If you're a fan of wild mushrooms, this soup is a must-try. It combines a variety of wild mushrooms, such as porcini, shiitake, and oyster mushrooms, with onions, garlic, and thyme for a robust and aromatic flavor. The mushrooms are sautéed until golden brown, then simmered in a mixture of vegetable broth and white wine. Finish the soup with a drizzle of truffle oil for an extra touch of luxury.
