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. :-)
Once your chicken is coated, sprinkle your chicken on all parts, sides, etc. with the dry rub. Make sure to massage it all over the chicken and into it's nooks and crannies. You want to coat this as much as you can.
In your Instant Omni Plus 11 in 1, line the entire bottom with aluminum foil. Make sure to cover the bottom heating elements and press the foil to the bottom of the middle part of the oven. This is where you will place your leg quarters on each side.
Once coated, it's time to go into the oven or into the grill. Take your dry rubbed, rotisserie spitted chicken and place it into the air fryer/rotisserie oven or take to your outside grill. We want to cook this chicken on the rotisserie for 1 hour at 400F degrees.
Take your leg quarters (if you had to detach them) and make sure that you butter and dry rub those as well. Place them on each side of the bottom of the oven. You want to make sure that your chicken will have room to rotate.
Set your oven to "Roast" then make sure it's on "Rotate" and not "Convect." Your chicken should start turning slowly. It will do this for one hour. Your kitchen will start to smell heavenly in just about 10 minutes.
After your chicken is done, take it out of the oven (or off the grill) and let it rest for 15 minutes. Go ahead and carve the chicken and put on a platter. You are ready to eat!! :-)
