Most chicken nuggets are made with white meat, which has a lower fat content than dark meat. This means that they will cook faster and at a lower temperature. The general rule is that chicken nuggets should be cooked at 425 degrees Fahrenheit for about 15-20 minutes, or until they are golden brown and cooked through. Some people like to cook their chicken nuggets for a little longer to get them extra crispy, but this is not necessary. As long as the internal temperature of the chicken nugget reaches 165 degrees Fahrenheit, it is safe to eat.
