If you’ve got sourdough starter on hand, you have the secret ingredient for an exceptionally flaky pie crust with subtle tang. Instead of discarding that excess starter, redirect it into a tender, buttery crust that works beautifully for both sweet and savory pies. This recipe captures the complexity of sourdough baking in a simpler form, requiring just a few basic ingredients and a little patience between steps.
How to Make Sourdough Pie Crust
This method yields one 9-inch single crust or enough for a double-crust pie when doubled. The sourdough discard adds moisture and flavor while the cold fat creates those coveted flaky layers.
Ingredients
- 1 cup active sourdough discard (fed and bubbly)
- 2.5 cups all-purpose flour
- 1 tablespoon granulated sugar
- 1 teaspoon fine sea salt
- 10 tablespoons cold unsalted butter, cubed
- 3-5 tablespoons ice water (as needed)
Method
Combine dry ingredients
In a large mixing bowl, whisk together the flour, sugar, and salt until evenly distributed. These dry ingredients form the base structure of your crust. Make a shallow well in the center of the mixture for your wet ingredients.
Cut in the cold fat
Add the cubed cold butter to the flour mixture. Using a pastry cutter, two forks, or your fingertips, work the butter into the flour until the mixture resembles coarse breadcrumbs with pea-sized pieces of butter visible throughout. These pockets of cold fat are crucial for achieving flakiness.
Add sourdough discard and mix
Pour your active sourdough discard into the well and gently mix with a fork, pulling in flour from the sides until the dough begins to come together. Add ice water one tablespoon at a time if the dough feels too dry. You want a shaggy, slightly moist dough that holds together when pressed.
Rest and chill the dough
Form the dough into a disk, wrap it tightly in plastic wrap, and refrigerate for at least 2 hours, though overnight is ideal. This resting period allows the flour to fully hydrate and the gluten to relax, making the dough easier to roll and more tender when baked.
Roll out the crust
On a lightly floured surface, roll the chilled dough into a thin circle about 11 inches in diameter for a 9-inch pie pan. Work gently to avoid overworking the gluten. If the dough cracks at the edges, pinch it back together as you go.
Transfer and shape
Carefully transfer the rolled dough to your pie pan, letting excess hang over the edge. Trim or fold under the edges as desired, then crimp with your fingers or a fork for a finished look. For a blind bake, prick the bottom with a fork to prevent puffing.
Chill before baking
Place the shaped crust in the freezer for 15-30 minutes before baking. This final chill ensures the butter stays cold during the initial baking, creating maximum steam and flakiness. If preparing in advance, freeze the unbaked crust for up to 1 month.
Bake according to filling
For a blind bake (unfilled crust), bake at 425°F for 12-15 minutes until light golden. For a filled pie, bake at your recipe’s specified temperature, covering the edges with foil if browning too quickly. The sourdough flavor will develop beautifully during baking.
- Keep all ingredients cold, especially the butter and water. Chill your mixing bowl if your kitchen is warm.
- Resist the urge to overwork the dough after adding the sourdough discard. Mix until just combined; overmixing develops gluten and toughens the crust.
- For extra tang, use sourdough discard that’s been at room temperature for 4-6 hours after feeding, when fermentation is most active.
Essential Tools for Making Pie Crust
- Pastry Cutter or Blender: This tool efficiently cuts cold butter into flour without warming it with your hands. A pastry blender’s multiple wires or a pastry cutter’s flat design both work well for creating the coarse crumb texture essential to flaky crusts.
- Rolling Pin: A sturdy rolling pin with good weight distribution makes expanding dough evenly easier and faster. Look for one with a comfortable handle and even surface to prevent sticking and uneven thickness.
- Pie Pan: A 9-inch ceramic, glass, or metal pie pan conducts heat evenly for consistent browning. Glass and ceramic let you monitor crust color from below, while metal pans are lightweight and durable for frequent bakers.
- Digital Scale: Measuring by weight rather than volume ensures consistency, especially important in sourdough baking where starter hydration varies. A kitchen scale removes guesswork from ingredient ratios for reliable results.

Frequently Asked Questions
Can I use frozen sourdough discard in my pie crust?
Yes, thaw frozen discard to room temperature before using. The thawing process may activate additional fermentation, which can actually enhance the tangy flavor. Just ensure it’s at room temperature so it mixes properly with other ingredients.
How much sourdough discard should I feed before using it?
Feed your starter 4-8 hours before making the crust and wait until it’s bubbly and active at peak rise. An active, recently fed starter incorporates more fermentation flavor and moisture into your crust.
Can I make this crust without a pastry cutter?
Absolutely. Use two forks, your fingertips, or even two butter knives to cut the cold butter into pea-sized pieces. The goal is keeping the butter cold and separate from the flour; the tool is just a means to that end.
What’s the difference between blind baking and regular baking?
Blind baking (pre-baking the empty crust) prevents soggy bottoms in custard or cream pies. Regular baking happens when you fill the crust first. Follow your specific pie recipe’s instructions for which method to use.
How long can I store an unbaked sourdough pie crust?
Wrap the shaped crust tightly and freeze for up to one month. Bake from frozen; add 5-10 minutes to the baking time. You can also refrigerate it for up to three days, though freezing is recommended for best texture.
