Cream of Mushroom Soup

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

Cream of Mushroom Soup

Before I met Jack, I associated cream of mushroom soup with green bean casserole. I thought of it as an ingredient, not a dish on its own, and mushrooms themselves weren’t something I really sought out. But Jack may be the world’s #1 mushroom lover, and as I tried the mushroom pastas and sandwiches he loved, I discovered how delicious mushrooms could be. Prepared the right way, they become rich and savory, with an intense umami flavor.

Now, I’m a total mushroom convert, and this homemade cream of mushroom soup is one of our favorite dishes to share on cold nights. It’s far too good to hide inside any casserole, so make a batch to enjoy on its own! If you have any extras, freeze them for later, but fair warning: this soup disappears pretty quickly in our house.

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.

Cream of Mushroom Soup Serving Suggestions

If you want to take this cream of mushroom soup over the top, don’t skip the garnishes! Crunchy toppings like homemade croutons, roasted or sautéed mushrooms, and toasted pine nuts offer a delectable contrast to its smooth, luscious texture. I also like to add a sprinkle of herbs or microgreens for something fresh and a drizzle of coconut milk or olive oil for extra richness.

Serve your cream of mushrooms soup with homemade focaccia or no-knead bread, and dig in!

    This recipe is super yummy – I love nothing more than a good healthy soup recipe! I added a can of cannellini beans to bulk up the protein and then threw in spinach for even more vitamins. Then blended it all together. It was great and very filling 😊.

    I just made this. It doesn’t look as creamy or nice as yours though – texture wise it just looks a bit like puréed sauce rather than a creamy soup. It’s also very flecked (I imagine from colour of the mushroom) but yours seems to be a very light consistent colour! Not sure what I did wrong (I used same kind of mushrooms!) I did use vegetable stock instead of broth but would be surprised if that was why? Thanks!

    It tasted good – just doesn’t look appetising unfortunately!

      Hi Montana, I’m glad you enjoyed the taste – the creamy texture may vary depending on your blender (I use a vitamix so everything gets very smooth). You could try blending it a bit longer, or if it’s too thick, try adding a bit of water until it’s a creamy soup consistency. It’s a brown color, there’s no getting around that, I just put a lot of garnishes on it to help brighten up the look.

        Thanks, I put it in my smoothie blender instead and it worked a treat! Definitely gave it the smooth creaminess I was after!

    Wonder if I could blend in some avocado near the end or some other point?

      I’m not sure avocado would go well with these flavors.

    Mushrooms are on of my favorite foods, and this soup did not disappoint! I added some toasted croutons and a drizzle of olive oil as suggested and absolutely loved it. Also, I used 3 tablespoons of fresh thyme leaves instead of 2 because it is my favorite herb.

    I made this soup and it didn’t turn out anything like the photos. I wasn’t too impressed … more brown looking and very earthy flavour. I love mushrooms so I thought I’d love this but sorry 😔

      I’m sorry you didn’t enjoy this one.
