Cheese and onion quiche is a great vegetarian addition to a brunch or lunch menu.  The caramelized onion gives this dish lots of flavor!  Feel free to use a pre-made crust or whip up a grain-free, low carb coconut flour pie crust.

Cheese and Onion Quiche

Every Christmas morning I make a breakfast dish that we can all enjoy while opening presents and sipping on coffee.

My go to casserole that I make often for lots of family gatherings is this Green Chili Frittata (I need to desperately update this post!).  Everyone likes it and it’s vegetarian, so my daughter can enjoy it too!

This year I made this cheese and onion quiche.  Boy was it delicious, so this quiche will be making an appearance often at our house!

Crust or no-crust quiche options

There are lots of options when preparing this quiche, including the type of crust to use.

Since I also served this Mixed Fruit Breakfast Casserole and Crustless Spinach Quiche, I kept this cheese and onion quiche low carb by using my Coconut Flour Pie Crust.

If you or your guests are used to tasting and serving grain-free based crusts, then you’ll love the low carb crust. 

If you are slowly transitioning to keto or low carb, then I would stick to the traditional style crust or feel free to make this quiche crustless!

Here are some other pie crust options:

• Low Carb Almond Flour Pie Crust
• Pre-Made Pie Crust (no judging here!)
• Gluten Free Pie Crust Recipe

Steps to make a quiche

Let’s make this baby!

First, you want to caramelize the onions to bring out all that delicious flavor! 

The key to caramelizing onions is to be patient when cooking these.  This step can’t be hurried, but you can get them as golden as you would like, but you need to watch them like a hawk!

Next, Prepare the crust or if you are opting for no crust make sure the pie pan is greased generously.

Whisk together the eggs and cream with the herbs and set aside.

To assemble the quiche we are layering half of the cooked onions, then half of the cheese.  Repeat and cover with the egg and cream mixture.

Finally, bake until firm and nicely golden.
