<human>:  How long do I need to cook a whole chicken in the oven?
<bot>: The estimated cooking time for a whole chicken in the oven is around 1 hour and 30 minutes at 350°F (177°C). However, it is recommended to always check the internal temperature of the chicken with a meat thermometer to insure it is cooked through, which should read at least 165°F (74°C).
