Par-bake pie crust: Preheat oven to 350 degrees F. Place unbaked pie shell in pie pan. Place a piece of parchment on top, and add some pie weights or a cup of dry rice or beans. Bake pie crust for 8 minutes. Remove parchment with pie weights. (Pie weights keep the crust from shrinking as it bakes).

Cook Bacon in a skillet over medium low heat, turning often. Remove to a plate and chop. Remove most of the grease from the pan and add onion to the pan and sauté for 2-3 minutes minutes.

Assemble: Sprinkle cheddar and Swiss cheeses around the bottom of the partially baked pie crust. Add bacon and onion on top. Mix eggs, cream, milk and spices in a bowl. Gently stir while pouring over crust to evenly distribute all of the spices. Sprinkle shredded parmesan cheese on top.

Bake at 350 degrees for 45 minutes - 1 hour, depending on your oven, until the center of the quiche is just set. If you notice the pie crust is browning too much you can place a piece of foil over it while cooking. (I don't usually need to do this with a homemade pie crust).

Remove from oven and cool for at least 15 minutes before slicing. Refrigerate leftovers.
