  • 200 gr. polenta
  • 40 gr. butter
  • 40 gr. grated Parmesan cheese
  • 4 king oyster mushrooms
  • A bunch of cavolo nero
  • Handful of hazelnuts (without skin)

  • 3 shallots
  • 1 large garlic clove
  • 400 ml. red wine
  • 200 ml. vegetable stock
  • Dash of balsamic vinegar
  • 1 bay leaf
  • A few sprigs of thyme
  • 100 gr. butter


  1. Preheat the oven to 180 degrees.
  2. Start by making the red wine sauce. Finely chop the shallots and garlic and fry for a few minutes in a sauce pan in a knob of butter.
  3. Add the red wine, vegetable stock, balsamic vinegar, bay leaf and thyme and let it simmer for 15-20 minutes. Sieve the sauce and add back to the pan. Finish the sauce later in step 7. 4. Meanwhile, roast the hazelnuts in the oven for a few minutes, chop them coarsely and set aside.
  4. Heat a griddle pan. Cut the king oyster mushrooms vertically through the middle and grease with a drizzle of olive oil. Cook for 15-20 minutes on the grill over medium heat until tender and golden brown, turning every 5 minutes. If necessary, put something heavy like a pan on top of the oyster mushrooms so that they cook evenly. Then season with salt and pepper.
  5. In the meantime, grease the cavolo nero with a drop of olive oil and a pinch of salt. Bake in the oven for 5-10 minutes until they are crispy.
  6. Put the red wine sauce back on a very low heat and, using a whisk, beat in the cubes of cold butter one by one until it has dissolved. Season with salt and pepper if necessary and keep warm on a very low heat until serving, it must not boil.
  7. Bring 800 ml of water to the boil with a pinch of salt. Add the polenta while stirring with a whisk. Let it boil for about 3 minutes while stirring, add more water if the puree becomes too thick. Turn off the heat and stir in the butter and grated Parmesan and season with a pinch of extra salt if necessary.
  8. Divide the polenta puree over the plates. Place the king oyster mushroom steaks and the cavolo nero on top and finish off with some toasted hazelnuts. Serve the red wine sauce on the side.
