2 20 oz packages refrigerated shredded hash browns Or one 32 oz frozen hash browns, thawed
1 medium onion peeled and grated
1 10 3/4 oz can cream of celery soup
1 8 oz container sour cream
1 cup half and half or heavy cream
1/2 cup butter melted
1/3 cup grated Parmesan cheese
1 large egg beaten
1 tsp salt
1 tsp black pepper
1 tsp granulated garlic or garlic powder
4 cups shredded colby cheese divided
1 cup crushed potato chips

Preheat oven to 350°F. Spray a 13 x 9 inch baking dish with cooking spray.
In a large mixing bowl, mix together, hash browns, onion, soup, sour cream half and half, butter, Parmesan, egg, salt, pepper and garlic. Mix well, then add 3 cups cheese.
Pour evenly into baking dish. Top with remaining 1 cup cheese and sprinkle with crush potato chips.
Bake for 45-50 minutes or until golden and bubbly. Check halfway through baking and lay foil on top, if needed to prevent the chips from over browning.
Let stand for 5-10 minutes then serve.

This entire dish can be assembled, covered and chilled overnight before baking. In fact, it heightens the flavor. Allow it to sit on the counter for 20 minutes or so, to warm to room temperature before baking.
