  • 14 ounces kielbasa turkey kielbasa is my preference, but any will do
  • 32 ounces hash brown potates cut into small cubes, not shredded
  • cups shredded cheddar cheese, divided sharp cheddar works well
  • 1 cup chicken stock
  • ¼ cup powdered milk
  • tablespoon corn starch
  • ½ cup onion chopped/diced
  • 1 teaspoon garlic powder
  • ½ cup sour cream


  • defrost potatoes in refridgerator if they are frozen,
  • slice kielbasa into 1" thick coins
    14 ounces kielbasa
  • mix together chicken stock, powdered milk, and corn starch.
    1 cup chicken stock, ¼ cup powdered milk, 1½ tablespoon corn starch
  • add kielbasa, potatoes, onion, garlic powder, and 2 cups cheese to slow cooker
    14 ounces kielbasa, 32 ounces hash brown potates, 2½ cups shredded cheddar cheese, divided, ½ cup onion, 1 teaspoon garlic powder
  • pour chicken stock mixture over slow cooker contents and stir briefly to combine
  • cover and cook on low for 3-5 hours.
  • check on your dish after about 3 hours. You can tell if your casserole is ready based on the potatoes. If they are still hard or crunchy, they need to cook longer. Once they are cooked, you should serve or turn your slow cooker down to warm. Overcooked potatoes will become mushy.
  • 15 - 20 minutes prior to serving, stir in sour cream. Sprinkle remaining shredded cheese and replace slow cooker cover allowing the cheese to melt.
    2½ cups shredded cheddar cheese, divided, ½ cup sour cream


note: I use a bullion product like Better Than Bouillon to make easy stock.  
My dish is generally ready to be served after 3.5 hours of cooking time.
