The secret to an exceptionally flaky pie crust that professional bakers don’t often share is sourdough starter discard. This game-changing ingredient transforms ordinary pie crust into a tender, complex pastry with subtle tangy notes.
The natural acids in sourdough not only create an incredibly flaky texture but also make the crust more digestible than traditional versions. Whether you’re a seasoned baker looking to elevate your pie game or simply trying to use up sourdough starter discard, this recipe promises a crust that’s both traditional and innovative.
Why Sourdough Makes a Better Crust
The magic of sourdough lies in its fermentation process. The natural fermentation breaks down gluten proteins and makes nutrients more bioavailable while adding a subtle tangy complexity that enhances both sweet and savory fillings.
This fermentation process also creates a more digestible crust that’s perfect for those who find traditional pastries heavy.

Tips for Perfect Flakiness
The secret to achieving the flakiest sourdough pie crust lies in technique and temperature. Keep all ingredients cold, especially the butter and sourdough starter.
Work the dough minimally to maintain butter chunks, which create steam pockets during baking, resulting in those desirable flaky layers. Chilling the dough between steps is crucial for maintaining structure.

This versatile sourdough crust shines in both sweet and savory creations:
Sweet Applications:
- Fruit pies (apple, cherry, peach, blueberry)
- Pumpkin and custard pies
- Galettes with seasonal fruits
- Hand pies with jam fillings
- Crostatas with mixed berries
- Mini tarts with cream fillings
- Rustic fruit turnovers
Savory Options:
- Quiche with spinach and feta
- Chicken or turkey pot pie
- Tomato pie
- Savory vegetable galettes
- Meat hand pies
- Mushroom tart
- Onion and cheese tart
