Equipment

Ingredients
 
 

  • 30 ounces frozen shredded hashbrown potatoes
  • 10¾ ounces cream of mushroom soup canned
  • ½ cup butter melted
  • 1 cup sour cream
  • ½ cup yellow onion sliced
  • ½ teaspoon dried thyme
  • ½ teaspoon salt
  • ½ teaspoon pepper
  • 2 cups Cheddar cheese divided

Instructions
 

  • Preheat your oven to 350°F (180°C). Lightly grease a 9x13-inch baking dish to prevent sticking and make cleanup easier.
  • In a large mixing bowl, combine frozen hashbrowns, cream of mushroom soup, melted butter, sour cream, sliced onion, dried thyme, salt, pepper, and half of the shredded cheddar cheese. Mix thoroughly until the ingredients are evenly distributed, but avoid overmixing to keep the texture intact.

  • Transfer the mixture to the prepared baking dish, spreading it out evenly. Place the dish in the oven and bake uncovered for 45 minutes, or until the edges turn golden and the center is bubbling.
  • Take the casserole out of the oven and sprinkle the remaining shredded cheese over the top. Return it to the oven for another 10–15 minutes, until the cheese has melted and is bubbling. Remove from the oven, serve hot and enjoy.

Notes

  • Thaw your hashbrowns slightly: Let them sit at room temperature for 10–15 minutes so they mix easily and bake evenly.
  • Use freshly shredded cheese: Pre-shredded cheese has anti-caking agents that affect how it melts. Freshly shredded cheese gives a smoother, creamier result.
  • Add a crunchy topping: Crushed potato chips, buttered breadcrumbs, or even crushed crackers make a delicious topping. Add them before the final bake for extra texture.
  • Customize the flavors: Diced ham, crumbled bacon, or sautéed mushrooms can easily be mixed in to elevate the casserole.
  • Check for doneness: The casserole is ready when the center is hot and the edges are bubbling. A quick test with a fork ensures it’s evenly heated.
  • Lighten it up: Substitute Greek yogurt for sour cream, or use reduced-fat cheese and soup for a lower-calorie option.
  • Prevent overbaking: Cover the casserole with foil if the edges are browning too quickly.
