Ingredients You’ll Need
This recipe keeps things straightforward with simple ingredients that come together into something far more than the sum of their parts. Each component plays an essential role, delivering flavor, creaminess, and that unforgettable texture that makes Crockpot Pierogi Casserole with Kielbasa such a crowd-pleaser.
- Frozen potato and cheese pierogies: These bring a pillowy, carb-laden base filled with cheesy, potato goodness. Use your favorite flavor, or get adventurous!
- Smoked kielbasa: Sliced into rounds, this adds a savory, smoky depth and a hearty, meaty bite to every forkful.
- Shredded cheddar cheese: Sprinkled on top for melty, gooey richness and a beautiful golden finish.
- Cream cheese: Cubed and softened, it melts seamlessly into the sauce, making everything luxuriously creamy.
- Sour cream: Adds tang and balances the richness of the dish.
- Chicken broth: Keeps the sauce just the right level of saucy and flavorful, helping everything meld together.
- Onion: Sautéed until sweet and tender, it gives a mellow backbone to your casserole.
- Garlic: Just enough to add savory character without overpowering the other ingredients.
- Black pepper: Brings a gentle hint of warmth to round out the flavors.
- Paprika: Adds color and a subtle smokiness that pairs perfectly with kielbasa.
- Butter: Helps the onions sauté beautifully and infuses the base with richness.
How to Make Crockpot Pierogi Casserole with Kielbasa
Step 1: Sauté the Aromatics
Start by melting the butter in a skillet over medium heat. Add the diced onion and sauté until it’s soft and starting to turn a light golden color, which should take around five minutes. Stir in the minced garlic and let it cook for just about a minute, until fragrant. This step builds a deeply flavorful foundation for the dish and ensures that every bite is packed with sweet, savory undertones.
Step 2: Whip Up the Creamy Sauce
In a large mixing bowl, combine the softened cream cheese, sour cream, chicken broth, black pepper, and paprika. Stir everything until the sauce is mostly smooth (it’s fine if some lumps of cream cheese remain—they’ll melt in the slow cooker). This creamy mixture is the secret to turning ordinary pierogies and kielbasa into an irresistible casserole.
Step 3: Layer the Crockpot Pierogi Casserole with Kielbasa
Now comes the fun part! In a greased crockpot, layer half of the frozen pierogies evenly across the bottom. Top this with half of the sliced kielbasa, then spread on half of the sautéed onion and garlic mixture, and finish with half of the cream cheese sauce. Repeat the entire process with the remaining ingredients to create beautiful, flavor-packed layers.
Step 4: Cook Until Bubbly and Delicious
Cover your crockpot and cook on low for 4 to 5 hours or on high for 2 to 2.5 hours. This hands-off method means all the flavors meld together perfectly, while the pierogies turn blissfully tender and the kielbasa soaks up all the creamy goodness.
Step 5: Add the Cheesy Finale
For the most mouthwatering finish, sprinkle the shredded cheddar cheese over the top of the casserole during the last 15 minutes of cooking. Cover the crockpot again to let the cheese melt into a bubbly, golden layer. Serve the Crockpot Pierogi Casserole with Kielbasa warm, and get ready for a wave of compliments at the table.
How to Serve Crockpot Pierogi Casserole with Kielbasa

Garnishes
To highlight the creamy, savory elements, sprinkle fresh chopped green onions or parsley just before serving. A dash of extra black pepper or a pinch of smoked paprika adds a lovely finishing touch. If you love a little zing, a dollop of extra sour cream on top takes this Crockpot Pierogi Casserole with Kielbasa straight to comfort-food heaven.
Side Dishes
This hearty main dish is perfect with lighter sides. Pair it with a simply dressed green salad, steamed green beans, or buttery peas to balance out the richness. A loaf of warm, crusty bread or a side of pickled beets is also a lovely nod to Eastern European tradition.
Creative Ways to Present
You can serve the Crockpot Pierogi Casserole with Kielbasa right from the slow cooker for a rustic, family-style meal, or portion it into mini cast iron skillets or ramekins for an extra-cute presentation at parties. For a potluck or buffet, scoop it into a large casserole dish and set out a toppings bar with fresh herbs, extra cheese, and crispy fried onions.
Make Ahead and Storage
Storing Leftovers
Any leftovers of this casserole are a true treat for future you! Let the dish cool completely, then store in an airtight container in the refrigerator for up to four days. The flavors actually deepen as it sits, making it even more irresistible the next day.
Freezing
If you’d like to freeze your Crockpot Pierogi Casserole with Kielbasa, portion it into individual servings or store the entire batch in a freezer-safe container. It will keep well for up to two months. For best results, thaw in the refrigerator overnight before reheating.
Reheating
To bring leftovers back to their full, creamy glory, reheat in the microwave in 1-2 minute bursts, covered, until piping hot. You can also gently warm the casserole in an oven-safe dish at 350°F (about 20-25 minutes, covered) or in the slow cooker on the “warm” setting for an easy hands-off option.
FAQs
Can I use fresh pierogies instead of frozen?
Absolutely! If you have access to fresh pierogies, just reduce the slow cooker cooking time by about an hour, since they tend to cook a bit faster than frozen.
Is it necessary to brown the kielbasa first?
While you can add the kielbasa straight to the crockpot, browning it in a skillet beforehand gives extra flavor and a nice crisp texture. It’s a simple extra step that can make a big difference if you have the time!
Can I add vegetables to the Crockpot Pierogi Casserole with Kielbasa?
Of course! Mushrooms, bell peppers, or even a handful of spinach would work nicely. Just be sure to sauté heartier vegetables first so they’re tender by serving time.
What’s the best way to make this casserole ahead for a party?
Prepare and layer all the ingredients in the crockpot insert the night before, then cover and refrigerate. The next day, just place the insert in the base and start the cooking process as directed—a total lifesaver for busy hosts!
Can I use low-fat or dairy-free swaps in this recipe?
You can! Low-fat sour cream and light cream cheese will lighten things up, but the texture will be less rich. For dairy-free, reach for your favorite plant-based sour cream, cream cheese, and cheddar alternatives—just note that flavor and meltiness may vary slightly.
Final Thoughts
If you’re longing for some classic comfort that practically cooks itself, I hope you’ll give Crockpot Pierogi Casserole with Kielbasa a spot in your weekly rotation. The creamy, cheesy goodness and smoky kielbasa make each plate a celebration—perfect for feeding a crowd, sharing with loved ones, or stashing in your freezer for an easy weeknight win.
