Full Recipe

Ingredients

3 medium zucchini, grated and drained
1 onion, finely chopped
3 garlic cloves, minced
5 large eggs
1 cup (240 ml) milk or half-and-half
1 cup shredded cheese (cheddar, mozzarella, or a mix)
½ cup Parmesan cheese, grated
2 tablespoons olive oil
½ teaspoon dried oregano
½ teaspoon dried thyme or dill
Fresh parsley, chopped, for garnish
Salt and black pepper, to taste

Cooking Directions

Prepare the Zucchini: Grate the zucchini and place it in a colander. Sprinkle with a little salt and let it sit for 10 minutes to release excess water. Squeeze out the liquid using a clean kitchen towel or cheesecloth. This ensures the quiche won’t turn watery.
Cook the Aromatics: Heat olive oil in a skillet over medium heat. Add the chopped onion and sauté for 3–4 minutes until softened. Add the garlic and cook for another 1–2 minutes until fragrant. Remove from heat and let it cool slightly.
Make the Egg Mixture: In a large mixing bowl, whisk together eggs, milk, oregano, thyme, salt, and pepper. Add the Parmesan cheese and stir to combine.
Combine Ingredients: Add the grated zucchini, sautéed onion, garlic, and shredded cheese into the egg mixture. Mix well until all ingredients are evenly distributed.
Bake the Quiche: Preheat the oven to 180°C (350°F). Grease a baking dish or pie dish with olive oil. Pour the mixture into the dish and smooth the top. Bake for 35–40 minutes, or until the quiche is set in the center and lightly golden on top.
Cool and Serve: Let the quiche cool for about 5–10 minutes before slicing. Garnish with fresh parsley and serve warm or at room temperature.

The Origins and Inspiration Behind the Dish

Quiche originated in France, most famously the Quiche Lorraine with its buttery crust and creamy filling. Over time, crustless versions became popular for their simplicity and lighter nutritional profile. The herb-infused zucchini variation takes inspiration from Mediterranean and garden-to-table cooking traditions, where fresh vegetables and herbs are the stars of the meal. By keeping it crustless, it also reflects modern preferences for gluten-free and low-carb options while maintaining the classic essence of a quiche.

Ingredient Spotlight

Zucchini is the highlight here, bringing natural sweetness, moisture, and nutrients. Eggs are the backbone of the quiche, giving it structure and richness. Cheese, both shredded and Parmesan, delivers that gooey, comforting texture while enhancing flavor. Herbs like oregano and thyme elevate the dish with an aromatic depth, transforming simple ingredients into something memorable. Finally, olive oil ties everything together with healthy fats and a subtle Mediterranean flair.

Storage and Reheating Tips

This quiche stores beautifully, making it ideal for meal prep. Keep leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, warm slices in the oven at 160°C (320°F) for 10–12 minutes or microwave on medium heat for 1–2 minutes. It can also be enjoyed cold, which makes it perfect for school or work lunches. Avoid freezing as the texture of eggs can become rubbery after thawing.

Common Variations to Try

You can customize this quiche endlessly. Add sautéed mushrooms for an earthy flavor, or spinach for extra greens. Swap zucchini with grated carrots or a mix of summer squash. For cheese lovers, try feta or goat cheese instead of Parmesan. If you prefer bold flavors, add a pinch of chili flakes or smoked paprika. For a Mediterranean twist, toss in olives or sun-dried tomatoes. The recipe is forgiving, so you can experiment with what you have on hand.

Pairing Recommendations

This quiche pairs well with a crisp green salad dressed in lemon vinaigrette for a refreshing contrast. It’s also delicious alongside roasted potatoes or fresh fruit for brunch. For drinks, serve it with iced tea, sparkling water with lemon, or even a chilled white wine like Sauvignon Blanc or Pinot Grigio if you’re hosting guests. Its versatility makes it a star on both casual and elegant tables.
