1. Pre-bake the crust: Preheat your oven to 350°F (175°C).
If you are using a store-bought pie shell, follow the directions on the package for pre-baking, or pre-bake it in the oven for about 8 to 10 minutes (a little longer for a frozen pie shell), until lightly browned.
If you are using a homemade crust, freeze the crust first, then press a sheet of aluminum foil into the crust to keep the sides of the pie crust from falling down as it cooks. Fill the pie with pie weights such as dry beans or rice to help hold the foil in place.
Pre-bake the homemade crust for 15 minutes, then remove the foil, use the tines of a fork to poke a few small holes in the bottom of the crust (for venting), and bake for 10 more minutes.
