Easy crustless quiche

We love eating quiche around here because it’s so easy to make for breakfast. It’s like a pie meets omlette and requires very little work to get out perfectly.

This crustless quiche is super fast to pull together and the flavors are wonderful.

Tips for making crustless vegetarian quiche

You can omit any of the veggies from the recipe or use a smaller amount if you don’t have much on hand. I have found that this makes it much easier for using up half the onions or tomatoes I keep storing in my fridge.

If you want to make this quiche in a pie crust I recommend making it in one that has been baked at 425 degrees F for 10 minutes prior to filling so that it’s perfectly cooked at serving time and not soggy.

FAQ’s about no crust vegetable quiche

How long is quiche good for?

Leftover quiche is good for about 3-4 days if stored in an airtight container in the fridge. I think it tastes best when eaten within the first 24 hours though as that’s when the texture, moisture, and flavor are really great.

Can I make crustless quiche in advance?

Absolutely! Go ahead and mix up everything you need now (as if you were about to pour it into a pie plate and bake it) and instead, keep it stored in a covered bowl or gallon-sized Ziploc baggie in the fridge. It can last up to two days like this but can be a great way to wake up to quiche on a busy morning.
Do not store the quiche filling in a glass pie plate and then move directly to a hot oven. If keeping in the pie plate until ready to bake, make sure to let it sit at room temperature for about 30 minutes as the oven preheats before baking.

How to make crustless veggie quiche

In a skillet over medium heat add 2 tbsp of olive oil and your onions, sautee until translucent.

Add 1 more tbsp olive oil and the diced mushrooms. Sautee until the onions are lightly browned and the mushrooms are soft.

Add eggs, stirring until well mixed.
