Crustless Vegetable Quiche Recipe

In this post I’ll be sharing an easy low carb Crustless Vegetable Quiche Recipe. It is so delicious!

A crustless vegetable quiche is a great way to cut some of the carbs from your diet. It’s an easy to prepare and healthy option for breakfast or brunch.

Leftovers, if you have any, of this veggie quiche re-heat nicely the next day too.

Is a crustless quiche just a baked omelet? No. I know many use the term baked omelet but there is truly no such thing. Omelets are prepared on the stove top.

What is the difference between a frittata and crustless quiche? The method of preparation mostly. A frittata starts out on the stove top and is finished in the oven. The quiche has its ingredients added to the egg custard and baked.

Quite frankly, who really cares what you call it? It’s delicious and that’s all that you need to know. HaHa! I’m teasing but you can call it whatever you want.

This recipe has some delicious veggies but if you wanted to add meat then you certainly can.

If you decide you’d like to add some extra protein then consider adding half a cup of diced ham, chopped bacon, or cooked sausage.

To get things started with my meatless version, I sauté the vegetables slightly to soften them up.

At the last minute throw your spinach into the skillet and combine with the softened vegetables.

Next comes whipping up the custard part of the quiche then stirring in the sautéed vegetables along with some cheese. 

I love cheddar cheese but you could use what you have on hand. Swiss or Pepper Jack would be great options.

Don’t forget to season! A little salt and pepper should do the trick.

Veggie Quiche No Crust

Pour your custard mixture into a greased pie dish and it’s ready for the oven.

There is one other thing that I love about a crustless quiche besides how delicious it is. It seems easier to pull out a nice slice for serving. 

Maybe it is just me but I struggle with pie crusts and getting a perfect slice. Without the crust it is just that much easier.

Hi Jeannie! 350°F for 15-20 minutes should do it. Keep an eye on them though to make sure they set without drying out in the oven.

This looks amazing but my husband and I are not a fan of peppers...yellow, red or green. Will it still taste good without? Any suggestions?

Susan, Absolutely! If you don't care for the peppers then just leave them out. If there are other veggies that suit your tastes better then try it out. I always say that recipes are just a guide. They can be adjusted to suit you. I hope that y'all enjoy the crustless quiche.
