Polish Sour Rye Żurek

Section: Comforting Soups and Hearty Stews

Żurek is a cherished Polish soup made with a naturally fermented rye starter, which gives it a signature tangy flavor and creamy body. White sausage, dried mushrooms, garlic, and marjoram combine to create a deeply savory broth, which is balanced with a touch of cream for smoothness. Traditionally enjoyed at Easter but beloved year-round, Żurek is typically served with boiled potatoes and hard-boiled eggs, garnished with fresh herbs for a fragrant finish. The success of this bowl lies in a lively sour taste offset by the rich sausage and notes of earthy mushroom. Seek out a quality sourdough starter for true flavor—bottled versions can also be found at Polish grocery shops.

Polish Sour Rye Soup Żurek brings together tangy rye, savory sausage, and aromatic herbs for a bowl that is truly comforting. This traditional dish has been offered at Polish Easter tables for generations but I find myself craving it no matter the season. It is satisfying enough for dinner yet special enough to serve for a holiday meal.

Żurek was the first soup I made for my Polish in-laws. I was so nervous trying to get the right level of sourness and richness but their smiles told me I got it just right.

Ingredients

  • White baked sausage: Popularly called Polska biała kiełbasa this mild sausage is key for the soup’s hearty depth. Select fresh uncooked sausage from a Polish deli if possible for best results
  • Dried bay boletes or porcini mushrooms: Add earthiness and umami. Look for whole dried mushrooms that are fragrant and free of dust for maximum flavor
  • Bay leaves: Fragrant and subtly bitter. Choose leaves that are pliable and green rather than broken or faded
  • Whole allspice grains: Give the soup an aromatic backdrop. Crush them lightly with the back of a spoon
  • Fresh garlic: Adds pungency and complexity. Use plump firm cloves
  • Sourdough rye starter: Provides the signature tangy taste. Homemade is best but store-bought in glass bottles works too Seek one with a smooth sour aroma
  • Marjoram: Classic in Żurek Choose dried leaves that are green and aromatic not brown and stale
  • Salt: Brings all the flavors together. Try flake salt or fine sea salt for ease of seasoning
  • Heavy cream: Gives a creamy smooth texture. For best taste use cream with at least 30 percent fat

To Serve

  • Boiled potatoes: Earthy and satisfying. Choose waxy potatoes that will hold their shape
  • Hard-boiled eggs: Traditional garnish Their rich yolks add creaminess
  • Fresh marjoram: Optional A sprinkle at the end lifts the whole bowl

Step-by-Step Instructions

Prepare the Broth:
Gently place the white sausages in a large pot with cold water Cover and bring to a gentle simmer Skim off any foam and cook until the sausages are just tender about 25 minutes Remove sausages and set aside Keep the flavorful cooking liquid in the pot
Layer in the Aromatics:
Drop the dried mushrooms directly into the pot No soaking is required Toss in bay leaves and allspice Season with salt Press garlic cloves and add them Stir gently Let the broth simmer for another 10 minutes so the aromatics have time to infuse
Return the Sausage:
Slice the cooked sausages into coins Add them back into the simmering broth Allow everything to cook together over low heat for 15 minutes so the sausage flavor blends fully with the broth
Add the Rye Starter:
Give your sourdough rye starter a good shake to mix Pour it gently into the soup Stir in the dried marjoram Taste the soup you should feel a delicate tang Add more salt if needed Warm the soup through over medium heat but avoid bringing it to a strong boil or the sourness can become harsh
Temper and Add the Cream:
Pour your cream into a bowl Slowly whisk in a few ladlefuls of hot soup to raise its temperature This prevents curdling Return the warmed cream mixture to the pot and stir until the soup is creamy and slightly thickened Gently bring to just below a boil
Serve with Potatoes and Eggs:
Spoon the Żurek into deep bowls Add a mound of boiled potatoes and a halved hard-boiled egg to each bowl Garnish with fresh marjoram for a fragrant finish Serve piping hot

Homemade rye starter truly makes the difference in flavor I once made Żurek just with water and vinegar as a shortcut It was never quite right Later I waited three days for a rye flour-and-water starter and that tang blew me away My grandmother always reminded me that patience equals real character in soup

Storage Tips

Żurek stores beautifully Once cooled cover and refrigerate for up to four days The sourness is more pronounced after a night or two Simply reheat gently on the stovetop If you wish to freeze the soup leave out the potatoes and eggs and add them fresh when you reheat

Ingredient Substitutions

If you cannot find Polish white sausage try a mild raw pork sausage and add majoram for the classic flavor For a vegetarian version leave out the sausage and add cubed smoked tofu or more mushrooms Scallions or dill can work as a fresh garnish in a pinch

Serving Suggestions

Though traditionally served with potatoes and eggs you can try Żurek with crusty rye bread or even a swirl of horseradish It also pairs well with a side of beet salad or sauerkraut for a layered meal

Steps to Follow

Step 02

Add dried porcini mushrooms, bay leaves, allspice berries, and salt to the sausage cooking broth. Crush and add garlic cloves, then simmer for another 10 minutes to extract fullness of aroma.

Step 03

Slice the cooked sausages into thick pieces and return them to the pot. Cover and simmer for 15 minutes to allow flavors to blend.

Shake the rye sourdough starter well, pour it into the soup, and stir in dried marjoram. Heat gently, avoiding boiling, for several minutes to develop the signature sour flavor.

Ladle a small amount of hot soup into the cream to temper, stirring constantly. Slowly add the tempered cream back into the pot. Bring to a gentle boil while stirring to emulsify without curdling.
