If you maintain a sourdough starter, you know the guilt of discarding that bubbly excess before each feeding. But what if those discards became golden, buttery biscuits instead? Freezer-to-oven sourdough biscuits are the answer: they use your discard efficiently, can be made in batches and frozen for weeks, and go straight from freezer to oven without thawing. You’ll have fresh, fluffy biscuits ready whenever you need them.
How to Make Sourdough Discard Biscuits
This recipe transforms sourdough starter discard into tender biscuits you can freeze and bake anytime. The process takes about 45 minutes of active work, with most time spent chilling and shaping.
Ingredients
- 1 cup sourdough starter discard (unfed, at room temperature)
- 2 cups all-purpose flour
- 1 tablespoon sugar
- 1.5 teaspoons salt
- 1.5 teaspoons baking powder
- 6 tablespoons cold butter (cut into small cubes)
Method
Combine dry ingredients
In a large mixing bowl, whisk together flour, sugar, salt, and baking powder. Make sure the salt and baking powder are evenly distributed throughout the flour to avoid bitter or uneven spots in your biscuits.
Work in cold butter
Add the cold butter cubes to the flour mixture and use a pastry cutter or your fingertips to break the butter into pea-sized pieces. Work quickly so the butter stays cold–this creates steam pockets that make biscuits flaky. Stop when the mixture resembles coarse breadcrumbs.
Add sourdough discard
Pour in the sourdough discard and gently fold it into the dry mixture using a spatula or wooden spoon. Stir just until the dough comes together and no dry flour remains. Overmixing develops gluten and makes tough biscuits, so handle the dough minimally.
Chill the dough
Turn the dough onto a lightly floured work surface and refrigerate for at least 30 minutes in a covered container. This resting period allows the gluten to relax and helps the butter firm up again, both crucial for tender, flaky results.
Shape the biscuits
Remove chilled dough from the fridge and pat it into a 3/4-inch-thick rectangle. Using a round cutter, cut out biscuits and place them on a parchment-lined baking sheet, leaving about 2 inches between each one. Gather scraps gently, pat again, and cut more biscuits until all dough is used.
Freeze before baking
Place the baking sheet with shaped biscuits in the freezer for at least 2 hours, or until fully frozen. Once frozen solid, transfer biscuits to a freezer bag and store for up to 1 month. This freezing step actually improves texture by keeping the butter cold during baking.
Bake from frozen
Preheat your oven to 400°F. Arrange frozen biscuits on a baking sheet and bake for 18-22 minutes, or until the tops are light golden brown. Do not thaw; they bake perfectly straight from the freezer.
Cool and serve
Remove biscuits from the oven and let them cool on a wire rack for 5 minutes before serving. They taste best warm, but can be reheated wrapped in foil at 350°F for 8-10 minutes.
- Keep all ingredients cold before mixing–especially the butter. Chill your bowl and even your flour for 15 minutes before starting if your kitchen is warm.
- Don’t skip the sourdough starter’s tang by using cooked discard. The slight sourness complements the buttery richness and adds complexity to the flavor.
- For extra-fluffy biscuits, brush the tops with melted butter or an egg wash before freezing, then freeze before baking. This gives them a beautiful golden crust.
What to Look For in Biscuit-Making Equipment
- Pastry cutter or bench scraper: A tool that cuts butter into flour without warming it. Look for one with multiple blades or a sturdy handle that gives you leverage without requiring much hand pressure, which generates heat.
- Biscuit cutter (round or fluted): A sharp-edged cutter in the 2-3 inch diameter range produces classic biscuits. Fluted edges look professional; plain edges are simpler. Ensure the cutter has a sharp rim so it cuts cleanly without compressing the edges.
- Wire cooling rack: Allows air to circulate under biscuits so they cool evenly and don’t steam themselves into dense pucks. A rack with small grid spacing prevents biscuits from falling through.
- Parchment paper or silicone baking mat: Prevents sticking and browning on the bottom of biscuits. Parchment is disposable and convenient; reusable silicone mats are eco-friendly and work equally well for even baking.

Frequently Asked Questions
Can I bake the biscuits without freezing them first?
Yes, but freezing improves the texture significantly. If you want to bake fresh, chill the shaped biscuits for at least 2 hours before baking at 400°F for 15-18 minutes. The longer rest time allows the gluten to relax and keeps the butter cold during baking.
How long do frozen sourdough biscuits last?
Frozen sourdough biscuits stay fresh for up to one month when stored in an airtight freezer bag. After one month, they’re still safe to eat but may develop freezer burn or lose some texture quality. Label your bag with the date so you know when to use them.
What if my sourdough discard is too thick or too thin?
Sourdough discard consistency varies widely. If it’s too thick (like pancake batter), whisk in a teaspoon of water at a time until it becomes pourable. If it’s too thin (like heavy cream), add a tablespoon of flour and let it rest for 10 minutes before mixing into the dough.
Do I need to feed my sourdough starter before using the discard?
No. For this recipe, use discard from your regular feeding–the kind you’d throw away anyway. Using freshly fed discard with active bubbles will actually make the biscuits rise too much and become fluffy rather than flaky.
Can I make these biscuits vegan?
Yes. Replace the butter with a vegan butter or coconut oil (keep it cold), and use the same amount. The texture will be slightly different–coconut oil makes them crispier, while vegan butter mimics traditional results most closely.
