This crockpot pierogi casserole transforms humble ingredients into a soul-warming meal that reminds me of my grandmother's kitchen. The combination of tender pierogies and savory kielbasa creates a one-pot wonder that practically cooks itself while filling your home with irresistible aromas.
I discovered this recipe during a particularly cold winter when I needed something hearty that could cook while I was shoveling snow. It has since become our family's go-to meal whenever we have guests—everyone always asks for the recipe!
Ingredients
- Frozen pierogies: Bring the perfect pillowy texture without any work
- Kielbasa: Adds smoky richness that permeates the entire dish
- Diced onion and garlic: Create an aromatic foundation
- Sour cream: Lends tanginess and creaminess to balance the richness
- Cream of mushroom soup: Provides depth without fussy sauce-making
- Vegetable broth: Helps create the perfect consistency
- Shredded cheddar cheese: Forms an irresistible melty top layer
- Onion powder and garlic powder: Intensify the savory elements
- Paprika: Adds subtle warmth and beautiful color
- Fresh parsley: Brightens the finished dish with color and freshness
Step-by-Step Instructions
- Prepare the Slow Cooker:
- Properly greasing your crockpot prevents sticking and makes cleanup infinitely easier. I use a light coating of olive oil spray, making sure to cover the sides as well as the bottom. This simple step saves tremendous frustration later when it's time to serve and clean up.
- Create the Foundation Layer:
- Arrange half the frozen pierogies in a single layer at the bottom of your prepared crockpot. No need to thaw them first. Place them potato side down for the best texture. Follow with half the kielbasa slices, distributing them evenly. The kielbasa will release flavorful oils as it cooks, infusing the pierogies below.
- Build the Flavor Base:
- Scatter half the diced onion and minced garlic over your first layer. Season this layer thoroughly with half the onion powder, garlic powder, paprika, salt, and pepper. These seasonings will penetrate the pierogies as they cook, ensuring they are flavorful throughout rather than just on the surface.
- Prepare the Creamy Mixture:
- In a large bowl, whisk together the sour cream, cream of mushroom soup, and vegetable broth until completely smooth. This mixture should have a pourable consistency but still be thick enough to coat the back of a spoon. Pour half of this velvety sauce over your first layer, allowing it to seep between the pierogies and kielbasa.
- Complete the Layering:
- Repeat the entire process with your remaining ingredients. The second layer should mirror the first exactly. This layering technique ensures that every serving has the perfect balance of pierogies, kielbasa, and creamy sauce in each bite.
- The Long, Slow Cook:
- Cover your crockpot and set it to low for 4 to 6 hours. The slow cooking process allows the flavors to meld beautifully while keeping the pierogies tender rather than mushy. Your house will smell amazing as this cooks!
- The Finishing Touch:
- About 15 minutes before serving, sprinkle the shredded cheddar cheese over the top and replace the lid. The residual heat will melt the cheese perfectly without overcooking it. This creates a beautiful golden cheese pull when serving.
- Serve with Care:
- Gently stir the casserole just enough to distribute the sauce evenly without breaking up the pierogies. Garnish with fresh parsley for a pop of color and fresh flavor contrast. Serve in wide, shallow bowls to showcase all the components.

My favorite part of this recipe is how the kielbasa infuses everything with its distinctive flavor. My Polish grandfather used to make homemade kielbasa, and this dish always brings back memories of summer visits to his smoky backyard where lengths of sausage hung drying. While store-bought kielbasa works perfectly here, if you have access to a good Polish deli, their authentic kielbasa will elevate this dish even further.
Make-Ahead Options
This casserole is perfect for busy households. You can assemble everything up to 24 hours before cooking, keeping it refrigerated until you're ready to start the slow cooker. Just add about 30 minutes to the cooking time if starting from cold. The finished casserole also freezes beautifully in individual portions. Simply thaw overnight in the refrigerator and microwave until heated through for quick weeknight dinners when time is tight.
Smart Substitutions
While potato and cheddar pierogies are traditional in this recipe, feel free to experiment with other varieties. Sauerkraut pierogies add a tangy twist that complements the kielbasa beautifully. For a lighter version, turkey kielbasa works wonderfully, reducing the fat content without sacrificing flavor. Lactose-intolerant guests can still enjoy this dish by substituting dairy-free sour cream and a good melting non-dairy cheese. The cream of mushroom soup can be swapped for cream of chicken or even a homemade white sauce if you prefer to avoid canned ingredients.
Serving Suggestions
This hearty casserole pairs wonderfully with crisp side dishes that offer textural contrast. A simple green salad dressed with vinaigrette cuts through the richness perfectly. For authentic Polish flair, serve with braised red cabbage or quick-pickled cucumber salad. Crusty rye bread on the side provides the perfect vehicle for sopping up every last bit of the creamy sauce. For a festive touch during holiday gatherings, serve with a dollop of applesauce on the side, a traditional Polish accompaniment to savory dishes.

Frequently Asked Questions
- → Can I use homemade pierogies instead of frozen?
Yes, homemade pierogies work beautifully in this casserole. Since they're typically fresher and more delicate than frozen varieties, you may want to reduce the cooking time by 30-60 minutes to prevent them from becoming too soft.
- → What can I substitute for cream of mushroom soup?
Cream of chicken or cream of celery soup make excellent substitutions. For a homemade alternative, make a roux with 2 tablespoons each of butter and flour, then whisk in 1 cup of milk or broth and season with herbs until thickened.
- → Can this casserole be made ahead of time?
Yes! You can assemble all the ingredients in the crockpot insert the night before, refrigerate overnight, and start cooking the next day. Add about 30 minutes to the cooking time if starting from cold.
- → What sides pair well with this pierogi casserole?
A simple green salad, steamed vegetables like broccoli or green beans, or a tangy cucumber salad complement this rich casserole beautifully. Rye bread or a crusty baguette is perfect for soaking up the creamy sauce.
- → Can I freeze leftovers of this casserole?
Yes, this casserole freezes well for up to 3 months. Portion into airtight containers, cool completely before freezing, and thaw overnight in the refrigerator before reheating in the microwave or oven until hot throughout.
- → What type of kielbasa works best in this dish?
Traditional Polish smoked kielbasa provides the most authentic flavor, but any smoked sausage variety works well. Turkey or chicken kielbasa offers a lighter alternative, while chorizo or andouille can add a spicy twist to the dish.
