Grilling can dry out even the best cuts of chicken, but proper seasoning seals in moisture and watching your cook time results in a juicy piece of chicken. In the mid-'80s, Weber produced a new gas grilling method, replacing the lava rocks used in most grills at the time with metal bars. This reduced flame flare-ups and evenly distributed the heat. Even heat distribution lets you grill without over-cooking and drying out your chicken.
Light your Weber gas grill and turn the burners to high. Close the lid on the grill for 10 to 15 minutes, allowing the grill to preheat.
Season your chicken with a rub three to four hours before grilling. This cures the meat and seals in the moisture, keeping your chicken from drying out while it grills. You can use a glaze instead of a rub and apply it as you grill the chicken. The glaze also locks the moisture in the meat.
Turn the Weber's burners down to medium heat. Spray the grates with a light coat of cooking spray.
Place boneless, skinless chicken breast and thighs onto the grill over direct medium heat for four to six minutes. Baste the chicken with a glaze if you choose a glaze over a rub. Turn the breast and thighs over for an additional four to six minutes, then remove them from the grill.
Grill chicken halves over indirect heat for one to 1 1/4 hours. Turn off the center burners on the Weber grill. Place the chicken halves in the center of the grill and cook for 30 to 40 minutes. Turn the halves over and cook for an additional 30 to 40 minutes, removing them from the heat.
Cook chicken pieces on the Weber grill over indirect heat. Breast and wings should grill for 15 to 20 minutes on both sides. Leg and thighs should cook for 20 to 25 minutes on both sides. Use a food thermometer to check your chicken. Poultry should cook to an internal temperature of 165 degrees. When fully cooked, remove the chicken pieces from the grill.
Grill a whole chicken over indirect heat for 30 to 45 minutes on one side. Turn the chicken over and grill for an additional 30 to 45 minutes, removing once the chicken finishes cooking.
