The recommended internal temperature for cooked chicken breast is 165°F (74°C) . This temperature ensures that all harmful bacteria are killed in seconds, making the chicken safe to eat. To check the temperature, insert an instant-read thermometer in the thickest part of the breast. Make sure to avoid touching the bone, as this can give a false reading. If the temperature reads lower than 165°F (74°C), continue cooking until it reaches the recommended temperature. Its important to let the chicken rest for at least 10 minutes after cooking to lock in the juices and flavor.
