1 cup crushed cornflakes or breadcrumbs (for crispy topping)
Instructions
Preheat oven to 350°F (175°C).
In a large mixing bowl, combine thawed hashbrowns, sour cream, cream of chicken soup, shredded cheddar cheese, diced onion, garlic powder, salt, and pepper. Stir gently but thoroughly.
Pour mixture into a greased 9×13 inch baking dish and spread evenly.
In a small bowl, mix melted butter with crushed cornflakes or breadcrumbs. Sprinkle evenly over casserole.
Bake uncovered for 45 minutes to 1 hour until bubbly and golden crust forms. Tent with foil if top browns too fast.
Let casserole rest for 10 minutes before serving to set and make cutting easier.
