How to Make Crockpot Pierogi Casserole with Kielbasa
Step 1: Prepare the Kielbasa
Slice the kielbasa into bite-sized rounds.
You can add it directly to the slow cooker, but browning the sausage first gives the casserole even more flavor.
To brown it, heat a skillet over medium-high heat and cook the kielbasa for several minutes until lightly golden around the edges.
Step 2: Prepare the Crockpot
Lightly grease the inside of your slow cooker with butter or cooking spray.
This helps prevent the cheese and pierogies from sticking around the edges.
Step 3: Add the Pierogies
Place the frozen pierogies into the crockpot.
There’s generally no need to thaw them first.
Potato and cheddar pierogies are especially delicious, but other savory varieties can work too.
Step 4: Add the Kielbasa
Scatter the sliced kielbasa over the pierogies.
Try to distribute the sausage throughout the slow cooker so every serving gets plenty of smoky kielbasa.
Step 5: Add the Seasonings
Sprinkle garlic powder, onion powder, paprika, and black pepper over the pierogies and sausage.
Kielbasa and cheese can already contain plenty of salt, so taste the finished casserole before adding additional salt.
Step 6: Add Chicken Broth
Pour chicken broth around the pierogies.
The broth provides moisture while everything cooks and helps create the base for the creamy sauce.
You don’t need to completely cover the pierogies.
Step 7: Add Cream Cheese
Cut softened cream cheese into cubes.
Scatter the cubes throughout the slow cooker.
As the casserole cooks, the cream cheese will soften and combine with the broth to create a rich, creamy sauce.
Step 8: Add Cheddar
Sprinkle shredded cheddar cheese over the mixture.
Save a little cheese for the final topping if you want an extra-cheesy finish.
Freshly shredded cheddar generally melts more smoothly than pre-shredded cheese.
Step 9: Slow Cook
Cover the crockpot.
Cook on LOW for approximately 3–4 hours or until the pierogies are tender and heated through.
Slow cooker temperatures vary, so begin checking earlier if your crockpot runs hot.
Avoid cooking the pierogies much longer than necessary because they can become overly soft.
Step 10: Stir the Sauce
Once the cream cheese is soft, gently stir the casserole.
Be careful because cooked pierogies can break apart if stirred too aggressively.
The cream cheese, cheddar, and broth should combine into a rich sauce surrounding the pierogies and sausage.
Step 11: Adjust the Consistency
If the sauce looks too thick, stir in a small splash of chicken broth or milk.
If you want it richer, add a little sour cream or extra cream cheese.
The finished casserole should be creamy without becoming soupy.
Step 12: Add Extra Cheddar
Sprinkle the reserved cheddar over the top.
Cover for another 5–10 minutes, or until the cheese has melted.
This creates an extra-cheesy top layer.
Step 13: Garnish
Finish with sliced green onions, fresh parsley, or chopped chives.
You can also add crispy bacon pieces for a loaded pierogi casserole.
Step 14: Serve Warm
Scoop the pierogies, kielbasa, and creamy cheese sauce into bowls or onto plates.
Serve immediately while everything is warm and cheesy.

Frequently Asked Questions
Do I need to thaw frozen pierogies?
Usually, no.
Frozen pierogies can be added directly to the crockpot. Just make sure they’re heated completely through before serving.
What kind of pierogies work best?
Potato and cheddar pierogies are an excellent choice because their filling complements the kielbasa and creamy cheese sauce.
Onion, potato, or other savory cheese varieties can also work.
Do I have to brown the kielbasa first?
No.
Most packaged kielbasa is already fully cooked and can be sliced and added directly to the crockpot. Check the package to confirm.
However, quickly browning the slices gives them caramelized edges and deeper flavor.
Can I add onions?
Absolutely.
Sautéed or caramelized onions are especially good with pierogies and kielbasa.
Can I add bacon?
Yes!
Cook the bacon until crispy and sprinkle it over the casserole before serving.
Can I use another sausage?
Yes.
Smoked sausage is the easiest substitute.
You could also use another fully cooked sausage that complements the creamy cheese sauce.
Can I add sour cream?
Definitely.
Stir sour cream into the casserole near the end for extra tanginess and classic pierogi flavor.
Can I make it spicy?
Yes.
Use spicy kielbasa, Pepper Jack cheese, red pepper flakes, or a little hot sauce.
Why are my pierogies falling apart?
They were probably cooked too long or stirred too aggressively.
Once the pierogies become tender, stir the casserole gently and avoid unnecessary additional cooking.
Can I double the recipe?
Yes, provided your slow cooker is large enough.
Avoid packing it completely full because the ingredients need enough space to heat evenly.

Why This Recipe Works
Pierogies already contain the perfect comfort-food combination of tender dough, potatoes, and cheese. Pairing them with smoky kielbasa transforms them into a hearty main dish.

The smoky sausage balances the creamy potatoes and cheese, while garlic, onion, and paprika add savory flavor throughout the casserole.
The result is a creamy, cheesy, smoky slow cooker dinner with tender pierogies and plenty of kielbasa in every serving.
This Crockpot Pierogi Casserole with Kielbasa is easy, hearty, cheesy, and perfect for busy weeknights, potlucks, game day, or cozy fall and winter dinners.
