Preparation -- 15 minutes

Pre-heat the oven to 180 degrees celsius or 350 degrees fahrenheit. Peel the onion and garlic clove, finely chop the garlic and divide the onion into half thin rings.

Heat a knob of butter in a skillet and sauté the onion and garlic for a few minutes. Meanwhile coat an oven dish with butter. Peel the potatoes and divide them into thin slices.

The easiest way is using a food processor or mandoline. Combine the potato slices with the onion and garlic and divide them evenly over the oven dish.

Combine the eggs and cream in a bowl and season with nutmeg, pepper and salt. Divide the mixture over the oven dish and make sure the potatoes are covered as much as possible.

Finish with a layer of grated cheese.
