Take a big bowl or pot and finely grate the cheese in it, take out 1/3 of the shredded cheese and put aside for topping

Add the cream and thyme to the bowl and mix

Peel the potatoes and use a mandolin or similar to cut thin slices and toss it in the bowl

Mix around so that all slices get coated

Grease a bread tin (works perfect since it takes exactly two rows of slices which is around 1 kg) you might need to adjust your amount of potato to fit the oven container you have

Place the potato slices standing up in the oven dish, this means they need to be tightly packed all the way

Pour the remaining liquid over the potatoes. It should cover all but the top of the slices

Cover with foil and bake in oven at 200°C (400°F) for 30 min

Take off the foil and bake another 20 min

Sprinkle the remaining cheese and then bake yet another 20 min
