Preheat oven to 400F (205C) and line a baking sheet with parchment paper. Set aside.

In a large bowl, whisk together flour, sugar, baking soda, and salt.

Make a well in the center and add 1 cup of buttermilk and olive oil. Whisk together in the well and gradually stir into the flour mixture. Add remaining buttermilk as needed until dough clings together and you have a shaggy dough.

Transfer to a clean, lightly floured surface and briefly knead dough several times (don’t over-do it) and form dough into a round ball. It will be a bit shaggy and a bit sticky. Transfer to prepared baking sheet and lightly flatten with your hands. Use a sharp knife to score a deep (about halfway into the center of the bread) “X” into the top center of the bread.

Transfer to 400F (205C) oven and bake for 35-40 minutes and bread sounds hollow when tapped.

Allow to cool then slice and enjoy.
