This recipe is naturally very close to gluten-free, but it is still important to check the labels on your ingredients, especially the chicken broth. Some packaged broths can contain additives or flavorings with gluten, so choose a certified gluten-free broth to be safe. The adzuki beans, bay leaves, and salt are typically gluten-free, but if you are cooking for someone with celiac disease or strong gluten sensitivity, make sure all ingredients are processed in gluten-free facilities and that your Instant Pot, utensils, and storage containers are free from cross-contact.
