Preparation Phase & Tools to Use
Getting your kitchen ready is a key step to ensuring success with this quiche. Begin by organizing your workspace and gathering all necessary tools. A 9-inch pie dish is essential for shaping the quiche. Have a reliable set of measuring cups, a sharp knife, and a sauté pan on hand for chopping and cooking your vegetables. You’ll also need a whisk to blend the eggs and milk smoothly.
It’s important to preheat your oven to ensure even cooking throughout. A sturdy baking sheet beneath your pie dish can help distribute heat more uniformly, reducing the risk of overcooking the edges. Greasing your pie dish will not only prevent sticking but also aid in achieving that golden finish atop the quiche. With these steps and tools, you’re set to create a quiche worth savoring.

Ingredients
- 4 large eggs
- 1 cup milk (whole or 2%)
- 1 tbsp olive oil
- 1 medium zucchini, thinly sliced (about 2 cups)
- 1 medium tomato, sliced
- 1 small onion, finely chopped
- ½ cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- ½ tsp dried oregano or Italian seasoning
- Salt and black pepper, to taste
- Fresh basil leaves, for garnish
Instructions
Step 1: Preheat Your Oven
To kick things off, set your oven to preheat at 375°F (190°C). While this is taking place, go ahead and grease your 9-inch pie dish to ensure a seamless release of the quiche post-bake.
Step 2: Cook the Veggies
Heat olive oil in a sauté pan over medium heat. Add the finely chopped onion and cook for around 3 minutes, allowing it to soften and release its natural sweetness. Introduce the sliced zucchini and continue sautéing for an additional 5 minutes, lightly seasoning as you go. This step imparts a depth of flavor essential for the quiche.
Step 3: Whisk Your Eggs
In a separate mixing bowl, break the eggs and whisk them gently with the milk. Sprinkle in the oregano or Italian seasoning, along with salt and pepper to taste. Introduce both the mozzarella and Parmesan cheeses, stirring until the mixture melds together smoothly.
Step 4: Assemble the Quiche
Arrange the cooked zucchini and onion blend evenly across the base of the greased pie dish. Place the fresh tomato slices on top, evenly spaced. Pour the egg mixture over everything, ensuring an even distribution.
Step 5: Bake to Perfection
Position the pie dish in the oven and allow it to bake for approximately 35-40 minutes. Look for a set consistency with a lightly golden top. Upon reaching perfection, remove the quiche and let it cool for around 5 minutes before serving.
Step 6: Garnish and Serve
Finish with a touch of fresh basil leaves for a pop of color and fresh aroma. Slice the quiche and savor it while warm or at room temperature.

Variations
- Protein: Enhance with cooked bacon bits or diced ham for added texture and flavor.
- Vegetables: Swap zucchini with spinach or bell peppers for different nutritional benefits.
- Spices: Experiment with thyme or cayenne pepper for a new layer of taste.
Cooking Notes
- Using fresh summer vegetables will maximize flavor; however, frozen can be used if fresh isn’t available – just ensure they are thawed and drained first.
- Allow the quiche to set for a few minutes before slicing to enable cleaner cuts and maintain its structure.
Serving Suggestions
- Pair with a mixed green salad for a refreshing counterbalance.
- Serve alongside a warm crusty bread to accompany each cheesy bite.
Tips
- For a richer flavor, incorporate goat cheese or feta into the egg mixture.
- Leftovers can be refrigerated for up to 3 days and make for an excellent quick lunch option.

FAQs
Can I make this quiche ahead of time?
Absolutely! You can prepare and bake the quiche in advance. Allow it to cool completely, wrap it securely, and refrigerate. It reheats easily in the oven or microwave.
What other cheeses can I use?
Creamy, meltable cheeses such as Gruyère or cheddar can substitute for mozzarella. The Parmesan’s nutty flavor adds depth, but can also be swapped with Pecorino Romano.
How can I make it gluten-free?
As this recipe is naturally free of flour or crust, it’s inherently gluten-free. Always verify that packaged ingredients, like cheese, are handled in facilities that avoid gluten, to prevent cross-contamination.
Why is my quiche watery?
Ensure all moisture is cooked off from the vegetables before adding them to the dish, and fresh tomatoes should be used instead of canned to prevent excess liquid.
