Awesome Potato Casserole

From my friend Michelle, in a recipe exchange. She says "I could live off this stuff; It's great for potlucks, too."

• 2 Lbs Hash Brown Potatoes (thawed, if frozen)
• 1/2 cup melted butter
• 1 can cream of potato soup
• 8 oz sour cream
• 1 cup diced ham
• 2 cups shredded cheddar
• salt and pepper to taste
• 1/2 cup chopped onions, optional

Mix all ingredients in a gigantic bowl, transfer to a 13X9 casserole dish, add whatever topping you wish, Cover and Bake at 350 for 45 minutes.

Topping ideas: 2 cups corn flakes mixed with 1/4 cup butter works, but I usually just add about 1 c cheese when there's only 10 minutes left on the timer.
