Ingredients

  • 450 grams 1 pound of smoked kielbasa, cut into ½-inch rounds
  • 900 grams 32 ounces of frozen diced hash brown potatoes, thawed beforehand
  • 295 grams 10.5 ounces of condensed cream of chicken soup, or substitute with cream of mushroom
  • 240 milliliters 1 cup of sour cream
  • 200 grams 2 cups of shredded cheddar cheese, separated
  • 120 milliliters ½ cup of chopped green onions or sautéed white onion
  • ½ teaspoon of ground paprika
  • ½ teaspoon of garlic powder
  • ½ teaspoon of freshly ground black pepper
  • 2 tablespoons of melted butter
  • Optional topping: 1 cup of crushed cornflakes or crushed Ritz crackers

Instructions

  • Preheat the oven to 175°C (350°F) and lightly grease a 9×13-inch baking dish.
  • In a large mixing bowl, blend the cream of chicken soup with sour cream, 1½ cups of the cheddar cheese, chopped onions, garlic powder, black pepper, and paprika. Stir until the mixture is smooth and fully combined.
  • Add the thawed hash brown potatoes to the bowl and stir until the potatoes are evenly coated in the creamy mixture.
  • Gently incorporate the kielbasa slices into the mixture, folding them in to distribute evenly.
  • Transfer the entire mixture into the prepared baking dish, spreading it out in an even layer.
  • Sprinkle the remaining ½ cup of cheddar cheese evenly over the top.
  • If using the optional topping, combine the crushed crackers or cornflakes with melted butter and scatter over the cheese layer for added crunch.
  • Bake the casserole uncovered for 40 to 45 minutes, or until it is bubbling around the edges and the top is beautifully golden.
  • Allow the dish to rest for 5 minutes before serving.
