If you bake regularly with sourdough, you know that sourdough discard can pile up quickly. Instead of tossing it out, you can transform this byproduct into a quick and flaky crust that works beautifully for both sweet and savory pies or quiches. This recipe uses simple ingredients and a straightforward method to create a crust that’s tender, buttery, and full of flavor.
Ingredients:
315g all-purpose flour
9g salt
283g cold butter
300g sourdough discard
21g honey
*makes enough for 2 crusts or top & bottom
Instructions:
1. Mix Dry Ingredients
Start by combining the flour and salt in a large bowl. Mixing these first ensures even distribution of salt throughout the dough.
2. Add Cold Grated Butter
Grate the cold butter directly into the flour mixture. Using grated butter speeds up the process and helps keep the butter cold, which is crucial for a flaky texture. Use your fingers or a pastry cutter to gently mix the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces.
3. Pour in Wet Ingredients
Add the sourdough discard and honey to the dry mixture. Stir gently until the dough just comes together. AVOID over-mixing to prevent a tough crust.
4. Chill the Dough
Wrap the dough in plastic wrap and chill it in the refrigerator for at least 30 minutes. This resting period allows the gluten to relax and the butter to firm up again, which helps maintain flakiness during baking.
Baking Tips and Timing
Preheat your oven to 350°F (175°C). This moderate temperature ensures the crust cooks evenly without burning.
Roll out the dough on a lightly floured surface to your desired thickness.
Use half the dough for the bottom crust and the other half for the top crust if making a double-crust pie.
Follow your pie or quiche filling recipe’s baking instructions, typically around 45 minutes, but adjust as needed based on your filling’s requirements.
If you want a crisper crust, you can blind bake the bottom crust for 10-15 minutes before adding the filling.
Versatility of This Crust
This sourdough discard crust is incredibly versatile. Its balanced flavor and flaky texture make it perfect for:
Sweet pies like apple, cherry, or pumpkin. The honey adds a subtle sweetness that enhances fruit fillings.
Savory pies such as chicken pot pie. The slight tang from the sourdough discard complements rich, creamy fillings.
Quiches with spinach, cheese, and bacon or mushrooms and herbs. The crust holds up well to moist fillings without becoming soggy.
Why Use Sourdough Discard in Pie Crust?
Many bakers discard sourdough starter regularly, but this recipe turns that waste into a delicious asset. The discard adds moisture and a mild tang that enriches the crust’s flavor without overpowering it. Plus, it reduces food waste and makes your baking more sustainable.
Troubleshooting Common Issues
Dough too sticky? Chill it longer or add a tablespoon of flour at a time until manageable.
Crust shrinking during baking? Avoid stretching the dough when placing it in the pan and let it rest before baking.
