01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or dust lightly with flour.
02 - In a large mixing bowl, whisk together flour, baking soda, and salt until evenly distributed.
03 - Create a well in the center of the flour mixture. Pour in buttermilk and stir with a wooden spoon until shaggy dough forms.
04 - Turn dough onto a lightly floured surface. Knead gently just until it comes together, avoiding overworking. Shape into a round, flattened loaf about 2 inches thick.
05 - Place loaf on prepared baking sheet. Using a sharp knife, cut a deep X across the top to help the bread expand during baking.
06 - Bake for 30 to 35 minutes until golden brown and the bottom sounds hollow when tapped.
07 - Transfer to a wire rack and cool for at least 30 minutes before slicing to preserve texture.
