it open. I never know how long, or what degrees to bake it in and end up having to always cut it into chunks to find out if it is cooked.
Use a meat thermometer to check the internal temperature of the chicken. When fully cooked, chicken should have an internal temperature of at least 165 degrees Fahrenheit.
When using a meat thermometer, stick it into the thickest part of the chicken to get the most accurate reading.
You can use a fork or a knife to poke a small hole into the center of the chicken. Juice will run out of the hole after a few seconds. If the juice is clear and doesn't have a hint of pink than it is done.
Poke a deep hole with a skewer or fork tines. Then wait a few seconds until juice oozes out from the hole. If the chicken is done the juice will be clear. If it shows any pink it needs more cooking. If you are in a hurry, press down on the chicken next to the hole to encourage faster oozing.
Use a thermometer. If you haven't mastered the art of telling if it's done by simply pressing on it, then the only accurate method of knowing is to check the internal temperature.
