Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.

Step 2

Thinly slice the yellow squash into rounds and set aside.

Step 3

In a large skillet, melt 2 tablespoons of butter over medium heat. Add the chopped onion and minced garlic, cooking until softened, about 3-4 minutes.

Add the sliced yellow squash and cook for 5-7 minutes until it begins to soften. Stir in the sweet corn and remove from heat.

Step 5

In a medium mixing bowl, whisk together the sour cream, eggs, salt, black pepper, and paprika. Fold in the shredded cheddar cheese.

Step 6

Combine the sour cream mixture with the cooked squash and corn, stirring gently to evenly coat the vegetables.

Step 7

Transfer the squash and corn mixture into the prepared casserole dish, spreading it out evenly.

Step 8

In a small bowl, mix the bread crumbs, grated parmesan cheese, olive oil, and remaining 2 tablespoons of melted butter until the crumbs are evenly coated.

Step 9

Sprinkle the bread crumb mixture evenly over the top of the casserole.

Step 10

Bake uncovered in the preheated oven for 35-40 minutes, or until the topping is golden brown and crispy.
