when re heating do you

last night I cooked a chicken meal with chicken with a milky sauce covered in mash potato, like cottage pie but with chicken, i thought I would reheat it the same tempreture I cooked it at 350 and cover with tin foil do you think this is the best way?

I would simply heat it in the microwave until hot. No need to overcook it and dry it out.

But then again, I'm not a cook.
