Sourdough Biscuits: Flaky, Tangy & Oh-So-Buttery

If there’s one thing that brings folks together, it’s a hot, buttery biscuit fresh outta the oven. Now take that Southern staple, stir in some tangy sourdough starter, and what do you get? The flakiest, most tender sourdough biscuits this side of the Mississippi. These sourdough discard biscuits are golden on the outside, soft on the inside, and packed with real down-home flavor.

I’ll never forget the first time I slipped sourdough discard into my biscuit dough. It was a lazy Sunday, and I had a big ol’ jar of starter that needed usin’. Meemaw always said, “Waste not, want not,” so I figured—why not? That little scoop of sourdough gave the biscuits a gentle tang that made everybody at the table slow down, close their eyes, and savor every single bite.

Now, Southern-style sourdough biscuits are a must in my kitchen. Whether they’re piled high in a bread basket for company, stacked with eggs and sausage for breakfast, or served alongside a pot of stew, they never last long. So grab your apron and your starter—we’re about to bake up a batch of buttermilk sourdough biscuits that just might make angels sing.

Biscuits ain’t hard, but they do need a little know-how. The secret? Cold ingredients, a gentle touch, and a healthy scoop of love. Adding sourdough starter or sourdough discard brings:

• More flavor: A subtle tang that makes each bite more interesting.
• Better texture: Sourdough helps create tender, flaky layers.
• Less waste: A perfect way to use up extra sourdough discard.
• More versatility: These buttermilk sourdough biscuits work for breakfast, brunch, or dinner.

As long as you keep the butter cold and don’t overwork the dough, these easy sourdough biscuits will rise tall, fluffy, and proud.

This simple biscuit recipe uses pantry staples plus your sourdough starter.

• 2 cups all-purpose flour
• 1 tablespoon baking powder
• 1/2 teaspoon baking soda
• 1 teaspoon salt

• 6 tablespoons unsalted butter, cold and cubed
• 1 cup sourdough starter (discard or active, at room temperature is fine)
• 1/2 cup cold buttermilk (plus extra for brushing tops)

• 1/2 cup shredded sharp cheddar cheese
• 1 teaspoon cracked black pepper
• 2 tablespoons fresh herbs (chives, rosemary, or thyme), finely chopped

Tip: If you don’t have buttermilk, you can make a quick version by mixing 1/2 cup milk with 1/2 tablespoon vinegar or lemon juice. Let it sit for 5–10 minutes before using.

Follow these easy steps and you’ll have fresh sourdough buttermilk biscuits on the table in no time.

1. Chill Your Ingredients

   Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper. Make sure your butter is very cold—if it’s starting to soften, pop it in the freezer for 5–10 minutes. Cold butter is what creates those gorgeous, flaky layers.

2. Combine Dry Ingredients

   In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt. If you’re using cheese, herbs, or black pepper, add them now and toss to coat. This keeps everything distributed evenly in the dough.

3. Cut in the Butter

   Add the cold, cubed butter to the flour mixture. Use a pastry cutter, fork, or your fingertips to work the butter into the flour until it looks like coarse crumbs with some pea-sized bits of butter still visible. Don’t overdo it—those little chunks of butter are what puff up and create layers as the biscuits bake.

4. Add Sourdough Starter and Buttermilk

   Pour in the sourdough starter and most of the cold buttermilk. Gently stir with a spatula or wooden spoon just until the dough starts to come together. If it seems too dry, add a splash more buttermilk; if it’s too sticky, sprinkle in a tiny bit more flour. The dough should be soft and slightly shaggy, not wet or heavy.

5. Fold the Dough for Flaky Layers

   Turn the dough out onto a lightly floured surface. Gently pat it into a rectangle about 1 inch thick. Fold the dough in half like a book, rotate it 90 degrees, and pat it back into a rectangle. Repeat this folding process 3–4 times. This stacking and folding is what builds those beautiful, tall, flaky sourdough biscuit layers.

6. Cut the Biscuits

   After the final fold, pat or gently roll the dough to about 3/4-inch thickness. Use a biscuit cutter or a sharp round cutter dipped in flour to cut out biscuits. Press straight down without twisting (twisting seals the edges and keeps them from rising as high). Place the biscuits close together on the prepared baking sheet so they help each other rise.

7. Bake to Golden Perfection

   Brush the tops with a little extra buttermilk for a pretty golden finish. Bake for 12–15 minutes, or until the biscuits are puffed and golden brown on top. Let them cool for a few minutes on the pan, then serve warm while the butter still melts right into them.

These homemade sourdough biscuits are endlessly versatile. Try serving them:

• Split open with honey butter, jam, or preserves.
• Smothered in sausage gravy for a classic Southern breakfast.
• As the base for a fried chicken biscuit sandwich.
• Alongside a bowl of chili, stew, or soup to soak up all the goodness.
• With eggs, bacon, and cheese for an easy breakfast biscuit.

No matter how you serve them, these tangy, flaky sourdough buttermilk biscuits are pure comfort food.

• To make ahead: Prepare and cut the biscuits, then place them on a baking sheet and refrigerate for up to 24 hours. Bake straight from the fridge, adding a minute or two if needed.
• To freeze unbaked biscuits: Freeze cut biscuits on a tray until solid, then transfer to a freezer bag. Bake from frozen at 425°F, adding 3–5 extra minutes.
• To store baked biscuits: Keep cooled biscuits in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days.
• To reheat: Warm in a 300°F oven for 5–10 minutes, or split and toast in a skillet with a little butter.

• Your butter may have been too warm.
• The dough might have been overworked.
• Your baking powder could be old—check the date!

• Use fresh baking powder and don’t pack your flour when measuring.
• Handle the dough gently and stop mixing as soon as it comes together.
• An active, recently fed sourdough starter or fresh discard works best.

• Make sure the butter is very cold before you start.
• Don’t skip the folding step—those layers don’t build themselves!
• Resist the urge to roll the dough too thin; aim for 3/4 inch.

Remember, baking’s a journey. Even the “mistakes” usually taste mighty fine—especially with a little butter and jam.

Yes! Cold sourdough discard works just fine in this recipe. If it’s very stiff, let it sit at room temperature for 10–15 minutes so it’s easier to mix in.

Absolutely. Use regular milk with a splash of vinegar or lemon juice, or swap in plain yogurt thinned with a bit of milk for that classic tangy flavor.

Nope. This is a great sourdough discard recipe. The baking powder and baking soda do most of the lifting, while the starter brings flavor and tenderness.
