Enjoy the delicate and aromatic flavors of this mushroom and leek soup. Start by sautéing a mix of mushrooms, such as cremini, shiitake, and oyster, along with leeks and garlic. Add vegetable broth and simmer until the mushrooms are tender. Then, blend the soup until smooth and return it to the pot. Season with salt, pepper, and a touch of thyme for extra flavor. Serve this elegant and comforting soup with a drizzle of olive oil and a sprinkle of fresh parsley.
