  • 1 bay leaf
  • Thyme sprigs, plus a few additional thyme leaves for garnish
  • 50g butter
  • 300g mixed wild mushrooms, cleaned and roughly chopped if large
  • 50 g Comté or Gruyère cheese
  • 200 g soft butter
  • Zest and squeeze 1 lemon
  • Bunch of flat-leaf parsley, leaves very coarsely chopped
  • large pinch of paprika
  • 4 large chicken breasts, preferably Supremes with the wing bone still attached
  • 1 large shallot, sliced
  • 1 garlic bulb, coarsely chopped
  • 3 sprigs of thyme
  • 200 ml fresh chicken stock
  • 1 tbsp olive oil
  • 24 small leeks, cut to the same size, cooked for 3 minutes and then cooled in ice water

Preparation steps

  1. Peel the potatoes and, using a mandolin (if you have one), cut them into slices no thicker than 50p.
  2. Bring milk, cream, garlic, herbs and some spices to the boil in a large pot, then reduce the heat and simmer for a few minutes.
  3. Add the potatoes to the hot milk mixture and simmer for 10 minutes until just cooked through.
  4. Drain the potatoes in a colander over a bowl to catch the liquid – reserving the milk.
  5. While the potatoes are simmering, heat half the butter in a pan until it foams.
  6. Fry the mushrooms for 2 minutes until wilted, season with salt and pepper and set aside.
  7. Rub two small baking dishes (or one medium-sized one) with the remaining butter, sprinkle the thyme leaves over them and grate some cheese over them.
  8. Half fill the molds with potato slices, moisten them with a little milk and grate the cheese over them.
  9. Fill the bowls with potato slices, add enough milk to cover the mixture, and top with the mushrooms and remaining cheese.
  10. For the chicken, mix about two thirds of the butter with the lemon zest and half of the juice, the parsley, paprika and a little salt and pepper.
  11. Lightly lift the skin off each breast, spread or pipe the flavored butter under the skin, then pull the skin back over. If desired, refrigerate up to a day in advance.
  12. Preheat oven to 220°C/200°C fan/gas 7.
  13. Heat the remaining butter in an ovenproof skillet until foaming.
  14. Fry the chicken in the pan, constantly brushing with the butter, until it begins to brown.
  15. Add shallot, garlic, thyme and stock.
  16. Place the chicken, skin side up, in the pan on the top rack of the oven and the gratins on the bottom rack.
  17. Roast both for 25-30 minutes, then remove the chicken and let it rest for 15 minutes while the gratins continue to cook.
  18. Remove the chicken from the pan.
  19. Place the pan back on the stove, squeeze the remaining lemon juice over it, and bring to a boil.
  20. Strain the sauce through a sieve, pressing down all the soft shallots and garlic firmly.
  21. Heat a drizzle of olive oil in another frying pan and heat the leeks again until they begin to color.
  22. Arrange six leeks in a row in the center of each plate.
  23. Cut the chicken diagonally into five thick slices.
  24. Gently fan each chicken breast over the leeks.
  25. Spread the sauce over the chicken and around the leeks.
  26. Serve with the potato gratin.
