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 this 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 every year, and this crustless quiche would definitely be a fun Christmas tradition 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 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.

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 dish, it’s the step of mixing a generous amount of 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. I hope you try it!

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.
