What Is Czech Zelňačka?

Zelná polévka, or zelňačka is a type of traditional Czech soup made from fermented cabbage (sauerkraut, kysané zelí). The soup also includes klobása, a special Czech smoked sausage, onions and potatoes.

Back in the old days, the soup used to be cooked in winter, especially in poorer Czech regions.

Zelňačka is loaded with vitamins and other nutrients. They helped people to survive long and cold winters, which were commonplace in the Czech Republic in the past.

Sauerkraut in the Czech Republic

My family comes from the foothills of the Giant Mountains (Krkonoše), the highest mountain range in the Czech Republic. I now live about 100 km further west, in another mountainous area, the Jizera Mountains (Jizerské hory).

At the foot of the Czech mountains, the two most common crops that were planted there were cabbage and potatoes. There were ideal growing conditions for them.

In autumn, most of the cabbage yield was fermented and processed into sauerkraut. It lasted through the entirety of the winter, and sauerkraut was a good source of vitamins when the Czech people had no fresh fruit or vegetables.

Sauerkraut, kysané zelí

Genuine sauerkraut contains a lot of vitamin C and other nutrients. Sauerkraut is mostly used as a side dish (do you know the typical Czech meal called knedlo, vepřo, zelo?) or it is used in sauerkraut soup called zelňačka.

Sidenote: The word Sauerkraut is German in origin – kraut is cabbage, sauer means sour. The word Sauerkraut spread to English-speaking countries due to the German soldiers marching through Europe in both World Wars.

What Ingredients Do We Need in Zelná Polévka

Zelňačka is a healthy soup, flavored with traditional Czech herbs and spices, which used to grow in our grandmas’ gardens. You’ll need:

  • Fermented cabbage (sauerkraut)
  • Onions
  • „klobása“, a Czech smoked sausage (or polish kielbasa)
  • Potatoes
  • Lard
  • Crushed caraway seeds
  • Bay leaves
  • Pepper
  • Sweet peepers
  • Sugar
  • Chicken broth
  • All-purpose flour to thicken

A scoop of sour cream will help give zelná polévka a smoother taste.

How to Make Czech Sauerkraut Soup?

The recipe for zelňačka is easy, you just need to follow these steps:

Why to Cook the Potatoes for Zelňačka Separately?

Potatoes cooked together with sauerkraut don’t soften at all. It’s more convenient to cook the potatoes for this soup in a separate pot.

Don’t cook the potatoes until completely soft. When you add them into the soup, they will continue cooking and will soften.

Use non-starchy potatoes. They should be firm after cooking, al dente.
