Cooking a turkey is a crucial part of many holiday celebrations. Knowing how long to cook a turkey, especially a 15-pound turkey, is essential to ensure a juicy and flavorful meal. The cooking time for a 15-pound turkey will vary depending on the method used, but generally, it will take between 3 and 4 hours to cook in an oven at 325F (165C).
To ensure food safety, it’s important to use a meat thermometer to check the internal temperature of the turkey. The turkey is done cooking when the internal temperature reaches 165F (74C) in the thickest part of the thigh, without touching the bone.
