Preheat oven to 350°F. Line a 9-inch pie pan with the refrigerated pie crust, crimp the edges as desired, and prick the bottom with a fork.

Line the pie crust with parchment paper or foil and fill with pie weights or dry beans. Bake on the middle rack for 10 to 12 minutes. Remove the weights and parchment, then bake an additional 5 to 7 minutes until the bottom is dry and lightly golden. Remove from oven and let cool slightly.
