Baking the Crust separate from the Pot Pie?
I'm sending a 9x13 pie home with a friend and won't have time to bake, cool and chill. So I can do the filling and chill it (just has gravy poured over cold chicken and veg). Then bake a flat rectangle on a sheet pan, right? What temp and time, 400 till it looks done? Should I pack separately so it doesn't get soggy? Was thinking on a sheet of cardboard or is that too fussy? Just trying to think this through.
