How Long to Cook Chicken Breast at 425 Degrees
You'll want to bake chicken breasts for 15 minutes in a 425-degree oven. Be sure not to leave them in the oven too long: When you're cooking at high heat, it's easier to overcook the meat. Once you pull the chicken out of the oven, let it rest for a few minutes on the counter to finish cooking and allow the juices to redistribute inside the meat.
If you/re looking for extra validation to ensure that your chicken breasts are fully cooked, follow a good baked chicken breast recipe and use a meat thermometer to test the middle of the meat. When the internal temperature reaches 165 degrees Fahrenheit, it's safe to eat.
