Preheat oven to 400℉. Line a baking sheet with parchment paper or grease well; set aside. You can also use an 8" cake pan or oven proof skillet.

In a large bowl whisk together the flour, baking soda, and salt. Stir in the buttermilk just until combined and it starts to become too stiff to stir. Transfer to work surface and with floured hands lightly knead the dough 5-10 times or until all the flour is moistened and the dough comes together.

Form dough into an 8" round. Place on the prepared pan and with a very sharp knife, cut a ¼-½" deep X on the top. Bake for 45-50 minutes or until golden brown, and it sounds hollow when tapped on the bottom. The loaf is also done when an instant read thermometer reads the center of the loaf at 195℉.
