Question: how long does it take to bake chicken breast at 425?
Answer: At 425 F degrees (220C) chicken breasts will bake in about 20 to 25 minutes. Of course it depends on the thickness of your breasts, so thicker breast will take a bit longer and thinner breasts will take a bit less time. That's why the best way to tell when your chicken is done is to use a meat thermometer.
