There are many versions of Funeral Potatoes. Some recipes call for putting cheese (about 1 cup of Cheddar, American or whatever you like) in the potato mixture and using buttered bread crumbs for the topping.
1 1/2 lbs frozen hash brown potatoes, preferrably southern-style diced ones
1 (10 3/4 oz) can condensed cream of celery soup (or cream soup of your choice)
1 (10 3/4 oz) can condensed cream of potato soup
3/4 cup milk
1 pint sour cream
Grated parmesan cheese and butter for topping
Heat over to 350 degrees F.
Mix all the ingredients except cheese and butter, and pour into a shallow baking dish. Top generously with cheese and dot with bits of butter. Bake for 45 to 60 minutes or until bubbly and cheese is lightly browned.
Makes 6 to 8 servings.
