Preheat Waring Pro™ Roaster Oven to 450°F (230°C) with roasting rack in place.

Place both chickens, rinsed and dried, on a work surface. Salt and pepper the chickens well, including the cavities. Squeeze a lemon all over outside and inside each chicken. Stuff each chicken with the lemon halves, rosemary sprigs and garlic cloves. Finally, rub olive oil all over the skin.

When indicator light goes off, carefully place chickens on rack in the roasting pan. Immediately reduce temperature to 400°F (200°C). For browner skin, baste chickens every 15 minutes while roasting. Roast for approximately 1 hour and 10 minutes,* until the juices run clear when a thigh is pierced.

*If roasting one chicken, reduce roasting time by 20 minutes.
