1 Broil 4- to 5-ounce boneless, skinless chicken breasts 12 to 15 minutes, turning over about halfway through the cooking time and brushing with sauce or seasoning if desired. 2  Remove chicken when it reaches 170 degrees F and is no longer pink.
Bake for 20 minutes. Place the chicken breasts into the preheated oven and cook them for 20 to 25 minutes, or until they are fully cooked. The most accurate way to test for doneness is with an instant read meat thermometer. Insert the thermometer into the thickest part of the chicken breast.
