This creamy chicken and sauerkraut soup is a modern twist on the classic Amish chicken and sauerkraut soup, which is beloved for its simple, hearty ingredients and comforting tang. Like the traditional version, it’s full of tender chicken, savory vegetables, and of course, that signature sauerkraut flavor, but with a creamy, cozy finish that makes it extra indulgent.

How to Make Slow Cooker Creamy Chicken & Sauerkraut Soup

So easy! Dump it all in the crock pot and come back hours later for dinner!

Add the cooked chicken, potatoes, celery, carrots, onion, Frank’s Kraut, and bay leaves to your slow cooker. Pour in the chicken stock, reserving 1 cup for the roux.

Stir everything together and cover.

Cook on LOW for 6–7 hours or HIGH for about 4 hours, until the vegetables are tender and the flavors have melded.

Remove and discard the bay leaves.

In a small saucepan, melt the butter. Whisk in the flour to form a smooth roux. Slowly whisk in the reserved 1 cup of chicken stock and cook until thickened.

Stir the roux into the slow cooker along with the sour cream. Mix until creamy and well combined. Taste and season with additional salt and pepper as needed.

Serve warm. Top with crumbled bacon and sliced green onions, if you’d like.

Stovetop Directions

If you’d rather make this on the stovetop, you can! Add the chicken, vegetables, Frank’s Kraut, bay leaves, and chicken stock (reserve 1 cup) to a large Dutch oven or soup pot. Bring to a gentle boil, then reduce the heat and let it simmer for about 35-45 minutes, or until the vegetables are tender.

Make the roux in a separate saucepan, whisk it into the pot along with the sour cream, and stir until the soup is creamy and smooth. Season to taste and serve.

How to Store

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave, adding a splash of broth if it thickens. I don’t recommend freezing this soup.

Tips & Substitutions

• Chicken: Rotisserie chicken works perfectly and adds great flavor.
• Vegetables: Feel free to add mushrooms, parsnips, or even a handful of frozen peas at the end.
• Broth: Use low-sodium chicken broth if you need to control your sodium.
• Make it lighter: Swap Greek yogurt for some or all of the sour cream.
• Add smoky depth: The optional bacon takes this soup to the next level.
• Caraway Seeds: Sprinkle some caraway seeds on top for a nutty flavor. 

Health Benefits of Sauerkraut

Sauerkraut brings more to the table than big flavor. Because it’s naturally fermented, it’s full of probiotics that help keep your gut healthy and your digestion on track. It also delivers important nutrients like vitamins C and K, along with minerals such as iron and potassium. When you simmer sauerkraut with tender chicken, the result is a cozy, nourishing soup that delivers protein, probiotics, and plenty of feel-good nutrients in every bowl.
