Crustless Quiche Lorraine, a low-carb version of the classic dish, is made with a rich egg custard, bacon, onions and gruyere cheese. You will never miss the crust.
Classic Quiche Lorraine, which originated in the Lorraine region of France with heavy German influence, is ubiquitous among cafes throughout France. Traditional French quiche does not contain cheese, is baked in a brioche type of pie crust and is usually served at room temperature or slightly warm. Quiche Lorraine grew in popularity in mid-20th century and one of the most popular modern versions includes Gruyere cheese.
In recent years, the desire to find delicious low-carb and keto-friendly dishes led to the development of crustless Quiche Lorraine recipes like this one. Crustless Quiche Lorraine is surprisingly simple to make. In fact, the recipe is exactly the same as the version with crust, just no crust. Simply spray the inside of a glass pie pan with cooking spray and build the Quiche Lorraine directly in the pie pan. The egg custard will actually form a very thin golden brown crust on its own that does not stick to the pan. There are no specials tools or techniques. That's all there is to it.
- Heavy cream
- Gruyere cheese
- Kosher salt
- Black pepper
See recipe card for quantities.
Add a layer of sautéed onion and cooked, crumbled bacon to a prepared glass pie pan.
Place a layer of cheese on top of the onion and bacon.
Add one more layer of onion, bacon and cheese.
In a large bowl, mix the eggs, cream, nutmeg, salt and pepper. Pour egg mixture over the onion, bacon and cheese and bake until puffy and golden brown.
Quiche is very versatile and can be easily modified to accommodate what you have on hand. Some variations to try are:
- Mushrooms - Try adding ½ cup of sautéed mushrooms to the layers of onion and bacon.
- Pancetta - Rather than bacon, try using thick cut pancetta. Just cut into ¼" pieces and fry them first.
- Swiss Cheese - Gruyere cheese can be hard to find. Swiss cheese is a wonderful substitute.
A glass pie pan works better for this recipe than a metal pie pan because a glass pie pan provides more even heat distribution and food is less prone to sticking.
Reheat pieces of Quiche Lorraine in an oven at 275°F for about 8 minutes or until warm inside.
Make sure the center of the Quiche Lorraine is "set" before taking it out of the oven. Using oven mitts, jiggle the pie dish side to side. If the center wiggles, it needs a few more minutes.
