Ingredients
  • sauerkraut, roughly chopped 300g
  • potatoes, peeled and diced 2 medium
  • carrot, grated 1 medium
  • onion, finely diced 1 medium
  • garlic, minced 2 cloves
  • tomato paste 1 tbsp
  • olive oil 1 tsp
  • vegetable stock (low-sodium) 1 litre
  • bay leaf 1
  • caraway seeds ½ tsp
  • salt and black pepper to taste
  • fresh parsley, to serve 2 tbsp
Method
  1. 1

    Heat olive oil in a large pot over medium heat. Add onion and carrot. Cook 6–8 minutes until softened and beginning to caramelise.

  2. 2

    Add garlic and tomato paste. Stir and cook for 1 minute.

  3. 3

    Add sauerkraut, potatoes, bay leaf, and caraway seeds. Pour in the stock.

  4. 4

    Bring to a boil, then reduce heat. Simmer partially covered for 25 minutes until potatoes are tender and sauerkraut is soft.

  5. 5

    Remove bay leaf. Taste and season — sauerkraut is already salty so add salt carefully.

  6. 6

    Serve in deep bowls with fresh parsley. Improve overnight in the fridge.

💡 Natali's tip: Rinse the sauerkraut if you want a milder flavour, or use it straight from the jar for maximum tang and probiotics.

Kapustnyak is the soup that Eastern European grandmothers made to get through winter. Sauerkraut — fermented white cabbage — is one of the most underrated ingredients in European cooking: probiotic-rich, almost zero calories, and it gives this soup an extraordinary depth of flavour that no fresh vegetable can replicate.

At 175 calories for a large bowl, this is one of the most filling, satisfying soups in the Eastern European repertoire.

Frequently asked questions

Should I rinse the sauerkraut first?

Taste it first. Rinse only if it's very sharp — the brine carries much of the flavour that makes kapustnyak distinctive.

Can I add meat?

Traditional versions use pork or sausage. Lean turkey kielbasa adds the smoky note while keeping the bowl light.

Does it freeze well?

Yes, up to 3 months. The potatoes soften slightly on thawing but the flavour holds.
