After you try this wonderful quiche, you will discover how difficult it is to decide which is tastier – the crust or the filling.
Because the crust, ladies and gentlemen, does not only play the role of a carrier for the filling on top – on the contrary – it takes an equal part in the plot: it’s crunchy and insanely delicious.
The dough is the same crust as the raspberry tart and chocolate chestnut tart with raspberry coating. Still, this recipe is seasoned with shiitake mushroom powder, which adds a deep taste and an intoxicating aroma; When you bake the crust, a wonderful smell spreads in the kitchen, which activates the salivary glands in anticipation.
For the filling, fry onions, leeks, garlic, and thyme, add a selection of mushrooms, season, and sauté until the mushrooms shrink and the liquid evaporates; Transfer to the pan and spread it over the baked dough.
Prepare Royal Sauce from oat milk, add olive oil, nutritional yeast, baking powder, and spices, pour over the mushroom mixture, and bake until set and browned.
Let it cool before serving, sprinkle with chopped chives, and serve with a fresh salad and wine (red or white)
You can accompany the quiche with vegan yogurt dressing, which you can make quickly – and you are set.
