This creamy, gooey hashbrown casserole is the best cheesy potato side dish for potlucks, holidays, or family dinners. You can prepare it ahead of time for easy serving.

Ingredients

Scale
  • 2 pounds frozen shredded hashbrown potatoes, thawed
  • 1 can (10.5 ounces) cream of chicken soup
  • 1 can (10.5 ounces) cream of mushroom soup
  • 1 cup sour cream
  • 1 cup milk
  • 1 cup (8 ounces) butter, melted
  • 1 small onion, finely chopped
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 cups shredded sharp cheddar cheese, divided
  • 1 cup crushed cornflakes (optional topping)

Instructions

  1. Preheat your oven to 350 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, combine the thawed hashbrown potatoes, cream of chicken soup, cream of mushroom soup, sour cream, milk, melted butter, chopped onion, salt, and pepper. Mix gently until everything is just combined. Do not overmix.
  3. Stir in 1 1/2 cups of the shredded cheddar cheese into the potato mixture.
  4. Pour the mixture evenly into the prepared baking dish.
  5. If using the topping, mix the crushed cornflakes with the remaining 1/2 cup of cheddar cheese. Sprinkle this mixture evenly over the top of the casserole.
  6. Bake for 45 to 55 minutes, or until the casserole is hot and bubbly throughout and the topping is golden brown.
  7. Let the cheesy potato casserole rest for 5 to 10 minutes before serving.

Notes

  • For make-ahead preparation, assemble the entire casserole, cover it tightly with foil, and refrigerate for up to 24 hours. When ready to bake, add 10 to 15 minutes to the baking time if baking directly from the refrigerator.
  • You can substitute cream of celery soup for one of the other soups if you prefer a different flavor base.
  • This recipe works well with frozen diced potatoes instead of shredded hashbrowns.
