How long to cook a 3.8kg turkey?

It's impossible to give you a precise cooking time without knowing the specifics of your oven and the turkey itself.

Here's why you need more information:

* Oven Temperature: Different ovens cook at different rates.

* Stuffing: A stuffed turkey will take longer to cook than an unstuffed one.

* Turkey Shape: A turkey with a lot of breast meat will take longer to cook than one with more legs and thighs.

* Bone-in vs. Boneless: Bone-in turkeys take longer to cook than boneless ones.

Here's how to calculate cooking time:

1. Use a Meat Thermometer: The safest and most accurate way to determine doneness is with a meat thermometer. The internal temperature should reach 165°F (74°C) in the thickest part of the thigh.

2. Start with a General Guideline: A general guideline is to allow 13-15 minutes per pound for a 3.8kg (8.4lb) turkey at 325°F (165°C). This would be approximately 3 hours and 15 minutes to 3 hours and 45 minutes.

3. Adjust for Your Oven: If your oven tends to run hot or cold, you may need to adjust the cooking time accordingly.

4. Check for Doneness: Begin checking the internal temperature of the turkey after the minimum cooking time.

Remember: It's better to err on the side of caution and cook the turkey a bit longer than to undercook it. Enjoy your delicious turkey!
