1Preheat oven to 450°F. In a small bowl, mix the oil, garlic, grated zest of the lemon and the thyme. Pat the chicken dry, put it (or them) into any sort of dish or roasting pan, and rub all over with the oil mixture. Sprinkle with salt and pepper. Cut the lemon in half and put inside the chicken, or put half inside each.
2Roast for 20 minutes, then reduce the temperature to 375°F and cook for about another hour, or until the juices run clear and the joints wiggle in their sockets.
