Rinse chicken, pat dry and place in roasting pan. Stuff cavity with garlic cloves and lemon halves. Rub fat all over chicken and sprinkle with herbes de Provence, salt and pepper.
Put chicken in oven and reduce heat to 375 degrees. Roast until chicken is 160 degrees, an hour to an hour and a half, depending on size of chicken. Remove from oven and tent with foil to rest for 20 minutes. (Chicken will continue to cook and reach 165 degrees while resting.)
