Polish Zurek Sour Rye Soup with Sausage
Polish Zurek Soup
A tangy Polish sour rye soup simmered with smoked sausage, potatoes, marjoram, cream, and served with a boiled egg.
Polish zurek is a deeply savory sour rye soup with a gentle tang from fermented rye starter. It is especially loved around Easter, but it belongs just as comfortably at the table on a cold weeknight, when smoky sausage, potatoes, and a spoonful of cream make the bowl feel complete.
This version uses prepared sour rye starter, which is the easiest way to get the right flavor without beginning several days ahead. Smoked kielbasa gives the broth body, while onion, garlic, bay leaf, allspice, and marjoram build the familiar Polish aroma that balances the sharpness of the rye.
The soup should taste pleasantly sour rather than harsh, so the starter is stirred in gradually and simmered only briefly. A little sour cream softens the edge, and the boiled egg added at serving makes each bowl rich enough to stand as the main meal.
Serve zurek hot with rye bread on the side. If your starter is very thick or strong, shake it well, add part of it first, and adjust near the end so the soup stays balanced.

Directions
-
1
Place the eggs in a small saucepan, cover with water, and bring to a boil. Turn off the heat, cover, and let stand for 10 minutes, then cool, peel, and halve them.
-
2
Brown the sliced kielbasa in a large soup pot over medium heat for 4 to 5 minutes, until the edges are lightly crisp. Transfer the sausage to a plate and leave the rendered fat in the pot.
-
3
Add the butter and onion to the pot. Cook for 5 minutes, stirring often, until the onion is soft, then stir in the garlic for 30 seconds.
-
4
Pour in the chicken broth, scraping up any browned bits. Add the potatoes, bay leaves, allspice, marjoram, and a small pinch of salt.
-
5
Bring the soup to a steady simmer and cook for 15 to 18 minutes, until the potatoes are tender but not falling apart.
-
6
Shake the sour rye starter well, then stir in 1 1/2 cups of it. Simmer gently for 5 minutes, tasting before adding the remaining starter if you want a sharper sour flavor.
-
7
Whisk the sour cream with a ladleful of hot soup in a small bowl, then stir it back into the pot along with the horseradish. Keep the soup below a boil so the cream stays smooth.
-
8
Return the kielbasa to the pot and simmer for 3 minutes. Remove the bay leaves and allspice berries, then season with salt and black pepper.
-
9
Ladle the soup into bowls and top each serving with a boiled egg half and chopped dill.

Tips & Notes
- Prepared sour rye starters vary in strength, so add most of it first and adjust the final amount after tasting.
- Do not boil the soup after adding sour cream; gentle heat keeps the broth velvety.
- For a stronger Polish deli flavor, use white kielbasa or a mix of smoked kielbasa and ham.
