Cheesy Hashbrown Casserole

Preheat oven to 350°F. Spray a 13x9-inch baking dish with cooking spray.

In a large mixing bowl, stir together, hash browns, onion, soup, sour cream, half and half, butter, Parmesan, egg, salt, pepper, granulated garlic and onion powder. Mix well, then add 3 cups cheese.

Pour evenly into baking dish. Top with remaining 1 cup cheese and sprinkle with crushed potato chips.

Bake in preheated oven for 45-50 minutes or until golden brown and bubbly. Check halfway through baking and lay aluminum foil on top to prevent the potato chips from over browning.

Let stand uncovered on the counter for 5-10 minutes then serve.
