What Ingredients are in Crustless Zucchini Tomato Quiche?
This crustless quiche brings together fresh garden veggies, savory herbs, and creamy cheese in perfect harmony—without any fussy pastry work.
The beauty of this recipe lies in its simplicity and how it transforms everyday ingredients into something that feels special enough for company but easy enough for a weeknight dinner.
Let’s break down exactly what you’ll need to create this delightful dish.
- 1 tablespoon olive oil
- 1 small onion, finely chopped
- 2 medium zucchinis (about 3 cups), thinly sliced
- 2 medium tomatoes, seeded and diced
- 3 large eggs
- 1 cup milk (whole or 2%)
- ½ cup heavy cream (or additional milk)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 2 cloves garlic, minced
- 1 teaspoon dried basil (or 1 tablespoon fresh basil, chopped)
- ½ teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Pinch of red pepper flakes (optional)
The recipe offers some flexibility with the ingredients.
If you’re watching calories, you can substitute the heavy cream with more milk, though you’ll lose a bit of that luxurious texture.
Fresh herbs will always provide brighter flavor than dried, so don’t hesitate to use fresh basil if you have it on hand.
And while the recipe calls for mozzarella and Parmesan, this quiche works beautifully with almost any cheese you have in your refrigerator—gruyere, cheddar, or even goat cheese can create delicious variations on the theme.
How to Make this Crustless Zucchini Tomato Quiche
Making this quiche is wonderfully straightforward, beginning with preheating your oven to 375°F (190°C).
While that’s warming up, grab a 9-inch pie dish or quiche pan and give it a good coating of cooking spray or butter to prevent sticking. This simple step saves so much frustration later—nothing worse than watching half your beautiful quiche refuse to leave the pan.
Next, heat 1 tablespoon of olive oil in a large skillet over medium heat and add your finely chopped small onion, cooking for about 3 minutes until it becomes translucent and soft.
Then add those 2 medium zucchinis (thinly sliced) and 2 minced garlic cloves, cooking for another 5-6 minutes until the zucchini softens but still maintains some texture. You don’t want mushy zucchini here, just tender. Remove the pan from heat and let the vegetables cool slightly while you prepare the egg mixture.
In a mixing bowl, whisk together 3 large eggs, 1 cup of milk, and ½ cup of heavy cream until smooth, then stir in your seasonings—1 teaspoon dried basil (or that tablespoon of fresh if you’re using it), ½ teaspoon dried oregano, ½ teaspoon salt, ¼ teaspoon black pepper, and that optional pinch of red pepper flakes for those who enjoy a subtle heat.
To assemble, spread the cooled zucchini mixture in your prepared baking dish, scatter the 2 diced tomatoes over top, sprinkle with 1 cup of shredded mozzarella and ½ cup of grated Parmesan, then pour the egg mixture evenly over everything.
Bake for about 35-40 minutes, until the center is set and the top turns a gorgeous golden brown. A quick test with a knife inserted in the center should come out clean when it’s ready.
Crustless Zucchini Tomato Quiche Substitutions and Variations
While the traditional quiche often demands a buttery crust, this crustless version opens up a world of flexibility for ingredient swaps and creative twists.
You can easily substitute the mozzarella for Swiss, gruyere, or goat cheese for a tangy flavor profile. Not a zucchini fan? Yellow squash works beautifully instead.
For a protein boost, try adding cooked bacon, ham, or even leftover rotisserie chicken.
Vegetarian? Toss in some sautéed mushrooms or spinach.
The herbs are customizable too—rosemary, thyme, or dill can replace the basil and oregano.
Want it dairy-free? Plant-based milk and cheese alternatives perform surprisingly well here.
What to Serve with Crustless Zucchini Tomato Quiche
Looking for the perfect companions to serve alongside your crustless zucchini tomato quiche? This versatile dish pairs beautifully with so many options.
A simple green salad with vinaigrette dressing adds freshness and balances the richness of your quiche. Think arugula or mixed greens with a lemony dressing.
Fresh fruit, particularly berries or melon, provides a sweet contrast to the savory flavors.
For heartier appetites, roasted potatoes or a crusty bread work wonderfully.
And don’t forget about soup—a light tomato bisque or cucumber gazpacho in summer makes this meal complete. The combinations are endless, really.
