Ingredients
  

Main Ingredients
  • 1 lb smoked kielbasa sausage, sliced into ½-inch pieces Use fully cooked, hardwood-smoked kielbasa for best results.
  • 1 bag (32 oz) frozen diced hash brown potatoes, thawed Use coarse-cut hash browns for a sturdier bite.
  • 1 can (10.5 oz) cream of chicken soup Can also use cream of mushroom soup.
  • 1 cup sour cream Full-fat sour cream is recommended for richness.
  • 2 cups shredded cheddar cheese (divided) Use sharp or extra-sharp cheddar for maximum flavor.
  • ½ cup chopped green onions Can substitute with sautéed white onion.
  • ½ teaspoon garlic powder
  • ½ teaspoon black pepper
  • ½ teaspoon paprika
  • 2 tablespoons butter, melted
  • 1 cup crushed cornflakes or Ritz crackers (optional for topping) For a crunchy topping.

Method
 

Preparation
  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 shredded cheddar, chopped green onions, garlic powder, black pepper, and paprika. Mix until smooth.
  3. Stir the thawed hash brown potatoes into the creamy mixture until evenly coated.
  4. Fold in the sliced kielbasa until evenly distributed.
  5. Spread the mixture into the greased baking dish, leveling the top.
  6. Sprinkle the remaining ½ cup cheddar over the top. If using, mix melted butter with crushed cornflakes or Ritz crackers and scatter on top.
  7. Bake uncovered for 40–45 minutes, or until bubbly and golden brown.
  8. Let the casserole rest for 5 minutes before serving.

Notes

For variations, you can add vegetables like peas or substitute the sausage with turkey or ham. To prevent a watery casserole, ensure hash browns are fully thawed and squeezed dry.
