<human>:  How do I roast a chicken?
<bot>: To roast a chicken, preheat your oven to 375 degrees F. Place the chicken, breast side up, in a roasting pan. Rub the chicken with oil and season with salt and pepper. Roast uncovered for 1.5 to 2 hours, or until the temperature of the chicken in its thickest part, such as the thigh, registers 165 degrees F when thermometer is placed into the flesh. Let the chicken rest for at least 10 minutes before serving.
