Ingredients You’ll Need:

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)

How to Make Crock Pot Cheesy Pierogi Kielbasa Casserole:

Step-by-Step 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.

Helpful Tips:

Customize the Sausage: If you want to add a little variety, you can swap out the kielbasa for turkey kielbasa, smoked sausage, or even a mild beef sausage. Just be sure to slice it thin so it cooks evenly with the pierogis.
Make Ahead: This casserole is ideal for prepping ahead of time. Layer everything in the crockpot the night before, then store it in the fridge overnight. In the morning, just pop it in the slow cooker and cook as usual.
For Extra Creaminess: Add an extra dollop of sour cream or a few extra handfuls of cheese toward the end of the cooking time for a richer, creamier texture.
