Ingredients

• 4 medium (sliced into rounds) yellow squash
• 1.5 cups (fresh, frozen, or canned and drained) corn kernels
• 1 medium (diced) onion
• 4 tablespoons butter
• 2 cloves (minced) garlic
• 2 large (beaten) eggs
• 1 cup sour cream
• 1 cup (shredded) cheddar cheese
• 1 cup (grated) parmesan cheese
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 0.75 cup bread crumbs
• 1 tablespoon olive oil

Directions

Step 1

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

Step 2

In a large skillet, melt 2 tablespoons of the butter over medium heat. Add the yellow squash and onion, and cook for 5-7 minutes until softened. Add the minced garlic and cook for an additional 30 seconds. Remove from heat and let cool slightly.

Step 3

In a large bowl, whisk together the beaten eggs and sour cream. Stir in the cheddar cheese, parmesan cheese, salt, and black pepper.

Step 4

Fold the cooked squash mixture and corn kernels into the egg mixture until well combined.

Step 5

Transfer the mixture into the prepared baking dish, spreading it out evenly.

Step 6

In a small bowl, mix together the bread crumbs and remaining 2 tablespoons of melted butter. Drizzle with olive oil and stir until the crumbs are lightly coated. Sprinkle the bread crumb mixture evenly over the casserole.

Step 7

Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 8

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