Holding a Shepherd's pie until dinner I made a Shepherds pie for dinner, its assembled and ready to bake.  I'd like to hold off for a few hours though, maybe 4-5 hours.  

I have no room in my fridge and I don't want to leave it on the counter, so I think the oven is my only option.  The instructions say to bake it at 450 for 30 minutes.  Should I bake it as instructed, then hold it at 200 until ready to eat?    Are there any other methods to do this?

Thanks
Yes, keeping it in a 200F oven will keep it safely outside the bacterial danger zone, but it may also dry out a bit. Covering with foil or adding a pan of water to the rack below may help that, though that may also make the crust soggy. You'll have to experiment a bit.
