Instructions

  1. Slice the potatoes

    Peel the potatoes then slice them thinly (2‑3 mm) using a mandoline or a very sharp knife.

    Time: PT20M

  2. Mix with melted butter

    Melt the butter, pour it over the slices in the bowl, add the salt and gently mix to coat each slice.

    Time: PT5M

  3. Line the pan and compact

    Butter the pan, line it with parchment paper, lay the slices in layers, cover with a second sheet of paper and press firmly with the back of a spoon or a weight.

    Time: PT5M

  4. Slow oven cooking

    Place the pan in the oven at 130°C for 3 hours. The low heat allows the potatoes to confit without browning.

    Time: PT3H

    Temperature: 130°C

  5. Cool, press and refrigerate

    Allow the block to cool, press it again with a weight (e.g., canned goods), then place it in the refrigerator for 12 hours.

    Time: PT0M

  6. Unmold and cut the fries

    Remove the parchment paper, unmold the potato block and cut it into thick fries about 2 cm thick.

    Time: PT5M

  7. Fry the fries

    Heat the neutral oil in a pan over medium‑high heat (≈180°C) and brown the fries on all sides until golden and crispy.

    Time: PT10M

    Temperature: 180°C

  8. Season the salmon

    Sprinkle the salmon steaks with salt and pepper on both sides. Let rest for 2 minutes.

    Time: PT2M

  9. Sear the salmon

    Heat the olive oil in a pan over medium‑high heat, place the steaks skin‑side down, cook 3 minutes, flip and cook 3 minutes on the other side until done to the core.

    Time: PT6M

  10. Prepare the creamy sauce

    In the same pan, sauté the chopped garlic with a drizzle of olive oil, add the halved cherry tomatoes, season with pepper, incorporate the spinach, pour in the liquid cream, let it gently simmer 2‑3 minutes, add the sun‑dried tomatoes, chopped basil, Parmesan and a turn of the pepper mill.

    Time: PT10M

  11. Plating and serving

    Place the salmon steaks on plates, generously drizzle with sauce, serve with confit potato fries and serve immediately.

    Time: PT2M

  • Slow cooking of potatoes at 130°C for 3 hours
  • Pressing and refrigerating the potato block to achieve a compact texture
