Many people like cooking their turkey in a convection oven because convection ovens usually result in even cooking and browning and shorter cooking times. Convection ovens circulate and speed the hot air using fans, so food is browned by the surging, circulating hot air. In general, the cooking time for a turkey cooked in a convection oven is reduced by 25 percent compared with a conventional oven.
Preheat the oven to 300 degrees. Follow the cooking times below for a roasted turkey in a convection oven.
6 to 10 lbs.: 1 1/4 to 1 3/4 hours. 10 to 14 lbs.: 1 3/4 to 2 1/4 hours. 14 to 18 lbs.: 2 1/4 to 2 1/2 hours. 18 to 22 lbs.: 2 1/2 to three hours. 22 to 24 lbs.: 3 to 3 3/4 hours.
Follow the below cooking times for a stuffed turkey. The stuffing must reach an internal temperature of 165 degrees before you remove the bird from the oven.
6 to 10 lbs.: two to 2 1/4 hours. 10 to 14 lbs.: 2 1/4 to 2 1/2 hours. 14 to 18 lbs.: 2 1/2 to three hours. 18 to 22 lbs.: three to 3 1/2 hours. 22 to 24 lbs.: 3 1/2 to 3 3/4 hours.
When convection roasting a turkey, make sure you place the turkey on a poultry rack in a shallow pan. The hot air will be able to circulate under and all over the bird for even cooking and browning. Rub the turkey with butter before roasting and tent the turkey with foil if the bird's skin becomes too brown. Use an oven-friendly meat thermometer stuck in the thickest part of the turkey's thigh to ensure the turkey is cooked. Make sure the internal temperature reaches 165 degrees.
