Instructions
5 steps- 1
In a large pot, bring the broth to a gentle simmer over medium heat, then add the sliced white kielbasa and cook for 20 minutes until the sausage is firm and has infused the broth with smoky flavor.
- 2
Whisk the zur sourdough starter thoroughly to recombine any settled flour, then slowly stream it into the simmering broth while stirring constantly to prevent curdling.
- 3
Add the minced garlic and dried marjoram, then reduce the heat to low and simmer uncovered for 25 minutes, stirring occasionally, until the soup thickens slightly and the sourness mellows into a balanced tang.
- 4
Temper the heavy cream by whisking a ladleful of hot soup into it, then pour the mixture back into the pot and stir gently; do not let it return to a hard boil or the cream may break.
- 5
Season with salt and freshly ground black pepper to taste, then ladle into bowls and top each serving with two halves of hard-boiled egg and a few extra rounds of sausage.

Listahan cooking guide
Chef notes & practical guide
Technique notes, ingredient swaps, serve-alongside ideas, storage guidance, and equipment for this recipe.
Cultural context
Zurek is one of Poland's classic sour soups, built around zur, a fermented rye starter that gives the broth its tang and slight body. It is strongly associated with Easter tables, especially when served with white kielbasa and hard-boiled eggs, but it also shows up as everyday cold-weather food because the base is practical, filling, and pantry-minded.
Listahan note
This version keeps the soup focused: tangy rye starter, sausage-infused broth, garlic, marjoram, cream, and eggs. The main job is control, adding the zur slowly and keeping the cream gentle so the soup stays smooth instead of harsh or broken.
Technique cues
- Whisk the zur before measuring or pouring it in. Rye flour settles heavily, and an unshaken starter can make the first ladles thin and the last ladles overly thick.
- Keep the soup at a simmer after the zur goes in. A hard boil can make the texture rough and push the sourness forward before it has time to settle into the broth.
- Marjoram is not just a garnish here; it is the herb that makes the sausage, garlic, and sour rye taste like zurek rather than a generic creamy soup.
Kitchen flow
- Parallel prep
- Hard-boil the eggs while the sausage simmers, then cool and halve them while the soup thickens.
- Make-ahead
- Simmer the broth, sausage, zur, garlic, and marjoram ahead, then add the tempered cream when reheating.
- Leftover move
- Spoon leftover soup over boiled potatoes or rye bread croutons for a more filling second bowl.
- Cleanup rhythm
- Rinse the whisk and ladle after the zur step, before the rye starch dries into a paste.
Ingredient brief
Role, handling, and swap guidance for each key ingredient.
Zur (fermented rye sourdough starter)
Sour base
Purpose: It gives zurek its signature tang, pale body, and fermented grain flavor.
Handling: Whisk it thoroughly before adding, then stream it in slowly while stirring the broth.
Adaptation: A bottled Polish zurek starter is the closest shortcut; a homemade rye starter will vary in sourness, so add it gradually and taste.
Fresh white kielbasa
Sausage backbone
Purpose: It seasons the broth as it simmers and gives each bowl a hearty, traditional bite.
Handling: Slice into even rounds so the pieces warm through at the same pace and are easy to portion.
Adaptation: Smoked kielbasa gives a deeper, saltier profile, while cooked Polish sausage shortens the simmering time.
Beef or vegetable broth
Soup foundation
Purpose: It carries the sour rye flavor and keeps the soup from tasting thin.
Handling: Bring it to a gentle simmer before adding the sausage so the broth starts extracting flavor right away.
Adaptation: Beef broth makes the bowl richer; vegetable broth keeps the sour rye and marjoram more prominent.
Hard-boiled eggs
Serving garnish
Purpose: The yolks soften the tang of the soup and make the bowl feel complete.
Handling: Halve them just before serving so the yolks stay neat and do not cloud the pot.
Adaptation: Quartered eggs are easier to eat with a spoon if you want smaller bites in each bowl.
Heavy cream
Smooth finish
Purpose: It rounds the acidity of the zur and gives the soup a softer texture.
Handling: Temper it with hot soup before adding it back to the pot, then keep the heat low.
Adaptation: Sour cream gives a sharper, more traditional-tasting finish, but it needs the same gentle tempering.
Dried marjoram
Herbal seasoning
Purpose: Its warm, slightly woodsy flavor is a key Polish note with kielbasa and garlic.
Handling: Rub it lightly between your fingers before adding so it wakes up in the hot broth.
Adaptation: Use a smaller amount of dried oregano only as a backup; it is stronger and less rounded than marjoram.
Technique notes
- Taste before salting. Kielbasa and broth can already bring plenty of seasoning, and reducing the soup concentrates it further.
- Add the cream off a hard boil. The soup should be hot enough to blend smoothly, not so hot that the dairy turns grainy.
- Serve the eggs in the bowl, not stirred through the pot. They look cleaner, hold their texture, and let each person get a good yolk-rich spoonful.
Ingredient swaps
- Richer holiday bowl
- Use beef broth and a spoonful of sour cream in place of some of the heavy cream for a deeper, sharper finish.
- Lighter broth profile
- Use vegetable broth and let the marjoram and garlic carry more of the aroma.
- Potato addition
- Add small boiled potato cubes to the bowls before ladling in the soup; they soak up the tang without making the pot starchy.
- Sausage shortcut
- Use fully cooked kielbasa and simmer it briefly in the broth before adding the zur, just long enough to season the liquid.
Serve alongside
- Rye bread with butter
- Boiled dill potatoes
- Cucumber salad with sour cream
- Pickled beets

Storage & reheating
- Refrigerate the soup and egg halves separately in sealed containers so the eggs stay tidy.
- Reheat the soup gently over low heat, stirring often and avoiding a hard boil after the cream has been added.
- Freeze the soup before adding cream for the best texture, then thaw overnight and finish with tempered cream as it reheats.
Equipment
- Large heavy pot
- Whisk
- Ladle
- Small saucepan for eggs
