Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.

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

Gradually pour in the buttermilk, stirring until a soft dough forms. The dough may be a little sticky.

Turn the dough onto a lightly floured surface and knead gently for 1-2 minutes. Shape it into a round loaf.

Place the loaf on the prepared baking sheet. Score an “X” on top with a sharp knife to help the bread rise evenly.

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

Let the bread cool on a wire rack for at least 15 minutes before slicing.
