Ingredients

Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. - Cook the Squash and Onion
In a large skillet, melt the butter over medium heat. Add the sliced squash and chopped onion. Sauté until tender, about 8–10 minutes. Drain any excess liquid. - Mix the Filling
In a large bowl, combine the cooked squash and onions with sour cream, shredded cheddar cheese, egg, salt, pepper, and garlic powder. Stir gently until everything is well combined. - Prepare the Topping
Crush the buttery crackers and mix them with a tablespoon of melted butter. - Assemble the Casserole
Pour the squash mixture into the prepared baking dish. Sprinkle the cracker topping evenly over the top. For extra flavor, add grated Parmesan cheese. - Bake the Casserole
Bake uncovered for 25–30 minutes, or until the topping is golden brown and the casserole is bubbly. - Cool and Serve
Let the casserole rest for a few minutes before serving to allow it to set. Enjoy warm!
