Question: how long does a 7 pound chicken take to roast?
Answer: Preheat oven to 450 degrees F (230 degrees C) and cook whole (thawed) chicken for 10-15 minutes. Then reduce the temperature to 350 degrees F (175 degrees C) and roast for 20 minutes per pound. (Do not add the extra 15 minutes to the cooking time as with the regular method.)
