Description

A comforting, flavorful casserole made with fresh summer vegetables like zucchini, corn, tomatoes, and bell peppers, topped with a melty layer of cheese and crispy breadcrumbs.


Ingredients

1 tablespoon olive oil

1/2 cup onion, diced

2 cloves garlic, minced

1 zucchini, chopped

1/2 cup tomatoes, chopped

1/2 cup corn kernels

1/2 cup red bell pepper, diced

1 teaspoon dried oregano

1/2 teaspoon salt

1/4 teaspoon black pepper

3/4 cup shredded cheddar cheese (or vegan cheese)

1/4 cup grated Parmesan (or nutritional yeast for vegan)

2 large eggs (or flax eggs for vegan)

1/4 cup milk of choice (dairy or plant-based)

1/4 cup breadcrumbs (gluten-free if needed)

2 tablespoons fresh parsley, chopped


Instructions

  1. Preheat the oven to 375°F (190°C). Lightly grease an 8x8-inch baking dish.
  2. Heat olive oil in a large skillet over medium heat. Add the onion and garlic, sautéing for about 3 minutes, until softened.
  3. Add the zucchini, tomatoes, corn, and bell pepper to the skillet. Cook for another 5-7 minutes, stirring occasionally, until the vegetables are tender.
  4. Stir in the dried oregano, salt, and pepper. Remove the skillet from the heat.
  5. In a separate large bowl, whisk together the eggs and milk. Stir in the shredded cheddar and Parmesan.
  6. Add the sautéed vegetables into the egg and cheese mixture, mixing well to combine.
  7. Transfer the vegetable and egg mixture into the prepared baking dish, spreading it out evenly.
  8. Sprinkle breadcrumbs evenly over the top of the casserole.
  9. Bake for 25-30 minutes, or until the casserole is set and golden brown on top.
  10. Let the casserole cool for 5 minutes before serving. Garnish with fresh parsley and serve.

Notes

Vegan: Replace eggs with flax eggs and use vegan cheese and nutritional yeast instead of Parmesan.

Cheese options: Use any cheese that melts well, like mozzarella or Monterey Jack.

Gluten-free: Use gluten-free breadcrumbs for a gluten-free option.

Storage: Leftovers can be stored in the fridge for up to 3 days.

Reheating: Reheat in the oven at 350°F (175°C) for 10-15 minutes or microwave individual servings for 1-2 minutes.
