How long do you cook a fifteen pound turkey?

Cooking times will vary based on the specific oven and the weight of the turkey.

The general guideline for cooking a whole turkey is 15-20 minutes per pound at 350°F.

For a 15-pound turkey, this would mean cooking it for approximately 3 hours and 45 minutes to 4 hours and 30 minutes.

Always monitor the internal temperature of the turkey to ensure it reaches the safe internal temperature of 165°F before removing it from the oven.

It's also important to check the temperature in different parts of the turkey (breast, thigh, and stuffing if applicable) to ensure even cooking.
