Clean the mushrooms and cut them into slices. Cut the onion and garlic into small cubes.
Melt the butter in a high pan and sauté the onion with the garlic. Add the mushrooms, sauté briefly, add the vegetable stock and the cream. Bring to a boil, then season with sherry, porcini mushroom powder, salt and pepper. Sprinkle the finished ragout with the parsley and the chives.
Bread dumplings or pretzel dumplings go well with this, but also pasta or rice.
