Ingredients

Scale

Vegetables

  • 2 medium zucchinis, sliced into 1/4-inch rounds
  • 4 medium tomatoes, sliced into 1/4-inch rounds
  • 1 medium onion, thinly sliced
  • 2 cloves garlic, minced

Cheese & Dairy

  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 2 tablespoons butter, melted

Seasonings & Others

  • 1 tablespoon olive oil
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • Salt and pepper to taste
  • 1/4 cup bread crumbs


Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
  2. Sauté Onions: In a large pan, heat olive oil over medium heat. Add the sliced onions and sauté for 3-4 minutes until they turn translucent and softened.
  3. Add Garlic: Stir the minced garlic into the pan and cook for an additional minute until fragrant. Remove the pan from heat.
  4. First Layer: In a 9×13-inch baking dish, arrange half of the zucchini slices in an even layer, followed by half of the tomato slices. Sprinkle with oregano, basil, salt, and pepper to season.
  5. Add Onion, Garlic, and Cheese: Spread half of the sautéed onion and garlic mixture over the tomato layer. Then, evenly sprinkle half of the mozzarella and Parmesan cheeses on top.
  6. Repeat Layers: Repeat the layering process with the remaining zucchini, tomatoes, onion and garlic mixture, and cheeses.
  7. Prepare Topping: Combine breadcrumbs with melted butter in a small bowl, then sprinkle this mixture evenly over the top of the casserole to create a crispy crust.
  8. Bake Covered: Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes to allow the vegetables to cook through.
  9. Bake Uncovered: Remove the foil and bake for an additional 15-20 minutes until the top is golden brown and bubbly, and the vegetables are tender.
  10. Cool and Serve: Let the casserole cool slightly before serving to allow the flavors to meld. Enjoy your warm, comforting dish!

Notes

  • For a gluten-free version, substitute bread crumbs with gluten-free bread crumbs.
  • You can add other vegetables like bell peppers or mushrooms for extra flavor.
  • Use fresh herbs if available for a more vibrant taste.
  • Letting the casserole rest before serving helps it set and makes it easier to cut.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven.
