When summer gardens overflow with zucchini and tomatoes, this crustless zucchini tomato quiche becomes an absolute must-make. It captures all the essence of fresh seasonal produce, wrapped in a tender, cheesy custard that’s light, satisfying, and completely crust-free. Perfect for those who love a low-carb or gluten-free twist on a classic.

This quiche is a versatile staple that works just as well for brunch as it does for a quick weeknight dinner. It pairs the mild, buttery flavor of zucchini with the juicy acidity of tomatoes, all tucked into a creamy, savory egg base. With every bite, you get the sweetness of roasted vegetables and the richness of melty cheese.

Why You’ll Love This Crustless Zucchini Tomato Quiche

You’ll appreciate this quiche for how effortlessly it comes together, especially if you’re juggling busy mornings or want something wholesome to prep ahead. No need to fuss with dough or blind baking—just slice, mix, bake, and enjoy. It also stores beautifully, making leftovers something to look forward to.

The lack of crust doesn’t mean a lack of flavor. In fact, it highlights the vegetables and cheese even more. The edges brown slightly for that satisfying finish, while the center stays soft and creamy.

What Kind of Tomatoes and Zucchini Should I Use?

You can use whatever you have on hand, but the best combination for this quiche is ripe Roma or cherry tomatoes and young, firm zucchini. Cherry tomatoes burst with flavor and add a bit of juiciness without watering down the filling. If your tomatoes are extra juicy, just give them a quick roast or blot with a paper towel. For the zucchini, smaller is better since they have fewer seeds and more flavor.

Ingredients for the Crustless Zucchini Tomato Quiche

This crustless quiche leans on simple ingredients that shine on their own, so freshness makes a big difference. Here’s what you’ll need:

Zucchini: Brings a tender, slightly sweet texture and a subtle flavor that soaks up the egg and cheese beautifully.

Tomatoes: Adds juiciness and a bright contrast to the rich eggs and cheese. Cherry or Roma tomatoes work great.

Eggs: Acts as the base and binder for the quiche. They puff slightly in the oven and hold everything together.

Milk: Keeps the custard light and creamy. You can use whole milk or a dairy-free option.

Cheese: Adds richness and flavor. A sharp cheddar, mozzarella, or a mix of both works best.

Garlic: Just a hint goes a long way to bring out the earthy notes in the vegetables.

Onion: Optional, but a lightly sautéed onion adds savory depth.

Salt & Pepper: Essential to season the filling and enhance every bite.

Herbs: Fresh basil or thyme complement the vegetables beautifully.

How To Make the Crustless Zucchini Tomato Quiche

Step 1: Prep the Vegetables

Slice the zucchini thinly and halve the tomatoes. If using onion, dice and sauté it until soft and lightly golden. Set aside to cool.

Step 2: Mix the Custard

In a large bowl, whisk together the eggs, milk, garlic, salt, pepper, and chopped herbs. Stir in half of the cheese.

Step 3: Assemble the Quiche

Lightly grease a pie dish or baking pan. Spread the zucchini, tomatoes, and onions evenly across the bottom. Pour the egg mixture over the veggies and top with the remaining cheese.

Step 4: Bake to Golden Perfection

Bake at 375°F (190°C) for 35 to 40 minutes, or until the top is set and golden. Let it cool slightly before slicing.
