Step #1: Use your favorite rub on your boneless skinless chicken breasts and place them in the refrigerator for about 4 hours.
Step #2: If using charcoal, place the charcoal on one half of the grill and get it ready. If using a gas grill, only light half the grill and set it to a high setting. To ensure that your chicken breasts stay juicy we will be cooking them first using indirect heat.
Step #3: Place the uncooked, dry-rub covered chicken breasts on the part of the grill that does not have charcoal or flames. Close the grill and let the chicken breasts cook until they have reached an internal temperature of about 150-155 degrees. Chicken should be cooked (prepared) to a temperature of 165 degrees to make it safe for consumption. Even though we are only cooking until we get to 150-155, we will increase the internal temperature in the next few steps.
Step #4: Once the chicken has reached an internal temperature of 150-155 degrees, you will now almost ready to move the chicken over the charcoal or gas burner. Since we have taken the time to cook the chicken in indirect heat, the charcoal should be a loaw to medium temperature and if using gas, you should reduce the temperature to low to medium so you don’t burn the chicken too quickly.
Step #5: If you like BBQ sauce cooked on your chicken, now is the time to coat the chicken in BBQ sauce. The sugars in the BBQ sauce will caramelize and not only give the chicken a nice sweet flavor, but it will help to add to the crispness of the outside of the chicken.
Step #6: Move the chicken over the charcoal or gas burner and monitor the chicken with the top of the grill raised, moving and turning the chicken as needed. You will now cook the chicken until the internal temperature has reached a safe 165 degrees.
Step #7: Once your chicken is done, remove from the grill. The outside of the boneless, skinless chicken breast should be slightly crunchy and quite possibly have the sear marks from the grill that everyone expects from grill food, but the inside will be juicy and tender and cooked to perfection.
Note: An alternative method is to boil the chicken prior to placing it on the grill. If you are going to boil the chicken breasts, there is no need to rub them down. Boiling the chicken ensures that the chicken is completely cooked, allowing you to finish the cooking on the grill.
