How long do you cook a 18.5 pound turkey?

You'll need to cook a 18.5 pound turkey for approximately 4-5 hours at 325°F (165°C).

Here's a more precise breakdown:

* Unstuffed turkey: Allow 13-15 minutes per pound.

* Stuffed turkey: Allow 15-18 minutes per pound.

Important Considerations:

* Always use a meat thermometer to ensure the turkey is cooked through. The internal temperature should reach 165°F (74°C) in the thickest part of the thigh.

* Rest the turkey for at least 20 minutes after cooking before carving to allow the juices to redistribute.

* Adjust cooking time based on your oven and altitude.

Remember, these are just estimates. You should always check the turkey's internal temperature to ensure it's fully cooked.
