Pin It The first time I made sauerkraut soup was during a bitterly cold January when my immune system was in desperate need of reinforcement. The kitchen windows fogged as the tangy aroma filled my small apartment, and I remember thinking how something so simple could smell so complex. My grandmother's family came from Poland, and while this wasn't her exact recipe, the familiar scent of caraway and fermented cabbage transported me instantly to her tiny kitchen where I'd watch her hands work magic with humble ingredients.
Last winter, I brought a thermos of this soup to my friend's cabin weekend. We'd spent the afternoon sledding like overgrown children, and everyone gathered around the fire with steaming mugs of this tangy brew. Nobody spoke for the first few minutes as spoons clinked against ceramic and the warmth spread through cold fingers and tired bodies. My friend Mark, who claimed to hate sauerkraut, asked for the recipe before the weekend was over.
Ingredients
- Sauerkraut: Look for raw, refrigerated sauerkraut rather than shelf-stable jars for true probiotic benefits I learned this makes a dramatic difference in both flavor and health properties.
- Smoked Bacon or Kielbasa: The smokiness creates the foundational flavor, though I've made excellent vegetarian versions with smoked tofu or simply a teaspoon of smoked paprika.
- Caraway Seeds: Don't skip these seemingly minor seeds they're what gives the soup its authentic character and help make the cabbage more digestible.
- Potato: A single diced potato adds just enough body to the broth without turning it into a thick stew I prefer waxy varieties that hold their shape.
- Sour Cream: That final dollop creates a creamy swirl that mellows the tanginess in the most beautiful way.
Instructions
- Create your flavor base:
- In a large pot over medium heat, render the fat from your smoked meat until it's golden and fragrant. The kitchen will start smelling irresistible almost immediately.
- Build the aromatics:
- Add those finely chopped onions, minced garlic, and diced carrots to the pot, stirring occasionally until they soften and the onions become translucent. You'll notice the colors brightening as they release their flavors.
- Introduce the star ingredient:
- Stir in the sauerkraut and potatoes, giving everything a good toss to coat in the rendered fat and aromatics. Let them sauté briefly to mingle and get acquainted.
- Transform with liquid:
- Pour in your broth and water, then add the bay leaf, caraway seeds, black pepper, and paprika. Watch as it comes to a gentle boil before reducing to a simmer that will work its magic.
- Allow flavors to mature:
- Let the soup bubble gently for 30-35 minutes, uncovered, until the potatoes yield easily to a spoon. The broth will reduce slightly, concentrating all those wonderful tangy and savory notes.
- Finish with care:
- Fish out the bay leaf, taste for salt, and ladle the steaming soup into bowls. The final touch of fresh parsley and that cooling dollop of sour cream creates the perfect temperature and flavor balance.
Pin It The moment this soup became special to me was during recovery from a particularly nasty winter flu. My sense of taste had been completely absent for days, and this soup was the first thing I could actually taste again the tangy brightness cutting through the fog of illness. I remember sitting at my kitchen table, afternoon sun streaming through the window, nearly teary-eyed over a humble bowl of cabbage soup simply because my senses had returned.
Storage and Leftovers
This soup develops even more character overnight as the flavors continue to meld in the refrigerator. I often make a double batch specifically to have leftovers, storing portions in glass containers that won't stain from the paprika. The soup keeps beautifully for up to five days, and I've found the flavor peaks around day two when the caraway has fully infused the broth and the tanginess has mellowed just slightly.
Serving Suggestions
While I love this soup on its own, serving it alongside dark rye bread with a smear of good butter creates a meal that feels both rustic and somehow celebratory. For dinner parties, I've served small cups as a starter before a main course, garnished with tiny sprigs of dill and thin slices of radish for color. The contrast between the hot soup and cold, crisp vegetable adds an unexpected texture that guests always comment on.
Variations Worth Trying
Over the years, I've experimented with countless adaptations of this basic recipe, each bringing something unique to the table. During mushroom season, adding a handful of sautéed wild mushrooms lends an earthy depth that complements the tanginess beautifully. In summer, I sometimes stir in fresh tomatoes and dill during the last five minutes for a brighter, more seasonal version.
- For a heartier version, add a half cup of barley with an extra cup of broth, but be aware this makes it no longer gluten-free.
- Vegetarians can get excellent results using smoked salt and a tablespoon of olive oil instead of the rendered bacon fat.
- For special occasions, a splash of dry white wine added with the broth brings a subtle acidity that elevates the entire dish.
Pin It This humble soup connects me to generations of practical cooks who transformed simple, preserved ingredients into nourishing meals that sustained families through long winters. Each steaming bowl carries not just probiotics and comfort, but a kind of culinary wisdom that never goes out of style.
Recipe FAQs

Absolutely. Using unpasteurized sauerkraut provides live probiotics that support digestive health. The fermentation process creates beneficial bacteria that can help maintain a healthy gut microbiome. Avoid pasteurized varieties if you want maximum probiotic benefits.

Yes. Simply omit the smoked bacon or sausage, or substitute with smoked tofu for a similar savory depth. Use vegetable broth instead of chicken broth. The soup remains flavorful thanks to the sauerkraut, caraway seeds, and paprika.
- → How long does sauerkraut soup keep?
Store cooled soup in an airtight container in the refrigerator for up to 4 days. The flavors actually improve after a day or two. Reheat gently on the stove, adding a splash of water or broth if needed. Avoid boiling, which can affect the texture of the potatoes.

Crusty rye bread or rolls are traditional accompaniments that soak up the flavorful broth. A crisp Riesling wine or light lager pairs beautifully with the tangy, smoky notes. A simple green salad with acidic dressing provides a fresh contrast to the rich, warming soup.
- → Can I freeze sauerkraut soup?
Yes, this soup freezes well for up to 3 months. Cool completely before transferring to freezer-safe containers, leaving some space for expansion. Thaw overnight in the refrigerator and reheat gently. Note that potatoes may soften slightly after freezing, though flavor remains excellent.
