Arrange pie crust in a 9-inch pie plate; press a double layer of aluminum foil into crust.
Bake at 450 degrees for 8 minutes; remove aluminum foil and bake an additional 4 to 5 minutes, until crust is set. Cool on a wire rack.
Sauté onion in one tablespoon reserved drippings until tender; drain. Spoon bacon and onion evenly into baked crust. In a large bowl, whisk together eggs, half-and-half and seasonings; add cheese and whisk to combine.
Pour into crust; set pie plate on a baking sheet. Bake at 450 degrees for 35 to 40 minutes until quiche is golden, puffed and a knife inserted in center comes out clean.
If necessary, cover edges of crust with foil to prevent burning. Remove from oven; let stand 15 minutes before serving.
