You may make a homemade crust or use premade frozen pie crust.
Homemade or frozen crust?
Roll into a 1-inch disc. Wrap in plastic wrap and refrigerate for 2 hours to overnight. Then, on a floured surface, roll the disc to ⅛ inch thickness and place in a 9-inch pie pan.
Prepare the dough
Poke holes across the bottom and up the sides of the crust. Place parchment paper on top of the crust and partially fill with pie weights or beans. Bake for 15 minutes.
Cook the bacon & shallots
Whisk the egg mixture
Add half of the cheese, bacon and shallots, your egg mixture, and more cheese. Bake.
Serve hot, at room temperature, or chilled.
