Ingredients (for 6 persons):
750 g potatoes
½ l milk
1 egg
50g butter
125g grated cheese
garlic
Grated nutmeg
salt and pepper
Preparation:
Peel and slice the potatoes.
Mix the milk, the egg, garlic, nutmeg salt and pepper in a bowl.
Place the potatoes in a large saucepan and cover with the milk mixture. Bring to a boil over medium-high heat, stirring occasionally so that the potatoes do not stick to the bottom of the pan. Reduce the heat to medium and cook, stirring from time to time, until the potatoes are tender but not falling apart, about 10 minutes.
Using a slotted spoon, transfer the potatoes to a large gratin dish if your pan cannot go into the oven. Sprinkle grated cheese and put the butter cut in small pieces on the top of the gratin.
Bake, uncovered, until the gratin is crisp and golden on top, about 20 to 30 minutes at 200°C.
Serve immediately.
