Richly flavored, this creamy mushroom soup recipe is creamy without any cream! It's a plant-based vegan mushroom soup recipe made with mushrooms and cauliflower that's also gluten-free! Easy to make and easy to freeze for busy days.
Once the days get shorter and the nights become cooler, it's soup season in my home. From my favorite carrot ginger soup to instant pot minestrone soup to chicken pho every week finds me simmering a different pot of soup. Sometimes I cook it in a soup pot on the stove top, other times in an Instant Pot or a slow cooker.
I like to make a big pot of healthy soup, use what I need, and freeze the rest for another day.
Soup is easy to make gluten-free, dairy-free, and even vegan. I can fill it full of healthy vegetables and add a protein source if I like. Soup is simply the best!

❤️ Why this mushroom cauliflower soup recipe works
- Creamy without the cream! This cream of mushroom soup is dairy-free. Instead of using heavy cream, it relies on healthy, nutrient-rich cauliflower to achieve the same creamy texture as a soup recipe made with cream.
- It's freezable. Make ahead and freeze for busy days.
- It doesn't need coconut milk to make it creamy. Cauliflower does the trick without adding any strong flavor to overpower the earthy flavor of the mushrooms.
- This is a soup that the whole family will love, it's not just for mushroom lovers!

🛒 Ingredients for plant-based mushroom soup
You'll find a complete list of ingredients with amounts in the recipe card below. But before we get to the full recipe, here are a few notes about some of the key ingredients.
- fresh mushrooms: I like to use cremini mushrooms in this recipe. They're sometimes called Baby Bella mushrooms. You can also use button mushrooms. It doesn't matter if you use brown mushrooms or white mushrooms, both will be delicious.
- leeks: for a mild flavor, leeks are more delicate and sweeter than onions.
- celery: gives a subtle, natural savory flavor to this soup recipe.
- tamari: is darker, less salty than soy sauce, is usually gluten-free, and gives this mushroom soup a strong umami flavor.
- garlic: use fresh cloves
- fresh thyme leaves: a perfect herb for this recipe.
- vegetable broth: either homemade or store-bought vegetable stock or broth
- cauliflower: thickens the soup, adding a creamy texture and extra nutrients.
- olive oil: using extra virgin olive oil to sauté the vegetables keeps this soup vegan.
🔪 How to make the best creamy mushroom soup
Here's an overview of what you'll do to make this vegan mushroom soup recipe perfectly. You'll find complete instructions in the recipe card at the end of this post.
Start by preparing all the ingredients. Thoroughly wash, then slice the leeks (white and light green parts only). Roughly chop the cauliflower into florets and dice the celery.
Slice the mushrooms, give the garlic a rough chop, and remove the thyme leaves from their stems.
Over medium-high heat, sauté the celery and leeks with ¼ teaspoon salt until softened but not browned. Add the mushrooms and cook until most of their liquid has been released (about 10 minutes.)
Next, add the tamari, garlic, and thyme to the pot and stir for two minutes. Once the garlic has softened, add the vegetable broth and cauliflower florets.
Simmer uncovered for about 20 minutes. Check the cauliflower with a fork. If it has completely softened, it's time to blend the soup. I like to add a generous squeeze of lemon juice to balance the flavors, then check to see if it needs a little sea salt and a few grinds of black pepper.
Blend until smooth. If you like it thinner, you can add a little water until you've reached your desired consistency.
❓Reader's Questions
Can I freeze cream of mushroom soup? Will it separate?
This cream of mushroom soup is made without cream, so you don't have to worry about it separating. Because the soup has been blended, you won't find that the mushrooms become rubbery, as you might if you left them whole or in larger pieces. Freeze this soup in labelled airtight containers for up to 3 months or so.
🔁 Possible variations
If you cook with wine, you can add a flavor boost of ¼ cup or so of red wine, Port, or sherry at the same time that you add the tamari.
🍳 Equipment
You'll need a
- sharp knife
- cutting board
- heavy-bottomed soup pot, or Dutch oven
- blender or an immersion blender
🍽 Serving Suggestions
Creamy soups like this mushroom cauliflower soup need crunchy toppings to balance their texture. I like to top a bowl of piping hot soup with either homemade gluten-free croutons or polenta croutons.
But don't stop there! How about any of the following soup toppers?
- toasted pumpkin seeds
- toasted sage leaves
- crispy fried sliced mushrooms
- a swirl of sour cream or vegan sour cream
- a drizzle of coconut milk
- fresh herbs
or any of the 20 or so delicious ideas in this collection of Healthy Soup Topping Ideas.
⏰ Storage Instructions
To store: Store leftover soup in a covered container in the fridge for up to 3 days. It's just as delicious on the second day!
To reheat: Reheat in a saucepan on the stovetop or in a microwave-safe bowl in the microwave.
Freeze it: Freeze this creamy mushroom soup in airtight containers for up to 3 months.
