Ingredients

Scale

Vegetables

  • 4 medium Zucchini (fresh and firm)

Sauces & Oils

  • 1 cup Marinara Sauce (rich and tangy)
  • 1 tablespoon Olive Oil

Cheeses

  • 1 cup Parmesan Cheese (freshly grated)
  • 1 cup Mozzarella Cheese

Binding and Flavoring

  • 2 large Eggs
  • 1 tablespoon Garlic (minced)
  • 1 tablespoon Italian Herbs (oregano and basil)
  • 1 teaspoon Salt
  • 1 teaspoon Pepper

Toppings and Garnish

  • 1 cup Breadcrumbs
  • 1 bunch Fresh Basil Leaves (for garnish)

Instructions

  1. Preheat the oven: Start by preheating your oven to 375°F to ensure it reaches the perfect temperature for baking.
  2. Slice the zucchini: Thinly slice the 4 medium zucchinis into 1/4-inch thick rounds, providing even layers for the casserole.
  3. Prepare the zucchini: In a large bowl, drizzle the zucchini slices with 1 tablespoon of olive oil. Add minced garlic, Italian herbs, salt, and pepper, then toss everything together to evenly coat and infuse the zucchini with flavor.
  4. Layer the casserole: Grease a 9×13-inch baking dish, then spoon one-third of the marinara sauce evenly on the bottom. Arrange half of the zucchini slices over the sauce. Sprinkle with ½ cup Parmesan cheese and 1 cup mozzarella cheese. Repeat the layering process starting with the remaining marinara sauce, then zucchini slices, and cheeses.
  5. Bake the casserole: Place the assembled casserole in the preheated oven and bake at 375°F for 25–30 minutes, or until the cheese topping is golden brown and bubbly, indicating it’s perfectly cooked.
  6. Rest and garnish: Once baked, allow the casserole to rest for 5 minutes to set for easy slicing. Garnish the top with fresh basil leaves before serving for a vibrant, fresh finish.

Notes

  • Use fresh and firm zucchinis for the best texture in the casserole.
  • Freshly grated Parmesan cheese enhances flavor better than pre-grated options.
  • The eggs help bind the casserole layers for cleaner slices.
  • Letting the casserole rest after baking ensures it holds together well when sliced.
  • For a crunchier topping, lightly toast breadcrumbs before sprinkling on top.
  • Feel free to customize with additional herbs like thyme or rosemary for variation.
