Crisp on the outside, fluffy on the inside, and bursting with tangy flavor, sourdough biscuits are a delicious addition to any meal. Whether you prefer them freshly baked or enriched through fermentation, this recipe offers versatility and simplicity for every baker.

Ideal for breakfast spreads, quick dinners, or a comforting snack, these biscuits use a sourdough starter discard for a subtle tang. Ready in under an hour or enhanced overnight, they adapt to your schedule with ease.
The Essentials for Perfect Sourdough Biscuits
- Unsalted Butter – Adds richness and creates tender layers when kept cold.
- Sourdough Starter Discard – Infuses tangy flavor and serves as a natural leavening agent.
- All-Purpose Flour – A versatile base, offering structure. Low-protein varieties yield the fluffiest texture.
- Buttermilk – Activates the baking soda and contributes to the biscuits’ signature tang.
- Baking Powder & Baking Soda – Ensure light, airy biscuits by boosting rise during baking.
- Fine Sea Salt – Enhances flavor, balancing tangy and buttery notes.
Making the Dough: Simple Steps to Success
- For Immediate Baking
Combine grated cold butter and flour to form a crumbly mixture. Mix in the sourdough discard, buttermilk, sugar (if desired), and leavening agents until just combined. Let the dough rest briefly. - For Overnight Fermentation
Follow the same process but exclude baking powder and baking soda initially. Ferment the dough overnight, then fold in leavening agents before shaping for baking. - Shaping and Baking
Flatten the dough into a 1-inch-thick rectangle, cut out rounds, and arrange them closely in a skillet or baking sheet. Bake until golden and aromatic.

Tips for Biscuit Perfection
For a lofty rise, avoid twisting your biscuit cutter; press straight down to maintain clean edges. Using low-protein flour ensures a delicate crumb, while fermenting overnight develops deeper flavor. Adjust hydration levels slightly depending on your starter’s consistency.
Storing and Reheating Leftovers
To keep your biscuits fresh, store them in an airtight container at room temperature for up to two days. For longer storage, freeze individually wrapped biscuits for up to three months. Reheat in a 350°F (175°C) oven for 10 minutes to restore their warm, flaky texture.
Enjoy these sourdough biscuits with your favorite spreads, alongside hearty soups, or simply on their own. Their delightful tang and buttery crumb will keep you reaching for another!
