Step-by-Step Instructions
Step 1: Prepare the Ingredients
Slice the kielbasa into bite-sized rounds.
Chop the onion.
Cube the cream cheese to help it melt evenly.
There’s no need to thaw the pierogies—they can go straight into the crockpot frozen.
Step 2: Layer the Slow Cooker
Lightly grease your crockpot insert.
Start layering:
Half of the frozen pierogies
Half of the sliced kielbasa
Half of the chopped onion
Sprinkle with cheddar cheese
Repeat the layers with the remaining ingredients.
Step 3: Add the Creamy Sauce
In a bowl, whisk together:
Chicken broth
Heavy cream
Garlic powder
Black pepper
Pour the mixture evenly over the layered ingredients.
Scatter the cubed cream cheese over the top.
Step 4: Slow Cook to Perfection
Cover and cook:
Low: 4–5 hours
High: 2–3 hours
About 30 minutes before serving, gently stir to help the cream cheese fully incorporate into the sauce.
The casserole is ready when the pierogies are tender and everything is coated in a thick, creamy sauce.
Finishing Touches
Sprinkle with fresh parsley for brightness.
Add a little extra shredded cheese on top and let it melt for a richer finish.
Serve warm with:
A crisp green salad
Steamed green beans
Or crusty bread to soak up the sauce
Tips for the Best Results
Use full-fat cream cheese for the creamiest texture.
Avoid over-stirring early in the cooking process to prevent pierogies from breaking.
For extra depth, brown the kielbasa in a skillet before adding it to the crockpot.
If the sauce seems thin, remove the lid for the final 20 minutes to thicken.
Make It Your Own
This recipe is incredibly adaptable. Try:
Adding crispy bacon bits
Swapping cheddar for smoked gouda
Stirring in a spoonful of Dijon mustard for tang
Mixing in sauerkraut for a traditional Polish-inspired twist
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days.
To reheat:
Microwave individual portions
Or warm gently on the stovetop with a splash of milk to loosen the sauce
It also freezes well, though the sauce may thicken slightly upon reheating.
