A tangy, fermented rye-soured soup with smoked sausage, potatoes and a hard-boiled egg, often served in a bread bowl.
About This Recipe
Żurek is a real, traditional Polish dish, known as Polish Sour Rye Soup. A tangy, fermented rye-soured soup with smoked sausage, potatoes and a hard-boiled egg, often served in a bread bowl.\n\nŻurek is made from fermented rye flour called zakwas, a preservation technique dating back centuries in Polish peasant cooking, and it remains a traditional Easter Sunday dish across Poland today.\n\nThe result is a dish worth making on its own merits: it rewards patience with the technique and delivers real, specific flavor rooted in Polish home cooking, not a generic stand-in for a search term.

Pro Tips
- →
Add the fermented rye sour near the end and don't let the soup boil hard afterward, or it can separate and turn grainy.
- →
Marjoram is a signature Polish seasoning here — don't substitute other herbs if you can find it.
- →
Serve in a hollowed rye bread bowl for the classic presentation, though a regular bowl works fine too.
Variations
- •
A vegetarian version uses mushroom stock and omits the meat, relying on the tangy zakwas for depth.
- •
Some regions add horseradish for extra sharpness.
- •
White sausage (biala kielbasa) is the traditional Easter version of the sausage used here.
Storage
Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop or in the microwave with a splash of water or stock to loosen the texture.

Frequently Asked Questions
Where do I find zakwas?
Polish delis and some Eastern European grocery stores sell bottled zakwas; it can also be made at home by fermenting rye flour and water with garlic for about 5 days.
Can I substitute the sour rye base?
A mix of sauerkraut brine and buttermilk can approximate the tang in a pinch, though the flavor won't be identical.
Why did my soup curdle?
Boiling the soup too hard after adding the cream or sour base causes curdling — keep it at a gentle simmer once those are added.
