This soup is made with a variety of mushrooms, such as cremini, shiitake, and oyster mushrooms, which are sautéed with leeks, onions, and garlic until they are golden brown and fragrant. The mushrooms and leeks are then simmered in a vegetable or chicken broth along with herbs and spices to enhance the flavors. The soup is often finished off with a drizzle of cream or a dollop of crème fraîche and can be garnished with fresh chives or parsley. Mushroom and leek soup is a comforting and flavorful dish that is perfect for any occasion.
