Spatchcocked turkey is a turkey that is no longer in its whole shape. In a previous recipe post, I smoked whole turkey with the pellet grill, for you to compare. Instead, the spatchcocked turkey has its back bone removed and is flattened out. Therefore, it cooks in a flat layer directly on the grill grates. This means there is no hollow center cavity in the turkey when you cook it, which allows for more room for the hot heat of the smoker to flow around the spatchcocked turkey in the Traeger.
