Polish Sour White Sausage Soup
Polish sour white sausage soup turns humble white sausage, potatoes, fermented wheat starter, and eggs into a creamy, tangy, deeply comforting bowl.
This classic soup is hearty without feeling heavy. The broth tastes savory and slightly sharp, the potatoes make it filling, and the marjoram gives it that old world Polish kitchen aroma.
Why You’ll Love This Recipe
- It tastes rich, tangy, savory, and cozy with simple ingredients.
- The potatoes and eggs make each bowl filling enough for dinner.
- Fermented wheat starter gives the broth a bright sour flavor without extra work.
- It cooks in one pot, so cleanup stays simple.
Fabian’s Budget Tip: Use homemade broth from chicken bones or vegetable scraps if you have it. If Polish white sausage costs more in your area, use half sausage and add one extra potato. You still get a flavorful, satisfying soup for less.
Ingredients (Serves 4)
- 1 pound (450 g) Polish white sausage, fresh or smoked
- 6 cups (1.4 L) chicken broth or vegetable broth
- 1 1/4 pounds (570 g) potatoes, peeled and cut into bite size chunks
- 1 medium onion (150 g), finely chopped
- 3 garlic cloves (9 g), minced
- 1 to 1 1/2 cups (240 to 360 ml) fermented wheat starter, shaken well
- 1 teaspoon (1 g) dried marjoram, rubbed between your fingers
- 1 tablespoon (15 g) prepared horseradish, plus more to taste

- 1/2 teaspoon (1 g) black pepper, plus more to taste
Step-by-Step Instructions
1. Simmer the Sausage
Add the broth and white sausage to a large soup pot. Bring it to a gentle simmer over medium heat. Cook for 15 minutes, until the broth smells savory and the sausage feels firm when touched with tongs.
2. Add the Potatoes, Onion, and Garlic
Lift the sausage onto a plate and set it aside. Add the potatoes, onion, and garlic to the broth. Simmer for 15 to 18 minutes, until the potatoes are tender and the onion softens into the soup. The kitchen should smell sweet from the onion and warm from the garlic.
3. Slice the Sausage
Slice the cooked sausage into thick rounds. Return the slices to the pot. Let them simmer for 3 to 5 minutes so the edges turn plump and the broth picks up more sausage flavor.
4. Stir in the Sour Starter and Marjoram
Shake or stir the fermented wheat starter well, then pour in 1 cup (240 ml) while stirring the soup. Add the marjoram and simmer gently for 5 minutes. The broth should turn lightly cloudy, creamy looking, and pleasantly tangy. Taste it before adding more starter.
5. Add Horseradish and Seasoning
Stir in the horseradish, salt, and black pepper. Start with the listed amount, then taste. The soup should feel bright, savory, and peppery, with a gentle heat from the horseradish.
6. Temper the Sour Cream
Spoon the sour cream into a small bowl. Whisk in a ladle of hot soup until smooth. Pour this mixture back into the pot while stirring. Keep the heat low and do not boil, so the soup stays silky instead of grainy.
7. Serve with Eggs
Place two egg halves in each bowl. Ladle the hot soup over the eggs, making sure every serving gets sausage, potatoes, and creamy broth. Add extra black pepper or horseradish if you like a sharper finish.
Expert Troubleshooting & FAQs
Why did my sour cream curdle?
The soup was likely too hot when the sour cream went in. Temper it first with hot broth, then stir it into the pot over low heat. Do not let the soup boil after adding sour cream.
How sour should Polish sour white sausage soup taste?
It should taste tangy but balanced. Start with 1 cup (240 ml) fermented wheat starter, then add more if you want a sharper broth. Different starters vary in strength.
Can I use smoked sausage instead of fresh white sausage?
Yes. Smoked Polish sausage gives the soup a deeper, smoky flavor. Fresh white sausage tastes milder and more traditional. Both work well.
What if I cannot find fermented wheat starter?
Look for Polish żur starter in Eastern European grocery stores. Rye starter can also work, though the flavor will be a bit deeper and earthier.
Can I make this soup ahead?
Yes. Make the soup without the eggs, cool it, and refrigerate it for up to 3 days. Reheat gently over low heat, then add fresh hard boiled eggs when serving.
