Prepare pie crust. If choosing to use a frozen crust, be sure it is completely thawed per package instructions. If you are using a refrigerated pie crust/dough prepare in a 9-inch glass or metal pie pan and set aside. Follow any package instructions for pre-cooking or pre-baking.

Cook bacon slices in a medium pan on medium-high heat until crisp. Pat bacon dry with a paper towel and crumble. Set aside.

In a large bowl, combine eggs, heavy cream and milk and mix well until thoroughly blended.

Combine shredded cheese, chopped onion, bacon, salt and pepper in a bowl. Add to egg mixture and mix well.

Pour egg mixture into pie crust and bake for 40-50 minutes or until a toothpick inserted in the middle comes out clean.
