Place chicken into a large plastic bag. Add taco seasoning and the juice from both limes and the zest from one (you can use the zest both for a stronger lime flavor).
Rub chicken in bag to mix seasoning. Place chicken in the fridge for at least an hour but overnight would be best.
Preheat oven to 375 degrees F. Place chicken in a dish and bake for 30-40 minutes or until chicken is fully cooked. Time will vary depending in the size of your chicken breast. For small chicken breast check the temperature around 20 minutes. Chicken should be over 165 degrees F before eating.
