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 thoroughly combined.
03 - Create a well in the center of the dry ingredients. Pour buttermilk into the well and stir gently with a wooden spoon until a shaggy, sticky dough forms.
04 - Turn dough onto a lightly floured surface. Gently knead just until dough comes together—avoid overworking. Shape into a round, slightly flattened loaf approximately 2 inches thick. Place on prepared baking sheet.
05 - Using a sharp knife, cut a deep cross pattern across the top of the loaf. Bake for 30 to 35 minutes until golden brown and the bottom sounds hollow when tapped.
06 - Transfer loaf to a wire rack and let cool for at least 30 minutes before slicing to ensure proper texture.
