Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

In a large mixing bowl, combine the flour, baking soda, and salt. Whisk together until well combined.

Make a well in the center of the dry ingredients and pour in the buttermilk.

Using your hands or a wooden spoon, mix the ingredients together until a soft dough forms. Be careful not to overmix; a light touch is key.

Turn the dough out onto a lightly floured surface and shape it into a round loaf, about 1.5 inches thick.

Transfer the loaf to the prepared baking sheet. Using a sharp knife, score a deep cross on the top of the dough to allow it to expand while baking.

Bake in the preheated oven for 30-35 minutes, or until the bread is golden brown and sounds hollow when tapped on the bottom.

Remove from the oven and let cool on a wire rack before slicing.
