The temperature that chicken should be baked in the oven at is 350 F.
Preheat the oven and for the best results have the chickened thawed out first so it takes less time for the chicken to bake.
You can thaw the chicken out in the refrigerator overnight before putting it in the oven.
But if you do bake the frozen chicken it will take longer to bake.
If the chicken is thawed out it should take around 45 to 50 minutes for the chicken to bake and be fully done.
Once you see no blood in the chicken it should be fully cooked and ready to eat.
A meat thermometer can also tell you when your chicken is fully cooked and when the meat thermometer reads 165 F then the chicken is done.
