Full Recipe

Ingredients

• 2 eggs

• Salt, to taste

• 2 medium zucchinis, grated

• 1 onion, finely chopped

• 3 cloves of garlic, minced

• 2 tomatoes, diced

• 2 tablespoons vegetable oil

• 1 teaspoon mixed dried herbs (thyme, oregano, basil)

• 1 teaspoon paprika

• ½ teaspoon black pepper

• A handful of fresh parsley, chopped

• 100 g mozzarella cheese, shredded

• 100 g mushrooms, sliced

• 1 carrot, grated

• 1 teaspoon dry garlic powder

• 50 g sour cream

• 2 spring onions, chopped

• A small bunch of fresh dill, chopped

• 100 g cheese (cheddar or gouda), shredded

Cooking Directions

1. Prepare the zucchini by grating them and sprinkling with a little salt. Let them sit for 10 minutes to release excess water, then squeeze them using a clean towel or cheesecloth.

2. In a skillet, heat one tablespoon of vegetable oil over medium heat. Add the onion and cook until translucent, then add the minced garlic and sauté until fragrant.

3. Stir in the tomatoes and cook for about 5 minutes until softened. Add the mushrooms and grated carrot, cooking until tender. Season with mixed herbs, paprika, black pepper, and a touch more salt if necessary.

4. In a large bowl, beat the eggs. Add the sautéed vegetables, drained zucchini, parsley, dill, spring onions, sour cream, and shredded mozzarella. Mix until everything is well combined.

5. Preheat your oven to 180°C (356°F). Grease a baking dish with the remaining tablespoon of vegetable oil. Pour in the mixture, spreading it evenly. Top with the shredded cheese.

6. Bake for 40 minutes, or until the casserole is golden brown and the center is fully set.

7. Allow to cool slightly before slicing and serving. Garnish with extra herbs if desired.

The Origins and Inspiration Behind the Dish

Mediterranean cuisine is famous for its focus on fresh, seasonal produce, and this casserole takes inspiration from that philosophy. The zucchini, tomatoes, and herbs reflect traditional ingredients often found in kitchens across Greece, Italy, and the Levant. Casseroles themselves are universal comfort foods, but this version marries the rustic, layered approach of Mediterranean cooking with the ease of modern baking. The result is a dish that feels timeless yet practical.

Ingredient Spotlight

Zucchini takes center stage here, offering a mild flavor that soaks up the herbs and seasonings beautifully. It also adds moisture without weighing the dish down. Tomatoes provide acidity and sweetness, balancing the richness of the cheese. Mushrooms contribute umami depth, while carrots sneak in natural sweetness and extra nutrition. Fresh dill and parsley bring that unmistakable Mediterranean freshness, brightening the entire casserole. Finally, the cheeses—mozzarella for gooeyness and cheddar or gouda for sharpness—pull everything together in a luscious, golden topping.

Storage and Reheating Tips

This casserole keeps well, making it an excellent make-ahead option. Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply place individual slices in the oven at 160°C (320°F) for about 10–15 minutes until warmed through. The oven keeps the texture intact, but if you’re in a hurry, the microwave works fine too—just expect a slightly softer consistency. For longer storage, freeze portions wrapped in foil or airtight containers for up to 2 months. Thaw overnight in the fridge before reheating.

Common Variations to Try

This recipe is endlessly flexible. For extra protein, you can mix in shredded chicken, turkey, or even tuna. To make it vegan, swap the eggs with flax eggs, replace the sour cream with plant-based yogurt, and use vegan cheeses. If you love a kick of heat, sprinkle in chili flakes or chopped fresh chilies. Changing up the cheeses gives the casserole a whole new personality—feta adds tanginess, goat cheese adds creaminess, and parmesan adds a sharp, nutty bite. You can also add extra vegetables like bell peppers, spinach, or even eggplant for more layers of flavor and nutrition.

Pairing Recommendations

This casserole works beautifully with light, fresh sides. A simple cucumber and tomato salad with olive oil and lemon makes a refreshing pairing. If you’d like a more filling option, serve it with warm pita bread or crusty sourdough to soak up the flavors. For a protein boost, pair it with grilled chicken, lamb skewers, or baked fish. If you’re pouring a glass of wine, go for something light and crisp like Sauvignon Blanc or a delicate Pinot Noir to complement the flavors without overwhelming them.

Health Benefits

Eating this casserole means you’re fueling your body with a balanced mix of protein, fiber, and vitamins. Zucchini and carrots provide antioxidants and vitamin A for eye health. Tomatoes offer vitamin C and lycopene, which supports heart health. Mushrooms are a great source of B vitamins and minerals, while fresh herbs like dill and parsley contribute micronutrients and antioxidants. With its emphasis on vegetables, this dish is nutrient-dense without being heavy, which aligns perfectly with the Mediterranean diet known for supporting long-term health and wellness.

The Mediterranean Vegetable and Zucchini Casserole is a dish that manages to be both nourishing and indulgent.
