When you crave a filling meal but can't be bothered with lots of fuss, this slow-cooked pierogi mashup with kielbasa is a real life-saver. Creamy pierogi and smoky sausage come together with hardly any effort in your crockpot. Anytime I make this, even a regular night at home suddenly feels cozy and special, especially when it’s cold outside and everyone’s hungry for something warm.
I tossed this together on a chilly day, just because friends randomly dropped by. They’re still asking me to whip it up again.
Tasty Ingredients
- Chopped chives: slice these fresh—they add a splash of green and bright flavor right before serving
- Salt and pepper: season to your liking but always have a taste of the sauce first
- Butter: for a rich sauce that pulls everything together—real butter works best
- Shredded cheddar cheese: adds a melty blanket on top—try extra sharp for a bolder punch
- Condensed cream of mushroom soup: this brings all the flavors together—stick with the brand you know
- Onion: diced up for sweetness and extra flavor—use fresh for max taste
- Sour cream: goes in for a tangy kick and creamy feel—full fat is the way to go
- Kielbasa: smoky sausage with snap—grab one from the deli if you can for the best flavor
- Frozen pierogi: these are the main stars—look for potato and cheese filling for the classic vibe
Easy Steps to Follow
- Finishing Touch:
- Once cheese is bubbling and melted, dish into bowls. Chop and sprinkle chives over the top for that fresh kick.
- Cheddar Blanket:
- About half an hour before it's done, throw shredded cheese on top, close the lid, and let it get gooey.
- Let It Go Low and Slow:
- Put the lid on and let the crockpot do its thing for four or five hours on low. Check after four by poking the pierogi with a fork. Don’t stir while it cooks.
- Do Layers Again:
- Stack the rest of the pierogi, then the rest of the kielbasa and onion, and pour on what’s left of the sauce. Smooth it all out so it cooks nice and even.
- Sauce Mix:
- In a bowl, blend soup, sour cream, and melted butter until it's super smooth. This is your creamy magic sauce.
- Add the Savory Goodies:
- Toss half your kielbasa slices and onions across the pierogi. You want every bite to be balanced with sausage and onion bits.
- Pierogi Foundation:
- Plop half your frozen pierogi down in a layer at the bottom. They give your casserole some serious backbone.
- Get the Slow Cooker Ready:
- Spritz the crockpot inside, making sure sides and bottom are coated so nothing sticks later.
- Sauce Up the Layers:
- Spoon on half the creamy sauce mix over your pierogi, sausage, and onion. Spread it around as much as you can so it all stays tender while cooking.

Cheesy bits on top never last long at my house. My kids race to grab the best scoop, and I can't lie—I sneak in some extra cheese for them when nobody’s looking.
How to Store Leftovers
Pop leftover casserole in the fridge for up to three days. Use containers that seal tight. When you reheat it in the oven or microwave, add a splash of milk or another dollop of sour cream to keep it creamy and smooth.
Swap Things Up
Try swapping kielbasa for other smoked sausages like turkey or andouille for a lighter or spicier twist. No cheddar? Monterey Jack or Swiss work great too. Greek yogurt steps in for sour cream if that’s what you’ve got at home.
Ways to Serve
This meal is super filling solo, but I like it with a crisp salad or some roasted veggies. I also stick some extra sour cream and a bottle of hot sauce on the table so everyone can pile on what they like.

Backstory
Pierogi and kielbasa are big-time comfort food in Eastern Europe, especially in Polish and Ukrainian homes. This dish is my shortcut take, inspired by the handmade pierogi dinners I remember from my old neighbors’ kitchens.
Frequently Asked Questions
- → Can I swap frozen pierogi with fresh ones?
For sure! Fresh pierogi work great. Just check them a bit sooner since they get tender quicker.
- → Are leftovers good the next day?
Oh yeah. Pop any extras in a sealed container and keep them in the fridge up to three days. Warm gently so they don’t dry out.
- → What's a good kielbasa substitute?
You can try using smoked sausage, bratwurst, or some cooked bacon instead. Season to taste since flavors can differ.
- → How do I go meat-free for this meal?
Just leave out the kielbasa and switch the soup to veggie broth. Toss in extra veggies like peppers or mushrooms for more flavor.
- → How do I stop pierogi from clumping together?
Layer stuff with the sauce and toppings. That way, pierogi stay apart and come out moist each time.
- → Can I prep this ahead of time?
Yup! You can put everything into your slow cooker insert, snap on a lid, and keep it in the fridge overnight. Just start cooking the next day.
