Combine the flour, salt, and sugar in a food processor by pulsing a couple of times.
Add ⅔ of the butter cubes and pulse until the butter is fully coated in flour and is in pea-sized pieces.
Place the mixture into a large mixing bowl and add the rest of the butter. Work the dough with your hands until all the butter is coated in flour and there are still large chunks of butter visible.
Add cold water 2 tablespoons at a time, mixing with a fork between each addition. Once all the water is in, the dough should look very crumbly but will hold together if you squeeze some in your hand. If the dough crumbles in your hand after squeezing, add extra water (1 tablespoon at a time) until the right texture is achieved.
Place the dough on a piece of plastic wrap and shape it into a disc. Wrap it tightly and place it in the refrigerator for 1 hour.
Roll out your chilled dough on a floured surface to fit your 9” (23cm) pie pan. Transfer the dough into the pan. Trim any excess dough if needed, leaving about an inch overhang.
Crimp the edges and prick the bottom using a fork. Place the unbaked crust into the freezer while the oven is preheating to 425F (220C).
Line the crust with parchment paper or aluminum foil, then fill it with pie weights, dried beans, or rice. Place the crust into the oven, then reduce the heat to 375F (195C). Bake the crust for 18-20 minutes, until the edges start to turn golden.
Remove the parchment paper or aluminum foil and weights, and bake for an additional 15-20 minutes until the crust is fully baked and golden brown.
Allow the crust to cool completely before adding your filling.
