The recommended cooking time for a 5 lb turkey in the oven can vary depending on the specific recipe and cooking temperature. As a general guideline, the standard cooking time for a whole turkey is approximately 15-20 minutes per pound when roasted at 325°F (163°C).
Using this guideline, a 5 lb turkey would take around 1 hour and 15 minutes to 1 hour and 40 minutes to cook at 325°F. However, it's crucial to ensure that the internal temperature of the thickest part of the turkey (typically the breast) reaches a safe minimum internal temperature of 165°F (74°C) to ensure that it is fully cooked and safe to eat.
For the most accurate cooking time, it's best to use a meat thermometer to check the internal temperature of the turkey. Always follow any specific instructions or recipes that you are using, as they may recommend different cooking times or temperatures based on the preparation method. Additionally, make sure to let the turkey rest for a few minutes after taking it out of the oven before carving and serving.
