A good temperature to bake your chicken at would be 375 degrees for  30 minutes. You can use a meat thermometer to check the temperature  which should be around 165 degrees. generally bake mine at 350 degrees for 35-40 minutes and then cut at the thickest point to see if the juices run clear. If you bake too long it becomes too dry. I always bake my thawed chicken breasts at 375 degrees for 50 min. and they come out juicy and fully cooked.
