Step 1

Preheat oven to 425°F. Line a 9-inch pie plate with store-bought pie crust and crimp the edges.

Step 2

In a medium bowl, whisk milk, eggs, salt, and pepper. Set aside.

Step 3

Layer cooked, crumbled bacon, Gruyère and Parmesan cheeses, chopped asparagus, and scallions in the crust-lined pie plate. Pour the egg mixture over the top.

Step 4

Bake 15 minutes in the oven at 425 degrees. Reduce the oven temperature to 325 degrees and continue to bake for another 20 to 25 minutes, or until a knife inserted in the middle comes out clean. Cool 10 minutes before cutting into wedges.
