The length of time it takes to cook a boneless chicken breast depends on the method of preparation, oven temperature and the size of the breast. For instance, a 4-ounce boneless chicken breast baked at 350 degrees Fahrenheit should be cooked for 20 to 30 minutes. The chicken should reach an internal temperature of 165 degrees Fahrenheit.
When grilling or broiling a skinless, boneless chicken breast that weighs a total of 4 to 5 ounces, the meat should be cooked for a total of 12 to 15 minutes. It should be turned once halfway through the cooking time. The meat is done when it is no longer pink inside and reaches an internal temperature of 170 degrees Fahrenheit. Fried chicken breasts that have been dipped in a coating of flour also take approximately 12 to 15 minutes to cook.
To saute skinless, boneless chicken breast halves, cook the meat until it is no longer pink. This should take approximately 8 to 12 minutes. The chicken should reach an internal temperature of 170 degrees Fahrenheit. Chicken can be checked for doneness by piercing the thickest portion of the meat with a fork if a meat thermometer is unavailable. The juices from the chicken should be clear, and the fork should slide easily into the meat.
