Ingredients

Scale

1 pound kielbasa sausage, sliced
1 (16 oz) bag frozen pierogis (cheese and potato variety)
2 cups shredded sharp cheddar cheese
1 cup sour cream
1 can (10.5 oz) cream of mushroom soup (or use a cream of chicken soup alternative)
1 medium onion, diced
2 tablespoons butter
1 teaspoon garlic powder
Salt and pepper, to taste
Fresh parsley or chives for garnish (optional)

Instructions

Prep Your Ingredients: Start by slicing the kielbasa into thin rounds. Dice the onion and set both aside. You can use store-bought frozen pierogis to keep things easy, but feel free to go with homemade pierogis if you’re feeling extra ambitious!
Layer the Casserole: Grease the bottom of your slow cooker with butter or non-stick spray. Begin by placing a layer of frozen pierogis at the bottom of the crockpot. Don’t worry about thawing them — they will cook perfectly from frozen. Next, sprinkle over half of the kielbasa slices and a few spoonfuls of diced onion.
Add the Cheesy Sauce: In a separate bowl, combine the sour cream, cream of mushroom soup, garlic powder, and half of the shredded cheddar cheese. Stir until smooth, then pour this cheesy mixture over the layers in the slow cooker. Gently spread it out to cover the pierogis.
Repeat the Layers: Add another layer of frozen pierogis on top, followed by the remaining kielbasa and onions. Top it off with the remaining shredded cheese.
Slow Cook: Cover the crockpot and cook on low for 4–5 hours, or until the pierogis are tender and the casserole is bubbly and golden. If you prefer a slightly crispier top, you can remove the lid during the last 30 minutes of cooking.
Serve: Once cooked, garnish the casserole with a sprinkle of fresh parsley or chives, if desired. Serve warm, and enjoy the creamy, cheesy goodness.

Notes

This Crock Pot Cheesy Pierogi Kielbasa Casserole can be easily doubled for a larger crowd or family gatherings. Just be sure your slow cooker is large enough to handle the increased portion size.
