This cream of mushroom soup tastes decadent, but it’s secretly healthy. Its creamy texture comes from pureed cauliflower!

The Best Cream of Mushroom Soup Recipe

My cream of mushroom soup recipe is rich, creamy, and deeply savory, but it doesn’t call for you to stir in cream or melt butter. In fact, this soup is completely vegan – you won’t find any butter, heavy cream, or chicken broth here. Instead, it gets its luscious creamy texture from blended cauliflower!

And as far as flavor goes, you won’t miss the cream or butter at all. Aromatics like leeks, celery, garlic, and fresh thyme create the savory base of the soup. A full pound of fresh mushrooms loads it with umami flavor, and tamari, Dijon mustard, balsamic vinegar, and a generous splash of white wine make it deliciously tangy.

Sauté the aromatic veggies and mushrooms, add the cauliflower and vegetable stock, and simmer until everything’s tender. Then, blend the soup with the Dijon and balsamic, and enjoy this yummy, all-veggie cream of mushroom soup.
