When cooking with charcoal, the best way to determine how long to smoke chicken breast is to brine the chicken breast overnight. This can be done in several ways, depending on your smoker and your wood. Once brined, your chicken breast is ready for smoking. Place the chicken breast on the smoker and heat the unit to 225°F.
While cooking, the internal temperature of the chicken breast should be at least 150°F, so the longer the chicken is smoked, the better. To smoke chicken breast, start by bringing it.
