Preheat oven to 250-300 degrees celcius (or mark 6).

Peel potatoes, wash and drain well.

Slice the potatoes as finely as possible or use a slicer to make things easier.

Rub the garlic around a baking dish or skillet. Grease the dish with butter. I also greased it with cream cheese.

Start laying the sliced potatoes in the dish separating them only slightly, keeping them compact. Add salt, pepper, parsley. Add a layer of cream. Spread the cream on the potatoes. Add some grated cheese.

Repeat step 5 for as many layers as you have potatoes. You might need to add cream or cheese.

On the final layer top with some parsley and a lot of cheese and bake for 45-60minutes.
