Ingredients

- 4 medium zucchinis, thinly sliced
- 1 cup cherry tomatoes, halved
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 cup shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup breadcrumbs
- 2 large eggs, beaten
- 1/4 cup olive oil
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- Salt and pepper to taste
Step-by-Step Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil or cooking spray.
- Prepare the Zucchini: Thinly slice the zucchinis and place them in a colander. Sprinkle with salt and let them sit for 10 minutes to draw out excess moisture. Pat dry with a paper towel.
- Sauté the Vegetables: In a large skillet, heat the olive oil over medium heat. Add the chopped onion and garlic, sautéing until softened. Add the zucchini slices and cook for 3-4 minutes until slightly tender. Stir in the cherry tomatoes and cook for another 2 minutes.
- Combine the Ingredients: In a large bowl, mix the sautéed vegetables with the beaten eggs, shredded cheddar cheese, grated Parmesan cheese, breadcrumbs, oregano, basil, salt, and pepper. Stir until well combined.
- Assemble the Casserole: Transfer the mixture to the prepared baking dish, spreading it evenly. Sprinkle additional breadcrumbs and Parmesan cheese on top for a crispy crust.
- Bake: Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is set.
- Serve: Let the casserole cool for a few minutes before slicing and serving. Enjoy it warm as a side dish or a light main course.
