Equipment

Method
 

  1. Heat the oven to 180 degrees Celsius 356 Fahrenheit; Grease a 10-Inch Tart pan (26cm), bottom and sides.
Chestnut Almond Crust
  1. Mix all the dough ingredients, line a pan, and bake for 20-23 minutes, until it sets and the edges are golden. Let cool on a wire rack.
Mushroom Filling
  1. Chop the king oyster mushrooms into small cubes of about half a cm (0.2 inches); Slice the champignon mushrooms, tear or cut the oyster mushrooms into 2-3 parts - chop the hard part of the mushroom.
  2. Heat the oil in a large pan or wok, add leek, onion, garlic, and thyme, and fry on medium-high heat for about five minutes, until the onion softens. Reduce to medium heat, add mushrooms and shitake powder, and sautรฉ for about ten minutes until the mushrooms shrink and the liquid evaporates.
  3. Spread the filling over the baked dough.
Royal Sauce
  1. Put the dry ingredients in a medium bowl, add olive oil, and gradually add oat milk, constantly whisking until you get a smooth mixture without lumps. Taste and adjust seasoning if necessary. Pour the sauce over the Mushroom mixture, and tilt the pan slightly for even distribution.
  2. Put in the oven and bake for 45-55 minutes until the filling is set and nicely browned. Let cool for about fifteen minutes before serving to allow the quiche to set.

Notes

๐Ÿ’กDried shiitake mushroom powder has a fantastic taste and aroma. One or two tablespoons will do wonders for many dishes. Just grind dried shiitake mushrooms in a strong blender until you get a powder; store in an airtight container.
๐Ÿ’กYou can quickly make vegan yogurt sauce to serve with the quiche: mix a cup of vegan yogurt with lemon juice to taste, and add a drop of apple cider vinegar, olive oil, minced garlic, chopped herbs (chives, mint, or dill), and season with salt and pepper, mix well, if If necessary - dilute with a bit of water and serve.
