This Gluten-Free Crustless Quiche recipe is easy, healthy & delicious! Perfect for a special brunch or quick weeknight dinner!

If you haven’t noticed, I’m all about meals that are quick, easy and healthy. Don’t get me wrong, there are days when I find being in the kitchen for hours therapeutic and fun…but there are also seasons of life that call for all things fast and simple (like when you’re 39+ weeks pregnant with baby #)!

This Gluten-Free Crustless Quiche is such a great recipe! It can be served as part of a special brunch or as a quick weeknight dinner! Also check out this easy frittata recipe, egg bake (egg casserole) and this hash brown quiche!

To be honest, I’m grateful for eggs. I know it sounds silly to be thankful for a food, but eggs are such a wonderful versatile option when you’re trying to eat healthy on a budget! This easy crustless quiche recipe is a great recipe to have in your tool belt for busy evenings!

How to makeGluten-Free Crustless Quiche

Making this recipe is super easy, but I’ll give you a few tips to ensure your success!

1. Sauté the vegetables.

Start bysautéingthe vegetables and letting them cool before adding them to the egg mixture. This ensures that they are softer and not super crunchy. Then, you really have a classic mix, dump, & bake situation!

2. Choose your baking dish

You can bake thisGluten-Free Crustless Quiche in any 9″ or 10″ round dish. I have used a cast iron skillet as well as a glass pie plate! If you don’t care about it being round, feel free to bakeit in a 9×9″ pan or even in muffin tins for a quick grab and go breakfast {although you will have to reduce the baking time with this option}!

Gluten-Free Crustless Quiche: Ingredients & Substitutions

This Crustless Quiche is a very versatile recipe! Here are a few potential substitutions!

Veggies:Toss any veggies you would like in here! This can be a great “clean out the veggie drawer” recipe!
Milk:If you’d like a dairy free option, unsweetened almond milk can be used in place of regular milk!
Tapioca Flour:This is a gluten-free baking staple in my pantry. However, if you don’t keep it on hand you can substitute cornstarch, arrowroot powder, all-purpose gluten-free flour, or regular flour {not gluten free}!
Spices:As you know I’m a fan of using powdered spices, especially when trying to keep meals kid-friendly! You absolutely can substitute the real thing, e.g. minced garlic for garlic powder, diced onion for onion powder, etc. Just sauté them with the veggies!
Honey Mustard:Any kind of mustard is an acceptable substitute!
