Save I discovered this pierogi casserole recipe during a particularly harsh winter when comfort food became our family's salvation. The aroma of sautéed kielbasa and onions wafting through my kitchen instantly transformed our mood from winter blues to cozy contentment. My grandmother, with her Polish heritage, would have been proud of this shortcut version that still captures those essential old-world flavors. What began as a hurried weeknight experiment has become one of our most requested family meals.
Last autumn, I brought this casserole to our neighborhood block party, unsure how it would be received alongside the usual potluck fare. I watched nervously as people took their first bites, then smiled as they returned for seconds and thirds. An elderly gentleman approached me later, eyes bright with emotion, saying it reminded him of meals his mother made when he was a boy in Pittsburgh. That connection across generations made this simple slow cooker dish feel truly special.
Ingredients
- Frozen potato and cheese pierogi: The star of this dish, these plump little dumplings become wonderfully tender in the slow cooker while absorbing all the surrounding flavors.
- Kielbasa: I prefer the traditional smoked Polish variety for its robust flavor, but I've learned that turkey kielbasa works beautifully for a lighter option.
- Yellow onion: Thinly slicing helps it almost melt into the sauce, providing a sweet background note that balances the richness.
- Cheddar cheese: A sharp variety adds the most flavor, though a mild one works if you're feeding picky eaters or children.
- Cream of mushroom soup: This convenient shortcut creates a silky sauce base without hours of preparation.
- Sour cream: The tangy richness cuts through the heaviness and adds incredible creaminess.
Instructions
- Prep your slow cooker:
- A light coating of cooking spray prevents sticking and makes cleanup so much easier. This five-second step saves so much scrubbing later.
- Create your first layer:
- Arrange half the frozen pierogi in a single layer at the bottom of your slow cooker. No need to thaw them first, they'll cook perfectly from frozen.
- Add the meaty goodness:
- Distribute half the kielbasa slices and onions evenly over the pierogi. The way the kielbasa releases its smoky flavor throughout the dish is absolutely magical.
- Bring on the cheese:
- Sprinkle that first cup of shredded cheddar generously, making sure to reach the edges. This middle layer of cheese becomes wonderfully gooey and stretchy.
- Repeat your layers:
- Add the remaining pierogi, kielbasa, onions, and another cup of cheese just like before. These distinct layers create pockets of flavor throughout the casserole.
- Create your creamy sauce:
- Whisk the soup, sour cream, milk, garlic powder, and black pepper until smooth. The sauce should be pourable but still thick enough to coat the back of a spoon.
- Pour and cover:
- Drizzle the sauce evenly over everything, allowing it to seep between the layers. Cover with the lid to trap all that wonderful steam and flavor.
- Let it work its magic:
- Cook on LOW for 4 hours until everything is hot, bubbly, and the pierogi are tender. Your kitchen will smell absolutely incredible during the last hour.
- Add the finishing touch:
- A sprinkle of fresh herbs adds color and a bright flavor contrast to the rich casserole. Chives are my personal favorite for their mild oniony bite.
Save My teenage son, who typically avoids anything resembling a casserole, became an instant convert to this dish on a night when basketball practice ran late and homework loomed. He wolfed down two servings while working through algebra problems, then looked up with such genuine appreciation that I felt like I'd won some secret parenting award. Now he requests it before big exams or games, believing it brings him luck, and I'm happy to maintain the tradition.
Make-Ahead Tips
I've learned through several rushed mornings that you can assemble this casserole the night before, refrigerate the crock insert, and simply place it in the slow cooker base before leaving for work. The chilled ingredients may need an extra 30 minutes of cooking time, but the convenience is worth it. This advance preparation also allows the flavors to begin melding overnight, resulting in an even more cohesive dish.
Serving Suggestions
The richness of this casserole practically begs for something crisp and fresh alongside it. A simple salad with a vinaigrette dressing provides the perfect counterpoint to the creamy, carb-heavy main dish. On particularly indulgent evenings, I've been known to serve buttered rye bread on the side for sopping up the incredible sauce, though I try not to make this a regular habit for the sake of our waistlines.
Variations to Try
This recipe welcomes personalization based on what you have on hand or your family's preferences. I once made an impromptu version with cream of chicken soup when I discovered my pantry lacked mushroom, and several family members actually preferred that lighter flavor profile. Different pierogi flavors work beautifully too, with sauerkraut or potato-onion varieties creating subtle but delicious variations.
- For a spicier version, add a teaspoon of smoked paprika to the sauce and use pepper jack instead of cheddar cheese.
- Vegetarians can skip the kielbasa and add 2 cups of sautéed mushrooms and bell peppers instead.
- For extra indulgence on special occasions, stir in ¼ cup of cream cheese to the sauce mixture before pouring over the layers.
Save This crockpot pierogi casserole has become more than just dinner in our house, it's a reminder that comfort food brings people together. Whether you're feeding a hungry family or looking for a dish to share at your next gathering, these humble ingredients combine to create something truly special.
Questions & Answers

Yes, fresh pierogi work well in this dish. Reduce cooking time to 3-3.5 hours on low since fresh dumplings cook faster than frozen ones. Check for tenderness after 3 hours to prevent overcooking.
- → What other meats can I substitute for kielbasa?
You can use smoked sausage, Polish sausage, bratwurst, or even diced ham. Turkey kielbasa makes a lighter version, while andouille adds a spicy kick. For a different flavor profile, try bacon or pancetta.
- → Can I make this casserole in the oven instead?
Absolutely. Assemble everything in a 9x13 baking dish, cover with foil, and bake at 350°F for 45 minutes. Uncover and bake an additional 15 minutes until bubbly and golden on top.
- → How do I store and reheat leftovers?
Store in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes, or reheat the entire casserole in a 350°F oven covered with foil for about 20 minutes until hot.
- → Can I make this ahead of time?

A crisp green salad with vinaigrette cuts through the richness. Steamed broccoli, green beans, or roasted Brussels sprouts also complement the creamy, cheesy elements. Pickled vegetables provide a nice acidic contrast.
