How to Make Gluten-Free Biscuits That Rise and Taste Great

A good biscuit tears open in soft layers, steams a little, and tastes like butter and buttermilk. Gluten-free versions usually arrive flat, pale, and gritty — not because gluten-free baking is hopeless, but because the recipe asks flour to do something it cannot do alone. Adjust three things — the blend, the binder, and the amount of liquid — and you can pull biscuits out of the oven that stand past an inch tall and taste like the ones you remember.

Why Gluten-Free Biscuits Fall Flat

Gluten does two jobs in a biscuit. It forms a stretchy network that traps the gas baking powder releases, and it gives the dough enough structure to hold its shape until the starches set. Take it away and the dough has nothing to lean on, so it spreads before it rises.

There is a second problem that catches most bakers: gluten-free flours absorb water slowly. Mix a batter and bake it immediately, and the flours pull liquid out of the dough while it bakes, leaving a dry, crumbly interior. Rice flours also taste gritty until they have had time to hydrate fully. So the fix is not one ingredient — it is structure, liquid, and time.

Start With a Blend That Can Hold Its Shape

Not all one-to-one blends behave the same. Read the ingredient list before you buy. The blends that make tall, tender biscuits combine whole grains — brown rice, sorghum, millet, oat — with starches like tapioca, cornstarch, or potato starch. Aim for roughly 60 percent whole grain to 40 percent starch.

• Good signs: sorghum, brown rice, millet, oat flour, and a starch listed in the first four ingredients.
• Watch out for: blends built almost entirely on white rice and starch. They taste bland and bake up sticky.
• Bean flours (garbanzo, fava) add protein but brown quickly and can leave a beany aftertaste in a buttery biscuit.
• Check for xanthan gum. If the blend already contains it, do not add more.

Binders and Fat Do the Work Gluten Used to Do

If your blend lacks a gum, add half a teaspoon of xanthan gum per cup of flour. Xanthan mimics gluten's stretch and keeps the crumb from shattering. Psyllium husk powder, about one teaspoon per cup plus an extra tablespoon of liquid, gives a chewier, more bread-like biscuit. Ground flax and chia work too, but they add flavor and a slightly gummy texture, so use them in heartier versions with cheese or herbs.

Fat matters just as much. Grate frozen butter on a box grater straight into the dry ingredients, then toss until every shred is coated. Those butter flakes create steam pockets as they melt, which is where flaky layers come from. Cold buttermilk does double duty: its acid reacts with baking soda for lift, and its fat tenderizes the crumb.

Hydration and Resting: Two Quiet Fixes

Gluten-free dough needs more liquid than wheat dough — often 15 to 25 percent more. You want a shaggy, slightly sticky mass that holds together when you scoop it. If it looks like cookie dough, add buttermilk a tablespoon at a time.

Then walk away. Cover the bowl and let the dough rest for at least 15 minutes, 30 if you have the patience. During that time the flours finish absorbing liquid, the grit softens, and the binder activates. A short rest in the refrigerator also re-firms the butter, which pays off in the oven.

The squeeze test

Grab a handful of rested dough and squeeze. If it holds its shape and leaves only a light film on your palm, you are ready. If it crumbles, add buttermilk. If it coats your whole hand, sprinkle in flour by the tablespoon.

The Recipe: Tall Gluten-Free Buttermilk Biscuits

Makes 6 to 8 biscuits, depending on your cutter.

• 2 cups (280 g) gluten-free flour blend
• 1 tablespoon baking powder
• 1/2 teaspoon baking soda
• 1 teaspoon fine salt
• 1 tablespoon sugar (optional, for browning)
• 1/2 teaspoon xanthan gum, only if your blend lacks it
• 8 tablespoons (113 g) unsalted butter, frozen
• 1 cup cold buttermilk, plus more as needed
• 1 large egg
• 1 teaspoon apple cider vinegar

1. Whisk the flour, baking powder, baking soda, salt, sugar, and xanthan gum in a large bowl.
2. Grate the frozen butter into the dry ingredients and toss with your fingertips until coated. Keep everything cold.
3. Whisk the buttermilk, egg, and vinegar. Pour into the dry mixture and fold with a spatula just until no dry flour remains, about 10 folds. Add buttermilk by the tablespoon if it will not come together.
4. Cover and rest 20 minutes at room temperature or 30 minutes in the fridge.
5. Heat the oven to 425°F (220°C). Line a baking sheet with parchment or set a cast-iron skillet inside to preheat.
6. Turn the dough onto a floured sheet of parchment and pat to 1 inch thick. Fold it in thirds like a letter, pat back to 1 inch, and repeat once. This builds layers in place of gluten.
7. Cut straight down with a sharp cutter or a floured knife. Do not twist.
8. Brush the tops with buttermilk, then freeze the cut biscuits for 10 minutes while the oven finishes heating.
9. Bake 15 to 18 minutes, until domed and golden brown. Cool 10 minutes before splitting.

Shaping, Cutting, and Baking for Height

Three habits separate tall biscuits from flat ones. Cut with a straight push and lift the cutter out — twisting seals the edges and stops the rise. Set the biscuits close together, nearly touching, so they climb instead of spreading. And bake hot: a 425°F oven sets the outside fast while the interior steams upward.

Quick troubleshooting

• Flat: check that your baking powder is fresh, rest the dough longer, and make sure the oven is fully preheated.
• Gummy center: the dough was too wet. Reduce buttermilk by two tablespoons next time and bake a few minutes longer.
• Gritty: rest the dough 30 minutes, and sift your blend if it feels coarse.
• Crumbly: add a tablespoon of buttermilk and handle the dough less.

Make These Biscuits Yours

Sharp cheddar and chives, crumbled bacon, or a handful of blueberries tossed in flour all work well. Add-ins bring their own moisture, so cut the buttermilk by two or three tablespoons when you stir them in.

Serve them the day you bake them. To reheat, wrap in foil and warm at 350°F for six to eight minutes. For a stash, freeze cut unbaked biscuits on a sheet, then bag them; bake from frozen, adding three to five minutes.

One note if you bake gluten-free for a medical reason: use flour certified gluten-free and check every add-in, including spices and baking powder. Cross-contact in a shared kitchen is easy to miss, so keep separate tools where it matters.
