1 packet of potato and leek soup mix
1/2 cup grated cheese
1/4 cup finely grated parmesan cheese (I just use cheapie packet stuff you get in the pasta sauce aisle)
Approximately 5 or 6 potatoes. This all depends on size and how many people you are serving. I usually use 3 medium sized potatoes for the two of us.
3/4 cup milk
Preheat your oven from anywhere between hot to moderate. It really depends on your oven. You're aiming for a good temperature to cook the potatoes through and then brown the cheese, without burning the top.
Combine the milk and packet soup mix in a jug and set aside.
Peel and thinly slice the potatoes.
Layer about half the potatoes on your baking dish and pour over half the milk and soup mix.
Top with half of both cheeses.
Repeat the potato, milk and cheese process.
Cover the baking dish loosely with alfoil and bake for about half an hour or until the potatoes are soft.
Remove the alfoil and put the potato bake in the oven until golden brown.
Allow a few minutes to cool before serving if you've got time - this gives the juices to cool and settle a bit, making it easier to dish out.
