How To Make the Crustless Zucchini Tomato Quiche

Step 1: Prep the Vegetables

Slice the zucchini thinly using a mandoline or sharp knife. If using juicy tomatoes, remove excess seeds. Pat both veggies dry with paper towels to reduce moisture.

Step 2: Sauté for Extra Flavor (Optional but Recommended)

Heat a little olive oil in a pan and sauté zucchini for 2-3 minutes just until slightly softened. Let cool.

Step 3: Whisk the Egg Mixture

In a large mixing bowl, whisk together the eggs, milk (or half-and-half), salt, pepper, and herbs. Stir in the shredded cheese.

Step 4: Combine and Assemble

Fold in the prepared zucchini and tomatoes into the egg mixture. Pour the mixture into a greased 9-inch pie dish.

Step 5: Bake to Perfection

Preheat oven to 375°F (190°C). Bake the quiche for 35-40 minutes or until the center is set and the top is golden. Let it cool for 10 minutes before slicing.

Frequently Asked Questions

Can I make this quiche dairy-free?

Absolutely. Use a dairy-free milk alternative like unsweetened almond milk and a plant-based cheese or skip the cheese altogether. The texture will still be soft and delicious.

Should I peel the zucchini first?

No need! The skin adds texture and color, and it becomes tender during baking.

What’s the best cheese for this quiche?

Mozzarella is great for meltiness, while Parmesan adds a salty bite. You could also use cheddar, goat cheese, or feta for variety.

Can I add other vegetables?

Definitely. Bell peppers, spinach, mushrooms, or even caramelized onions can work well. Just be sure to sauté and remove moisture beforehand.

How do I know when it’s fully cooked?

The center should no longer jiggle, and a knife inserted should come out clean. You can also lightly press the top—it should feel firm.

Can I make it ahead of time?

Yes! Bake it the night before and refrigerate. Reheat slices as needed throughout the week.
