Preheat your oven to 350 degrees. While your oven is heating up, mix together the butter, cream of chicken soup, sour cream, onion, cheese and pepper until well blended. Add your hash browns and mix well. I microwaved my hash browns for about 2 minutes before adding to the wet mixture.

Spoon into a 9x13 pan that has been sprayed with Pam or other cooking spray. Bake uncovered at 350 for 45 minutes.
