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!

    My gf and her son both got sick a few days ago and she told me they’re basically surviving off of soup! I just texted her the link to this recipe because I know she’ll love this, thank you!!!

    Looks amazing! Could I replace the tamari with coconut aminos?

      Yep! I love coconut aminos, I used it interchangeably with tamari.

    Yum. Looks great. What do you think would go best to amp up the protein content? Brown lentils? Probably wouldn’t look pretty, but would still taste great.

    nice dish, thank you, mushrooms always add a subtle flavor that elevates the rest of everything else, esepcially in a soup!

    Loved this, very delicious! Thanks Jeanine, I love all your recipes. I let this soup summer a little longer to thicken up and served it as a pasta sauce with sautéed mushrooms and sautéed green beans for crunch. Friends loved it and I couldn’t get enough of it. The vinegar and mustard at the end add just the right amount of tang. Yum!

    Just made this. Had lots of mushrooms in the fridge and happened to have all the ingredients for this. It’s delicious!!! I didn’t have high expectations because I still associate cream of mushroom soup with a can of Campbell’s soup. This was delicious and creamy. I kept some extra mushrooms after sautéeing, so I could top the soup with it. It gave some nice texture along with crunchy croutons and pine nuts.

    I adore mushrooms in any form. They are very healthy in fact, although nearly no-one notices that. We collect it in a forest, put in a jar with salt or dry it on a thread. Magic legends about it make it to be used as must have during Xmas. Yummy! ☺
