Sauerkraut Soup Recipe

What a delicious soup Czech zelňačka is! Made from sauerkraut, zelňačka (or zelná polévka z kysaného zelí) is a soul-warming soup ideal for cold autumn and winter days.

If you’re thinking of giving it a try, I want to assure you that Czech zelňačka definitely stands out from other sauerkraut soups!

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 survive long and cold winters, which were commonplace in the Czech Republic's mountainous areas in the past.

Pronunciation

I recorded a short audio clip on pronouncing the Czech word zelňačka. The first word in the audio is "zelňačka" – the name of the food, the last is "zelná polévka", which means sauerkraut soup.

MY TIP: Try out česnečka, Czech garlic soup, often used as a healing soup while being sick or as a hangover cure!

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.

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.

Ingredients

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, the hero ingredient here, aka sauerkraut
• Onions, peeled and finely chopped
• Klobása, a Czech smoked sausage (or polish kielbasa)
• Brown potatoes, peeled and diced, cooked separately
• Lard, or vegetable oil
• Caraway seeds, crushed for even better taste
• Bay leaves
• Black pepper, freshly ground
• Sweet paprika, ground, ideally Hungarian-style
• Sugar, to make the sauerkraut soup taste better
• Chicken broth, in case you don’t have broth, use water
• All-purpose flour, to thicken the zelňačka soup, we’ll use flour for a roux

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

Cook’s Tips

• You should cook potatoes and sauerkraut 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.
