Why This Recipe Works
This Kielbasa Potato Soup is one of my favorite cozy soups to make when the weather turns cold. Here’s why I keep coming back to it:
- Smoky and Savory: Browning the kielbasa first adds layers of deep, smoky flavor that infuses the whole soup. It’s the kind of base that makes people ask for seconds. The flavors are as rich as in my Air Fryer Kielbasa.
- Creamy Without Being Too Heavy: Thanks to the mix of milk and cream, this soup has a rich texture without feeling too rich. It’s perfectly balanced, a lot like my Creamy Chicken and Rice Soup.
- Leeks Add Something Special: Sautéed leeks give the soup a sweet, mellow onion flavor that’s just different enough to feel elevated.
- Great for Leftovers: This soup keeps well in the fridge and the flavors get even better the next day. I always make a big batch and save half for later.
- Fresh Dill Makes It Pop: That sprinkle of fresh dill at the end adds brightness and contrast. It’s the final touch that brings everything together.

Ingredients
- Kielbasa Sausage – Smoky, savory, and rich, kielbasa adds a hearty, meaty flavor that runs throughout the soup.
- Unsalted Butter – Helps sauté the leeks and adds richness to the base. Using unsalted butter gives you better control over the final seasoning.
- Leeks – Milder than onions, leeks bring a gentle sweetness and a soft, silky texture once sautéed.
- Garlic – Adds aromatic flavor and depth to the soup without overpowering it.
- All-Purpose Flour – Used to make a roux that thickens the broth into a creamy, velvety texture.
- Russet Potatoes – These starchy potatoes break down slightly as they cook, helping thicken the soup naturally and making it extra cozy.
- Chicken Stock – Forms the base of the soup, bringing savory flavor that ties everything together.
- Whole Milk – Adds creaminess without being too heavy. Balances the richness of the cream and sausage.
- Heavy Cream – Makes the soup luxuriously rich and smooth. Just a cup is enough to elevate the entire bowl.
- Fresh Dill – Sprinkled on top right before serving, it adds brightness and a fresh herbal contrast to the creamy, smoky base.

Instructions
- Brown the kielbasa: Heat olive oil in a large pot over medium heat. Add sliced kielbasa and cook until golden on both sides, about 5 minutes. Remove with a slotted spoon and set aside.
- Sauté aromatics: Melt butter in the same pot. Add leeks and cook until softened, about 5 minutes. Stir in garlic and cook for 1 more minute.
- Add potatoes and broth: Sprinkle flour over the leeks and stir to coat. Add cubed potatoes, then slowly pour in the chicken stock while stirring.
- Cook until fork tender: Bring the soup to a simmer and cook for 12–15 minutes, or until the potatoes are fully cooked and easy to pierce.
- Add milk and cream: Stir in the milk, heavy cream, and salt. Simmer gently for 5 minutes to heat through without boiling.
- Stir in kielbasa: Return the browned kielbasa to the pot and simmer for 2 minutes to warm through.
- Garnish with Dill: Sprinkle the soup with fresh chopped dill for a burst of flavor.
- Serve: Ladle into bowls and enjoy warm with crusty bread on the side.

Substitutions & Variations
Here are some of my favorite substitutions and variations:
- Kielbasa Options: I usually use smoked pork kielbasa, but turkey kielbasa or beef sausage work just as well. You can even try a spicy sausage if you want a little heat.
- Potato Swaps: Russet potatoes break down a bit and add creaminess, but Yukon Gold or red potatoes hold their shape better. Use whatever you have on hand.
- Add-In Ideas: Stir in a handful of baby spinach or kale at the end for extra greens. You can also add corn, white beans, or shredded cheddar cheese for more heartiness.
What to Serve with Kielbasa Potato Soup
Breads
- We love a good crusty side with this soup. Try it with my Homemade Focaccia or a warm slice of no knead dutch oven bread to mop up the creamy broth.
- For something extra indulgent, pair it with a grilled cheese sandwich or buttery garlic parmesan rolls.
Sides
- A big bowl of this creamy kielbasa potato soup deserves a side that adds contrast in texture. These Zucchini Fritters are lightly crispy on the outside and tender inside, and go great with it.
- These Air Fryer Carrots bring a natural sweetness and caramelized edges that balance the smoky sausage and rich broth.
FAQs
Can I make this soup thicker?
Yes. For a thicker soup, mash a few of the cooked potatoes right in the pot before adding the dairy. It gives the soup more body without needing extra flour.
What can I substitute for leeks?
You can use a yellow onion, shallots, or even a combo of both. They’ll give you that savory base, though leeks are milder and slightly sweeter.
How long does it last in the fridge?
Let it cool completely, then store in an airtight container for up to 4 days. Reheat on the stove over medium heat and stir often so the dairy doesn’t separate.

Kielbasa Potato Soup
Servings: 6 servings
This Kielbasa Potato Soup is my go-to when I want something hearty, creamy, and totally comforting. It’s loaded with tender potatoes, smoky sausage, and rich broth. I love serving it with crusty bread on cold nights.
Ingredients
- 1 tablespoon olive oil
- 14 oz kielbasa, sliced into half-moons
- 2 tablespoons unsalted butter
- 2 large leeks, large, white and light green parts, thinly sliced
- 4 cloves garlic, minced
- ¼ cup all-purpose flour
- 2 pounds russet potatoes, peeled and cut into ½-inch cubes
- 4 cups chicken stock
- 1 cup whole milk
- 1 cup heavy cream
- 2 teaspoon kosher salt, plus more to taste
- 2 tablespoons fresh dill, finely chopped, for serving
Instructions
- Add the olive oil and sliced kielbasa to the pot and cook until lightly browned on both sides, about 5 minutes. Remove with a slotted spoon and set aside.
- Add the butter to the pot. Once melted, stir in the leeks and cook until softened, about 5 minutes. Add the garlic and cook for 1 more minute.
- Sprinkle the flour over the leek mixture and stir to coat. Cook for 1-2 minutes to remove the raw flour taste.
- Stir in the cubed potatoes, then slowly pour in the chicken stock while stirring. Bring to a simmer and cook until potatoes are tender, about 12-15 minutes. Taste the potatoes to make sure they are fully cooked.
- Stir in the milk, heavy cream, and salt. Simmer gently for 5 minutes to heat through. Do not boil.
- Return the cooked kielbasa to the pot, stirring to combine. Simmer for an additional 2 minutes. Adjust your seasoning if needed.
- Ladle into bowls and garnish with fresh dill. Serve while hot with crusty bread.
Notes
- Brown the kielbasa first to enhance its smoky flavor and add richness to the base of the soup.
- Slice the leeks thinly and clean them thoroughly, as they often contain dirt between the layers.
- Cook the flour for 1 to 2 minutes after adding it to the leeks to eliminate the raw flour taste and help thicken the soup.
- Cut the potatoes into evenly sized 1-inch cubes so they cook at the same rate and give the soup a consistent texture.
- Stir the broth in slowly while mixing to avoid lumps and help the roux thicken properly.
- Serve with crusty bread, biscuits, or a green salad for a complete and hearty meal.
- Leftovers can be stored in the refrigerator for up to 4 days. Reheat gently on the stovetop.
- This soup does not freeze well due to the cream, which may separate when thawed. For freezer-friendly prep, omit the dairy and add it fresh when reheating.
