Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.
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.
In a large bowl, whisk together the beaten eggs and sour cream. Stir in the cheddar cheese, parmesan cheese, salt, and black pepper.
Fold the cooked squash mixture and corn kernels into the egg mixture until well combined.
Transfer the mixture into the prepared baking dish, spreading it out evenly.
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.
Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
Remove from the oven and let cool for 5 minutes before serving.
