Save to Pinterest My sister brought this to a potluck once, and I watched the entire dish vanish in under twenty minutes. People kept circling back with empty plates, asking what was in it. When she told me it was just pierogis and kielbasa tossed in a crockpot, I didn't believe her. The next week, I made it myself on a rainy Tuesday, and by dinner time, my kitchen smelled like a Polish grandmother had moved in.
I started making this on Sundays when my kids had soccer practice and I had zero energy left for elaborate dinners. I'd toss it all in the crockpot before we left, and by the time we got home, the house smelled so good the neighbors texted asking what I was cooking. It became our unofficial team dinner tradition. Now, even my pickiest eater asks for it by name.
Ingredients
- Frozen potato and cheese pierogi: These little dumplings are the heart of the dish, buy the good ones from the freezer aisle and don't bother thawing them first.
- Kielbasa sausage: Look for a quality smoked variety, the smoky flavor seeps into everything and makes the whole casserole taste like it's been slow roasted over a campfire.
- Condensed cream of mushroom soup: This acts as the creamy base that binds everything together, you can use cream of chicken if that's what you have on hand.
- Sour cream: It adds a tangy richness that cuts through the heaviness and keeps each bite interesting.
- Shredded cheddar cheese: Go for sharp cheddar if you want a bolder flavor, it melts into gooey pockets throughout the casserole.
- Yellow onion: Slice it thin so it softens completely and sweetens as it cooks, adding a subtle depth you'll notice but can't quite name.
- Garlic powder, black pepper, smoked paprika: These seasonings are quiet heroes, the paprika especially adds a whisper of smokiness that makes people ask for your secret.
- Fresh chives or parsley: A handful of green at the end makes it look like you tried, even though you didn't.
Instructions
- Prep the crockpot:
- Lightly grease the insert with butter or cooking spray so nothing sticks to the bottom later. This step takes ten seconds and saves you from scrubbing later.
- Layer the first round:
- Spread half the frozen pierogi evenly across the bottom, then scatter half the kielbasa slices and onions on top. Don't overthink the arrangement, it all gets mixed up as it cooks anyway.
- Make the creamy sauce:
- Whisk together the soup, sour cream, garlic powder, black pepper, and paprika in a bowl until smooth. It should look like a thick, pale gravy.
- Build the layers:
- Spoon half the sauce over the first layer, spreading it gently, then sprinkle half the cheddar on top. Repeat the whole process with the remaining pierogi, kielbasa, onions, sauce, and cheese.
- Slow cook to perfection:
- Cover the crockpot and set it to low for four hours. When it's done, the pierogi will be tender, the cheese melted and bubbly, and everything will smell like comfort itself.
- Garnish and serve:
- Sprinkle chopped chives or parsley over the top if you want it to look fancy. Scoop generous portions into bowls and watch people go quiet while they eat.
Save to Pinterest The first time I served this to my in laws, my mother in law got quiet halfway through her second helping. I thought I'd done something wrong until she looked up and said it reminded her of her childhood in Pennsylvania. She told me stories about her grandmother's kitchen while we finished the rest of the casserole together. I've made it for her at least a dozen times since, and every time, she smiles before she even takes a bite.
How to Store and Reheat
Leftovers keep in an airtight container in the fridge for up to four days, and honestly, they taste even better the next day when the flavors have melded together. Reheat individual portions in the microwave for about two minutes, stirring halfway through, or warm the whole batch in a covered dish in a 350 degree oven for twenty minutes. If it seems dry, stir in a spoonful of sour cream or a splash of milk before reheating.
Easy Swaps and Variations
I've made this with turkey kielbasa when I wanted something lighter, and it still turned out great, just a little less smoky. You can also try different pierogi flavors like sauerkraut and mushroom or even sweet potato if you're feeling adventurous. One time I stirred in a bag of fresh spinach during the last thirty minutes of cooking, and it added a nice pop of color without changing the flavor much.
What to Serve Alongside
This casserole is rich and hearty, so I usually serve it with something crisp and bright to balance it out. A simple green salad with a tangy vinaigrette works perfectly, or steamed broccoli tossed with a little lemon juice and salt. If you want to go full comfort mode, serve it with buttered rye bread for dipping into the creamy sauce.
- Crisp green salad with vinaigrette
- Steamed broccoli with lemon
- Buttered rye or sourdough bread

Recipe FAQs
- → Can I use fresh pierogi instead of frozen?
Yes, fresh pierogi work wonderfully. Reduce cooking time to 3 hours on low and check for tenderness, as fresh pierogi cook faster than frozen.
- → What can I substitute for kielbasa?
Turkey sausage, smoked chicken sausage, or andouille work well. For a vegetarian version, try smoked tempeh or skip the meat entirely and add extra vegetables like mushrooms and bell peppers.
- → Can I make this ahead of time?
Absolutely. Assemble all layers in your crockpot insert the night before, cover, and refrigerate. In the morning, place the insert in the base and cook as directed, adding 30 minutes to account for the cold start.
- → How do I prevent the casserole from drying out?
Keep the lid on throughout cooking to trap moisture. If you notice it's getting dry near the end, add a splash of chicken broth or milk and stir gently.
- → What sides pair well with this casserole?
A crisp green salad, steamed broccoli, roasted Brussels sprouts, or sautéed green beans balance the richness beautifully. Crusty bread is also excellent for soaking up the creamy sauce.
- → Can I freeze leftovers?
Yes, portion cooled leftovers into airtight containers and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat in the oven at 350°F until warmed through.
