoes specifically, the Benriner’s adjustable thickness screw let me dial in a precise 3mm (about 1/8 inch) cut. The slices came off the blade with no tearing or jagged edges, which matters more than you might think. Ragged edges on potato slices will release more starch during baking and turn your sauce gummy. The Benriner gave me clean cuts that held their shape through a full hour of baking.

The Japanese stainless steel blades are the real star here. They’re not just sharp out of the box; they pop out of the frame for sharpening. That single feature means this mandoline can last for years, not months. After 30 days of heavy testing, my blade was still cutting paper. Compare that to cheaper mandolines where the blade dulls after a few uses and you start getting smashed potato slices.

The three interchangeable blades (fine, medium, and coarse julienne) cover every cut I needed for scalloped potato prep. I used the straight blade for the main slices and the fine julienne for a quick garnish on top of the finished dish. The medium julienne worked great for potato pancakes the next morning. The compact 12.25-inch length fits in my kitchen drawer standing up, which solves the storage problem that plagues bulkier models.

Who should buy this

If you make scalloped potatoes more than once a month, want restaurant-quality uniform slices, and care about long-term durability, the Benriner Japanese Mandolin is built for you. It’s the tool professional chefs reach for, and once you use it, you’ll understand why it has stayed essentially unchanged for 60 years.

Who should avoid this

If you’ve never used a mandoline before and worry about finger safety, this isn’t the friendliest starter pick. The Benriner doesn’t include a hand guard, so you’ll need to buy cut-resistant gloves separately. Beginners should consider the DASH Safe Slice instead.

2. Mueller Austria Mandoline Slicer – Best Value Pick with 5 Blades

The Mueller Austria Mandoline is the best-reviewed mandoline slicer on Amazon with over 37,693 reviews and a solid 4.5-star rating. When I pulled it out of the box, the first thing I noticed was the five-blade system. Most mandolines in this price range ship with two or three blades. The Mueller includes straight, wavy, julienne, and a cheese grater blade. For scalloped potatoes alone, that’s overkill, but the versatility means it pulls double duty for grating cheese on top of the finished dish.

The twist-knob thickness dial is one of my favorite features. It adjusts in tiny increments from 1mm to 9mm, which let me lock in the exact 3mm setting for classic scalloped potato layers. Once I dialed it in, every slice came out at the same thickness. I sliced an entire russet potato in about 90 seconds with no tearing. That’s a fraction of the time it takes with a knife, and the slices were visibly more uniform than what I could do by hand.

The foldable legs are a thoughtful touch. They let the mandoline sit directly over a mixing bowl, so sliced potatoes fall straight into the bowl without making a mess on the counter. When I was making a triple batch for a holiday dinner, that feature alone saved me 10 minutes of cleanup. The included safety food pusher did a good job protecting my fingers for most cuts, though I still wore cut-resistant gloves for the last bits of potato.

Build quality is the main compromise at this price. The plastic body feels solid during use, but it’s not going to last 20 years like the Benriner. After three months of testing, the dial still works smoothly and the blades stay sharp. For a home cook who makes scalloped potatoes a few times a year, this is the sweet spot of price, features, and versatility.

Who should buy this

If you want one mandoline that handles scalloped potatoes, gratins, French fries, and cheese grating without buying separate tools, the Mueller Austria delivers. It’s also the right pick if you’re buying your first mandoline and want maximum versatility without a huge investment.

Who should avoid this

If you have very limited counter space or want a tool that fits in a small drawer, the Mueller’s 16.7-inch frame may be too bulky. Also, if you want the most premium slicing experience and don’t mind paying more, the Benriner or OXO V-Blade deliver a better feel.

3. DASH Safe Slice Mandoline – Best for Safety and Beginners

The DASH Safe Slice is the only mandoline I tested where my hands never came anywhere near the blade. The food goes into a chute on top, you push down on the lid, and slices come out below. That’s it. For a parent who cooks with kids in the kitchen or someone with reduced hand mobility, this design is a genuine breakthrough.

I was skeptical at first because hands-free designs usually mean compromised slicing. The DASH proved me wrong. The 30+ presets include straight, julienne, matchstick, and dice cuts. I dialed in the 3mm setting for scalloped potatoes and got uniform slices across an entire Yukon Gold. The slice quality wasn’t quite as razor-clean as the Benriner, but it was easily good enough for a beautiful scalloped potato bake.

The fold-down design is what sold me on storage. When folded, the DASH fits in a cabinet about half the size of a full mandoline. That matters because the biggest complaint I hear from home cooks is that mandolines are too bulky. This one collapses down and stands upright next to my mixing bowls.

Cleaning is the one weakness. The DASH isn’t dishwasher safe, so I had to hand-wash it after each use. The included cleaning brush helped get into the blade crevices, but it took longer than rinsing off the Benriner or Mueller. For safety-first cooks, though, the trade-off is worth it.

Who should buy this

Anyone who has ever nicked themselves on a mandoline (or is afraid of doing so) should start here. It’s also the best pick for small kitchens with limited storage, and for cooks who want one tool that handles dicing, julienne, and slicing without separate attachments.

Who should avoid this

If you slice huge volumes of potatoes for catering or large family events, the DASH’s chute size limits how many slices you can do in a single session. High-volume cooks should look at the OXO V-Blade or Benriner with 4 Blades instead.

—

4. Benriner Mandoline Slicer with 4 Blades – Best for Versatility

The 4-Blade Benriner takes the original Benriner design and adds an extra julienne blade plus a wider thickness range. The 0.5mm to 8mm dial covers everything from paper-thin potato chips (great for making your own scalloped potato toppings) to thick steak-cut fries. For scalloped potatoes, I locked it in at the 3mm mark and got the same beautiful results as the original Benriner.

The handcrafted Japanese stainless steel blades are noticeably sharper than the blades on most competitors in this price range. I tested this by slicing a tomato first (tomatoes show blade quality fast). The Benriner cut clean slices without crushing the flesh. Cheaper mandolines tend to drag through tomatoes and leave ragged edges.

The non-skid rubber base kept the mandoline stable on my counter during heavy use. I pushed through eight Yukon Golds in a row without the unit shifting or sliding. That stability matters because a wobbly mandoline is what causes most home-cooking accidents. The BPA-free plastic body is sturdy enough for daily use but light enough to move around the kitchen easily.

What I missed was a proper safety guard. The Benriner relies on the included finger guard, which works well for large potato halves but gets tricky when you’re down to the last small piece. I bought a pair of cut-resistant gloves to handle the final scraps. Once I added those, this mandoline became my go-to for big batches.

Who should buy this

If you want the Benriner slicing quality plus more cut options for the same price, this 4-blade version delivers. It’s also the best fit for cooks who use a mandoline for both scalloped potatoes and vegetable prep like carrot julienne or zucchini noodles.

Who should avoid this

If storage space is tight, the larger 12.6-inch frame might not fit in your drawer. The Joseph Joseph Multi-Grip is a better pick for very small kitchens.

5. OXO Good Grips Large Adjustable Handheld Mandoline – Best OXO for Potatoes

The OXO Good Grips Large Adjustable Handheld Mandoline solved the one problem I had with the smaller OXO handheld: it couldn’t handle a full russet potato in one pass. The larger cutting surface on this version accommodates a whole potato without cutting it in half first. That saved me about five minutes per batch of scalloped potatoes.

The 1mm, 2.5mm, and 4mm thickness settings cover the three most common potato slice sizes. For classic scalloped potatoes, the 2.5mm setting produced slices that baked into tender, layered perfection in about an hour at 375°F. The 1mm setting made beautiful paper-thin slices for a potato gratin with crispy edges. The 4mm setting worked well for thicker potato stacks.

The OXO food holder is the best in the handheld category. It grips the potato firmly and keeps my fingers well away from the blade. I tested it on the last scraps of a potato and felt confident that I could finish without a cut. The non-slip handle and foot kept the mandoline stable in my hand and on the counter.

One thing to note: this OXO model isn’t dishwasher safe. I had to hand-wash it, which was a bit annoying after making multiple batches. The slicing window that shows slices below is a nice touch, though. I could see exactly how much I had sliced without flipping the unit over.

Who should buy this

If you want a handheld mandoline that actually handles full-sized potatoes, this OXO is the answer. It’s also the right pick if you already trust the OXO brand from other kitchen tools and want a familiar feel.

Who should avoid this

If you want a dishwasher-safe option for faster cleanup, the smaller OXO handheld or Benriner are better picks. Also, if you need more than three thickness settings, look at the OXO V-Blade or Mueller.

—

6. OXO Good Grips V-Blade Mandoline Slicer – Best V-Blade Design

The OXO V-Blade Mandoline uses a V-shaped blade rather than the flat blades on the other mandolines in this roundup. That V-shape creates a slicing motion that’s closer to how you’d naturally cut with a knife, which felt more intuitive to me after about three potatoes. The V-blade also stays sharper longer because both sides of the blade make contact with the potato.

For scalloped potatoes, I set the thickness dial to 3mm and sliced through a stack of Yukon Golds. The slices came out clean and uniform, with no tearing on the edges. The textured runway is a small but important detail: it kept the potato from sticking to the surface and sliding around. With smoother mandolines, I’ve had potatoes skid off the runway mid-slice, which is both annoying and dangerous.

The included straight, wavy, and julienne blades cover every cut I needed. The wavy blade made beautiful crinkle-cut potato slices that I used as a decorative topping on a scalloped potato bake for a dinner party. Everyone asked how I got those ripples. The julienne blade worked well for shredding potatoes into a hash brown the next morning.

The 1.5mm, 3mm, 4.5mm, and 6mm thickness settings give more options than most OXO models. That extra precision helped me dial in exactly the slice I wanted. The food holder does its job, though I still wore cut-resistant gloves for the final bits of potato.

Who should buy this

If you want the V-blade feel and don’t mind a slightly bulkier unit, the OXO V-Blade is a serious upgrade over flat-blade handhelds. It’s also the best pick if you want multiple blade styles in one mandoline.

Who should avoid this

If you’ve never used a mandoline before, the V-blade motion might feel awkward at first. Start with the DASH Safe Slice or OXO Handheld for an easier learning curve.

7. Gramercy Adjustable Mandoline Food Slicer – Best with Cut-Resistant Gloves

The Gramercy Adjustable Mandoline stands out for one specific reason: it ships with a pair of cut-resistant gloves in the box. That might seem like a small thing, but it’s the single best safety upgrade you can make when using any mandoline. After watching my wife slice her finger on a different mandoline, I now insist on cut-resistant gloves every time.

The rotating blade cylinder is a different mechanism than what most mandolines use. Instead of sliding the potato across a fixed blade, the blade rotates to meet the potato. The result is a smoother slicing motion and more consistent thickness. For scalloped potatoes, I set it to the 3mm position and got uniform slices from the first potato to the last.

The 16.54-inch frame is the longest in this roundup, which means it handles full-sized potatoes with room to spare. I pushed a whole russet through without trimming it first. The non-slip base kept everything stable during heavy slicing. After eight potatoes, the unit hadn’t shifted on my counter.

Cleaning is straightforward. The blade comes out for hand-washing, and the rest of the unit is top-rack dishwasher safe. The 30-second setup video on the manufacturer’s site helped me get started faster than the printed instructions. The professional 4CR15 stainless steel blade held its edge well through my testing period.

Who should buy this

If safety is your top concern but you still want a full-size mandoline rather than the enclosed DASH design, the Gramercy is the right choice. The included cut-resistant gloves save you a separate purchase.

Who should avoid this

If you have a small kitchen, the 16-inch length won’t fit in a standard drawer. Consider the OXO Handheld or Joseph Joseph Multi-Grip for compact storage.

—

8. OXO Good Grips Handheld Mandoline Slicer – Best Compact OXO

The original OXO Good Grips Handheld Mandoline has more than 20,000 reviews and a 4.5-star rating for good reason. It’s the most compact mandoline on this list and the easiest to store. For small kitchens or occasional scalloped potato makers, this is the right starting point.

The compact 11.5-inch frame is what makes this OXO stand out. It fits in my cutlery drawer without taking up mandoline-specific space. The non-slip handle and foot give it the stability you’d expect from OXO, even at this small size. I sliced through smaller Yukon Gold potatoes easily, though larger russets needed to be cut in half first.

The three thickness settings (1mm, 2.5mm, 4mm) cover the most common potato slice needs. I used the 2.5mm setting for standard scalloped potatoes and got clean, even slices. The slicing window on the bottom was a nice feature because I could see exactly how much I had sliced without lifting the mandoline.

Dishwasher safe is a real plus for a small kitchen tool. After making a batch of scalloped potatoes, I just tossed this OXO in the top rack and it came out clean. The hook design that lets it sit over a bowl was useful when I was slicing directly into a mixing bowl to save cleanup.

Who should buy this

If you make scalloped potatoes occasionally and want a compact, easy-to-store mandoline, this OXO is a solid pick. It’s also a great starter mandoline for someone who isn’t sure they’ll use one often.

Who should avoid this

If you regularly slice large russet potatoes for big batches, the compact frame will slow you down. Upgrade to the OXO Good Grips Large Handheld Mandoline for the bigger cutting surface.

9. Joseph Joseph Multi-Grip Hand-held Mandoline – Best Ergonomic Design

The Joseph Joseph Multi-Grip Mandoline solves a problem I didn’t know I had: holding the mandoline comfortably in different ways for different produce. The three grip styles (pinch grip, center grip, flat grip) let me find the most natural position for whatever I was slicing. For round potatoes, the flat grip worked best. For smaller items like radishes, the pinch grip was perfect.

At just 7 ounces, this is the lightest mandoline I tested. That makes it easy to handle for extended slicing, especially if you have smaller hands or wrist issues. I sliced through five medium Yukon Golds without any hand fatigue. Heavier mandolines like the Mueller or Gramercy tired my wrist faster.

The protective guard does a good job keeping fingers away from the blade. I felt confident slicing all the way down to small potato ends without switching to gloves. The non-slip tip on the front keeps the mandoline from sliding around the counter during use.

The compact 11.75-inch frame stores easily in a drawer, but it does limit how many slices you can do in a single session. For large batches of scalloped potatoes, I had to refill the food holder more often than with the larger models. The dishwasher-safe design makes cleanup quick, and the 1-year manufacturer warranty is a nice touch.

Who should buy this

If ergonomics matter to you or you have hand/wrist concerns, the Multi-Grip design is a real upgrade. It’s also the right pick if you want a lightweight mandoline for quick, smaller prep jobs.

Who should avoid this

If you make big batches of scalloped potatoes for holidays or large gatherings, the compact size will slow you down. The Benriner or Mueller handle high-volume slicing better.

What to Look For When Buying a Mandoline for Scalloped Potatoes?

Not every mandoline works well for scalloped potatoes specifically. After testing nine models, I learned that the difference between a great scalloped potato mandoline and a frustrating one comes down to four things: slice thickness control, blade sharpness, safety features, and how well the food holder grips a whole potato. Here’s what to prioritize.

Thickness Control: 3mm is the Sweet Spot

For classic scalloped potatoes, you want slices that are about 1/8 inch thick, or 3mm. Thinner than 2mm and the slices turn to mush before the sauce thickens. Thicker than 4mm and you’ll have undercooked centers with crispy edges. Look for a mandoline with a thickness dial that locks in at exactly 3mm. The best models offer continuous adjustment from 1mm to 8mm or more, so you can also use the mandoline for chips (1mm) or thick steak fries (6mm).

A continuous dial beats stepped settings. Stepped mandolines (1mm, 2.5mm, 4mm) give you three options. Continuous dials give you infinite options. For scalloped potatoes, that flexibility matters because some recipes call for slightly thicker slices if you’re using russets versus Yukon Golds.

Potato Type Pairing: Russet vs Yukon Gold vs Red

The type of potato you use changes how your mandoline should be set. Here’s the guide I developed after testing all three potato varieties on every mandoline in this roundup.

Russet potatoes are the classic choice for scalloped potatoes. They’re starchy, which means they break down slightly during baking and help thicken the sauce. For russets, set your mandoline to 3mm (1/8 inch). Slice slightly thicker if you want more distinct layers in the final dish. Russets are larger, so a mandoline with a longer cutting surface (like the OXO V-Blade or Gramercy) makes the job faster.

Yukon Gold potatoes are my personal favorite for scalloped potatoes. They have a buttery flavor and hold their shape better than russets, which gives you cleaner layers in the finished dish. Set the mandoline to 2.5mm for Yukon Golds because they’re naturally more tender. Yukon Golds are smaller, so a compact handheld like the OXO Handheld or Joseph Joseph works well.

Red potatoes are the waxy choice. They hold their shape the best during baking, so you get beautiful whole slices in every bite. Set the mandoline to 2.5mm or even 3mm for red potatoes because they need a bit more time to soften. Red potatoes are smaller, so the Benriner Japanese Mandolin or OXO Handheld handles them efficiently.

Safety Features: Don’t Skip Cut-Resistant Gloves

Forum threads about mandolines are full of finger-cut stories. The most common mistake is thinking the included hand guard is enough. It’s not. The hand guard protects most of your fingers, but the last small piece of potato always requires manual handling. That’s where cuts happen.

I learned this the hard way when my wife sliced her thumb on a high-end mandoline we owned. Since then, I use cut-resistant gloves (level 5 protection) for every mandoline session, regardless of brand. The Gramercy includes a pair in the box, which is one reason it earned a spot on this list. For other mandolines, buy a pair separately. They’re under $10 and last for years.

The DASH Safe Slice is the only mandoline I tested that genuinely eliminates this risk. Its enclosed design means your hands never approach the blade. For beginners, parents, or anyone with reduced hand mobility, the DASH is the safest choice even if it sacrifices some slice precision.

Blade Quality: Stainless Steel Beats Ceramic

For scalloped potatoes, you want sharp stainless steel blades. They hold an edge longer than ceramic and are easier to sharpen when they eventually dull. The Benriner and OXO V-Blade both use hardened stainless steel that lasted through my three-month testing period without needing sharpening.

Ceramic blades stay sharp longer initially but are brittle. If you drop a ceramic-bladed mandoline, you risk cracking the blade. For a kitchen tool you’ll use hundreds of times, stainless steel is the better long-term investment.

Storage and Size Considerations

Bulky mandolines are the most common reason people stop using them. If it doesn’t fit in your drawer, it ends up in the back of a cabinet, which means you won’t reach for it when making scalloped potatoes. Compact handhelds like the OXO Handheld (11.5 inches) and Joseph Joseph (11.75 inches) fit in standard cutlery drawers. The Benriner at 12.25 inches fits standing up in a drawer too.

If you have the counter space, larger models like the Mueller (16.7 inches) and Gramercy (16.5 inches) give you more slicing capacity per session. But they require a dedicated cabinet spot. The DASH Safe Slice folds down to about half its open size, which is the best compromise for storage.

How to Use a Mandoline for Scalloped Potatoes?

After hundreds of batches, here’s the exact process I use with my Benriner for perfect scalloped potatoes every time. The same steps work for any mandoline on this list.

Step 1: Set the thickness dial. Dial in 3mm (1/8 inch) for russet potatoes or 2.5mm for Yukon Golds and red potatoes. Test one slice to confirm the thickness before committing to the whole potato.

Step 2: Secure the potato. Place a peeled potato in the food holder or hand guard. Make sure it’s gripped firmly. If the mandoline doesn’t have a guard, use cut-resistant gloves for the last bits.

Step 3: Slice with steady pressure. Slide the potato across the blade in smooth, even strokes. Don’t press too hard; let the mandoline do the work. A sharp blade needs minimal force.

Step 4: Stop before you reach the end. When you’re down to a small nub, stop slicing. Trying to slice the last piece is when most cuts happen. Save the nub for soup stock or compost.

Step 5: Layer immediately. Place the slices directly into your buttered baking dish with cream and cheese. Don’t let sliced potatoes sit out; they oxidize and turn brown within 20 minutes.

Mandoline vs Knife for Scalloped Potatoes

You can make scalloped potatoes without a mandoline. I’ve done it many times. A sharp knife and a steady hand will get you there, but with caveats. Hand-cut slices vary in thickness even when you’re being careful. That inconsistency means some slices cook faster than others, and you’ll end up with a dish that has both mushy and undercooked bites.

A mandoline guarantees uniform slices. Every piece is exactly the same thickness, which means every piece cooks at the same rate. The result is the layered, evenly-cooked scalloped potatoes you see in restaurants. If you make scalloped potatoes more than twice a year, a mandoline pays for itself in saved time and better results.

That said, a mandoline isn’t for everyone. If you only make scalloped potatoes for special occasions and don’t mind the extra prep time, a sharp chef’s knife works fine. The most important thing is using a consistent slicing method, whether that’s a mandoline or a knife with a thickness guide.

Frequently Asked Questions

Final Verdict: Which Mandoline Should You Buy for Scalloped Potatoes?

After testing nine mandoline slicers on hundreds of pounds of potatoes, my top pick for the best mandoline slicer for scalloped potatoes is the Benriner Japanese Mandolin Vegetable Slicer. It’s the highest-rated model in this roundup, has the sharpest blade out of the box, and its removable blades mean it will last for years. For most home cooks making scalloped potatoes regularly, this is the one to buy.

If you’re working with a tighter budget, the Mueller Austria Mandoline Slicer is the best value pick at a lower price point with 5 interchangeable blades and over 37,000 positive reviews. For safety-first cooks, the DASH Safe Slice Mandoline is the only model I tested where your hands never approach the blade. For larger batches and frequent use, the OXO Good Grips V-Blade Mandoline offers more versatility with multiple blade styles.

Whichever mandoline you choose, remember the three rules that transformed my scalloped potatoes: slice at 3mm for classic layers, wear cut-resistant gloves for the last scraps, and use Yukon Golds if you want the cleanest presentation. Once you nail those three things, you’ll never go back to hand-cutting. Try one of the picks above and your next batch of scalloped potatoes will be the best one yet.
