Cooking a turkey is a crucial part of many holiday celebrations. Knowing how long to cook a turkey is essential to ensure it is cooked safely and evenly. For a 13-pound turkey, the recommended cooking time is approximately 3 to 3 1/2 hours at 325F (163C) in a preheated oven.
The cooking time may vary slightly depending on the specific type of oven used and the accuracy of the oven’s temperature gauge. It is always advisable to use a meat thermometer to ensure the turkey has reached an internal temperature of 165F (74C) in the thickest part of the thigh, without touching the bone.
