What Is Polish Sauerkraut Soup (Kapusniak)?

- 400 g (1 lb) sauerkraut, drained

How to Make Polish Sauerkraut Soup
Follow these simple steps to create a flavorful and comforting pot of Kapusniak.
Step 1: Sauté Vegetables
Start by heating the sunflower oil in a large stockpot or Dutch oven over medium heat. Once the oil is hot, add the onion and sauté it for 2-3 minutes until it softens. This will form the flavorful base of your soup. Add the leek, carrot, and parsnip to the pot and continue cooking for another 8-10 minutes, stirring occasionally, until the vegetables become tender.
Step 2: Add Garlic and Spices
Next, stir in the garlic, caraway seeds, marjoram, allspice, juniper berries, and bay leaves. Continue cooking for an additional 1-2 minutes, allowing the spices to release their flavors and aroma. The combination of these spices is what gives Kapusniak its distinctive, savory flavor.
Step 3: Add Sauerkraut and Simmer
Add the sauerkraut to the pot and cook it with the vegetables for another 1-2 minutes. Then, pour in a ladle of vegetable stock and let it simmer for 10 minutes to bring all the flavors together. The sauerkraut will soften and infuse the broth with its tangy flavor, creating a rich, savory base for the soup.
Step 4: Add Potatoes and Cook
Now it’s time to add the potatoes and the remaining vegetable stock. Bring the mixture to a boil, then reduce the heat to low. Let the soup simmer for about 25 minutes, or until the potatoes are fork-tender. The potatoes will help thicken the soup, making it hearty and filling.
Step 5: Season to Taste
Once the potatoes are tender, taste the soup and season it with salt and freshly ground pepper according to your preference. This is the final step to ensure the soup has the perfect balance of flavors.
Step 6: Serve and Enjoy
Ladle the Polish Sauerkraut Soup into bowls and serve hot with a side of rye bread or your favorite crusty bread. The bread complements the soup’s tangy flavor and helps soak up the rich broth, making it the perfect comfort meal.
