The cooking time for a large turkey can vary depending on several factors, including the size of the turkey, the cooking method, and the oven temperature. As a general guideline, the following approximate cooking times can be used for a fully thawed, unstuffed turkey at a roasting temperature of 325°F (163°C):
- 8 to 12 pounds: 2.75 to 3 hours
- 12 to 14 pounds: 3 to 3.75 hours
- 14 to 18 pounds: 3.75 to 4.25 hours
- 18 to 20 pounds: 4.25 to 4.5 hours
- 20 to 24 pounds: 4.5 to 5 hours
It's important to note that these times are estimates, and it's always recommended to rely on a meat thermometer to ensure the turkey reaches a safe internal temperature. The thickest part of the turkey's thigh should reach 165°F (74°C) to ensure it is fully cooked.
Additionally, if you choose to stuff the turkey, it will require additional cooking time. The stuffing should reach an internal temperature of 165°F (74°C) as well. It's recommended to check the temperature of both the turkey and the stuffing to ensure they are fully cooked.
Remember to allow the turkey to rest for about 20 to 30 minutes after removing it from the oven before carving. This resting period allows the juices to redistribute, resulting in a moister and more flavorful turkey.
Keep in mind that these are general guidelines, and it's important to consult a reliable recipe or cooking guide specific to your turkey size and desired cooking method for more accurate cooking times.
