Frequently Asked Questions
Can I use jarred or canned sauerkraut instead of fresh refrigerated?
Yes, you can. Canned sauerkraut is softer and has a more muted flavor, but it will still work. If using canned, you may want to add a splash of white vinegar or additional sauerkraut juice at the end to brighten the tang. The refrigerated fresh kind is superior in both texture and flavor, but the soup will still be tasty with canned. If the canned sauerkraut is very soft, add it later in the cooking process so it doesn’t disintegrate completely.
What can I use if I don’t have marjoram?
Marjoram is the traditional herb for kapuśniak, and its sweet, woodsy flavor is hard to replicate exactly. The closest substitute is a combination of thyme and a tiny pinch of oregano (use about 2 parts thyme to 1 part oregano). You can also use a smaller amount of dried sage, which has a similar earthy quality. However, if you can find marjoram, it’s worth seeking out for an authentic taste. It’s usually available in the spice aisle of most grocery stores.
Can I make this soup without meat?
Yes, a vegetarian version is delicious. Omit the pork and kielbasa, and use vegetable broth. To add a smoky flavor, use smoked paprika or a little liquid smoke. Mushrooms—especially dried porcini or fresh cremini—can add a meaty, umami depth. A can of white beans or chickpeas adds protein and heartiness. The soup will still be tangy and satisfying, just in a lighter way. The sauerkraut and vegetables are the stars.
Is this soup healthy?
Kapuśniak is a very nutritious soup. Sauerkraut is a fermented food, rich in probiotics (though some are destroyed by heat) and fiber, and it’s packed with vitamin C. The soup is loaded with vegetables and lean protein (especially if you use pork shoulder or chicken). It’s relatively low in fat if you trim the meat and moderate the sausage. The broth is hydrating and mineral-rich from the bones and vegetables. It’s a balanced, whole-food meal that’s been nourishing families for generations. The sour cream adds some fat, but you can omit it or use a lighter version if you prefer.
Can I add other vegetables?
Absolutely. Kapuśniak is a flexible soup. Diced turnips, parsnips, or rutabaga are traditional additions in some regions. Chopped kale or spinach can be stirred in at the end for extra greens. Some cooks add a chopped tomato or a spoonful of tomato paste for a slightly different color and flavor. The basic formula of sauerkraut + meat + root vegetables is the foundation, and you can adapt it to what’s in your fridge. Just be mindful of cooking times for different vegetables, and add quicker-cooking ones later in the process.

Prep Time:
20 minutes
Cook Time:
1 hour 30 minutes
Total Time:
1 hour 50 minutes
Servings:
6–8 bowls
Ingredients
- 1 lb bone-in country-style pork ribs or boneless pork shoulder, cut into chunks
- Salt and freshly ground black pepper
- 1 tablespoon vegetable oil (if needed)
- 1 large onion, chopped
- 2 medium carrots, sliced
- 2 celery stalks, sliced
- 3 garlic cloves, minced
- 2 cups good-quality sauerkraut, drained (reserve juice if desired), roughly chopped
- 6 cups chicken or vegetable broth (or water)
- 2 bay leaves
- 3–4 whole allspice berries (or ¼ teaspoon ground allspice)
- 1 tablespoon dried marjoram, divided
- 8 oz smoked Polish kielbasa, sliced into rounds or half-moons
- 2–3 medium waxy potatoes (Yukon Gold or red), peeled and diced
- Sour cream, for serving
- Fresh chopped dill, for serving
- Rye bread, for serving (optional)
Instructions
- Season and sear the pork: Pat the pork dry and season with salt and pepper. In a large Dutch oven or soup pot, heat the oil over medium-high heat. Sear the pork on all sides until deeply browned. Transfer to a plate.
- Sauté the aromatics: In the same pot, add the onion and cook until softened, about 5 minutes, scraping up any browned bits. Add the carrots and celery; cook for 3–4 minutes. Stir in the garlic and cook for 30 seconds.
- Add the sauerkraut and broth: Add the drained sauerkraut (rinsed if you prefer a milder tang) and cook for 2–3 minutes. Return the pork to the pot. Pour in the broth, and add the bay leaves, allspice, and half of the marjoram. Bring to a boil, then reduce heat to low. Cover partially and simmer for 1 hour, or until the pork is tender. If using pork ribs, remove them, shred the meat, and return it to the pot, discarding the bones.
- Add potatoes and kielbasa: Add the diced potatoes, sliced kielbasa, and remaining marjoram. Continue to simmer, covered, for 20–25 minutes, until the potatoes are fork-tender.
- Season and serve: Discard the bay leaves and allspice berries. Taste the soup and adjust seasoning with salt, pepper, and a splash of reserved sauerkraut juice if you like it tangier. Ladle into bowls, top with a dollop of sour cream and a generous sprinkle of fresh dill. Serve with dark rye bread.
Notes
- For the best flavor, use fresh refrigerated sauerkraut, not canned. Rinse it for a milder soup, or leave it as is for a robust tang. A splash of reserved sauerkraut juice at the end can brighten the flavor.
- You can substitute the pork ribs with smoked ham hock, bacon, or a combination of meats. Smoked meats add incredible depth.
- Leftovers keep in the fridge for up to 5 days and freeze well (though potatoes may soften upon thawing). For best freezing results, cook potatoes separately and add when reheating.
- The soup is naturally gluten-free if you use gluten-free broth and omit the rye bread on the side. Always check labels on processed kielbasa for hidden gluten.
