Zurek is arguably the most uniquely Polish soup there is, built on zakwas, a rye-flour starter that gives the broth its signature sour tang. The name comes from zur, from an old Germanic root meaning sour, and that gentle, earthy sourness, closer to sourdough than to lemon, is the whole point of the dish.
The starter is soured over several days, then whisked into a smoky meat broth with biala kielbasa (fresh white sausage), smoked bacon, root vegetables, garlic, and a generous hand of marjoram, the herb Poles consider the soul of the soup. A little cream is tempered in at the end for body.
It is the classic Polish Easter soup, sometimes served in a hollowed-out bread bowl, but it is eaten all year in colder months. Each bowl is crowned with a halved hard-boiled egg and slices of sausage, with crusty rye bread alongside to soak up every tangy, smoky drop.

Ingredients
US
Metric
Serves 6
2 cups soured rye starter (zakwas), stirred well
7 cups meat (chicken or beef)
1 lb white sausage (biała kiełbasa)
5 oz smoked bacon, diced
1 lb potatoes, peeled and cubed
1 each carrot and parsnip, cubed
1 onion, 3 cloves onion, chopped, and garlic, crushed
1 tbsp dried marjoram
2 bay, 4 allspice bay leaves and allspice berries
1/3 cup sour cream, to finish
3 hard-boiled eggs, halved, to serve
Instructions
1
Simmer the stock with the diced bacon, bay, and allspice for 10 minutes, then add the potatoes, carrot, parsnip, and onion and cook until the vegetables are tender, about 20 minutes.
✎ Chef’s note
A gentle simmer keeps the broth clear; a hard boil clouds it and can split the sausage later.
2
Add the white sausage whole and poach gently for about 15 minutes until cooked through, then lift it out, slice into thick rounds, and return it to the pot.
✎ Chef’s note
Poaching the sausage rather than boiling keeps it from bursting.
3
Stir the soured rye starter well (the flour settles), then whisk it slowly into the soup so it stays smooth. Add the crushed garlic and marjoram, rubbing the marjoram between your palms first, and simmer gently for 10 minutes.
✎ Chef’s note
Marjoram is the soul of zurek; do not skip it, and add it near the end so its aroma survives.
4
Temper the sour cream by whisking in a ladle of hot soup, then stir it back into the pot and warm through without boiling. Season with salt and pepper.
5
Ladle into bowls and crown each with a halved hard-boiled egg and a few slices of sausage. Serve with crusty rye bread, or in a hollowed bread bowl for the full effect.
Polish Easter tradition.

📍
Lesser Poland. Krakow's other protected food is the obwarzanek krakowski, the plaited ring boiled before it is baked, which has held a protected geographical indication since 2010 and is sold from blue carts on the street corners. Pierogi are argued over rather than owned here: the origin stories run to Kyiv, Central Asia and the Middle East as well as to Krakow, but the city holds the loudest claim and an annual festival.
🗺️
Poland. Wigilia, the Christmas Eve supper, is the year's set piece: no meat, twelve dishes for the twelve Apostles, and nobody sits down until someone spots the first star. Beetroot barszcz with mushroom-filled uszka opens it, carp in several guises follows, and kutia of barley, poppy seed and honey brings it to a close.
🌍
Europe. Europe has written a great deal of its food into law. A regulation of 1992 created the protected designation of origin and the protected geographical indication, tying a name to a place and a method, and an EU evaluation published in 2021 counted more than three thousand registered names across those schemes, from cheeses and hams down to particular shapes of bread.
The story behind this dish is up top, worth a read while the pot works.
