Ingredients Method Notes

Ingredients
  

  • 24 oz frozen pierogi
  • 1 lb kielbasa sliced
  • 1 cup sour cream
  • 1 medium onion chopped
  • 10.5 oz condensed cream of mushroom soup
  • 2 cups shredded cheddar cheese
  • 2 tbsp butter melted
  • 1 tsp salt
  • 1 tsp pepper
  • 1/4 cup chopped chives optional

Method
 

  1. Spray the inside of the crockpot with non-stick spray or insert a slow cooker liner.
  2. Layer half the frozen pierogi evenly across the bottom of the crockpot.
  3. Top with half the sliced kielbasa and half the chopped onion.
  4. In a bowl, whisk together sour cream, cream of mushroom soup, and melted butter.
  5. Spread half the creamy mixture over the layered pierogi and kielbasa.
  6. Repeat layers with remaining pierogi, kielbasa, onion, and sauce.
  7. Cover and cook on low for 4–5 hours.
  8. Sprinkle shredded cheddar cheese over the top during the last 15–30 minutes of cooking.
  9. Serve warm and garnish with chopped chives if desired.

Notes

Check pierogies at the minimum cook time to prevent them from becoming mushy. Freshly shredded cheese melts best.
