There’s something quietly satisfying about turning something you might toss — a spoonful of sourdough starter discard — into warm, flaky biscuits that disappear in minutes. If you keep a starter on the counter, you know the guilt of throwing away discard. These biscuits are my little rebellion against food waste: simple, forgiving, and utterly addictive. If you want a sweet use for leftover starter, try the sourdough discard cinnamon rolls.
Why You’ll Love These Sourdough Biscuits
They’re light but sturdy enough to hold butter and jam. The starter adds a pleasant, subtle tang that brightens the rich, buttery flavor. Best of all, they’re fast: a few minutes of mixing, a short chill, and you’re baking. If you’re making biscuits for the first time, this recipe is kind — it forgives a rough roll and still gives you good layers.
On busy mornings you might swap biscuits for easy scones like these sourdough pumpkin muffins.
Ingredients
- 2 cups (250 g) all-purpose flour, plus extra for dusting
- 1 tablespoon baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon fine sea salt
- 2 tablespoons granulated sugar (optional)
- 6 tablespoons (85 g) cold unsalted butter, cubed
- 3/4 cup (180 g) sourdough starter discard (unfed, room temperature)
- 1/4 to 1/3 cup (60–80 ml) cold whole milk or buttermilk
- 1 large egg (for egg wash, optional)
How to Make Sourdough Biscuits
Follow these steps for flaky layers and tender crumbs. I’ll include a few little tricks that save you from overworking the dough — the key to good biscuits.
1. Preheat and prep
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment and chill it in the fridge if you like — a cold surface helps keep the butter from melting too quickly.
2. Mix the dry ingredients
In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar. These will give the biscuits their rise and light texture.
3. Cut in the butter
Scatter the cold cubed butter over the flour. Using a pastry cutter, two knives, or your fingertips, work the butter into the flour until the mixture looks like coarse crumbs with pea-sized bits of butter. Those little lumps of butter are what create the flaky layers when they steam in the oven.
4. Add starter and milk
Stir in the sourdough discard. It will be thick and slightly tangy. Add 1/4 cup (60 ml) cold milk and fold gently until the dough starts to clump. If it’s too dry, add the remaining milk tablespoon by tablespoon. The dough should hold together but still be slightly shaggy — don’t overmix.
5. Fold for layers
Turn the dough onto a lightly floured surface. Pat it into a rectangle about 3/4-inch thick. Fold it over on itself three times (fold like a letter). This simple fold creates layers without heavy rolling. Pat it out to 1-inch thickness for taller biscuits or 3/4-inch for quicker baking.
6. Cut and chill
Use a floured 2 1/2-inch biscuit cutter or a glass to stamp out rounds. Press straight down — don’t twist. Gather scraps and repeat until you have 8–10 biscuits. For the best rise, chill the cut biscuits on the baking sheet for 10–20 minutes while the oven finishes heating.
7. Bake
Brush the tops with a little beaten egg or milk for a golden finish if you like. Bake at 425°F (220°C) for 12–15 minutes, until the tops are puffed and golden brown. Let cool a few minutes on the pan — they’ll be easier to split when slightly cooled.
Tips & Variations
- For cheesy biscuits, fold in 1/2 cup grated cheddar before shaping.
- Add 1 tablespoon finely chopped fresh herbs (chives, rosemary) to the dry mix for savory flavor.
- Press the biscuits together on the pan (touching) for soft sides, or space them apart for crisp edges.
- These biscuits are also fantastic with a saucy main like honey butter chicken.
Serving
Split warm and slather with butter and honey, or use them for breakfast sandwiches with eggs and bacon. They also make a lovely side to stews and roast chicken. Serve these biscuits alongside warm sourdough french toast for a weekend brunch your family will remember.
FAQs
Can I use active starter instead of discard?
Yes. If your starter is active and bubbly, reduce the milk slightly since active starter is thinner. The flavor will be tangier and livelier.
Do I need to chill the dough?
Chilling helps keep the butter cold so you get flakier layers. If you’re short on time, you can bake immediately — just expect slightly less dramatic layers.
Can I make these dairy-free?
Substitute cold coconut oil or a vegan butter in the same quantity and use a plant-based milk. The texture will be slightly different but still delicious.
What can I do with leftover starter?
Besides these biscuits, leftover starter is great in quick bakes and pancakes. If you want a sweet option, try sourdough discard cinnamon rolls for dessert or brunch.
Conclusion
These sourdough biscuits strike a nice balance: simple technique, forgiving dough, and a flavor that hints at something more than plain biscuits. They’re a tiny weekend triumph when you pull a tray of golden rounds from the oven and watch everyone reach for the butter. If you like experimenting with discard, you might also enjoy baking sourdough pumpkin muffins for mornings when you want something sweet, or pairing your biscuits with hearty mains — try serving them with honey butter chicken for a comforting meal. And for a lazy brunch, warm biscuits alongside sourdough french toast make an indulgent spread.
Go ahead — dig in. The first biscuit is always the best, but there’s no shame in having a second.
