Ingredients

Scale

Main Ingredients

  • 1 package frozen pierogies (cheese-filled or potato stuffed, about 16 oz)
  • 1 lb kielbasa sausage, sliced into bite-sized pieces
  • 1 cup sour cream
  • 1 to 1 ½ cups shredded cheese (cheddar, mozzarella, or preferred type)
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • Salt and pepper to taste
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Prepare the Ingredients: Slice the kielbasa into bite-sized pieces and dice the onions and garlic. If using fresh parsley or additional veggies, chop those now so all ingredients are ready.
  2. Layer the Pierogies and Kielbasa: In your crockpot, place a layer of frozen pierogies first, then add a generous layer of kielbasa slices on top. Evenly sprinkle diced onions and garlic over these layers for extra flavor.
  3. Add Sour Cream and Cheese: Spoon dollops of sour cream across the layers, creating creamy pockets in the casserole. Then evenly sprinkle shredded cheese over the entire top layer for a gooey finish.
  4. Cook It Low and Slow: Cover the crockpot and cook on low heat for 4 to 6 hours. This allows the pierogies to soften and absorb smoky flavors from the kielbasa, while the cheese melts perfectly.
  5. Garnish and Serve: Once the cooking is complete, sprinkle freshly chopped parsley over the casserole for added color and freshness. Serve warm and enjoy.

Notes

  • Use frozen pierogies directly without thawing to maintain texture during slow cooking.
  • Layer ingredients evenly to ensure balanced flavors throughout the casserole.
  • Add cheese during the final hour of cooking to prevent sticking and allow perfect melting.
  • Do not overfill the crockpot; leave space for heat circulation to ensure even cooking.
  • Optionally, stir gently halfway through cooking to combine flavors without breaking the pierogies.
