Cheesy Crustless Quiche Lorraine finished dish with one serving on plate

Cheesy Crustless Quiche Lorraine is my Friday’s Favorites pick for this week, and this is a recipe I think would be perfect any time you’re making a special breakfast. I learned to love Quiche Lorraine when I worked part-time during college at a charming (and long-gone) Salt Lake City French restaurant called Le Parisien.

You may have had this traditional French quiche with a flaky pastry crust filled with custard that contains bacon, onions, and cheese. Of course that’s a tasty dish, but my crustless Quiche Lorraine is a low-carb version that I think is just as delicious as the original.

And in case anyone is wondering how this crustless quiche recipe differs from one of my usual low-carb breakfast casseroles other than the obvious use of a round pie dish, it’s the step of mixing half and half into the eggs for more of a custard consistency. And of course a lot of the good flavor in this crustless quiche comes from using bacon, grated Swiss cheese, Mozzarella, and Parmesan for lots of rich flavor.

What ingredients do you need for this recipe?

(This is only a list of ingredients; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  • bacon
  • green onions
  • grated Swiss cheese
  • grated Mozzarella cheese
  • coarsely grated Parmesan cheese
  • fresh ground black pepper to taste
  • Spike Seasoning (affiliate link) or use another seasoning blend
  • cayenne pepper (affiliate link), optional
  • eggs
  • half and half

Can you make the Crustless Quiche Lorraine lower in fat?

The use of half-and-half, bacon, and three types of cheese make crustless Quiche Lorraine a delicious dish. But if you’re not up for that much fat you can definitely make a delicious version using milk, lower-fat cheese, and/or turkey bacon if you prefer.

Why is it called Quiche Lorraine?

The word quiche comes from the German word for cake, and Lorraine is the name of a region in France where this dish originated.

Does Quiche Lorraine always contain cheese?

You may be surprised to hear that originally Quiche Lorraine was made with just eggs, cream, and bacon but some years ago people started adding cheese. Now you can see lots of recipes for a cheesy Quiche Lorraine like this one.

How to make Cheesy Crustless Quiche Lorraine:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. I used pre-cooked bacon that has a lot of the fat already cooked out and then cooked it in the microwave and blotted off more fat before I crumbled it.
  2. Put the crumbled bacon and sliced green onions into a 9-10″ glass pie dish and top with the cheeses.
  3. Sprinkle with Spike Seasoning (affiliate link) or another seasoning blend that’s good with eggs, black pepper, anda little cayenne pepper (affiliate link).
  4. Beat the eggs, then whisk in the half and half. (Use 6 eggs for a thinner richer quiche, or use 8 eggs for a thicker quiche.)
  5. Pour egg mixture over the other ingredients and gently stir.
  6. Bake in a pre-heated 350F/180C oven for 45-50 minutes. It will puff up while it cools, but it settles down as it cools a bit.
  7. Serve hot and enjoy, garnished with some diagonally sliced green onion if you’d like!

Cheesy Crustless Quiche Lorraine is my version of this classic French quiche that's low-carb, Keto, and gluten-free.


  • 8 slices bacon (see notes)
  • 1/2 cup sliced green onions (white part preferred)
  • 1 1/2 cups grated Swiss cheese
  • 1/2 cup grated Mozzarella cheese
  • 1/4 cup coarsely grated Parmesan cheese
  • fresh ground black pepper to taste
  • 1/4 tsp. Spike Seasoning, see notes (or use another seasoning blend that's good with eggs)
  • 1/8 tsp. Cayenne Pepper, optional (see notes)
  • 8 eggs (see notes
  • 3/4 cup half and half (see notes)
  • 2 T diagonally sliced green onion for garnish (green part preferred)


  1. Preheat oven to 350F/180C. Spray a 9-10 inch pie dish with nonstick spray.
  2. Cook bacon using your preferred method until it's very crisp; then blot away as much fat as you can and crumble the bacon. (I used Costco pre-cooked bacon which I cooked in the microwave for 1 minute and then blotted the fat.)
  3. Slice green onions and grate cheese if you need to.
  4. In the pie dish layer the bacon, green onions, Swiss cheese, Mozzarella cheese, and Parmesan cheese. Season with ground pepper, Spike Seasoning, and Cayenne Pepper.
  5. Beat the eggs until yolks and whites are completely combined, then whisk in the half and half.
  6. Pour the egg mixture over the other ingredients; then use a fork to gently stir so all ingredients are combined.
  7. Bake 45 minutes or until the center is firm and the top is browned to your liking. The quiche will puff up as it cooks, but when it cools slightly it will sink down into the dense custardy consistency you see in these photos.
  8. Serve warm, garnished with green onions if desired.
  9. This will keep in the refrigerator for several days and can be reheated in the microwave.


I originally made this with six eggs for a thinner richer quiche with a more custardy texture, but now I'd prefer to use eight eggs. You could use turkey bacon or chopped Canadian bacon for this recipe if you're wanting lower fat. Use heavy cream or milk instead of half and half if you prefer.

Spike Seasoning (affiliate link) is one of my favorite seasonings for eggs, but any blend that's good with eggs will work. I love a touch of Cayenne Pepper (affiliate link) in this, but it's definitely optional.

This recipe created by Kalyn and Kara and inspired by Crustless Three-Cheese Tomato Basil Quiche and memories of working at Le Parisien Restaurant.
