Ingredients

  • 1 (30 ounce) package frozen shredded hash brown potatoes, thawed (about 12 ½ cups total)
  • 1 (14 ounce) package fully-cooked polish sausage (such as Hillshire Farm Polska Kielbasa)
  • 1 ½ cups grated sharp cheddar cheese (about 6 ounces total)
  • 1 cup (8 ounces) sour cream, at room temperature
  • 1 medium onion, very finely diced
  • ¼ cup butter, melted
  • ¼ teaspoon pepper
  • ¼ teaspoon kosher salt
  • 1 (10.5 ounce) can condensed cream of chicken soup (NOT diluted)
  • Optional garnish: chopped fresh herbs or sliced green onions

Instructions

  • Preheat oven to 350°F (180°C). Grease a 13 x 9-inch baking dish and set aside.
  • Cut sausage into slices, and then into quarters (so that you have small bite-sized pieces).
  • In a large mixing bowl, stir together all of the ingredients until completely combined.
  • Transfer the mixture to the prepared baking dish.
  • Bake, uncovered, for about 40 minutes (or until hot, bubbly, and lightly browned on top).

Notes

  • Add sautéed vegetables, such as bell peppers, tomatoes, or mushroom.
  • Instead of cheddar cheese, try other good melting cheeses such as Colby, Monterey Jack, Pepper Jack, Colby Jack, Gouda, or Velveeta.
  • Cooking for a Smaller Family? Cut all of the ingredients in half and bake the casserole in an 8-inch square dish.
  • Instead of kielbasa, use cooked bacon, chicken, turkey or diced ham. You can also use a different kind of cooked sausage, such as breakfast sausage, Italian sausage, or even hotdogs!
  • Find your largest bowl for mixing the ingredients!
  • Dice the onion into very small pieces so that it softens and becomes tender while the casserole bakes.
  • When possible, use a block of sharp cheddar cheese that you grate by hand, rather than a package of pre-shredded cheese. The hand-grated variety melts smoother into the casserole.
  • Allow the sour cream to come to room temperature. Very cold sour cream has a tendency to curdle or separate when heated quickly.
  • Garnish with sliced green onion or fresh herbs such as parsley, chives, basil or thyme.
