I believe people refer to these as "funeral potatoes" cause it's what people bring to a funeral. I call them my "mom's potatoes". This recipe is just straight from a handwritten recipe card and I ate them all the time growing up.
Directions:
32oz (alb) bag OreIda cube hash browns (take out 1 hour ahead of time to start to defrost)
1 pint sour cream
1 small/medium yellow onion, finely chopped
1 can cream of chicken soup
1 bag shredded sharp cheddar cheese
3/4 cup melted butter (1/4 in recipe, 1/2 in topping)
2 cups cornflake crumbs
Mix together hash browns, sour cream, onion, soup, cheese and 1/4 cup butter in a large bowl. Spread in a large baking dish.
Mix cornflakes and 1/2 cup melted butter, then top potatoes with it.
Bake at 375 degrees for 1 hour.
