A hearty and tangy Czech Sauerkraut Soup (Zelnacka), a traditional Eastern European classic perfect for cold days. This soup features sauerkraut, smoked sausage, potatoes, and spices for a deeply comforting flavor.

Ingredients

Scale
  • 1 tablespoon lard or oil (sunflower or vegetable oil)
  • 1 medium onion, finely chopped
  • 1 clove garlic, minced
  • 1½ teaspoons sweet paprika
  • 3 cups sauerkraut, drained but not rinsed
  • 5 cups water or low-sodium broth
  • 2 medium potatoes, peeled and diced
  • 7 oz (200g) smoked sausage, sliced (kielbasa or Czech-style klobása)
  • 1 bay leaf
  • Salt and black pepper, to taste
  • Optional: 1 tablespoon flour (for slightly thicker soup)
  • Optional: pinch of caraway seeds or marjoram

Instructions

  1. Heat oil in a soup pot over medium heat. Add onion and cook until golden. Stir in garlic and paprika for 30 seconds.
  2. Stir in drained sauerkraut, add water or broth, and bay leaf. Bring to a boil.
  3. Add potatoes and sausage. Lower heat and simmer 25–30 minutes, until potatoes are tender.
  4. Season with salt and pepper. For a thicker soup, stir in flour slurry and cook a few more minutes.
  5. Remove bay leaf and serve hot with rye bread or crusty rolls.

Notes

  • Do not rinse sauerkraut unless it is overly salty; you want to keep its natural tang.
  • Smoked sausage adds authentic flavor; substitute mushrooms for a vegetarian version.
  • For regional flair, add marjoram or caraway seeds near the end.
  • If the soup is too sour, balance it with a pinch of sugar or a splash of cream.
  • The soup tastes even better the next day after the flavors meld.
