  1. Preheat the oven

    Wash the zucchini, trim the ends and peel them into thin ribbons with a knife on a cutting board.

    Tip · Serve with a green salad to balance the meal.

  3. Sauté the zucchini

    In a hot skillet with 1 tbsp of olive oil, sauté the zucchini ribbons over medium heat for 5 min, stirring. Season lightly with salt and pepper.

    Tip · To keep the gratin from getting watery, sauté the zucchini well over high heat before mixing.

  4. Drain the tuna

  5. Mix it together

    In a mixing bowl, beat the eggs with the crème fraîche, then add the nutmeg, salt and pepper. Stir in the zucchini and tuna.
