Heat a baking tray in the oven before you put your pie on it, pop the pie into the oven with a double layer of foil, or preferably non-stick baking paper, on the top - cook it at 180oC (170oC if it's a fan oven) for about fifteen minutes then take off the paper and continue to cook for another 10/15 minutes.
That's my best offering - let us know how you get on.
