Ingredients
- 4 cups zucchini, thinly sliced
- 2 cups sweet corn kernels (fresh or frozen)
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 cup shredded cheddar cheese
- 1/2 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup sour cream
- 1/2 cup mayonnaise
- 1 large egg, lightly beaten
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried oregano
- 1/2 teaspoon dried basil
- 1/2 cup breadcrumbs
- 2 tablespoons melted butter
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray.
2. Prepare the Vegetables
In a large skillet, sauté the chopped onion and minced garlic over medium heat until softened, about 3-4 minutes. Add the sliced zucchini and cook for an additional 5 minutes, stirring occasionally, until the zucchini is tender but not mushy. Stir in the corn kernels and cook for another 2 minutes. Remove from heat and set aside.
3. Mix the Cheese Sauce
In a large bowl, combine the shredded cheddar cheese, mozzarella cheese, grated Parmesan cheese, sour cream, mayonnaise, beaten egg, salt, black pepper, dried oregano, and dried basil. Mix well until all ingredients are fully incorporated.
4. Combine Vegetables and Cheese Sauce
Add the sautéed zucchini and corn mixture to the cheese sauce. Stir until the vegetables are evenly coated with the sauce.
5. Assemble the Casserole
Transfer the mixture to the prepared baking dish, spreading it out evenly. In a small bowl, mix the breadcrumbs with the melted butter and sprinkle this mixture evenly over the top of the casserole.
6. Bake
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the top is golden brown and crispy.
7. Serve
Allow the casserole to cool for a few minutes before serving. Garnish with fresh herbs if desired.
Expert Tips
- Use Fresh Ingredients: For the best flavor, use fresh zucchini and corn. If fresh corn isn’t available, frozen corn works well too.
- Add a Crunchy Topping: For extra texture, consider adding crushed crackers or panko breadcrumbs to the topping.
- Make Ahead: You can assemble the casserole ahead of time and refrigerate it until ready to bake. Just add a few extra minutes to the baking time if baking straight from the fridge.
- Customize with Cheese: Feel free to experiment with different types of cheese, such as pepper jack for a spicy kick or Swiss for a nutty flavor.
