How long does it take to cook a chicken?

It depends on the temperature, size of the chicken, and how well you want to cook your chicken, but I would suggest putting it in the oven on 350 until the chicken changes color so that it looks cooked, then insert a toothpick or stick inside the meat to see if it is pure white or still red inside. If it is red, then it is not cooked yet and will need a little bit longer. 15 minutes per pound at 350 degrees 15 minutes per pound at 350 degrees
