Grandma Anderson'S Hashbrown Casserole - cooking recipe

Ingredients

1 kg frozen hash browns, cubed, not shredded
500 ml sour cream
2 (10 ounce) cans cream of mushroom soup
1/2 cup butter, melted
2 cups cheese, grated

1 cup parmesan cheese, to sprinkle on top

Preparation

In a very large bowl, mix the hash browns, sour cream, cream of mushroom soup, melted butter, grated cheese, and onion together.
Spread into a large 9 x 13 inch casserole dish.
Sprinkle with Parmesan cheese on top. In a pinch, you could use crushed cornflakes but you should top it with something.
