Mix together the 1/2 cup of Italian dressing, barbecue sauce and brown sugar.
1/2 cup Zesty Italian Dressing, 1/4 cup Brown Sugar, 1 cup Barbecue Sauce
Put your chicken pieces into a 1 gallon zip top bag.
Pour the marinade over the chicken. Marinate 3 hours or up to overnight.
Preheat your gas or charcoal grill. On a gas grill preheat to low. You want your grill no more than 350 degrees. For a charcoal grill, set up a side for indirect heat so build your hot coals all to one side. Cook chicken over low/indirect heat for 1 hour or until an internal thermometer reaches 165 degrees. Make sure it's skin side up so that the fat from the skin can baste the meat.
Keep an eye on your chicken as all grills can vary. If it's getting to dark before the inside is done reduce your heat further or move it up to a top rack (if using gas). Gas will be easier to control here so I honestly recommend that. Charcoal works, but you'll have less control.
When your chicken has reached 165, turn up the heat and sear the skin side if it's not quite brown enough for you . This is preference. We like really crisp skin. Baste it with some extra barbecue sauce and that's it!
If you use charcoal just move the chicken to the hot side before you baste and remove it.
It's important to know your grill here. Mine cooks hot even at low so I had to move my chicken up to my top rack and away from direct heat to finish up. I did not have to let it sear too long. Maybe 30 seconds.
The marinade should give you great flavor all the way through the chicken and the final baste gives that sweet and sticky outside. Enjoy!
