Ingredients

Vegetable Base:

  • 4 medium zucchinis

  • 1 medium onion, diced

  • 1 carrot, grated or finely julienned

  • 2 bell peppers (any color), diced

  • 2 tablespoons olive oil

  • Salt and pepper to taste

  • 1–2 garlic cloves, minced

  • A sprig of parsley (chopped, for mixing)

  • 120 g shredded mozzarella cheese

Binding Mixture:

  • 2 eggs

  • 1 glass (240 ml) of milk

  • 5 tablespoons all-purpose flour

  • 10 g (2 tsp) baking powder

  • Salt to taste

Creamy Garlic Sauce:

  • 2 tablespoons Greek yogurt

  • 2 tablespoons mayonnaise

  • 1 garlic clove, minced or grated

  • Juice of 1/2 lemon

  • 1 green onion, finely chopped

Step-by-Step Directions

1. Prepare the Zucchini:
Wash and grate the zucchini. Place in a large bowl, sprinkle with a generous pinch of salt, stir, and let it rest for 10 minutes. This process will draw out excess moisture, preventing the bake from becoming soggy.

2. Sauté the Onion:
Meanwhile, heat olive oil in a skillet over medium heat. Add the chopped onion and fry until translucent (about 3–4 minutes). This step enhances the natural sweetness of the onion.

3. Add Carrot and Peppers:
Grate or julienne the carrot and dice the bell peppers. Add to the onion and continue sautéing for 3–5 minutes. Then cover the pan with a lid and cook the mixture over medium heat for another 5–7 minutes until the vegetables soften. Stir occasionally to prevent burning.

4. Prepare the Zucchini:
While the other vegetables are cooking, return to your salted zucchini. Squeeze it well using a clean kitchen towel or your hands to remove as much liquid as possible. This ensures the final bake has a firm texture.

5. Combine All Vegetables:
Add the drained zucchini to the sautéed vegetables. Season with salt and freshly ground black pepper to taste. Cover and cook everything together over medium heat for 15 minutes, stirring occasionally. Add the garlic during the last 5 minutes of cooking for a flavorful finish.

6. Let the Mixture Cool:
Transfer the cooked vegetables to a greased baking dish. Allow them to cool for 5–10 minutes. Meanwhile, preheat your oven to 180°C (350°F).

7. Make the Binding Mixture:
In a separate bowl, beat the eggs, add the milk, flour, baking powder, and a pinch of salt. Whisk until smooth. This mixture will hold your bake together and give it a light, custardy consistency.

8. Combine and Spread:
Add the chopped parsley to the cooled vegetable mixture. Pour the egg-milk-flour mixture over the vegetables and mix well. Spread evenly in the baking dish.

9. Top with Cheese:
Sprinkle the mozzarella cheese evenly over the surface. It will melt into a golden, bubbling crust during baking.

10. Bake:
Place the dish in the preheated oven and bake for 35–40 minutes, or until the top is golden and firm to the touch. A toothpick inserted in the center should come out mostly clean.

Yogurt-Mayo-Garlic Sauce

11. Prepare the Sauce:
In a small bowl, mix together:

  • 2 tablespoons Greek yogurt

  • 2 tablespoons mayonnaise

  • 1 clove garlic (minced)

  • Juice of 1/2 lemon

  • 1 chopped green onion

Stir until well combined. This refreshing sauce pairs wonderfully with the warm zucchini bake.
