Crustless Cauliflower Quiche

You’ll find heaps of roasted cauliflower and melted cheese in this Crustless Cauliflower Quiche. It’s an easy and crowd-pleasing brunch recipe and is even great for meal-prepping!

There’s so much to love about a classic quiche recipe: sautéed vegetables, melted cheese, and fluffy eggs all baked together in a flaky pie crust. The only downfall? It isn’t a speedy meal. That’s why I’m pushing the crust aside and making this quick and easy Crustless Cauliflower Quiche instead.

Whether you’re looking for your next show-stopper to serve with bloody marys at brunch or need an easy recipe for meal prep, you can always count on this cauliflower quiche. It’s completely crustless, which means it’s really easy to make and prep! You can’t beat the delicious and savory fillings either.

Each bite is packed with roasted cauliflower, fresh herbs, parmesan, and burrata cheese in a custard-like egg filling. The creamy, cheesy bites will have you going back for more!

Recipe features

• A healthy and naturally vegetarian, gluten free, and keto brunch recipe.
• Crustless quiches are so much easier and quicker to prep!
• Each slice has the perfect ratio of veggies to ooey gooey cheese.

Ingredient notes:

• Eggs - Use the freshest eggs you can find for the best flavor.

• Roasted cauliflower - We all know that roasted cauliflower is SO much better than raw or steamed cauliflower. The oven brings out the vegetable’s natural buttery flavor and tender texture. You can bake the cauliflower with additional seasonings if you’d prefer, but I think it’s fantastic with just olive oil!

• Almond milk - Milk is necessary for a soft and fluffy quiche. Almond milk, ½ almond milk and ¼ half and half, another dairy free milk, or regular milk will all work here.

• Herbs - Green onion with fresh parsley and tarragon give each bite a huge boost of flavor. Try not to replace these three with anything else, as they all pair so perfectly with eggs.

• Parmesan cheese - Cheese is a must in any quiche recipe and I chose to use parmesan. If you don’t have a block of fresh parmesan at home, feta cheese, goat cheese, gruyere, or mozzarella are all tasty alternatives.

• Burrata cheese - Burrata on top of the quiche becomes stretchy and creamy once it melts in the oven.

Step-by-step instructions

Step 1: Roast the cauliflower. Toss the cauliflower florets in olive oil, then lay them on a baking sheet. Roast in the oven until tender.

Step 2: Prepare the egg mixture. Whisk the eggs, milk, onion, parsley, tarragon, parmesan, salt, and black pepper together in a large bowl. Stir the cauliflower into the bowl once it’s done roasting.

Step 3: Bake the quiche. Pour the filling into your prepared pie pan and place dollops of burrata on top. Bake the quiche until the center is set.

Step 4: Slice and enjoy. Take the quiche out of the oven and add more burrata on top. Slice and enjoy!

Expert tips and FAQs

• Break the cauliflower into bite-sized pieces to help them roast faster and to avoid large chunks in the quiche.
• Make ahead tip: roast the cauliflower up to two days in advance and store it in a container in the refrigerator. That way, it's ready to go when you want to whip up this quiche.
• A 9-inch pie pan is best but you could use a round cake pan instead.
• Feel free to add even more to this quiche, like bacon, diced ham, peas, more roasted vegetables, or leafy greens.
• Top your cauliflower quiche with arugula, grated parmesan, or dollops of kale pesto for a gorgeous presentation.
• You can use my gluten free pie crust if you’d prefer to bake it in a crust (make sure to blind bake it first).

Is a quiche the same as a frittata?

A quiche and frittata are both technically “egg pies” but have a few key differences. Quiches are baked in the oven and have a custard-like, melt-in-your-mouth texture because of the milk and egg filling. Fritattas have a similar texture and filling but are cooked in a skillet on the stove and then either flipped or finished in the oven.

How long does it take to bake a quiche?

It will need 40 to 45 minutes to bake in the oven. You’ll know it’s done when the center is no longer runny and a knife inserted in the middle comes out clean.

Can you make quiche ahead of time?

Yes, this crustless quiche can easily be made 1 day ahead of time and kept in the fridge to enjoy over the next few days. If you’re not ready to bake it quite yet, you can save time by roasting the cauliflower ahead of time.

Storage

Refrigerator: Wrap the baked quiche in plastic or store the individual slices in airtight containers for up to 4 days in the refrigerator. 

Freezer: Let the cauliflower quiche cool, then wrap it in foil and freeze for up to 3 months.
