The perfect amount of time to bake a chicken breast at 350 degrees Fahrenheit is 25 to 30 minutes. This amount of time ensures that you have a fully cooked chicken breast that is still juicy when you cut into it. If you’re not sure if your chicken is done when you pull it out, you can stick a meat thermometer into the thickest part of the chicken to check if it has an internal temperature of 165 degrees Fahrenheit.
For the best baked chicken breasts, we actually recommend you set your oven to 400 degrees Fahrenheit and bake for 15 to 18 minutes. You can find that to be the best way to get a perfectly juicy baked chicken breast.
