For mine you will need:
*medium sliced potatos (partially cooked)
*onion
*bacon
*cream
*cheese

Cook onion and bacon together and add a bit of garlic to taste if you wish.
then make the layers - potato, sprinkle of onion/bacon mix, 3 teaspoons of cream dribbled over the top, sprinkle of cheese. Then repeat the layers!
Cook at 160/180 for about 30min! It is AMAZING!!
