This is my absolute favorite quiche recipe! It's creamy, easy and delicious, and just loaded with savory flavor. Even better, with consideration to your caloric/macronutrient goals, not having a crust allows you to enjoy even more of it!

This recipe comes from my new book, Keto Comfort Foods: 100 Keto-Friendly Recipes for Your Comfort Food Favorites! It's a great resource for anyone looking for low carb replacements to some of your favorite foods. There’s even an entire chapter just for pizza!

Is this a breakfast quiche?

This Quiche Lorraine can be eaten any time of day, but it does make an excellent keto breakfast. It contains the traditional ingredients of cream, eggs, onion, swiss cheese, and bacon. This combination is mind-blowingly good, and a definite must-try if you're looking to switch up your routine.

Also, if you're not ready to fully embrace the crustless quiche by ditching the crust completely, you can search some really great keto crust options, like this pepperoni pizza quiche with a crust from Ruled.Me!

This breakfast casserole is so full of savory flavor that you won't even miss the usual crust. The eggs are fluffier and creamier than you would expect with a frittata. With only a few simple ingredients, this filling dish is the perfect meal to prep the night before and pop in the oven when you get up in the morning.

Prep Time 15 minutes
Cook Time 20 minutes
Total Time 35 minutes


  • 2 tablespoons salted butter
  • ½ medium yellow onion, peeled and diced
  • 1 clove garlic, peeled and finely minced
  • 8 slices bacon
  • 6 large eggs
  • ¾ cup heavy whipping cream
  • ½ cup shredded Swiss cheese
  • ½ cup shredded Monterey Jack cheese


  1. Preheat the oven to 375 degrees Fahrenheit.
  2. In a medium skillet over medium heat, melt butter, then add onion and saute until it begins to caramelize and become fragrant (about 15 minutes). Add garlic and saute for 30 seconds. Transfer onion and garlic to a large mixing bowl.
  3. Replace the pan over the heat and add bacon. Fry until crispy, about 10-12 minutes. Place bacon on paper towels to absorb the excess grease.
  4. Crack open eggs into the bowl with the onion and garlic, then pour in heavy whipping cream. Whisk together until fully combined.
  5. Crumble bacon into the bowl, then add the cheeses and mix. Pour the mixture into a round 9-inch pie dish or similarly sized pan. Bake for 20 minutes. When done, the egg mixture should be set, but not overly firm. Let cool for 15 minutes before slicing and serving.

This is a fabulous base recipe. I've made it also with spinach, broccoli and/or seafood. The only limit is your imagination. Thank you for sharing!

Love this recipe, I add sautéed mushrooms , but also ,beat eggs slightly before adding to bowl and beat whip cream till thickish not peaks and then fold it in mixed Ingredients , makes it even lighter and fluffier. YUM.

This recipe was creamy and delicious. Don't even miss the crust. We have 9 chickens, so yummy way to use up our yard eggs too!!

Delicious! I substituted the onion for shallots just because of personal preference.

The directions don’t state whether or not the pie pan should be greased, and I’ve had issues with other crustless quiches sticking to my pan, so I used butter for mine, just to be safe (I wasn’t sure if cooking oil would impact the texture of the quiche). I had to cook it for about 10 minutes longer than the recipe stated, but it came out perfectly!

I had mine for lunch with a simple spinach salad and the rest will serve as breakfasts for the week. Great recipe and I will definitely make this again!

I added a handful of sliced mushrooms fried in a bit of butter. Really a nice surprise to the taste. Baked 5 minutes longer and turned off oven and let sit in there for 10 min. We all really liked it - could easily have made 2!
