Crustless Quiche

No time to fuss with crust? You'll love this easy crustless quiche! Filled with broccoli and cheese, it's healthy, satisfying, and delicious for any meal.

This crustless quiche recipe is for those of us (ahem, me) who love quiche but don’t love making pie crust. Like a classic quiche, it’s flavorful and satisfying, the rich egg custard studded with broccoli, herbs, and cheese. But without a crust to fuss with, it’s SO much easier to make!

This crustless quiche is the perfect simple-yet-special dish for the hectic holiday season. Serve it for brunch alongside fresh fruit and mimosas, or make it for an easy weeknight dinner. If you’re lucky enough to have leftovers, warm them up for a healthy breakfast or lunch the next day. You’ll love having this versatile recipe in your back pocket!

What is the difference between a crustless quiche and a frittata?

Great question! Traditionally, quiche is a savory egg custard tart or pie—yes, with a crust. The famous bacon, cheese, and onion quiche Lorraine originated in northeast France with influence from neighboring Germany.

A frittata, on the other hand, is a classic Italian egg dish. It doesn’t have a crust.

So, if you make a quiche without a crust, is it any different from a frittata?

Yes! This crustless quiche recipe and my frittata recipe differ in two key ways:

• Milk to egg ratio. Quiche recipes typically call for a higher milk to egg ratio than frittata recipes do. For reference, when I make a frittata, I use 8 eggs and 1/4 cup milk. When I make this crustless quiche, I use 6 eggs and 1/2 cup milk. Some quiche recipes call for even more milk or cream!
• Cooking method. Frittatas are typically cooked in a skillet. The eggs start cooking on the stovetop and finish in the oven. In a crustless quiche, the eggs bake entirely in the oven.

Crustless Quiche Ingredients

Here’s what you’ll need to make this crustless quiche recipe:

• Eggs and unsweetened almond milk – They create the egg custard. Feel free to swap out the almond milk for 2% or whole milk if you prefer.
• Shallots – They infuse the crustless quiche with savory, umami flavor.
• Broccoli – It adds satisfying texture to the delicate egg custard.
• Gruyere cheese – For rich, nutty flavor.
• Extra-virgin olive oil – For greasing the pie dish and sautéing the vegetables.
• Fresh herbs – They add depth of flavor to this simple recipe. Take your pick between thyme or chives. The thyme is citrusy and earthy. The chives are fresh and oniony.
• And salt and pepper – To make all the flavors pop!

How to Make Crustless Quiche

This crustless quiche recipe is easy to make!

Start by whisking the eggs. Crack them into a large bowl and beat them with the milk, salt, and pepper until no streaks of egg white remain.

Next, cook the veggies. Sauté the shallots over medium heat until they soften, about 4 minutes. Then, add the broccoli and water and cook, stirring, until the water evaporates and the broccoli is bright green, another 4 minutes or so. You want the broccoli to just lose its raw bite.

You’re ready to assemble the crustless quiche. Lightly oil a 9- or 9.5-inch pie plate and evenly spread the vegetables on the bottom. Sprinkle the shredded cheese on top.

Pour in the egg mixture. I like to gently shake the pie pan to distribute the eggs and remove any air bubbles. Finally, top with the thyme or chives!

Bake the crustless quiche at 350°F for 30 to 40 minutes, or until the edges are golden brown and the eggs are set. Remove from the oven, slice, and serve!

Tip

Wondering what to serve with crustless quiche? This recipe pairs nicely with a green salad for lunch or dinner. For a simple breakfast, serve it alongside a fresh fruit salad and toast.

Recipe Variations

I love this crustless quiche recipe as written, but it works well with a variety of add-ins. Feel free to change it up to suit your tastes or use what you have on hand. Here are a few ideas to get you started:

• Toss in other veggies. Replace the broccoli with sautéed spinach, mushrooms, or asparagus. Roasted butternut squash would be delicious too!
• Change the cheese. Use cheddar, feta, or Swiss cheese instead of Gruyere.
• Swap the herbs. Not feeling thyme or chives? Add tarragon, basil, or chopped fresh rosemary instead.

Let me know what variations you try!
