  • 25 grams dried porcini mushrooms
  • 400 ml cold water
  • 250 grams chestnut mushrooms washed & sliced
  • 1 large onion sliced
  • 2 teaspoon olive oil
  • 2 tablespoon red wine vinegar
  • 800 ml vegetable stock made with 2 x vegetable stock cubes/stock pots
  • 1 teaspoon marmite
  • 2 whole dried bay leaves
  • 1 teaspoon dried thyme
  • 1 pinch black pepper to taste


  • Place the dried porcini mushrooms into a bowl, pour in the cold water, stir, then set them aside to soak
  • Heat the olive oil in a large pan on medium, then add the onions to cook and soften
  • Once the onions are softened, add the sliced chestnut mushrooms. Cook until the water is released from them and the pan starts to caramelise from the cooked onions and mushrooms
  • Add the red wine vinegar and scrape the pan with a wooden spoon to deglaze the pan and get all the flavour
  • Next pour in the rehydrated porcini mushrooms and water they were soaking in. Stir, then turn up the heat to high to bring the gravy to a boil
  • Pour in the vegetable stock, stir in the marmite, add the thyme and bay leaves, stir and reduce the heat to simmer for 5-10 minutes to intensify the flavour
  • When ready, discard the bay leaves and season with black pepper to taste. The gravy can be served as it is, or strained to remove the onions and mushrooms. For a thicker gravy, blitz some of the onion and mushrooms into the gravy
