This rich Polish soup brings together the sharp taste of sauerkraut with smoky pork in a deeply satisfying blend. The time-honored mountain recipe packs hundreds of years of Polish cooking tradition into each flavorful spoonful, delivering both warmth and complex tastes that get better the longer they sit.
I picked up this soup recipe from an elderly Polish woman living near the Tatra mountains who taught me that letting everything simmer unhurried is the key to getting that real, deep flavor.
Key Ingredients
- Homemade sauerkraut: Crunchy and naturally soured, skip anything canned
- Uncooked pork ribs: Pick juicy, fresh cuts for the best taste
- Smoked ribs: Look for dark, aromatic pieces
- Wild mushrooms: Well-dried and deeply colored
- Potatoes: Firm types that won't fall apart
- Fresh marjoram: Brings that classic Polish flavor note
- Caraway seeds: Use intact, fragrant seeds
- Allspice berries: Keep them whole
- Top-quality smoked bacon: Creates needed flavor foundation
Cooking Method
- Creating the Base:
- Start with cool water and your meats to slowly draw out flavors. Remove foam from top regularly for a clear soup. Look for meat starting to pull away from bones as your sign it's tender enough.
- Handling Seasonings:
- Lightly heat caraway seeds first to wake up their oils. Add each aromatic ingredient with enough time between to let their flavors mix into the broth.
- Working with Sauerkraut:
- Mix in the cut sauerkraut bit by bit, checking the sourness as you go. You want a nice tang that doesn't take over all other flavors.
- Finishing Touches:
- Add potatoes when timing is right so they cook through but stay intact. Sprinkle fresh marjoram right before you serve.

The grandma who showed me this recipe always stressed that you can't skip the caraway seeds - they're not just for the authentic taste but they also help you digest this hearty meal better.
Serving Suggestions
Dish up this country-style soup in deep, warm bowls that show off its rustic beauty. You want to see a clear but richly colored broth with soft meat chunks, perfectly done potatoes, and strands of sauerkraut throughout. Top with some fresh parsley and a bit of ground black pepper. Don't forget to offer thick slices of dark rye bread on the side - they're perfect for soaking up the tasty broth.
Local Twists
Try the different ways Polish regions make this classic soup. Some mountain communities throw in white beans for extra fullness. Other areas mix in carrots and parsnips for a touch of sweetness. Around Silesia, you might find juniper berries added for an extra flavor kick. Many families like to mix in fresh dill just before eating to brighten everything up.
Keeping It Fresh
This soup actually tastes better after sitting for a day or two as the flavors blend more deeply. Keep it in a sealed container in your fridge for up to five days. When you warm it back up, do it slowly on low heat so the meat doesn't get tough. The sauerkraut will keep softening and blending its flavor into the broth.

Kwaśnica stands for everything good about Polish mountain food - filling, straightforward, and totally satisfying. Over many years of cooking this soup, I've found that taking your time lets all the ingredients reach their full potential. The way the sour sauerkraut softens and blends with the smoky meat creates a truly comforting meal. Whether you're having it on a cold winter day or as part of a Polish celebration, this soup connects you to centuries of cooking tradition while giving you exactly what your body and soul need.
