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.
