Ingredients

• 4 medium zucchini or yellow squash
• 2 tablespoons butter
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup sour cream
• 1 cup shredded cheddar cheese
• 1 cup grated Parmesan cheese
• 1 egg, lightly beaten
• 1 cup Italian-seasoned breadcrumbs
• 2 tablespoons olive oil
• 1 teaspoon salt
• 0.5 teaspoons black pepper

Directions

Step 1

Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set it aside.

Step 2

Wash and slice the zucchini or squash into 1/4-inch thick rounds.

Step 3

In a large skillet, melt butter over medium heat. Add the chopped onion and sauté until softened, about 3-4 minutes. Add the minced garlic and cook for 1 more minute.

Step 4

Add the zucchini or squash slices to the skillet and cook for 5-7 minutes, stirring occasionally, until slightly softened. Remove the skillet from heat.

Step 5

In a large mixing bowl, combine the sour cream, shredded cheddar cheese, grated Parmesan cheese, beaten egg, salt, and black pepper. Stir until fully mixed.

Step 6

Gently fold the cooked zucchini or squash mixture into the sour cream and cheese mixture until evenly coated.

Step 7

Pour the mixture into the prepared baking dish, spreading it evenly with a spatula.

Step 8

In a small bowl, mix the breadcrumbs and olive oil together until the breadcrumbs are moistened. Sprinkle this mixture evenly over the top of the casserole.

Step 9

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 10

Remove from the oven and let it cool for 5 minutes before serving. Enjoy!
