Step 1

Pulse flour, cheese, 1/2 teaspoon salt, and 1/4 teaspoon pepper in food processor until combined. Add butter and shortening. Pulse until butter and shortening are pea size pieces, about 5 times. Drizzle in buttermilk processing until dough begins to just come together. Gather and lightly knead dough into a ball on a large piece of plastic wrap; flatten into disk and wrap tightly. Chill at least 2 hours or up to 2 days.

Step 2

Preheat oven to 400F. Roll dough on a floured surface into a 15 to 16-inch circle about 1/3 inch thick. Transfer to a 9-inch deep dish pie plate. Trim edges leaving a 1 inch overhang. Fold edges under and crimp. Freeze dough at least 20 minutes.

Step 3

Line pie crust with parchment paper and fill with pie weights or dried beans. Bake at 400F 20 minutes. Remove parchment and weights and bake until edges are golden and bottom of crust is set, about 8 more minutes. Cool completely about 30 minutes.
