1 (2 lb.) bag frozen hash browns, thawed
1 c. sour cream
1 can cream of celery soup (or any cream soup you like)
1 c. cheese
Onion as desired (I use instant chopped)

Mix all together and place in 9x13 pan that has been sprayed with no stick. Sprinkle crumbled corn flakes or potato chips on top to cover. Bake at 350 degrees for 30 minutes or until hot and bubbly.
