Ingredients

Scale
  • 1 (30 oz) bag frozen shredded hash browns, do not thaw
  • 1 (10.5 oz) can cream of chicken soup
  • 1 (16 oz) container sour cream
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 small yellow onion, finely diced
  • 2 cups shredded sharp cheddar cheese, divided
  • 1 cup shredded Monterey Jack or Colby Jack cheese
  • 1 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon salt
  • 2 cups crushed cornflakes or crispy fried onions for topping, optional

Instructions

  1. Lightly grease the inside of a 6-quart or larger slow cooker with butter or non-stick spray.
  2. In a large mixing bowl, combine the cream soup, sour cream, melted butter, diced onion, garlic powder, smoked paprika, pepper, and salt. Stir until smooth.
  3. Add the frozen hash browns, 1 1/2 cups of the cheddar cheese, and all of the Monterey Jack cheese to the bowl. Gently fold everything together until the potatoes are coated.
  4. Pour the mixture into the prepared slow cooker and spread into an even layer. Cover and cook on LOW for 3 to 4 hours.
  5. About 30 minutes before serving, sprinkle the remaining 1/2 cup of cheddar cheese and the optional topping evenly over the casserole. Re-cover and cook for the final 30 minutes, until the cheese is melted and the casserole is bubbly.

Notes

Do not thaw the hash browns. Cook only on the LOW setting to prevent the dairy from separating. For a vegetarian version, use cream of mushroom soup. To make ahead, assemble the casserole (without final topping) in the slow cooker insert, cover, and refrigerate overnight. Cook the next day, adding 30-60 extra minutes.
