Preheat oven to 350, wash and empty the chicken of the giblets, liver all that stuff. Rub salt and pepper all over the chicken including the empty cavity.
Using a zester or Microplane Fine Grater shred the garlic into a medium bowl, stop when it gets to the point you might hurt yourself and set the rest of the garlic clove aside (keep it for later) and move on to the next. Then zest lemon into same bowl. Then squeeze lemon of all its juices into the bowl, add oil, salt and pepper. Mix together.
Take the lemon husks that you have zested and drained of juice and place inside the open cavity, then add the rest of the garlic and the rosemary. Cover with the marinade and place in oven for 2 hours, baste after 1 hour and once again 30 minutes later.
Remove from oven and let sit for 15 minutes before you cut into the chicken. See the video above for directions on how to carve Rosemary Garlic Chicken.
