Sweet potatoes can be baked in a 400 degree oven for an hour. If you are cooking other items in your oven (such as a roast or chicken) you can bake them at a lower temperature. I. e. , if you are roasting a chicken at 350 degrees, put the potatoes in the oven,too, and let them cook about 1. 5 hours.
