You will need 8-inch (20cm) or 9-inch Pie Dish. For a 9.5-inch or 10-inch Pie dish make the pecan pie filling x2 times.
Combine flour, sugar, and salt in a food processor or mixing bowl. Add cold, cubed butter in two batches and pulse until the mixture forms pea-sized crumbs.
Gradually add iced water, one tablespoon at a time, until the dough just comes together. Avoid over-mixing to keep the crust tender.
Shape the dough into a ball, wrap it tightly, and refrigerate for 2 hours to 2 days. Beyond this time period the dough will start to turn grey in the fridge. Keeping it cold makes it easier to roll and bake.
Lightly flour a clean surface and rolling pin. Flatten the dough into a disc and roll from the center outward, turning frequently, to about 1/8 inch or 3mm thick. Make sure it’s large enough to cover the pie dish with a 2–3 inch overhang.
Roll the dough onto the pin and carefully unroll it over the pie dish. Press gently into the edges without stretching the dough. Trim excess with a pair of scissors, leaving a 1.5-inch overhang, then fold under and crimp the edges.
Freeze the crust for 30 minutes or for 2 days (if making ahead) before baking. Dock the dough all over with a fork to prevent puffing. Line with parchment paper and fill half way with pie weights, dried beans, or rice. This will prevent the pie crust from shrinking.
Blind bake at 350°F (175°C) for 25–30 minutes until lightly golden. Remove the weights and bake for another 5–7 minutes to dry and bake the base. The crust should be firm, golden, and ready for the pecan pie filling.
Roll and freeze any leftover pie dough for up to 3 months.
