Preheat Oven:
Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it.
Mix Dry Ingredients:
In a large bowl, whisk together the flour, baking soda, and salt. If using sugar or other dry add-ins, mix them in now.
Incorporate Buttermilk:
Gradually add the buttermilk to the dry ingredients, stirring with a wooden spoon or spatula until a rough dough forms. Avoid overmixing.
Shape the Dough:
Turn the dough out onto a lightly floured surface. Knead gently for about 1 minute to bring it together. Shape it into a round loaf, about 1 1/2 inches thick.
Score the Top:
Place the dough on the prepared baking sheet. Using a sharp knife, score a deep cross on the top of the loaf. This helps the bread bake evenly and allows it to expand.
Bake:
Bake for 40-50 minutes, or until the bread is golden brown and sounds hollow when tapped on the bottom.
Cool and Serve:
Let the bread cool slightly before slicing. Serve warm or at room temperature with butter or your favorite spread.
