Preheat your oven to 375°F (190°C) and grease a 9x13-inch casserole dish with butter or nonstick spray.
Wash and thinly slice the yellow squash and zucchini into round coins about 1/4 inch thick.
Place the sliced squash and zucchini in a large bowl. Sprinkle with 1 teaspoon of salt, toss, and set aside for 10 minutes. This will help draw out excess moisture.
While the squash rests, heat the olive oil in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes until softened. Stir in the minced garlic and cook for an additional 1-2 minutes. Remove from heat.
Pat the squash and zucchini dry with paper towels to remove excess moisture. Add them to the skillet with the onion-garlic mixture.
Mix together the shredded cheddar cheese, grated Parmesan cheese, sour cream, beaten egg, black pepper, and dried thyme in a medium bowl. Stir until smooth.
Add the cheese mixture to the skillet with the squash mixture, stirring gently until everything is evenly combined. Transfer this mixture to the prepared casserole dish.
In a small bowl, combine the panko breadcrumbs and melted butter. Sprinkle this mixture evenly over the top of the casserole.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbling.
Remove the casserole from the oven, let it cool slightly, and serve warm. Enjoy your Two Cheese Squash Casserole!
