Description

This Cheesy Zucchini Casserole is a comforting and flavorful baked dish featuring tender zucchini slices, sautéed onions and garlic, and a blend of cheeses bound together with eggs and cream. Enhanced with aromatic herbs and a crispy breadcrumb topping, it makes a perfect side or a light main course that is both satisfying and easy to prepare.


Ingredients

Scale

Vegetables

  • 4 medium zucchinis, sliced
  • 1 onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tablespoon chopped fresh basil, for garnish
  • 1 teaspoon salt

Cheese and Dairy

  • 1/2 cup grated Parmesan cheese
  • 1 1/2 cups shredded mozzarella cheese (divided)
  • 1/2 cup heavy cream
  • 2 large eggs, beaten

Dry Ingredients and Seasoning

  • 1 cup breadcrumbs
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon dried thyme
  • 1/4 teaspoon dried oregano
  • 2 tablespoons olive oil


Instructions

  1. Preheat 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 with salt. Let them sit for 15 minutes to draw out excess moisture, then pat them dry thoroughly with a paper towel.
  3. Sauté Aromatics: Heat olive oil in a skillet over medium heat and sauté the finely chopped onion and minced garlic until the onion is translucent, approximately 5 minutes.
  4. Mix Ingredients: In a large bowl, combine the sautéed onion and garlic, dried and patted zucchini slices, breadcrumbs, black pepper, dried thyme, dried oregano, Parmesan cheese, 1 cup of shredded mozzarella, heavy cream, and beaten eggs. Mix well until evenly combined.
  5. Assemble Casserole: Transfer the zucchini mixture into a greased 9×13-inch baking dish, spreading it out evenly.
  6. Add Topping: Sprinkle the remaining 1/2 cup of shredded mozzarella cheese evenly over the top of the casserole mixture.
  7. Bake: Place the casserole in the preheated oven and bake for 25 to 30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
  8. Garnish and Serve: Allow the casserole to cool slightly for a few minutes, then garnish with fresh chopped basil. Serve warm and enjoy.

Notes

  • Patting the zucchini dry after salting is essential to prevent the casserole from becoming watery.
  • Fresh herbs like basil add a bright finish but can be substituted with parsley or thyme if unavailable.
  • For a lower-fat version, substitute heavy cream with half-and-half or milk, though the texture may be less rich.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven for best texture.
