This easy crustless quiche recipe was inspired by my summer herb obsession… fresh basil! Keto crustless quiche Caprese is made without crust, and gets its inspiration from classic Caprese salad and avocado Caprese salad – one of my favorite uses for fresh basil. Think “the brunch take” on summer’s best salad!

You can turn this into a regular keto quiche with a crust as well, but if you want the fastest, easiest way to make a quiche, crustless is the way to go. Like my crustless zucchini quiche, it packs so much summery flavor into every bite.

This easy keto crustless quiche recipe was originally published on June 30, 2016 and updated in July 2020 to add in helpful tips and step-by-step photos. Here’s one of the original photos if you’re curious!

I first made this quiche when one of my first basil plants was growing out of control and I needed to use up a lot of the basil quickly. But, the method I use here makes a good base for any low carb quiche recipe, even if you want to change up the fillings.

For me, this one is definitely toward the top of the list for the bestcrustless quiche recipe!

How To Make A Crustless Quiche

The instructions here are for a quiche caprese, but you can use the same method for a basic crustless quiche recipe, no matter what fillings you want to use. Check the FAQ’s further below for how to make crustless quiche using a variety of different fillings.

  • Make caprese filling. Combine tomatoes, basil, minced garlic, and mozzarella pieces in a bowl. Transfer mixture to the bottom of a round glass pan.

TIP: If you can tolerate a little natural sugar, you can even lightly drizzle balsamic vinegar or glaze on top. That part is totally optional, though.

Crustless Quiche Recipe FAQs

How do you make crustless quiche using different fillings?

While I opted for a Caprese version, this is actually an excellent basic crustless quiche recipe that you can dress up any way you like.

The method is very similar to my vegetable frittata recipe, we just bake crustless quiche in the oven only:

  1. Pre-cook vegetables IF they need to be cooked. One of the reasons I picked quiche Caprese is that it’s not necessary to cook the fillings. Tomatoes and basil hold up pretty well uncooked. But with most vegetables, you’ll want to cook them before adding to the pan.
  2. Whisk the eggs, milk, salt and pepper. This is your base.
  3. Bake. If you want cheese on top of your frittata, it’s best to add that halfway or toward the end of cooking, to avoid burning it.

If you need ideas for crustless quiche fillings, these all work great:

  • Bacon or sausage
  • Keto vegetables – such as zucchini, bell peppers, broccoli, spinach, etc. As mentioned above, pre-cook these by sauteing or steaming first.
  • Cheese – You can use hard cheeses like gruyere, cheddar, or gouda, or soft ones like feta, fresh mozzarella, or goat cheese

What is the difference between a frittata and a quiche?

Here are the main differences between a crustless quiche and a frittata:

  1. The cooking method. Crustless quiche recipes are simply baked in the oven, while a frittata starts on the stove top and moves to the oven later.
  2. The amount of milk. Quiche has more milk than a frittata does.
  3. The type of pan. Quiche with or without crust is made in a pie pan, while a frittata typically uses a cast iron pan so that it can go from stove top to oven.

Can you make it with a crust?

Yes, you can. Try almond flour pie crust or coconut flour pie crust.

Pre-bake the crust first, then follow the rest of the recipe. You’ll need to cover the crust edges with foil or a pie crust shield to prevent burning it.

Read my guide for the best keto quiche with crust here.

Is crustless quiche keto?

Yes, this is keto friendly crustless quiche, but you don’t have to be keto to enjoy it. Most crustless quiche recipes are naturally keto because they are low in carbs, but they are delicious to serve for anyone.

Each serving (1/6 of the quiche) has just 2.9 grams net carbs. It makes a great breakfast, brunch or even lunch.

Can you make this crustless quiche recipe dairy-free?

Yes, you can easily make this recipe dairy-free! Simply omit the mozzarella or use your favorite dairy-free cheese alternative.

Can you make it nut-free?

Yes. Use heavy cream or half & half instead of the almond milk. Coconut milk beverage (the thin kind in a carton, not the thick kind in a can!) works fine as well.

Easy Crustless Quiche Storage Instructions

Can you make it ahead?

Yes, you can make this crustless caprese quiche ahead of time. My easy crustless keto quiche makes a great meal prep breakfast or lunch option as it can be made ahead and reheated when you’re ready to eat it.

How to store crustless quiche

Store this crustless vegetable quiche in the refrigerator for 3-4 days.

Can you freeze crustless egg quiche?

Yes, you can freeze crustless quiche for 2-3 months.

Let thaw in the refrigerator for a few hours before reheating in a 350 degree F oven. I don’t recommend reheating in the microwave, which can make it soggy.

How to reheat quiche

Crustless quiche recipes can be reheated in the oven at 350 degrees F, until hot.
