Easy Crustless Quiche Recipe

This crustless quiche is my go-to make-ahead dish for busy mornings or easy lunches. There’s no need to fuss with pie crust! Just mix everything together, pour it into a dish, and bake.

You can keep it simple or use whatever cooked vegetables, cheese, or leftover meat you have in the fridge. It’s flexible, forgiving, and always a crowd-pleaser.

Why I Love This Recipe

It’s simple and quick. Everything mixes in one bowl and bakes in about half an hour.
It’s a great recipe for meal prep. It stores and reheats well, so it’s perfect for leftovers.
It’s easy to customize. You can change up the cheese, protein, or veggies based on what you have on hand.

Ingredients

Scroll down to the recipe card for the full step by step instructions! ⬇️

Eggs: The base of the quiche, providing structure and richness.
Milk (or half and half): Adds creaminess and helps bind the ingredients. You can choose any variety of milk you like, but I prefer whole milk for a rich, custard-like texture. You can also use half and half for a richer texture.
Shredded cheese: Adds savory flavor. Cheddar, Swiss, or feta all work well.
Cooked bacon, ham, or sausage (optional): Adds protein and salt if using.
Diced vegetables: Choose your favorites, like chopped spinach, mushrooms, bell peppers, or onions.
Salt: Enhances all of the other flavors in the quiche.
Black pepper: Adds a little kick and balance to the dish.
Garlic powder (optional): For a little extra savory flavor, if you’d like to add it.

Substitutions and Variations

Dairy-free: Use a plant-based milk and dairy-free cheese alternative.

Vegetarian: Skip the meat and double up on vegetables.

Different cheeses: Try goat cheese, mozzarella, pepper jack, or a sharp white cheddar for variety. Use Swiss cheese, bacon, and onion for a take on the classic Quiche Lorraine!

Skillet: Make this crustless quiche in a cast iron skillet instead of a pie dish to create something closer to a frittata.

Tips for Success

This mouthwatering crustless quiche is extremely easy to make. For the very best results, here are a few tips:

Grease the pan well. This prevents sticking and makes cleanup easier!
Use pre-cooked ingredients. Any meat or vegetables should be cooked before adding to the egg mixture.
Let it rest before cutting. Allowing the quiche to cool slightly helps it set up and slice cleanly.

FAQ

What’s the best dish to bake this in?

A metal or ceramic 9-inch pie dish or casserole dish works best to prevent excess shrinkage. If using glass, reduce the heat slightly and keep an eye on baking time.

Can I freeze crustless quiche?

Totally! Let it cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

How do I store leftover quiche?

Store leftover quiche in an airtight container in the fridge for up to 4 days. Reheat in the microwave or in a 325°F oven until warmed through.
