How to make Crockpot Pierogi Casserole with Kielbasa
Step 1:
Heat the butter in a skillet over medium heat. Add the kielbasa and onion, cooking until the onion is soft and the kielbasa is lightly browned. Add the minced garlic and cook for another minute.
Step 2:
In a medium bowl, combine the cream of mushroom soup, sour cream, milk, black pepper, and paprika. Stir until well blended.
Step 3:
Spray the crockpot with non-stick cooking spray. Layer half of the pierogies on the bottom. Top with half of the kielbasa mixture, then pour half of the sauce over the top. Repeat the layers with the remaining ingredients.
Step 4:
Sprinkle the shredded cheddar cheese evenly over the top.

Helpful Tips
- Browning the kielbasa before adding it to the crockpot enhances its flavor and adds depth to the dish. The caramelization brings out the smoky notes of the sausage.
- No need to thaw them; just layer them directly in the crockpot to save time and effort. They’ll cook perfectly in the creamy sauce.
- Ensure the sour cream, soup, and milk are well combined to create a smooth and creamy sauce. This prevents any lumps from forming.
- Incorporate vegetables like peas, carrots, or broccoli for added nutrition and color. These additions make the dish even heartier and visually appealing.
- For even cooking, layer the ingredients evenly in the crockpot. Avoid over-stacking to ensure everything cooks uniformly.
- Avoid lifting the lid while cooking to maintain the temperature and ensure consistent results. Each peek can add cooking time!
- Add extra shredded cheese on top during the last 15 minutes for a gooey, melty finish that everyone will love.
Optional Ingredients
- Paprika: Sprinkle on top for a smoky, slightly spicy flavor. Paprika also adds a pop of color to the dish.
- Green Onions: Garnish with chopped green onions for a fresh, tangy finish. They also add a nice crunch.
- Cheddar Cheese: Add an extra layer of shredded cheddar for more cheesiness and a sharper flavor.
- Vegetables: Include broccoli, peas, or diced bell peppers for added texture and nutrition. These veggies complement the pierogies and kielbasa beautifully.
- Crumbled Bacon: Sprinkle-cooked bacon on top for extra indulgence and a salty kick.
- Mustard: Stir in a teaspoon of Dijon mustard to the sauce for a tangy kick that enhances the dish’s flavor complexity.
How to Enjoy Crockpot Pierogi Casserole with Kielbasa?
For serving, always plate this dish with love. My favorite way is to garnish it with fresh parsley or green onions for a pop of color. This little touch makes it look as good as it tastes and adds a fresh note to balance the richness.
Pair this casserole with a simple green salad or steamed vegetables to balance the richness of the dish. A slice of crusty bread or a warm dinner roll is perfect for soaking up the creamy sauce, completing the meal. For an added twist, you can serve it with a dollop of sour cream on the side.
You can also serve it as part of a larger spread for gatherings or celebrations. Its hearty flavors make it a standout dish that everyone will enjoy, and the crockpot makes it easy to keep warm throughout the event. This dish always gets compliments and makes hosting stress-free.

Recipe Variations
Vegetarian Version: Swap the kielbasa for plant-based sausage and use mushroom or vegetable pierogies. It’s just as hearty and flavorful without the meat.
Spicy Kick: Add red pepper flakes or use spicy kielbasa for a bit of heat. This variation is perfect for spice lovers.
Mexican Twist: Use pepper jack cheese and add diced jalapeños for a fusion flavor. Serve with a dollop of salsa for an extra kick.
Creamy Alfredo: Replace the cream of mushroom soup with Alfredo sauce for a rich, cheesy variation. This version is ultra-creamy and indulgent.
Loaded Pierogi Casserole: Top with crumbled bacon, sour cream, and chives for a loaded baked potato feel. It’s a comforting classic reimagined.
Herb-Infused: Add fresh thyme or rosemary to the sauce for an aromatic twist that elevates the dish’s flavor profile.
How to Store
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the entire dish in the oven at 350°F (175°C) until heated through. If reheating in the oven, cover with foil to prevent drying out.
For longer storage, freeze the casserole in portions. Let it cool completely before transferring to freezer-safe containers. To reheat, thaw overnight in the refrigerator and warm in the crockpot or oven. Freezing may slightly alter the texture of the pierogies but will still taste delicious. Ensure the sauce is stirred well during reheating for the best consistency.
