Description

This hearty and delicious zucchini casserole combines fresh summer zucchini with creamy cheese and a golden, crunchy topping. It’s the perfect way to use up abundant zucchini from your garden while creating a comforting side dish that pairs beautifully with grilled chicken, beef, or fish. The combination of cheddar and Parmesan cheeses creates a rich, savory flavor that even vegetable-reluctant family members will love.


Ingredients

Scale
  • 4 medium zucchinis, sliced
  • 1 cup shredded cheddar cheese
  • 1 cup breadcrumbs
  • 1/2 cup grated Parmesan cheese
  • 1 onion, chopped
  • 2 cloves garlic, minced
  • 3 large eggs
  • 1/2 cup milk
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons olive oil
  • Fresh parsley for garnish (optional)

Instructions

  1. Preheat oven to 375°F (190°C).
  2. In a large skillet, heat olive oil over medium heat. Add the chopped onion and minced garlic, sautéing for 3-4 minutes until the onion is translucent.
  3. In a large bowl, combine the sliced zucchinis, sautéed onion and garlic, shredded cheddar cheese, breadcrumbs, grated Parmesan cheese, eggs, milk, oregano, salt, and black pepper. Mix well until all ingredients are evenly combined.
  4. Transfer the zucchini mixture into a greased 9×13 inch baking dish, spreading it out evenly.
  5. Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the casserole is set.
  6. Remove from the oven and let it cool for a few minutes before serving. Garnish with fresh parsley if desired.

Notes

For best results, slice zucchini into uniform 1/4-inch rounds. If your zucchini are very large or watery, consider salting the slices and letting them drain for 15 minutes before using. You can substitute the breadcrumbs with crushed crackers or panko for extra crunch. This casserole can be assembled ahead of time and refrigerated for up to 24 hours before baking.
