Easy Cheesy Potato Casserole (Aka:the Grandchildren's Favorite R

• 2 (10 3/4 ounce) cans cream of mushroom soup
• 2 cups shredded cheddar cheese
• 12 onion, chopped finely
• 2 cups sour cream
• 2 lbs frozen shredded hash browns, thawed (The Ore-Ida package is 30 oz., We buy that, as it's 1 lb 14 oz and it works fine)
• 12-34 cup grated parmesan cheese

1. In a large bowl mix soup and cheese.
2. Add onion and sour cream.
3. Blend together.
4. Fold in thawed potatoes.
5. Spread into a greased 9x13" baking dish.
6. Sprinkle grated parmesan cheese on top (My mom and I like to do a generous topping of parmesan, but a sprinkling will do as well).
7. Bake at 350 degrees for 1 hour or until lightly browned on top.
