In a large bowl, combine flour, salt, and sugar. Cover and let chill in the fridge or freezer until bowl is cold, about 5 minutes.
Using a pastry blender (or two forks), cut cold butter into cold flour until mixture resembles coarse, pebbled sand. Add ice water and fold to combine. Dough will be shaggy.
Dump dough onto a lightly floured work surface and knead until mixture comes together. Pat dough to a thickness of about 1/2-inch. Wrap in plastic wrap and let chill in the fridge for at least 1 hour (overnight is best).
Allow chilled dough to sit at room temperature for 5 minutes before rolling. Roll dough on a lightly floured work surface to about 11-inch in diameter and about 1/8-inch in thickness. Place pie plate upside down over the rolled dough to ensure it is the correct size.
Transfer dough to pie plate and firmly press into the bottom and sides of plate. Trim excess dough leaving about 1/2-inch overhang all around. Fold overhang into the pie and decorate the edges as desired. Let chill in the fridge for 10-15 minutes.
Preheat oven to 400oF. Line pie with parchment paper and fill with pie weights (i.e. dried beans). Bake for 15 minutes. Remove pie weights and bake for another 3 minutes. Allow pie crust to cool while you prepare filling.
