Equipment

Ingredients
  

  • 26 ounces hashbrowns ((1 bag))
  • 2 cups cheese
  • ½ cup onion (diced)
  • 1 cup sour cream
  • 1 can cream of chicken soup (about 10.5 ounces)
  • ¼ cup water
  • 1 teaspoon salt
  • ½ teaspoon pepper

Instructions
 

  • Combine the hashbrowns (see note) with 1 cup of the cheese and the onion.
  • In a seperate bowl, mix together sour cream, cream of chicken soup, water, salt, and pepper.
  • Combine the hashbrown mixture with the sour cream mixture.
  • Line or spray the slow cooker liner.
  • Pour in the hashbrown mixture and evenly distribute it.
  • Top with the remaining cup of cheese.
  • Cook on low for three hours or until the center registers 208º on an instant read thermometer.

Notes

Hashbrown Options:
  • You can use frozen or thawed hashbrowns. 
Flavor Variations: 
  • While the cream of chicken soup is traditional, you can switch things up by using a cream of mushroom soup or cream of celery soup.
  • Sprinkle in red pepper flakes, garlic powder, or cayenne pepper for a spicier kick. And while the real ingredients are always best, try using onion powder if you don't have any yellow onion.
Protein Additions:
  • For a heartier dish, mix in cooked and crumbled sausage or bacon to the casserole mixture. Cooked chicken or ham can also be used.
Extra Cheese Hack:
  • Mix your uncooked hashbrowns with some cream cheese for added cheesiness.
Veggie Boost:
  • For added nutrition, mix in chopped red bell pepper, mushrooms, or spinach to the casserole mixture.
Serving Suggestions:
  • This versatile casserole works for any meal! For breakfast, pair it with scrambled eggs, bacon, and fresh fruit. As a side dish, serve it alongside your favorite protein with vegetables like green beans or a fresh salad. You can also enjoy it as a standalone dish topped with green onions, crispy bacon, or a dollop of sour cream.
Storage Tips:
  • Store leftover casserole in the refrigerator for up to 4 days in an airtight container or covered with plastic wrap.
  • For longer storage, freeze portions for up to 3 months.
