Polish Żurek – Sour Rye Soup

Żurek, often referred to as Polish Zurek Soup, stands as a cherished traditional dish in Poland, especially during the Easter holiday. Personally, it ranks among my top favourites. While its preparation varies from one region to another and even between households, the essence of its rich and unique flavour remains consistent, thanks to the fermented rye starter that serves as its cornerstone ingredient. After your first taste of this delightful soup, I’m confident you’ll share my deep appreciation for it.

Now, if you’re keen on crafting your own Polish Zurek Soup, the journey begins with the preparation of the starter. Although this step is simple and demands minimal upkeep, patience is key, as the fermentation process spans roughly 5-7 days. Of course, for those short on time, there’s always the option to buy a ready-made Zurek base. However, I must emphasize that nothing quite matches the taste of a homemade batch.

  • Distinctive Taste: No other soup can match its unique flavour.
  • Starter Dedication: While the preparation demands patience, the end result is undeniably rewarding.
  • Authentic Experience: Embracing the traditional process offers a genuine taste of Polish heritage.

Żurek: Traditional Polish Sour Rye Soup Explained

Introduction to Żurek

Żurek, a traditional sour rye soup, holds a special place in the hearts of the Polish people. Originating from the unique tang of fermented rye flour starter, known as “żur”, this soup combines the robust flavours of potatoes, sausage, bacon, eggs, and aromatic herbs.

A Glimpse into the Past: The History of Żurek

Tracing its roots back to the Middle Ages, Żurek served as a staple for peasants and workers. They crafted this soup as a clever means to utilize leftover ingredients, maximizing the scarce resources at hand. Over time, its popularity surged, making it a cherished dish across all age groups and social strata.

Regional Twists: Variations Across Poland

In the diverse regions of Poland, Żurek takes on various delightful forms. For instance, in Silesia, the locals prefer adding white sausage and hard-boiled eggs. Meanwhile, the Kashubians opt for fish over meat. The folks in Wielkopolska infuse their Żurek with marjoram and garlic. And in Krakow, my beloved hometown, we have a unique tradition of serving it in a hollowed-out bread bowl.

A Chef’s Perspective: Experimenting with Żurek

Being a chef, I constantly play around with the classic Polish Żurek Soup recipe. On some occasions, I incorporate mushrooms or diverse vegetables, enhancing its heartiness. At other times, a dollop of sour cream or a slice of oven-fresh bread complements the soup perfectly.

Conclusion: A Must-Try in Poland

If your travels ever take you to Poland, don’t miss out on savouring this traditional soup. It’s more than just a meal; it’s an experience of history, tradition, and Polish culinary excellence. I encourage you to prepare your own as well! Smacznego!

Starter Ingredients (Sour Rye):

Ingredients for the Soup:

  • 6.3 cups Vegetable Bullion (1.5L)
  • 2.1 cups Zurek starter (500ml)
  • 4 Pork sausages, small (you can also add Polish smoked sausage – Kielbasa)
  • 8.8 oz Uncut smoked bacon (Boczek)
  • 1 tsp Marjoram
  • 3 tbsp Double Cream (soured cream works as well)
  • Salt to taste

To serve:

  • Boiled diced potatoes
  • 6 Hard-boiled Eggs cut in half
  • Sourdough Bread
  • Fresh Parsley or dill, for garnish
  • Black Pepper to taste


Instructions for Starter (Sour Rye):

  • For the starter preparation, use water free from chlorine as it can inhibit microbial growth. Boil the water and allow it to cool to room temperature before use.
  • Once the water has cooled, combine all the starter ingredients in a sanitized jar. Mix them thoroughly with a clean spoon.
  • Cover the jar with a cloth or paper towel and secure it with a band or tie. This ensures the starter has ventilation while remaining protected.
  • Position the jar in a spot shielded from direct sunlight, maintaining room temperature, mix with clean spoon every other day. In about 5-7 days, the starter should be mature and ready. You can utilize it immediately or refrigerate it for up to two weeks. If refrigerating, remember to remove and discard any spices from the starter. If using immediately, incorporate the starter into your recipe as directed.

Instructions for Vegetable Bullion (Soup Base):

  • Begin by making the vegetable broth. In a large pot, combine 1 liter of water, diced carrots, 2 medium onions (quartered), a stalk of celery (chopped), and a sliced leek. Place the pot on high heat and bring the contents to a boil. Once boiling, reduce the heat to low, allowing the mixture to simmer. Cover the pot with a lid and let it simmer for 1 hour.
  • After the broth has been simmering for an hour, carefully strain the liquid, separating it from the vegetables. Retain the carrots for inclusion in your soup, and discard the rest of the vegetables.

Instructions for Żurek Soup

  • Start by dicing the bacon. In a pan over high heat, fry the bacon for 4-5 minutes until its fat is rendered.
  • To the hot stock, add the crispy bacon, cooked carrots, sausages (whole or sliced), and 1 teaspoon of marjoram. Bring the contents to a boil, then lower the heat and let it simmer for 5 minutes.
  • Take the Żurek starter and whisk it with the sediment, ensuring to discard any spices. Gradually pour this mixture into the soup, allowing it to simmer until the consistency becomes thicker.
  • Remove the soup from the stove and extract the sausages. Once sliced, reintroduce them to the pot.
  • In a separate bowl, blend the cream with a ladleful of the soup. This process ensures the cream doesn't curdle when added to the hot soup. Once mixed, pour this creamy mixture back into the main pot.
  • To serve, ladle the Żurek into bowls. Add cooked potatoes to the soup and garnish with either parsley or dill, and a sprinkle of black pepper. Accompany with hard-boiled eggs (Zurek z jajkiem) and slices of fresh sourdough bread. Enjoy your meal! (Smacznego!)


  • Horseradish Boost: Introduce a zesty kick to your Żurek by adding 1 tablespoon of freshly grated horseradish. It not only enhances the soup’s flavour but also adds a spicy undertone that complements the tanginess of the fermented rye.
  • Mushroom Depth: Incorporate wild mushrooms, such as porcini or chanterelles, to the soup. They add a rich, earthy depth to the flavour profile, making the soup even more hearty and robust.
  • Traditional Presentation: Serving Zurek in a hollowed-out sourdough bread, known as “Zurek w Chlebie”, is not just a delightful presentation but also offers a unique taste experience. The bread soaks up the soup, providing a delightful texture contrast.
  • Herb Garnish: Fresh herbs like dill, chives, or parsley can be finely chopped and sprinkled on top before serving. They add a burst of colour and a fresh aroma that elevates the dish.
  • Storage: If you have leftovers, store the Żurek in an airtight container in the refrigerator. The flavours tend to meld and intensify, making it even more delicious the next day.

FAQ for Starter Preparation:

  • How can I tell if my starter is ready? The starter will emit a tangy aroma complemented by the pleasant scents of spices and garlic, and the liquid will separate from the solids.
  • What to do when foam appears on the surface of the starter? A light foam may appear on the surface of the starter. This is natural in the fermentation process. You can remove the foam from the surface of the starter every other day. However, if mold appears and the starter doesn’t smell good, it should be discarded. The most common cause of mold is contamination of the starter during mixing. Very often, the cause of the starter spoiling can also be a not thoroughly cleaned container or poor air access during the fermentation process.
  • Is it normal for the starter to have a strong smell? Yes, a tangy or sour smell with aroma of garlic and spices is normal. However, if it smells unpleasant or mouldy, it’s best to discard it and start fresh.
  • What should I do if my starter isn’t fermenting? Ensure it’s kept in a warm place. If there’s still no activity after a few days, it might be best to begin a new batch.
  • How should I store the starter? If you don’t plan to make Żurek right after fermenting, don’t put the jar in the fridge immediately. First, you need to remove the garlic, bay leaves, and allspice from the starter. A fine mesh strainer might be helpful for this. Pour the starter along with the flour into a bottle or jar and keep it in the fridge for up to 2 weeks.
