Sourdough biscuits are a revelation if you’ve only ever made traditional buttermilk versions. By incorporating your active sourdough starter and allowing the dough to cold-ferment overnight, you unlock a deeper, more complex flavor while keeping the crumb tender and flaky. The long fermentation also makes these biscuits more digestible and gives them that signature tangy sourdough character that pairs perfectly with savory spreads or morning eggs.
How to Make Long-Fermented Sourdough Biscuits
This recipe combines the rustic simplicity of biscuits with the depth of sourdough fermentation. The dough comes together quickly, then does most of the work in your refrigerator overnight.
Ingredients
- 1 cup active sourdough starter (fed 4-8 hours prior, bubbly and at peak)
- 2 cups all-purpose or bread flour
- 1/2 teaspoon fine sea salt
- 6 tablespoons cold butter, cubed
- 2-4 tablespoons ice water (as needed for hydration)
Method
Combine dry ingredients
Whisk together flour and salt in a large mixing bowl. This distributes the salt evenly and prevents it from killing your sourdough culture. Set aside.
Cut in the butter
Add cold butter cubes to the flour mixture. Using a pastry cutter or your fingertips, work the butter into the flour until the mixture resembles coarse breadcrumbs with some pea-sized pieces remaining. The cold butter creates steam pockets during baking, resulting in flaky layers.
Incorporate the starter
Pour your active sourdough starter into the flour-butter mixture. Stir gently with a wooden spoon or spatula until just combined. The dough will be shaggy and slightly wet. Do not overwork it.
Add water if needed
If the dough seems too dry to come together, sprinkle ice water one tablespoon at a time while folding gently. The dough should be cohesive but still slightly sticky, not smooth or elastic.
Cold ferment overnight
Cover the bowl with plastic wrap or transfer to a sealed container. Refrigerate for 12-18 hours. This extended fermentation develops flavor and makes the dough easier to handle. The dough will rise slightly and become more cohesive.
Shape and rest the biscuits
Remove dough from the refrigerator. Turn it out onto a lightly floured surface and gently press into a 3/4-inch thick rectangle. Cut into rounds or squares using a biscuit cutter or knife. Place on a parchment-lined baking sheet with 2 inches between each biscuit. Let rest at room temperature for 30-45 minutes.
Bake until golden
Preheat your oven to 400 degrees Fahrenheit. Bake the biscuits for 18-22 minutes until the tops are deep golden brown. The bottoms should be crispy and the interior tender. Transfer to a cooling rack for 5 minutes before serving warm with butter, jam, or gravy.
- Keep all ingredients cold, especially the butter and starter. Cold ingredients are essential for flaky layers and manageable dough.
- Don’t skip the overnight fermentation. This is what transforms ordinary biscuits into tangy, complex sourdough biscuits with superior texture.
- If your dough becomes warm or sticky while shaping, refrigerate it for 15 minutes. Cold dough is much easier to cut and shape cleanly.
What to Look For in Sourdough Biscuit Baking Equipment
- Digital Kitchen Scale: Precise measurements ensure consistent results. A scale that measures in grams and ounces helps you replicate your sourdough biscuits exactly, batch after batch.
- Pastry Cutter or Dough Blender: This tool cleanly cuts cold butter into flour without warming it up. A good pastry cutter is faster and more efficient than using your fingers and keeps your biscuits flaky.
- Biscuit Cutter or Round Cutter: A sharp cutter creates clean edges that rise properly in the oven. Dull cutters crush the dough and prevent even rise, resulting in dense biscuits.
- Instant-Read Thermometer: While biscuits are visually done when golden, an instant-read thermometer ensures the interior reaches 200-205 degrees Fahrenheit for perfect doneness.

Frequently Asked Questions
Can I make these biscuits without a sourdough starter?
Not in the traditional sense, as the starter is essential to the recipe. However, you could create a quick starter using flour, water, and a bit of commercial yeast, though it won’t develop the complex sourdough flavor. For authentic results, cultivate a starter at least 7-10 days in advance.
What if my starter isn’t doubling or bubbling?
Your starter needs to be at peak activity when incorporated. Feed it 4-8 hours before baking and wait until it’s visibly bubbly and has increased in volume. If it’s not active enough, feed it daily for 5-7 days until it shows consistent rise and fall patterns.
How should I store leftover biscuits?
Store cooled biscuits in an airtight container at room temperature for up to 2 days, or freeze in a freezer bag for up to 3 months. Reheat in a 350-degree oven for 10 minutes until warm and crispy again.
Why are my biscuits coming out dense instead of fluky?
Overworking the dough, using warm butter, or crushing the dough edges with a dull cutter are common culprits. Keep all ingredients cold, handle the dough minimally, and use a sharp cutter. Also ensure your oven is fully preheated to 400 degrees.
Can I skip the overnight fermentation and bake the same day?
You can, but you’ll lose the distinctive tangy sourdough flavor that makes these special. If you’re short on time, ferment for at least 4-6 hours in the refrigerator, though overnight gives superior results.
