Ingredients Equipment Method Notes

Ingredients
  

  • 1 pound Smoked kielbasa sausage sliced into ½-inch pieces
  • 1 bag Frozen diced hash brown potatoes 32 oz/900g, thawed
  • 1 can Cream of chicken soup 10.5 oz/295g (or use cream of mushroom)
  • 1 cup Sour cream
  • 2 cups Shredded cheddar cheese divided – use 1½ cups in the mixture and reserve ½ cup for topping
  • 1/2 cup Chopped green onions or substitute with sautéed white onions
  • 1/2 teaspoon Garlic powder
  • 1/2 teaspoon Black pepper
  • 1/2 teaspoon Paprika
  • 2 tablespoons Melted butter
  • 1 cup Crushed cornflakes or Ritz crackers Optional topping for a crunchy texture

Equipment

  • 9x13-inch baking dish
  • Large mixing bowl
  • Oven

Method
 

  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
  2. In a large mixing bowl, combine the cream of chicken soup, sour cream, 1½ cups of shredded cheddar cheese (reserve ½ cup for topping), chopped green onions, garlic powder, black pepper, and paprika. Stir until the mixture is smooth and creamy.
  3. Fold in the thawed hash brown potatoes, ensuring they are evenly coated with the creamy mixture.
  4. Gently mix in the sliced kielbasa sausage pieces so that the meat is distributed throughout the mixture.
  5. Transfer the mixture into the prepared baking dish and spread it evenly into all corners. Sprinkle the reserved shredded cheddar cheese over the top.
  6. For an extra crunchy topping, combine the melted butter with the crushed cornflakes or Ritz crackers and evenly sprinkle over the cheese layer.
  7. Bake in the preheated oven for 45-50 minutes, until the edges are bubbling and the top is golden brown.
  8. Allow the casserole to rest for 5-10 minutes before serving so that it sets and is easier to scoop.

Notes

This comforting casserole is incredibly versatile and perfect for weeknight dinners. If you don’t have kielbasa, you can substitute with Polish sausage or even sliced hot dogs, and vegetarians can skip the meat altogether. The optional crispy topping made with cornflakes or crackers adds a delightful crunch. You can also prepare the casserole mix ahead of time and refrigerate it, then bake when ready for an even easier dinner solution.
