What You’ll Need for Polish Sauerkraut Soup

Ingredients

1 lb sauerkraut (rinsed and drained, but not completely)

6 cups chicken or beef broth (homemade or store-bought)

1 medium onion, finely chopped

2 medium carrots, diced

2 potatoes, peeled and cubed

2 cloves garlic, minced

1 lb smoked kielbasa or bacon, sliced

1 bay leaf

1 tsp caraway seeds (optional, but traditional)

1 tsp black pepper

1 tbsp vegetable oil or butter

Salt, to taste

Fresh dill or parsley, for garnish

How to Make Polish Sauerkraut Soup

Step 1: Prepare the Base

In a large soup pot, heat oil or butter over medium heat. Add the onion and garlic, sautéing until fragrant and golden. This forms the base flavor of your soup.

Step 2: Add the Meat

Stir in sliced kielbasa or diced bacon. Allow it to brown slightly, releasing smoky, savory flavors that enrich the broth.

Step 3: Build the Soup

Add the carrots, potatoes, and sauerkraut. Stir well to combine.

Step 4: Pour in the Broth

Add chicken or beef broth along with the bay leaf, caraway seeds, and black pepper. Stir to incorporate, then bring the soup to a gentle boil.

Step 5: Simmer

Lower the heat and let the soup simmer for 45 minutes to 1 hour. The longer it simmers, the deeper the flavors become. Taste and adjust with salt if needed.

Step 6: Serve and Enjoy

Remove the bay leaf. Ladle the soup into bowls, garnish with fresh dill or parsley, and serve hot with rye bread or crusty rolls.

Tips + Tricks for Recipe Success

Don’t Over-Rinse Sauerkraut: A quick rinse removes excess brine but keeps enough tang for authentic flavor.

Use Smoked Meat: Kielbasa or bacon adds richness. If you prefer a lighter soup, substitute with chicken.

Thicken if Desired: For a thicker consistency, mash some of the potatoes in the soup.

Flavor Boosters: A splash of apple cider vinegar or a spoonful of tomato paste can add depth.
