To make this Sausage Cranberry Stuffing Recipe gluten-free, replace the regular bread with certified gluten-free bread cut into cubes and dried before use. Confirm that the Italian sausage, chicken broth, dried cranberries, butter, herbs, apple, onion, celery, garlic, salt, and black pepper are gluten-free and free from cross-contact. Some sausages, broths, and dried fruits may contain gluten-based additives or be processed in shared facilities, so check labels carefully. Use clean cookware, utensils, and a separate baking dish or prep area to prevent cross-contamination.
