If you're cooking chicken fries at home, the cook time will depend on how hot your oven is. Most home ovens are between 200-250 degrees Fahrenheit. Chicken fries should be cooked until they reach an internal temperature of 165 degrees Fahrenheit. This usually takes between 15-20 minutes in a home oven.
If you're using a deep fryer, the cook time will be shorter since the oil is much hotter than a home oven. Chicken fries should be cooked in hot oil (between 375-400 degrees Fahrenheit) for about 3-5 minutes until they reach an internal temperature of 165 degrees Fahrenheit.
