Cheesy Crustless Quiche Lorraine

Cheesy Crustless Quiche Lorraine is my low-carb and Keto version of this classic French quiche that’s also gluten-free. And I think this is perfect to make during the holidays, and my Quiche Lorraine recipe without the crust uses ingredients you might keep in the house!

I think Cheesy Crustless Quiche Lorraine would be perfect any time you want breakfast for a special occasion. My sister Val has the tradition of making quiche for Christmas morning, and this crustless quiche would definitely be a fun Christmas breakfast for families who are watching carbs!

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 that famous and 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 I think my crustless Quiche Lorraine is just as delicious.

And in case anyone is wondering how this crustless quiche recipe differs from my usual low-carb breakfast casseroles other than the obvious use of a round dish, it’s the step of mixing a generous amount of half and half into the eggs to create 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 rich flavor. I hope you try it!

What ingredients do you need for this recipe?

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 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 Cheesy Crustless Quiche Lorraine hot and enjoy, garnished with some diagonally sliced green onion if you’d like!

Cheesy Crustless Quiche Lorraine

Prep Time 15 minutes

Cook Time 45 minutes

Total Time 1 hour

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

Ingredients

• 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)

Instructions

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 crustless Quiche Lorraine will keep in the refrigerator for several days and can be reheated in the microwave.

Notes

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.
