The time required to boil chicken tenders will depend on how thick the tenders are and how many you are cooking. Generally, for smaller chicken tenders that are about 1/4 inch thick, you should boil them for about 4-5 minutes until they are cooked through. If you are boiling larger chicken tenders that are about 1/2 inch thick, you should boil them for about 7-8 minutes. It is important to make sure that the chicken tenders reach an internal temperature of 165°F before consuming them.
