Baking Your Chicken. 1  1. Cook your chicken breasts at 400 degrees Fahrenheit (205 degrees Celsius). Make sure your oven is completely preheated before putting the chicken in the oven. 2  2. Check the chicken's temperature regularly. Usually, it takes around 30 to 40 minutes to bake chicken breast. You should start using a meat thermometer to check the temperature about 20 minutes in.
