how to reheat a frozen cooked chicken
Conventional Oven. Preheat the oven to 350 degrees Fahrenheit and place the oven rack in the middle position. Place the previously cooked, frozen chicken dish on the oven rack. Plan on it taking twice the normal cooking time to reheat a fully frozen chicken dish.If the dish cannot be heated through to at least 165 degrees Fahrenheit in two hours, reduce the size of the chicken dish before initially placing it in the oven. Wrap the chicken tightly in heavy freezer paper for freezing. 2  Don't thaw raw chicken at room temperature or under warm water. 3  Instead, thaw it safely in the refrigerator so it never warms above 40 degrees Fahrenheit. 4  Raw, uncooked frozen chicken should not be cooked in any type of oven directly from its frozen state.
