Preheat an oven to 375 degrees. Cover a baking pan with foil. Place breaded or plain frozen chicken tenders on foil. Bake chicken tenders for 20 to 30 minutes, or until the juices run clear. Pierce the thickest portion of the tenders with a fork to make sure the juices run clear, or test the chicken with a meat thermometer, which should read 170 degrees. Bake thawed uncooked chicken tenders for 15 to 25 minutes, or until the juices run clear and/or a meat temperature reads 170 degrees.
