How long do you cook a fifteen pound turkey in convection oven?

Cooking time for a 15 pound turkey in a convection oven may vary depending on the specific oven model and settings, but here's a general guideline:

1. Preheat your convection oven to 325 degrees Fahrenheit (165 degrees Celsius).

2. Remove the neck and giblets from the turkey cavity and rinse the inside and outside of the turkey thoroughly. Pat the turkey dry with paper towels.

3. Season the turkey inside and out with salt, pepper, and any desired herbs or spices. You can also add butter, olive oil, or other seasonings under the skin.

4. Place the turkey breast-side up on a roasting rack in a roasting pan.

5. Insert a meat thermometer into the thickest part of the thigh, but not touching the bone.

6. Roast the turkey in the preheated convection oven for approximately 3 hours, or until the internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius) as indicated by the meat thermometer.

7. Baste the turkey every 30 minutes or so with the pan juices to keep it moist.

8. Once the internal temperature of the turkey reaches 165 degrees Fahrenheit, remove it from the oven and let it rest for about 15 minutes before carving and serving.

Please keep in mind that cooking times may vary depending on the wattage and efficiency of your convection oven, so it's always a good idea to check the internal temperature of the turkey with a meat thermometer to ensure that it's fully cooked.
