Ingredients

  • 50 g shiitake mushrooms
  • 50 g oyster mushrooms
  • 50 g brown button mushrooms
  • 2 shallots
  • 0.5 lemon
  • 20 g butter
  • Salt
  • Pepper
  • 1 egg yolk
  • 75 g finely ground lean beef
  • 2 tbsp heavy cream
  • 3 sprigs tarragon
  • 800 g large skin‑on chicken breast fillets (4 fillets)
  • 150 g starchy potatoes
  • 500 g Jerusalem artichokes
  • 275 ml milk (1.5% fat)
  • 1 tbsp Rapeseed Oil
  • 50 ml dry vermouth (or apple juice)
  • 75 ml white wine (or grape juice)
  • 125 ml poultry stock
  • 125 ml Soy cream
  • nutmeg

Instructions

  1. 1.

    Clean and finely dice the mushrooms. Peel and finely chop the shallots. Squeeze out the lemon juice.

  2. 2.

    Heat butter in a pan. Sauté the mushrooms and shallots over medium heat, stirring until liquid evaporates. Season with salt, pepper, and a splash of lemon juice; let cool completely.

  3. 3.

    Separate the egg white from the yolk. Mix ground beef with the yolk, heavy cream, salt, and pepper; refrigerate (reserve the egg white for another use).

  4. 4.

    Wash, dry, and finely chop tarragon leaves. Set aside half; mix the other half with the mushroom mixture and meat.

  5. 5.

    Pat chicken fillets dry and make a shallow horizontal cut on the rounded top of each breast.

  6. 6.

    Insert a wooden spoon handle into the slit and move it back and forth to create a pocket.

  7. 7.

    Fill a pastry bag fitted with a long nozzle with the mushroom filling and pipe it into the chicken breasts. Seal openings with toothpicks, cover with cling film, and refrigerate until ready to cook.

  8. 8.

    Wash, peel, and quarter potatoes; wash Jerusalem artichokes, scrub thoroughly, and cut into pieces. Boil both in milk with a pinch of salt for 20 minutes covered over low‑to‑medium heat.

  9. 9.

    Heat oil in a non‑stick pan. Season chicken with salt and pepper; sear each side until golden. Transfer to a baking sheet and roast at 200 °C (180 °C fan) for 12–15 minutes, cover with foil, then let rest in the turned‑off oven for 10 minutes.

  10. 10.

    Stir vermouth and white wine into the pan. Add poultry stock and soy cream; reduce over medium heat until creamy.

  11. 11.

    Drain Jerusalem artichokes and potatoes, reserving the milk. Mash the vegetables and whisk in enough milk to create a smooth puree. Season with salt, pepper, and grated nutmeg.

  12. 12.

    Add remaining tarragon to the sauce. Use an immersion blender to lightly froth the sauce. Slice chicken into rounds, plate with puree and sauce.
