Yes, you can definitely use a slow cooker or Instant Pot to make the chicken and dumpling soup. For the slow cooker, simply combine all the ingredients, including the shredded chicken and dumplings, in the slow cooker and cook on low heat for 6-8 hours or on high heat for 3-4 hours. If using an Instant Pot, set it to the "Soup" mode and adjust the cooking time to around 20 minutes. Both methods will result in a flavorful and comforting chicken and dumpling soup with minimal effort.
