Quiche Lorraine

Bacon, Swiss cheese, and caramelized onions are the stars in this luscious recipe for Quiche Lorraine.

What is Quiche Lorraine?

Quiche Lorraine is simply a variety of quiche that originated in the region of Lorraine, France. More specifically, it is a French egg custard baked with bacon, onions, and Swiss cheese in a pie crust.

And it is the epitome of quiche recipes! I mean, who can resist bacon?! In fact, it was the first popular quiche recipe here in America--again, bacon!

From the flaky, buttery pie crust to the rich, cheesy custard, to the tender, slightly sweet onions, to the crispy, savory bacon, Quiche Lorraine has it all.

It is creamy, cheesy, rich, and downright divine. Even people who say quiche isn't their thing may find it hard to resist a slice of this quiche 😉

Notes on Ingredients

• Pie Crust: Use a homemade pie crust, refrigerated pie dough sheets, or a 9-inch deep-dish frozen pie crust.
• Bacon: For Quiche Lorraine, I do recommend using pork bacon over turkey bacon for the best flavor, and you need the rendered bacon fat to use for sauteeing the onions. I prefer using thick-cut, cubed bacon, for nice hearty pieces of bacon throughout the quiche. That said, any thick-cut pork bacon works well.
• Onions: Use Vidalia or sweet onions, rather than yellow or red onions, for the best sweet, mellow flavor.
• Cream and Milk: Using both cream and milk will keep the custard creamy yet light. Use any fat percentage for the milk you have on hand.
• Cheese: Use a combination of freshly grated Parmesan and use either Gruyere or Baby Swiss for the best taste.
• Nutmeg: A bit of grated whole nutmeg adds warmth and complexity to the egg custard.

How to Make Quiche Lorraine

Step One: Prebake Pie Crust

In order to prevent the crust becoming soggy and to ensure the pie crust cooks through, the crust needs to be prebaked.

• Roll out the prepared, chilled homemade or refrigerated pie dough into ¼ inch thick circle on a lightly floured surface and then carefully transfer the pie crust a 9-inch deep dish pie pan.
• Trim or flute the pie edges to form a crust.
• Place pie dough into the freezer for 15 minutes or in the refrigerator for 1 hour.
• Remove the pie crust from the freezer or refrigerator and prebake.
• Line the crust with parchment paper and fill with dried beans or pie weights. Bake for 15 minutes. Remove the pie weights and continue baking until the bottom crust is golden, 5 to 10 minutes more. Let cool slightly.

Recipe Note: For a frozen pie crust, there is no need to use pie weights or dried beans, simply bake the pie crust from frozen for 10 minutes and then cool slightly.

Step Two: Prepare Quiche

• In a medium skillet, cook the bacon over medium heat until crisp. Remove it from the skillet and place it onto a paper-towel-lined plate.

• Pour off all but one tablespoon of the fat remaining in the skillet. That grease will help to flavor the onions much more than using olive oil. Add the onion to the rendered bacon grease and cook until the onion is caramelized, stirring often.

• In a medium mixing bowl, whisk together the eggs, milk, cream, nutmeg, salt, and pepper until well combined.

• To the prepared pie crust, add the cooked bacon and onion.
• Sprinkle the onion and bacon evenly with the cheese.
• Pour the egg mixture over the pie crust. Gently tap on the counter to remove any air bubbles.

• Bake quiche at 375 degrees for 25-30 minutes or until the eggs are set around the edges and the center is just slightly wobbly. After 20 minutes, check your quiche to determine if the crust is browning too much. At this point, you can use pie shield or foil to shield your crust from further browning if needed.
• After baking, remove the quiche from the oven and allow to cool for 10-15 minutes before serving.
