Place the frozen pie crust on a baking sheet and bake for about 10 minutes, or until it turns a light golden brown. Prebaking the pie crust helps prevent it from becoming soggy.
Whisk together half and half and cornstarch until fully blended. Add the lightly beaten eggs and whisk until well combined.
Leaving the pie crust on the baking sheet, start layering the cheeses, onions, and the bacon.
Take your egg mixture and pour over the layers in the pie crust.
Place the quiche in the preheated oven and bake for approximately 45 minutes. Every oven bakes differently. So it is important to watch what is baking. I always check my quiche at 30 minutes. If the crust or top of the quiche looks like it is browning too quickly, drape a piece of tin foil over the pie. This will reflect heat and slow down the browning process. To check if the quiche is done, insert a knife in the center. If it comes out clean, it is done. If the center jiggles and doesn't look set, continue to cook it for a bit longer.
Remove quiche from the oven and allow it to cool for 10 minutes before serving. Another great thing about a quiche is it is delicious served watm or at room temperature making it a great option for entertaining.
