Ingredients

Scale
  • 1 (30 oz) bag frozen shredded hash browns, do not thaw
  • 1 (10.5 oz) can condensed cream of chicken soup
  • 1 (16 oz) container 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
  • 1/2 teaspoon salt, or to taste
  • 1 cup crushed cornflakes or crispy fried onions, optional for topping

Instructions

  1. Lightly grease the inside of a 4 to 6 quart slow cooker with butter or non-stick spray.
  2. In a large mixing bowl, combine the condensed soup, sour cream, melted butter, diced onion, garlic powder, smoked paprika, black pepper, and salt. Stir until smooth.
  3. Add the frozen hash browns and 1 1/2 cups of the shredded cheddar cheese to the bowl. Gently fold everything together until the potatoes are evenly coated.
  4. Pour the mixture into the prepared slow cooker and spread into an even layer.
  5. Cover and cook on LOW for 3 to 4 hours, or on HIGH for 1.5 to 2 hours, until the edges are bubbly and the potatoes are tender.
  6. About 15 minutes before serving, sprinkle the remaining 1/2 cup of cheese (and the optional topping, if using) evenly over the casserole. Re-cover and let sit until the cheese melts.

Notes

For a vegetarian version, use cream of mushroom or celery soup. Do not thaw the hash browns, as this can make the casserole watery. Avoid stirring during cooking. Leftovers reheat well in the oven or microwave.
