Ingredients (Serves 6–8):

For the Soup:

  • 1 lb (450g) smoked pork (kielbasa, ribs, or bacon – or use vegan sausage for plant-based version)
  • 1 large onion , chopped (or shallots for milder sweetness)
  • 2 cloves garlic , minced (or ½ tsp garlic powder)
  • 3 large carrots , sliced (or chopped parsnips for extra sweetness)
  • 2 stalks celery , sliced (adds brightness and crunch)
  • 1 medium potato , peeled and diced (or sweet potato for variation)
  • 4 cups sauerkraut , drained and roughly chopped (store-bought or homemade)
  • 6 cups chicken or vegetable broth (or reserved meat-cooking liquid)
  • bay leaves (for herbal depth)
  • 1 tsp caraway seeds (optional – classic Polish flavor)
  • 1 tsp dried marjoram (or thyme for substitution)
  • Salt and black pepper , to taste
  • 1 tbsp vegetable oil or lard (for sautéing)

For Garnish:

  • Fresh parsley , chopped (or dill for extra freshness)
  • Optional: Sour cream, mustard, or crusty bread

Instructions:

Step 1: Simmer the Smoked Meat

Place smoked pork in a large pot and cover with water. Bring to a boil, then reduce to a gentle simmer for 30 minutes to extract smoky flavor into the broth.

Remove meat and let cool slightly. Chop into bite-sized pieces and set aside. Reserve the cooking liquid and add to the broth later.


Step 2: Sauté the Aromatics

In a separate pot over medium heat , warm oil or lard .

Add chopped onion and cook for 5 minutes until translucent and soft.

Stir in minced garlic and cook 1–2 minutes longer until fragrant.


Step 3: Add Vegetables

Toss in carrots, celery, and potatoes , stirring to coat in the aromatics.

Cook for 5 minutes , allowing flavors to develop before adding wet ingredients.


Step 4: Build the Soup Base

Add chopped sauerkraut to the pot.

Pour in broth or reserved meat-cooking liquid , bringing the mixture to a boil.


Step 5: Season & Simmer

Stir in:

  • Bay leaves
  • Caraway seeds (if using)
  • Dried marjoram

Return chopped smoked meat to the pot and season with salt and pepper .

Bring to a simmer, then cover and cook for 45–60 minutes , stirring occasionally, until vegetables are fork-tender and the broth is richly infused.


Step 6: Serve Warm & Hearty

Ladle hot soup into bowls and top with fresh parsley .

Serve with:

  • Rye bread or crusty sourdough
  • A dollop of sour cream
  • Or a side of mustard for dipping

Each bite brings together:

  • Smoky, tender meat pockets
  • Tangy, fermented sauerkraut richness
  • Sweet, earthy root vegetable depth
  • And that classic herb-infused finish

Tips for Success:

  •  Balance the Sourness: If sauerkraut is overly acidic, rinse lightly under cold water before adding.
  •  Lard Hack: For deeper flavor, sauté veggies in smoked pork fat instead of oil.
  •  Add Wine or Vinegar: A splash of white wine or apple cider vinegar brightens the broth.
  •  Thicken the Soup: Stir in a spoonful of sour cream or a bit of flour-water slurry if desired.
  •  Make Ahead Magic: This soup improves in flavor overnight—store in the fridge for up to 4 days.

Serving Suggestions:

  • Perfect with a dollop of crème fraîche or yogurt for creamy contrast.
  • Great with roasted meats, dumplings, or pierogi for a full Polish spread.
  • Ideal with a cold drink like kvass, beer, or lemon water .
