This stick-to-your-ribs kielbasa potato soup mixes smoky Polish sausage with soft potatoes in a thick, cheese-loaded broth that'll warm you right up. The mix of crunchy sausage pieces and soft potatoes gives you an awesome texture mix, while the garlicky, cheese-packed broth ties everything together beautifully. It's the type of soup that makes you want to grab a blanket and enjoy a big bowl by the fire.
I stumbled on this soup during a freezing cold winter when I was diving into old-school Polish dishes. The way the cheese stretches into long strands with every spoonful reminded me of the comfort meals my grandma would cook. It's now my favorite pick when the weather turns cold.
Key Ingredients
- Kielbasa: Go for top-notch smoked Polish sausage. That smokiness is what gives the soup its standout taste
- Potatoes: Firm varieties like Yukon Gold or Maris Piper won't fall apart while cooking, keeping your soup from turning mushy
- Fresh Garlic: Skip the jar stuff; only fresh cloves will give you that perfect flavor base
- Cheddar Cheese: Shred it yourself instead of buying pre-shredded bags for much better melting
- Aromatics (Onion, Carrot, Celery): This veggie trio builds an amazing flavor foundation for your broth
Step-By-Step Cooking Guide
- Get The Sausage Ready:
- Slice kielbasa into smaller chunks that fit nicely on your spoon
- Put a sturdy Dutch oven on medium heat
- Cook the sausage until the edges get nice and crispy, around 4-5 minutes
- Take it out with a slotted spoon, but keep all those tasty drippings in the pot
- Start The Flavor Base:
- Toss your chopped onion, carrot, and celery into those leftover sausage oils
- Cook them down until they're soft and the onions look see-through
- Mix in the fresh garlic and red pepper flakes if you want some heat
- Let everything get nice and fragrant, about a minute
- Put The Soup Together:
- Throw in the potato chunks and pour in chicken stock
- Let it come to a light boil, then turn down the heat
- Cover and let it simmer until you can easily poke the potatoes with a fork
- Slowly pour in warmed milk to keep it from separating
- Wrap It Up And Serve:
- Put the crispy kielbasa back in the pot
- Drop in cheese a little at a time, stirring until it's all melted
- Let it bubble until it's as thick as you like
- Sprinkle some fresh parsley on top before serving

When I first started cooking this soup, I figured out the hard way that the kielbasa quality really matters. The smoked kielbasa from my neighborhood Polish shop adds an amazing depth that turns this simple soup into something really special.
Getting That Perfect Thickness
Getting the right texture comes down to how you handle those potatoes. I've learned that cutting them into equal, small chunks means they'll cook evenly but still keep their shape. Sometimes I'll smoosh a few potato pieces against the pot to thicken the broth naturally without making it too heavy.
Prep Ahead And Storing
After making tons of batches, I've noticed this soup actually tastes even better the day after you make it, once all the flavors have had time to mix together. Keep it in a sealed container in your fridge for up to three days. When you warm it up, do it slowly over low heat, stirring now and then so the cheese doesn't separate.
What To Serve With It
This soup is filling enough to stand alone, but I love dunking some crusty rye bread into it for that authentic Polish feel. A basic green salad with a light dressing helps cut through the richness. For special dinners, I sometimes hollow out bread loaves to use as edible bowls.
Different Ways To Make It
I've played around with this recipe a lot over the years. Adding some sauerkraut brings a nice tangy twist that works really well. Sometimes I'll throw in handfuls of kale or spinach for more nutrients, or switch the cheddar for smoked gouda to bump up that smoky flavor even more.

After whipping up this soup more times than I can count, I can tell you it's way more than just food - it's like a hug in a bowl. Whether I'm having it on a cold night or taking it to a friend's place, this kielbasa potato soup always gets rave reviews. The way the smoky sausage flavor runs through the whole pot, how the cheese stretches when you lift your spoon, and those perfect potato bites make this soup a real cold-weather champion. It's become my go-to comfort food that works every single time.
