  • Close the lid, cook the turkey for about 2 and 1/2 hours, or 15 minutes per pound. Flip the breast every 45 minutes and also rotate occasionally for even cooking and moisture distribution.

This recipe also works for a single boneless turkey breast, but your cooking time will be less, maybe closer to 1 and 1/2 hours. 
Always cook until the internal temperature has reached 165°F.
