Cut cold butter into ½-inch cubes and refrigerate. Fill a small bowl with ice water and measure 8 tablespoons, keeping it chilled.
In a large mixing bowl, whisk together flour, sugar, and salt until well combined.
Add cold butter cubes to flour mixture. Using a pastry cutter or two forks, cut butter into flour until mixture resembles coarse crumbs with pea-sized to lima bean-sized butter pieces.
Drizzle 6 tablespoons ice water over mixture. Gently mix with a fork until dough begins to clump together. Add remaining water 1 tablespoon at a time only if needed. Dough should hold together when squeezed but look slightly shaggy.
Turn dough onto a clean work surface and gather into a mound. Divide into two equal portions and shape each into a flat disk about 1 inch thick.
Wrap each disk tightly in plastic wrap. Refrigerate for at least 1 hour or up to 3 days. For best results, chill for 2 hours before rolling.
Remove one disk from refrigerator and let sit for 5 minutes. Lightly flour work surface and rolling pin. Roll from center outward, rotating dough a quarter turn after each roll, until you have a 12-inch circle about ⅛ inch thick.
Roll dough loosely around rolling pin, then unroll over pie dish. Gently press dough into bottom and sides without stretching. For single-crust pie, trim overhang to 1 inch, fold under, and crimp decoratively.
Place prepared pie crust in refrigerator for at least 30 minutes before filling and baking to prevent shrinkage.
