Step-by-step recipe

check things off as you go

  1. Preheat the oven

    Turn the oven on to 180°C (thermostat 6).

  2. Peel the potatoes

    Peel the potatoes and cut them into thin rounds (2-3 mm).

  3. Cook the potatoes

    Cook the potato rounds for 5 min in the saucepan of salted boiling water. Drain and set aside.

  4. Sear the salmon

    In the hot skillet with a drizzle of olive oil, cook the salmon fillets 2 min per side over medium heat. Season lightly with salt and pepper and set aside.

    Tip · To keep the salmon from falling apart, don't flip it too much in the skillet.

  5. Blanch the spinach

    Drop the spinach into the salted boiling water for 1 min, drain and squeeze out the water. Roughly chop it.

  6. Make the sauce

    In the saucepan, mix the crème fraîche, milk, nutmeg, salt and pepper. Warm it for 2 min over low heat without boiling.

  7. Build the gratin

    In the baking dish, alternate a layer of potatoes, the spinach, the flaked salmon and a little sauce. Repeat and finish with the remaining sauce.

    Tip · For a crispier gratin, slide it under the broiler for 2 min at the end.

  8. Bake the gratin

    Put the dish in the oven for 15 min until the top is golden.
