Ingredients

Scale
  • 1 (30 oz) bag frozen shredded hash browns, thawed
  • 1 can (10.5 oz) condensed cream of chicken soup
  • 1 cup sour cream
  • 1/2 cup unsalted butter, melted
  • 1 small yellow onion, finely diced
  • 2 cups shredded sharp cheddar cheese, divided
  • 1 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon salt
  • 1 cup crushed cornflakes or crispy fried onions

Instructions

  1. Lightly grease the inside of a 6-quart or larger slow cooker with butter or cooking spray.
  2. In a large mixing bowl, combine the thawed hash browns, cream soup, sour cream, melted butter, diced onion, 1 1/2 cups of the cheddar cheese, garlic powder, smoked paprika, pepper, and salt. Mix thoroughly until evenly coated.
  3. Spoon the mixture into the prepared slow cooker and spread into an even layer.
  4. Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
  5. Cover and cook on LOW for 3 to 4 hours, until the edges are bubbly and the center is hot.
  6. In the last 30 minutes of cooking, sprinkle the crushed cornflakes or fried onions evenly over the top. Re-cover and continue cooking for 30 minutes.
  7. Serve directly from the slow cooker.

Notes

For a make-ahead version, assemble the casserole (minus the topping) up to 24 hours in advance. Store covered in the refrigerator, then cook as directed, adding an extra 30 minutes to the cook time. For a vegetarian option, use cream of mushroom soup. Thawing the hash browns is crucial to prevent a soggy casserole.
