For a vegan-friendly option, this mushroom soup recipe is perfect. Start by sautéing onions, garlic, and celery in a pot until they are softened. Add sliced mushrooms and cook until they release their moisture. Transfer the mixture to a food processor and blend until smooth. Return the mixture to the pot, add vegetable broth, and simmer until the flavors meld together. To make it extra creamy, you can also add coconut milk or cashew cream. This vegan mushroom soup is hearty, flavorful, and satisfying.
