Press pie crust into a 9-inch pie dish, trimming and fluting edges as desired. Refrigerate crust for at least 20 minutes to prevent shrinkage. Preheat oven to 375°F. Line crust with parchment and fill with pie weights or dried beans. Par-bake for 15 minutes, remove weights and parchment, then bake 5 more minutes until lightly golden. Brush warm crust bottom with beaten egg white to seal.

Bake at 375°F for 50 to 60 minutes, tenting with foil after 30 minutes if crust browns too quickly. Bake until filling bubbles and apples are tender when pierced with a skewer. Cool pie for at least 2 hours before slicing to allow filling to set.
