• 1 tbsp vegetable oil or lard (for sautéing)

For Garnish:

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.

• Great with roasted meats, dumplings, or pierogi for a full Polish spread.
