Crustless Spinach Quiche

Crustless Spinach Quiche is easy to make for breakfast, lunch, or dinner. It is also normal food that happens to be gluten free! 

Need an easy recipe that works well for breakfast, lunch, or dinner? Try quiche. More specifically try this easy crustless spinach quiche. 

One of the great things about quiche is that you can change it up. I have several quiche recipes that I have shared over the years. (Links for my other quiche recipes are below. Scroll down for them.)

Crustless Spinach Quiche

A quiche can be meatless or cooked bacon, sausage, or ham can be added. Quiche can also contain vegetables like spinach, broccoli, onions, or tomatoes. 

You can change up the cheese too. Mozzarella, cheddar, Colby Jack, and many other cheeses work well in quiche. Use what you like or what you have on hand. 

Once you have a basic quiche recipe that you love, like this crustless one, it is easy to change up the other ingredients.

Why Do I Make Crustless Quiche?

You might be wondering why I make many of my quiches crustless. The main reason is that I like them better. I love pie crust for pies, but for quiches I have found that I prefer no crust. 

A crustless quiche also makes it gluten free. Or at least it makes most quiches gluten free. I love my gluten free pie crust recipe and it would work well for a quiche crust, but again I prefer it without the crust. 

Leaving the crust off also saves fat and calories. You will find a lot of high calorie high fat recipes on my site, but when it comes to quiche I would rather have that fat and calories in the ingredients not the crust. 

When I make it crustless I don’t feel bad about making a cheesy filling or using heavy cream.

Can Quiche Be Made Ahead?

Yes, quiche is great made ahead and reheated. I make it this way all the time. I almost always make several quiches and then we reheat them for breakfast and lunches the next few days. Bake as directed, let cool, store it in the refrigerator, and reheat when needed. 

Can I Add a Crust to a Crustless Quiche?

Yes, just use your favorite pie crust recipe or quiche crust recipe. 

Are Frittatas and Crustless Quiches the Same?

Frittatas and crustless quiches are similar, but not exactly the same. Many people use them to describe the same dish though.

Both frittatas and crustless quiches have no crust. A crustless quiche has more of a egg custard for the filling while frittatas tends to have a more hearty filling with more ingredients. 

There is also often a difference in how they are cooked. Frittatas are often started on the stove and finished in the oven. Crustless quiches are usually just baked in the oven.

  1. Thanks for this! Question, is there anything I can use instead of the heavy cream?

    • You could use half and half or even milk. The cream makes it richer and I think better tasting, but milk would work. However, half and half and milk are not as thick, so I would cut back the amount slightly if I was going to use milk or half and half. I hope that helps.
