Not really, at least not with respect to ingredients. The term u0022stuffingu0022 refers to a mixture of ingredients cooked inside the turkey (or other food) while u0022dressingu0022 is cooked in a baking dish. But the two terms have become interchangeable and many people, myself included, call this savory bread and sausage mixture that we serve at Thanksgiving u0022stuffingu0022 - whether it's cooked inside the bird or out.
