Ingredients

Scale

Zucchini Preparation

  • 4 medium zucchinis, sliced
  • 1 teaspoon salt

Sautéed Aromatics

  • 2 tablespoons olive oil
  • 1 onion, finely chopped
  • 2 cloves garlic, minced

Casserole Mixture

  • 1 cup breadcrumbs
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon dried thyme
  • 1/4 teaspoon dried oregano
  • 1/2 cup grated Parmesan cheese
  • 1 1/2 cups shredded mozzarella cheese (divided: 1 cup for mixture, 1/2 cup for topping)
  • 1/2 cup heavy cream
  • 2 large eggs, beaten

Garnish

  • 1 tablespoon chopped fresh basil


Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
  2. Prepare Zucchini: Spread the sliced zucchinis on a baking sheet and sprinkle evenly with salt. Let them sit for 15 minutes to draw out excess moisture, then pat dry thoroughly with paper towels to avoid a watery casserole.
  3. Sauté Aromatics: Heat olive oil in a skillet over medium heat. Add the chopped onion and minced garlic, sautéing until the onion becomes translucent and fragrant, about 5 minutes.
  4. Mix Ingredients: In a large bowl, combine the sautéed onion and garlic with the prepared zucchini, breadcrumbs, black pepper, dried thyme, oregano, grated Parmesan cheese, 1 cup of shredded mozzarella, heavy cream, and beaten eggs. Stir well until all ingredients are evenly incorporated.
  5. Assemble Casserole: Transfer the zucchini mixture to a greased 9×13-inch baking dish. Spread it evenly to ensure consistent cooking.
  6. Add Topping: Sprinkle the remaining 1/2 cup of shredded mozzarella cheese evenly over the top for a golden, cheesy crust.
  7. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, until the top turns golden brown and the mixture is bubbling at the edges, indicating it is cooked through.
  8. Garnish and Serve: Allow the casserole to cool for a few minutes after baking. Garnish with freshly chopped basil and serve warm for the best flavor and texture.

Notes

  • Salting the zucchini helps remove excess moisture, preventing a soggy casserole.
  • Use fresh herbs like basil for a bright garnish, or substitute with parsley if unavailable.
  • For a lighter version, substitute heavy cream with half-and-half or Greek yogurt, but the texture may be slightly different.
  • This casserole can be made ahead and refrigerated before baking; just increase baking time by 5-10 minutes if baking cold.
  • Leftovers keep well in the refrigerator for up to 3 days and reheat nicely in the oven or microwave.
