Ingredients

Scale
  • 1 (24 ounce) package frozen potato and cheese pierogi
  • 1 (12-14 ounce) package smoked kielbasa sausage, sliced
  • 1 (10.5 ounce) can condensed cream of cheddar soup
  • 1/2 cup milk
  • 1/2 cup sour cream
  • 1 cup shredded cheddar cheese, divided
  • 1/4 cup chopped green onion
  • 1/4 teaspoon black pepper

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. Arrange the frozen pierogi in a single layer in the prepared baking dish.
  3. Scatter the sliced kielbasa evenly over the pierogi layer.
  4. In a medium bowl, whisk together the condensed cream of cheddar soup, milk, and sour cream until smooth.
  5. Stir in 3/4 cup of the shredded cheddar cheese and the black pepper into the soup mixture.
  6. Pour the cheese sauce evenly over the pierogi and sausage layers.
  7. Bake for 25 to 30 minutes, or until the casserole is bubbly and heated through.
  8. Remove the dish from the oven and sprinkle the remaining 1/4 cup of shredded cheddar cheese and the chopped green onion over the top.
  9. Bake for an additional 5 minutes, or until the cheese is melted and lightly golden.
  10. Let the cheesy pierogi bake rest for 5 minutes before you serve it.

Notes

  • You can substitute smoked sausage for kielbasa if needed.
  • For a richer flavor, use cream of mushroom soup instead of cheddar soup.
  • If you prefer a slow cooker method, combine all ingredients except the top layer of cheese, cook on low for 4 hours, then top with cheese and cook on high for 15 minutes until melted.
