# Leek, potato and Comté gratin

Tender layers of potato and sweet leeks beneath a deeply golden cheese crust.

- **Prep**: 25 min
- **Cook**: 55 min
- **Rest**: 8 min
- **Difficulty**: Easy
- **Serves**: 6 personnes

## Ingredients
- 900 g Waxy potatoes
- 600 g Leeks
- 180 g Comté cheese
- 40 cl Single cream
- 1 clove Garlic
- 20 g Butter
- 1 pinch Nutmeg

## Steps
1. **Slice thinly** — Wash between the leek leaves and slice them into 5 mm rounds. Peel the potatoes and cut them into 3 mm slices. A mandoline gives especially even potato slices; always use its hand guard. Do not rinse the potato slices because their starch thickens the cream.
2. **Pre-cook separately** — Melt the 20 g of butter in a frying pan over medium heat and cook the leeks for 8 minutes, stirring every 2 minutes, without browning them. At the same time, simmer the potato slices in salted water for 6 minutes, then drain. If the leeks begin to colour before softening, lower the heat and add 1 tablespoon of water. Lift and drain the potato slices gently so they do not break.
3. **Assemble the gratin** — Preheat the oven to 190°C. Rub the dish with the cut garlic clove. Alternate thin layers of potatoes and leeks, scattering 120 g of the grated Comté between them, then pour over the 400 ml of cream mixed with the nutmeg, remaining salt and pepper. Press the layers gently to remove large air pockets. Scatter the remaining 60 g of Comté evenly over the surface.
4. **Bake until golden** — Bake in the centre of the oven at 190°C for 45 minutes. Check after 35 minutes: if the cheese is already amber, cover loosely with foil for the final 10 minutes; otherwise leave it uncovered. Insert the knife into the very centre, where the potato layers take longest to cook. Rest the gratin for 8 minutes before serving.
