In a food processor or large mixing bowl, combine the flour, sugar, and salt. Pulse or whisk to blend.
Add diced cold butter. Pulse a few times until the mixture resembles coarse crumbs with some pea-sized pieces. If using a pastry cutter, work it in gently.
Drizzle in 7 tablespoons of ice water. Pulse or stir until the dough starts to clump. Add more water by the teaspoon if needed.
Turn the mixture onto a surface and gather into a ball. Divide in half, shape into disks, and wrap in plastic wrap. Chill for at least 1 hour.
After chilling, dust your surface with flour and roll one disk into a 12-inch circle. Transfer to your pie dish, press gently, and trim or fold the edges.
For pies that use an unbaked crust—such as pumpkin, apple, or chicken pot pie—simply add the filling directly to the raw crust and bake according to the recipe instructions. To make a blind-baked (pre-baked) pie crust, you’ll need pie weights, dried beans, or uncooked rice to prevent the crust from shrinking as it bakes. Line the unbaked crust with a large piece of parchment paper, then fill it with pie weights or 1–2 cups of beans or rice. Bake at 375°F for 15–20 minutes. Carefully lift out the parchment paper and weights, prick the bottom of the crust with a fork, and return it to the oven for another 10–15 minutes, or until lightly golden. Let the crust cool completely before adding the filling.
