For a vegan variation, substitute the butter with olive oil or coconut oil, the chicken broth with vegetable broth, and the heavy cream with coconut cream or cashew cream. To enhance the depth of flavor, consider adding a pinch of smoked paprika or a dash of nutmeg. If a smoother consistency is desired, use an immersion blender to partially or fully puree the soup after cooking. Soup can be stored in the refrigerator for up to 3 days or frozen for up to 2 months. Reheat gently on the stovetop or in the microwave.
