Ingredients
Vegetables
2 medium zucchini, grated
2 medium carrots, grated
1 small onion, finely diced
2 garlic cloves, minced
1 tablespoon olive oil
Egg Mixture
6 large eggs
½ cup whole milk or heavy cream
½ teaspoon salt
½ teaspoon black pepper
1 teaspoon Italian seasoning
¼ teaspoon paprika
Pinch of nutmeg (optional)
Cheese
1 cup shredded cheddar cheese
½ cup grated Parmesan cheese
Fresh Herbs
2 tablespoons chopped parsley
1 tablespoon chopped chives (optional)
For the Baking Dish
Butter or cooking spray for greasing
Instructions
Preheat your oven to 375°F (190°C). Grease a 9-inch pie dish or a similar baking dish with butter or nonstick cooking spray.
Grate the zucchini and carrots using the coarse side of a box grater. Place the grated zucchini in a clean kitchen towel and squeeze out as much moisture as possible. This step is important because zucchini naturally contains a lot of water, and removing the excess moisture helps the quiche bake properly without becoming watery.
Heat the olive oil in a skillet over medium heat. Add the diced onion and cook for about 3 to 4 minutes until softened. Stir in the minced garlic and cook for another 30 seconds until fragrant.
Add the grated carrots to the skillet and sauté for about 2 minutes. Then stir in the squeezed zucchini and cook for another 3 minutes to remove additional moisture. Remove the vegetables from the heat and let them cool slightly.
In a large mixing bowl, whisk together the eggs, milk, salt, pepper, Italian seasoning, paprika, and nutmeg until smooth and fully combined.
Fold in the cheddar cheese, Parmesan cheese, parsley, chives, and the cooled vegetable mixture. Stir gently until everything is evenly distributed.
Pour the mixture into the prepared baking dish and spread it evenly with a spatula.
Bake for 40 to 45 minutes, or until the center is fully set and the top is lightly golden. A knife inserted into the center should come out clean.
Allow the quiche to cool for 10 minutes before slicing. This resting time helps the quiche firm up, making it easier to cut neat slices.
Serve warm with a crisp green salad, roasted potatoes, fresh fruit, or toasted whole-grain bread.
Tips
Choose small to medium zucchini because they contain fewer seeds and less moisture than larger ones.
Always squeeze the grated zucchini thoroughly. Even a few extra minutes spent removing moisture can greatly improve the texture of the finished quiche.
Freshly grated cheese melts better than pre-shredded cheese, which often contains anti-caking agents that affect creaminess.
Avoid overbaking. Once the center is set and the edges are lightly browned, remove the quiche from the oven to keep it tender and creamy.
Let the cooked vegetables cool before adding them to the egg mixture. This prevents the eggs from beginning to cook prematurely.
For a fluffier quiche, whisk the eggs well to incorporate a little air before mixing in the remaining ingredients.
You can prepare the vegetable mixture a day in advance and refrigerate it, making assembly much quicker the next day.
Store leftovers in an airtight container in the refrigerator for up to four days. Reheat individual slices in the microwave or oven until warmed through.
This quiche also freezes well. Wrap individual slices tightly and freeze for up to three months. Thaw overnight in the refrigerator before reheating.
Variations
For a Mediterranean version, add crumbled feta cheese, chopped spinach, sun-dried tomatoes, and oregano.
Create a spicy version by mixing in diced jalapeños, crushed red pepper flakes, and pepper jack cheese.
Add cooked mushrooms for an earthy flavor that pairs beautifully with the zucchini and carrots.
Include chopped broccoli, bell peppers, or asparagus for even more vegetables and color.
Swap the cheddar for mozzarella, Swiss, Gruyère, Monterey Jack, or Gouda for a different flavor profile.
Add diced ham, shredded chicken, or turkey sausage if you’d like extra protein.
Make it dairy-free by using plant-based milk and dairy-free cheese alternatives.
Use fresh basil, dill, thyme, or rosemary instead of parsley for a unique herbal flavor.
For extra fiber, stir in chopped kale or baby spinach after lightly sautéing until wilted.
Mini crustless quiches can be made by dividing the mixture among greased muffin cups and baking for about 20 to 25 minutes.
Q&A
Can I make this quiche ahead of time?
Yes. Bake it completely, cool it, refrigerate, and reheat slices as needed throughout the week.
Why is my quiche watery?
The most common reason is excess moisture from the zucchini. Be sure to squeeze it thoroughly before cooking.
Can I eat it cold?
Absolutely. It tastes delicious both warm and chilled, making it perfect for packed lunches or picnics.
Can I freeze this recipe?
Yes. Wrap cooled slices individually and freeze for up to three months. Thaw overnight before reheating.
Can I use different vegetables?
Definitely. Broccoli, spinach, mushrooms, cauliflower, bell peppers, asparagus, and corn all work well.
Is this recipe gluten-free?
Yes. Since there is no pastry crust or flour, the recipe is naturally gluten-free. Always double-check packaged ingredients if needed.
Which cheese works best?
Cheddar offers a rich, classic flavor, but mozzarella, Gruyère, Swiss, feta, or a combination of cheeses are all excellent choices.
How do I know when it’s fully cooked?
The center should be firm with only a slight jiggle, and a knife inserted into the middle should come out clean.
