- Yield: 1 9-inch pie crust 1x
Description

Ingredients
Pie Crust Ingredients
- 1 1/4 cups all-purpose flour
- 1/2 cup cold unsalted butter, cubed
- 1/2 cup sourdough discard
- 1/2 teaspoon salt
- 2 to 4 tablespoons ice water
Instructions
- Combine Dry Ingredients: In a large bowl, whisk together the all-purpose flour and salt to evenly distribute the salt throughout the flour.
- Cut in Butter: Add the cold, cubed unsalted butter to the flour mixture. Use a pastry cutter, fork, or your fingertips to cut the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces.
- Add Sourdough Discard: Stir in the sourdough discard using a fork or your hands until the dough just begins to come together. Avoid overmixing to maintain flakiness.
- Add Ice Water Gradually: Slowly add ice cold water one tablespoon at a time, gently mixing after each addition until the dough holds together when pressed. Depending on humidity and flour, you may need 2 to 4 tablespoons.
- Shape and Chill Dough: Gather the dough into a ball and flatten it gently into a disk. Wrap it tightly in plastic wrap and refrigerate for at least 1 hour to relax the gluten and keep the butter cold.
- Roll Out Dough: On a lightly floured surface, roll the chilled dough into a circle about 1/8-inch thick, ensuring an even thickness throughout to promote even baking.
- Transfer to Pie Dish: Carefully transfer the rolled dough to your pie dish. Trim any excess dough around the edges and crimp the edges decoratively to seal.
- Chill Before Baking: Return the pie crust to the refrigerator to chill again, which helps prevent shrinking during baking. If your recipe calls for blind baking, prepare with pie weights.
- Bake the Crust: Bake according to your pie filling’s instructions or blind bake at 375°F (190°C) for 15 to 20 minutes until the crust is golden and cooked through.
- Cool before Filling or Serving: Allow the crust to cool completely before adding filling or serving to ensure it holds its shape and texture.
Notes
- Use cold butter and ice water for maximum flakiness in the crust.
- Resting the dough well in the refrigerator prevents shrinking and helps relax the gluten.
- If blind baking, use pie weights or dried beans to keep the crust from puffing up.
- This crust works well for both sweet and savory pies.
- Store any unused dough tightly wrapped in the fridge for up to 2 days or freeze for up to 1 month.
