The first step in ensuring juicy turkey breast is to brine it. Submerge the boneless breast or skin-on turkey breasts completely in the brine.
Cover and refrigerate for 8-12 hours. This brining process helps lock in moisture and infuse flavor. Make sure to refrigerate it in an airtight container.
After brining, remove the turkey and pat it dry with paper towels. Preheat your pellet grill, charcoal grill, or electric smoker to 225°F. And place the turkey breast on. For even cooking, make sure the thickest part of the breast faces the hotter side of the smoker. (Optional) Insert a digital thermometer or instant-read thermometer to monitor the internal temperature. If using a gas grill, turn off the burners under the meat and light the burners on the sides.
Once the internal temperature reaches 160°F–162°F (this takes around 2–3 hours depending on the size of the turkey breast), remove and wrap it in aluminum foil. The temp will continue to rise to a safe 165°F during the rest period. Let it rest for at least 15–20 minutes. This allows the juices to redistribute so you don’t end up with dry slices.
