This delicious and comforting Cheesy Delight Hash Brown Casserole is loaded with cheddar cheese, sour cream, and grated potatoes, making it the perfect addition to any family dinner or special occasion.
In a large bowl, combine the grated russet potatoes, melted unsalted butter, cream of mushroom soup, sour cream, minced yellow onion, shredded cheddar cheese, kosher salt, and coarse ground black pepper. Mix well until all the ingredients are evenly distributed.
Lightly grease a 9x13-inch baking dish and evenly spread the potato mixture into the dish.
