Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray and set aside.
Wash the yellow squash and slice them into thin, even rounds. Dice the onion into small pieces.
In a large skillet over medium heat, melt the butter. Add the sliced squash and diced onion, and sauté for about 7-8 minutes until tender. Season with salt and ground black pepper, then remove from heat.
In a large mixing bowl, whisk together the eggs, sour cream, and 1 cup of shredded cheddar cheese until fully combined.
Gently fold the cooked squash and onion mixture into the egg and cheese mixture until evenly coated.
Transfer the squash mixture into the prepared baking dish, spreading it out in an even layer.
In a small bowl, combine the bread crumbs, grated Parmesan cheese, and the remaining 0.5 cup of shredded cheddar cheese.
Sprinkle the breadcrumb mixture evenly over the squash mixture to create the topping.
Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and bubbling.
Remove from the oven and let cool slightly for 5 minutes before serving. Enjoy your Junior League Cheesy Yellow Squash!
