Notes

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 soup pot. Bring to a gentle boil, then reduce the heat and let it simmer for about 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.
