Ingredients

Scale
  • 1 (12 ounce) package smoked kielbasa sausage, sliced
  • 1 (16 ounce) package frozen potato and cheese pierogi
  • 1 cup chopped onion
  • 4 tablespoons butter
  • 1 (10.5 ounce) can cream of chicken soup
  • 1/2 cup sour cream
  • 1/2 cup milk
  • 1 teaspoon dried dill weed
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 2 cups shredded cheddar cheese, divided
  • 1 cup shredded mozzarella cheese

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large skillet over medium heat, cook the sliced kielbasa until lightly browned. Remove the kielbasa with a slotted spoon and set aside.
  3. Add the chopped onion to the same skillet and cook in the remaining drippings until softened, about 5 minutes. Add the butter and let it melt.
  4. Stir in the cream of chicken soup, sour cream, milk, dill weed, garlic powder, and pepper until the mixture is smooth.
  5. Fold in one cup of the cheddar cheese, the cooked kielbasa, and the frozen pierogi into the sauce mixture. Stir gently to coat everything.
  6. Pour the pierogi mixture into the prepared baking dish, spreading it into an even layer.
  7. Top the casserole evenly with the remaining one cup of cheddar cheese and the mozzarella cheese.
  8. Bake for 25 to 30 minutes, or until the casserole is hot and bubbly and the cheese topping is melted and lightly golden brown.
  9. Let the casserole rest for 5 minutes before serving.

Notes

  • You can substitute turkey bacon or cooked chicken for the kielbasa if you prefer a different meat.
  • If you want a richer flavor, use cream of mushroom soup instead of cream of chicken soup.
  • For extra flavor, sauté the onions with 4 ounces of chopped bacon before adding the kielbasa back in.
