Ingredients For This Potato and Kielbasa Soup
- 1 tablespoon olive oil
- 300g (10.5 oz) kielbasa sausage, cut into bite-size pieces
- 1 medium onion, diced
- 1 medium carrot, diced
- 2 celery ribs, diced
- 4 garlic cloves, finely chopped
- ½ teaspoon red chili flakes (adjust to your spice preference)
- 750g (1½ lb) potatoes, peeled and cubed
- 1.25 liters (5 cups) chicken stock

- 100g (3.5 oz) cheddar cheese, grated

How To Make The Best Kielbasa Potato Soup
Preparing The Base
- Heat the olive oil in a large pot or Dutch oven over medium heat. Add the kielbasa pieces and cook for 4-5 minutes until they develop a slight crisp on the edges. Remove the sausage with a slotted spoon and set aside. (I love how the kielbasa leaves behind its flavorful oils - this is where the magic begins!)
- In the same pot with the leftover oils, add the diced onion, carrot, and celery. Cook for about 5 minutes until the vegetables soften.
- Add the chopped garlic and red chili flakes, stirring for another minute until fragrant. (Your kitchen will smell amazing at this point - I always take a moment to appreciate these aromas!)


Adding Potatoes And Building Flavor
- Add the cubed potatoes and chicken stock to the pot. Bring everything to a boil, then reduce to a simmer. Cover with a lid and let cook for 10-12 minutes, or until the potatoes are fork-tender. (Don't overcook the potatoes or they'll fall apart completely - unless that's what you're going for!)
- Take a ladle of the hot soup and mix it with the milk in a measuring cup or bowl. This tempers the milk so it doesn't curdle when added to the hot soup. Pour this mixture back into the pot.
- Return the crispy kielbasa pieces to the soup and stir everything together.


Creating The Creamy Finish
- Add the grated cheddar cheese and stir until it's completely melted into the soup. (This is what makes the soup so luxurious - don't skimp on the cheese!)
- Let the soup simmer for 2-3 more minutes until it thickens slightly, then stir in the chopped parsley.
- Season with salt and pepper to taste. Remember that the kielbasa and chicken stock already contain salt, so taste before adding more.
- Serve in bowls with extra grated cheese on top if desired. A side of crusty bread makes this the perfect meal!
Storage And Reheating Tips For Your Soup
This polish sausage potato soup keeps well in the fridge for up to 3 days in an airtight container. The flavors actually get better the next day, making it perfect for meal prep!
You can reheat it on the stovetop over medium-low heat until warmed through, or portion it into microwave-safe bowls for quick lunches.
I don't recommend freezing this soup because the milk-based broth may separate and have an odd texture once thawed. But honestly, it rarely lasts long enough in our house to worry about freezing!

Recipe Notes And Helpful Tips
- If you want a thicker, creamier soup, mash some of the potatoes with the back of your spoon or a potato masher. I sometimes do this when Emily requests "super creamy soup night."
- Feel free to add more kielbasa if you're a meat lover! My husband always sneaks in extra when he's helping with dinner.
- For a lighter version, you can substitute half-and-half or 2% milk, but the soup won't be quite as rich.
- Yellow or Yukon Gold potatoes work best in this recipe because they have a buttery flavor and hold their shape well.
- If you like a bit more heat, increase the red chili flakes or add a dash of hot sauce at the end.
- This soup pairs wonderfully with a simple green salad and crusty bread for a complete meal.
- Don't skip the step of browning the kielbasa first - it adds so much flavor to the entire dish!
