Ingredient Notes
Frozen pierogies are what make this casserole so easy. Cheese or potato pierogies are the most common and work especially well because they fit perfectly with the creamy sauce and smoky kielbasa.
Kielbasa brings a deep savory flavor and holds up well during slow cooking. You can use turkey kielbasa if you want a lighter version, but traditional kielbasa usually gives the richest taste.
Cream cheese, sour cream, and canned soup all work together to create that creamy casserole-style texture. Cheddar adds extra melt and flavor, while broth helps loosen the sauce enough for everything to cook together smoothly in the crock pot.
How to Make
1. Prepare the slow cooker
Lightly grease the crock pot with cooking spray or a little butter.
This helps prevent sticking and makes cleanup easier later.
2. Layer the pierogies and kielbasa
Add half of the frozen pierogies to the bottom of the crock pot. Scatter over some of the sliced kielbasa and chopped onion.
Repeat with the remaining pierogies, kielbasa, and onion so everything is layered evenly.
3. Make the creamy sauce
In a bowl, stir together the cream of mushroom soup or cream of chicken soup, sour cream, chicken broth, garlic powder, onion powder, salt, and black pepper.
Mix until mostly smooth. It does not need to be completely perfect because it will melt together as it cooks.
4. Add the cream cheese and butter
Scatter the cubed cream cheese over the layered pierogies and kielbasa, then add the butter in small pieces over the top.
These ingredients melt into the casserole and help make it especially rich and creamy.
5. Pour on the sauce
Pour the sauce mixture evenly over everything in the crock pot.
Try to spread it around so the pierogies get coated as evenly as possible.
6. Add the cheese
Sprinkle in about half of the shredded cheddar cheese.
The rest can go on later for a more melted cheesy finish.
7. Slow cook
Cover and cook on low for 4 to 5 hours or on high for 2 to 3 hours.
The pierogies should be tender, the kielbasa heated through, and the sauce creamy and well blended.
8. Stir gently
About halfway through cooking, if possible, give the casserole a gentle stir.
This helps distribute the melting cream cheese and makes the sauce smoother throughout.
9. Add the rest of the cheese
During the last 20 to 30 minutes of cooking, sprinkle the remaining cheddar cheese over the top.
Cover again and let it melt into the casserole.
10. Finish and serve
Once hot and creamy, serve the casserole warm. Top with green onions, parsley, bacon, or a little paprika if desired.
Tips for Best Results
Use frozen pierogies straight from the freezer. There is no need to thaw them first, and they usually hold their shape better that way during slow cooking.
Slice the kielbasa into even rounds so it heats consistently and mixes more evenly throughout the casserole.
Do not skip the broth. Even though this is a creamy dish, a little extra liquid helps everything cook together more smoothly and keeps the casserole from becoming too thick too early.
If you want the sauce extra smooth, stir once or twice during cooking if your schedule allows. This helps the cream cheese melt more evenly into the sauce.
Add the last layer of cheddar near the end instead of all at once. That gives the top a better melty finish and keeps the cheese from disappearing too much into the casserole.
Taste before serving. Depending on your soup, cheese, and kielbasa, you may or may not need extra salt.
Variations / Substitutions
This Crock Pot Pierogi Casserole with Kielbasa is easy to change based on what you have.
- Use turkey kielbasa instead of regular kielbasa
- Swap cheddar for Monterey Jack or Colby Jack
- Use cream of chicken instead of cream of mushroom
- Add sautéed mushrooms for extra flavor
- Stir in frozen peas near the end
- Add crumbled bacon for even more savory flavor
- Use smoked sausage if you do not have kielbasa

What to Serve With It
This casserole is rich and hearty, so lighter sides work especially well.
- Green salad
- Steamed green beans
- Roasted broccoli
- Cucumber salad
- Dinner rolls
- Roasted carrots
- Sauerkraut
- Simple coleslaw
A crisp salad or green vegetable helps balance the creamy texture of the casserole nicely.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days
- Freezer: Freeze for up to 2 months
- Reheating: Warm in the microwave or oven until heated through
- Best tip: Add a small splash of broth or milk before reheating if the sauce has thickened too much
Leftovers usually taste even better the next day once all the flavors settle together.
Common Mistakes to Avoid
One common mistake is not using enough liquid. The casserole should be creamy, not dry, so the broth helps more than it may seem at first.
Another is overcooking on high for too long. The pierogies can become too soft if left much longer than needed.
Adding all the cheese at the beginning can also make the dish feel heavier and less cheesy on top. Saving some for the end gives a better finish.
Finally, avoid stirring too aggressively. Pierogies are soft and can break apart if mixed roughly.
