Step-by-step recipe

check things off as you go

  1. Preheat the oven

    Turn the oven on to 200 °C. Butter the baking dish with half the butter (10 g).

  2. Peel and slice the potatoes

    Peel the 420 g of potatoes and cut them into thin rounds, about 3 mm.

  3. Cook the potatoes

    Put the rounds in a saucepan of cold salted water, bring it to a boil, then let it simmer for 10 min. Drain them in the colander.

    Tip · Start with cold water and give it 10 min at a simmer: overcooked rounds break apart when you build the gratin.

  4. Sauté the onions

    Thinly slice the 2 onions. Cook them in the skillet with the olive oil and the rest of the butter (10 g) over medium heat for 10 min, until they're nice and soft.

  5. Cook the red lentils

    Put the 130 g of lentils in the emptied saucepan with 3 times their volume of water. Cook over medium heat for 10 min, until the water is absorbed.

    Tip · Stir often with the wooden spoon, red lentils stick to the bottom of the saucepan fast once the water goes down.

  6. Make the creamy lentil mix

    Stir the cooked lentils together with the onions, the 170 g of crème fraîche, the salt and the pepper.

  7. Build the gratin

    Lay half of the potatoes in the dish, cover with the lentil mixture, then finish with the rest of the potatoes. Sprinkle with the 30 g of shredded cheese.

  8. Bake until golden

    Bake at 200 °C for 10 min, until the top is golden.
