Meal Prep Vegetarian Crustless Quiche
Crustless quiche is one of my favorite ways to meal prep my breakfast for any busy week.
What I love about this recipe is that it’s so easy to whip up and get into the oven while I do ALL the things.
It was made for multitaskers!
We love to make the quiche on Sunday evening and eat it all week for breakfast.
The fact that it’s crustless helps it maintain freshness into the week because there’s nothing to become soggy.
How do you make Crustless Quiche?
1. Gather all ingredients and chop, dice, etc. (takes about 15 minutes).
2. Saute vegetables in a skillet.
3. Place into sprayed baking dish.
4. Whisk eggs with other ingredients and add to baking dish.
5. Bake about 40 minutes; broil 3-4 minutes to brown the top, if needed.
How to meal prep crustless quiche for breakfast:
~ After baking the quiche, allow to completely cool.
~ Cut into desired portions and pack into small containers.
~ Heat individual pieces in a microwave at home or at work.
This recipe is substitution-friendly:
It’s quite versatile, actually!
You can add just about any vegetable or cheese to this recipe.
I even like to add rice to it sometimes, and I almost always use egg whites in partial substitution for the eggs.
Just a personal preference, but the possibilities are endless!
It’s also a perfect way to use up those fresh veggies in the fridge that need to be used!
