Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Zucchini, thinly sliced
Cherry or grape tomatoes, halved
Fresh basil, chopped
Eggs
Milk or half-and-half
Shredded cheese (cheddar, mozzarella, or your favorite blend)
Garlic powder
Onion powder
Salt
Black pepper
Olive oil or butter (for greasing the dish)

Directions

I preheat the oven to 375°F (190°C) and lightly grease a 9-inch pie dish or baking dish with olive oil or butter.
I sauté the thinly sliced zucchini in a pan for a few minutes until it starts to soften. This helps prevent the quiche from becoming watery.
In a mixing bowl, I whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until well combined.
I stir in the chopped fresh basil and shredded cheese.
I spread the sautéed zucchini evenly in the greased dish, scatter the halved tomatoes over the top, then pour the egg mixture over everything.
I gently shake the dish to level the mixture, then bake for 35–40 minutes, or until the center is set and the top is lightly golden.
I let it cool for 5–10 minutes before slicing and serving.

Servings and timing

This recipe yields 6 servings and takes about 45 minutes total—including prep, cooking, and cooling time. It’s ideal for breakfast, brunch, or a light dinner with a side salad.

Variations

I sometimes add sautéed onions, spinach, or bell peppers for extra veggies.
For a richer texture, I use half-and-half instead of milk.
I’ve made it with crumbled feta or goat cheese for a tangy twist.
If I want a bit of spice, I add a pinch of red pepper flakes or chopped jalapeños.
When I’m out of basil, I swap in fresh parsley or dill.

Storage/Reheating

Leftovers keep well in the fridge for up to 4 days. I store them in an airtight container and reheat slices in the microwave or oven until warmed through. It also tastes great cold, straight from the fridge. I don’t recommend freezing, as the texture can change after thawing.

FAQs

Can I make this ahead of time?

Yes, I often bake it the night before and reheat slices as needed. It holds up well in the fridge and tastes even better the next day.

Do I have to sauté the zucchini first?

I highly recommend it. It removes excess moisture and keeps the quiche from becoming soggy during baking.

What’s the best cheese to use?

I love using sharp cheddar or a mozzarella blend, but Swiss, Gruyère, or even Parmesan work beautifully too.

Can I use dried basil?

Fresh basil gives the best flavor, but in a pinch, I use 1 teaspoon of dried basil. I mix it into the egg mixture to let it rehydrate while baking.

Is this quiche gluten-free?

Yes, since it’s crustless, this recipe is naturally gluten-free—just be sure to check your cheese and spices to be safe.
