How to Make Tom's Hash Browns Casserole

Preheat oven to 350°F (175°C).
In a large bowl, combine 2 pounds frozen hash browns (thawed), 1 (10.75 ounce) can condensed cream of mushroom soup, 1 cup milk, 1/2 cup shredded cheddar cheese, 1/4 cup chopped onion, 1 teaspoon salt, and 1/2 teaspoon black pepper.
Pour mixture into a lightly buttered 9x13 inch casserole dish.
Sprinkle 1/2 cup grated Parmesan cheese evenly over the top.
Bake uncovered for 50-60 minutes, or until golden brown and heated through. If the Parmesan cheese starts to brown too quickly, loosely cover the casserole with foil for the remaining baking time.
Let stand for 10 minutes before serving. Enjoy!
