These gluten-free buttermilk biscuits follow the Southern method: cold fat is cut into the dry ingredients, cold buttermilk is stirred in just until a soft dough forms, and the rounds are baked in a hot oven. The dough has no egg and no sugar. Xanthan gum takes over the job that gluten does in a wheat biscuit and keeps the crumb from falling apart.
The fat is a matter of preference. Butter gives the most flavor, shortening or lard gives a slightly taller and more tender biscuit, and a half-and-half combination sits in between. All of them are used in the same amount, and all of them must be cold so that small pieces of fat survive in the dough and melt into flaky pockets in the oven.
Gluten-free flours take up liquid more slowly than wheat flour, so the dough should look a little wetter than a wheat biscuit dough; it firms up as it is patted and folded. Use a blend without added gum, such as this gluten-free all-purpose flour blend, or leave out the xanthan gum if the blend already contains it.

Gluten-Free Southern Buttermilk Biscuits
Ingredients
Method
- Heat the oven to 425°F. Line a baking sheet with parchment paper.
- In a large bowl, whisk together the 2 cups flour blend, xanthan gum, baking powder, baking soda and salt.
- Add the cold butter cubes. Cut them in with a pastry blender or two knives, or rub them in quickly with your fingertips, until the largest pieces are about the size of peas.
- Pour in 3/4 cup cold buttermilk and stir with a fork just until a soft, slightly sticky dough forms. If dry crumbs remain in the bottom of the bowl, add more buttermilk 1 tablespoon at a time, up to 1/4 cup.
- Turn the dough out onto a surface dusted with flour blend. Pat it into a rectangle about 3/4 inch thick, fold it in thirds like a letter, and pat it out again. Repeat the fold once more, then pat the dough out 1 inch thick.
- Cut out biscuits with a floured 2-inch round cutter, pressing straight down without twisting. Gently press the scraps together, pat out and cut again. There should be about 8 biscuits.
- Set the biscuits on the baking sheet with their sides just touching. Brush the tops with the 1 tablespoon buttermilk.
- Bake for 15 to 18 minutes, until well risen and golden on top. Cool on the sheet for 5 minutes and serve warm.
