Ingredients

Scale
  • 1 (12 ounce) package smoked kielbasa sausage, sliced
  • 1 (16 ounce) package frozen cheese pierogi, uncooked
  • 1 cup chopped onion
  • 4 tablespoons butter
  • 1/2 cup all-purpose flour
  • 2 cups chicken broth
  • 1 cup milk
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 8 ounces cream cheese, cubed
  • 2 cups shredded cheddar cheese, divided
  • 1/2 cup sour cream
  • 1/2 cup crumbled cooked bacon (optional)

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 and set it aside, leaving about one tablespoon of drippings in the skillet.
  3. Add the chopped onion to the skillet and cook until softened, about 5 minutes. Add the butter and let it melt.
  4. Whisk in the flour until smooth. Gradually whisk in the chicken broth and milk. Cook, stirring constantly, until the sauce thickens, about 5 to 7 minutes.
  5. Remove the skillet from the heat. Stir in the salt, pepper, cream cheese, and 1 1/2 cups of the shredded cheddar cheese until the cheese melts and the sauce is smooth.
  6. Gently stir in the cooked kielbasa, frozen pierogi, and sour cream until everything is coated.
  7. Pour the mixture into the prepared baking dish. Top evenly with the remaining 1/2 cup of shredded cheddar cheese and the crumbled bacon, if using.
  8. Bake for 30 to 35 minutes, or until the casserole is bubbly and the top is golden brown.
  9. Let the pierogi casserole rest for 5 minutes before you serve it.

Notes

  • You can substitute turkey bacon or cooked chicken for the kielbasa if you prefer a different meat.
  • If you want a crispier top, you can briefly place the casserole under the broiler for the last minute of cooking, watching carefully to prevent burning.
  • This dish works well using potato and cheese pierogi straight from the freezer; do not thaw them first.
