In a small mixing bowl, put your garlic powder, onion powder, salt, pepper, ground coriander, chili powder, paprika and mix together.
In a small sauce pan or in the microwave, melt your butter
Once melted, take your marinate brush and brush the chicken all over with the butter. (NOTE) you can also use olive oil if you feel it's a safe fat for your diet. :-)
Sprinkle your dry rub all over the chicken, making sure to get into all the nooks and crannies for flavor!
Preheat your oven to 325F.
Once your chicken is dry rubbed, line your roasting pan with aluminum foil, and place your chicken breast side down. This will allow the juices to to cook through the chicken from top to bottom, keeping the chicken breast more moist.
Take your dry rubbed chicken and place it into the oven at 325F for two hours. After the first hour, pull the chicken out and make sure it's not cooking too fast on the outside. If it is, cover the chicken loosely on top with a piece of tin foil.
About 15 minutes prior to it being ready, flip your chicken over and let the breast side brown in the oven.
After your chicken is done, take it out of the oven and let it rest for 15 minutes. Go ahead and carve the chicken and put on a platter. You are ready to eat!! :-)
