How long should I bake a chicken broccoli dish?

If you have a microwave you should defrost the chicken in there. The thing is you want the chicken to get to its proper temp. asap. That' 165F. for 15 seconds, then it's done. If it hovers at a low temp. for too long and doesn't reach 165F. that is promoting bacteria, etc. You should also invest in a digital meat thermometer, about $5.
