Mastering how to reheat fried chicken in the oven is literally one of the best cooking hacks that you can learn. I hate food waste and one of the best ways is to use up leftovers - properly. There's no use cooking soggy fried chicken up, you need to make it crisp and delicious again without drying it out.
Place a wire baking rack on top of a baking sheet. Put the chicken pieces on top, with a couple of inches of space between them.
Cook in the oven for 25- 30 minutes until the chicken thighs are hot and register 150 °F on a thermometer. Turn the oven up to 400°F for 10-15 minutes until the outer skin is nicely crisped again and the thighs are 165°F. Remove and serve!
If you didn't freeze the chicken, you should still reheat it the same way, but for less time at 350°F, and then crisp up at the higher temperature,Calories are not accurate in the nutrition values, it all depends on how much chicken you are re-heating
