Make this easy pierogi casserole for a hearty, satisfying dinner that uses frozen pierogi and kielbasa in a slow cooker for minimal effort.

Ingredients

Scale
  • 1 (12 ounce) package smoked kielbasa sausage, sliced
  • 1 (16 ounce) package frozen potato and cheese pierogi
  • 1 (10.5 ounce) can condensed cream of chicken soup
  • 1 cup sour cream
  • 1/2 cup milk
  • 1 cup shredded cheddar cheese, divided
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 1/2 cup chopped onion (optional)
  • 2 slices bacon, cooked and crumbled (optional)

Instructions

  1. Place the sliced kielbasa and frozen pierogi into the basin of your slow cooker. If using, add the chopped onion.
  2. In a separate bowl, whisk together the cream of chicken soup, sour cream, milk, garlic powder, and pepper until smooth.
  3. Pour the sour cream mixture evenly over the pierogi and kielbasa in the slow cooker. Stir gently to coat everything.
  4. Sprinkle half of the shredded cheddar cheese (1/2 cup) over the top of the mixture.
  5. Cover the slow cooker and cook on low for 4 to 5 hours, or on high for 2 to 3 hours, until the pierogi are tender.
  6. About 15 minutes before serving, remove the lid and sprinkle the remaining 1/2 cup of cheddar cheese over the top. Cover and cook until the cheese is melted and bubbly.
  7. If using, sprinkle crumbled bacon over the top before serving. Serve this comforting Polish food hot.

Notes

  • You can substitute chicken or turkey sausage for kielbasa if desired.
  • For a crispier top, transfer the mixture to an oven-safe dish after slow cooking and bake at 375°F for 10 minutes until the cheese browns.
  • This recipe works well as a potluck casserole idea or game day food.
