It’s also nutrient-dense thanks to a generous amount of mushrooms, fresh herbs, garlic, and cashews. No cream or dairy needed for this dreamy cream of mushroom soup.
And despite being gourmet and fancy enough for a dinner party, this mushroom soup comes together easily and reheats well, making it a great meal prep option.

Why this recipe works
A velvety bisque texture.
Three techniques give this vegan mushroom soup a luxurious, velvety consistency and rich mouthfeel that will have your guests convinced it’s made with cream.
First, a portion of the soup is blended. This is an easy way to creamify any soup or stew, and a technique I use often, like in my Creamy White Bean Soup. Not all of the soup is blended though, so you get textural variation: silky smooth with bites of chewy mushrooms, the best of both worlds.
Second, a half cup of raw cashews are added to the portion of soup that gets blended. As you may know, raw cashews, when blended, add an incredibly creamy texture and richness.
Third, the recipe doesn’t add too much vegetable broth (you can always thin the soup out later if you wish).
Serious savory flavor.
Mushrooms naturally have a meaty depth, but this is no ordinary mushroom soup. It’s an umami powerhouse thanks to a mixture of fresh mushrooms, mushroom stock made from dried mushrooms, soy sauce and miso paste.
Each spoon is packed with a layered depth of flavor and coats your whole mouth with a rich, savory mouthfeel (the essence of umami!). Even my mushroom-averse partner was floored when he tried it and asked to have a big bowl of it for dinner.
PS: If you love the sound of these flavors, don’t miss out on my rich and super savory Mushroom Gravy during the holidays.
Gourmet but easy.
The flavors and textures in this soup will make your taste buds sing. It’s fancy enough to serve at any dinner party, and is particularly perfect as a starter for Thanksgiving and Christmas dinners.
At the same time, this vegan mushroom soup is easy to make, so you can even make it for a weeknight dinner if you want. It reheats fabulously, so it’s a great option to make on a Sunday or Monday and enjoy for a few days (if it lasts that long!).
Ingredient notes
Fresh mushrooms. Using a blend of different mushrooms adds varying textures to this creamy soup, so it’s far from a one-note cream of mushroom soup.
We love this soup with a mix of shiitake mushrooms and oyster mushrooms or maitake mushrooms, in addition to your everyday brown button mushrooms.
Where to buy: You can find a large selection of mushroom varieties at Asian grocery stores, farmers markets, and well-stocked grocery stores like Whole Foods or Sprouts.
Dried mushrooms + mushroom stock (optional). All mushrooms are rich in umami, but dried mushrooms are particularly so. Here, dried mushrooms are briefly soaked in water, then the resulting mushroom stock is added to the soup (in addition to veg broth) for enhanced savoriness.
The rehydrated dried shrooms are also added to the soup along with the fresh mushrooms.
Substitute: If you don’t have dried mushrooms or want to skip this step, this vegan mushroom soup is still great without them. For details, check out the FAQ section below.
Alternatively, if you have my cookbook, The Vegan Instant Pot Cookbook, there’s an excellent mushroom broth in Chapter 1 that would make this soup sing even more!
Soy sauce & miso. Mushrooms are already savory superstars, but when you add fermented soy products (e.g., soy sauce and miso), you really supercharge the flavor. Each bite is packed with a rich depth of flavor that’s often missing in plant-based food.
Vegetable broth. Use the best-quality vegetable broth available to you. An excellent store-bought option we love is from the Imagine Organic brand. If you have Better than Bouillon at home, you can use that as well (use a pinch less of salt).
Cashews. Blended and soaked raw cashews bring a velvety, bisque-like texture and make it feel more substantial than a side dish soup. No need to soak the cashews either!
Substitute: Allergic? Check out the FAQ section below.
Fresh herbs. Fresh thyme and rosemary add a lovely woodsy depth of flavor here.
Substitute: You can sub sage for either herb. If you don’t have access to fresh herbs, use a teaspoon each of the dried herbs, but it won’t have the same flavor.
Tip: Near the holidays, many grocery stores sell packages of “poultry herbs,” which combine rosemary and thyme with sage or marjoram, so you don’t have to buy all the herbs separately.
Step-by-step instructions
If using homemade mushroom stock, cover the dried mushrooms with room temperature water. Weight to submerge and soak for 30 minutes. Strain the liquid through a sieve, keeping the stock. Wash the rehydrated mushrooms well and slice.
For fresh mushrooms, slice them (e.g., cremini or shiitake) or tear them into pieces with your hands (e.g., oyster or maitake mushrooms).
In a Dutch oven or large soup pot, heat the olive oil over medium-high. Add the diced onions and cook until starting to soften. Add the garlic and cook for 1-2 minutes.
Now add the vegan butter. Once melted, add the sliced/torn mushrooms (and rehydrated mushrooms, if using).
Cook for about 5 minutes, or until shrooms are softened. Pour in the white wine and scrape up any browned bits, simmering until the smell of alcohol has dissipated.
Pour in the vegetable broth and homemade mushroom stock (if using; don’t pour in the last tablespoon, as it’s sediment heavy). Add the bundle of herbs and simmer, covered, for 15 minutes.
Scoop out 1/3 to 1/2 of the soup and transfer it to a stand blender. Add the cashews, soy sauce, and miso, and blend until the soup is creamy and smooth. Pour this blended soup into the remaining soup in the pot.
Stir well and simmer for 5 to 10 minutes, until the flavors have developed and soup has thickened a bit.
Tips for making this recipe
Use a variety of mushrooms.
Any time I make a mushroom-heavy dish, like vegan mushroom risotto or vegan mushroom stroganoff, I find I enjoy it most when I use at least two, if not more, different varieties of mushrooms.
This adds variation in texture as well as flavor (e.g., shiitakes are umami-rich and meaty, oyster mushrooms are more delicate, maitake mushrooms taste subtly like chicken).
And if chanterelle mushrooms are in season, if you can spring for a couple of those, they’re outrageously buttery and delicious (beware: they are pricy though).
If needed, soak the cashews briefly.
If you don’t have a high-powered blender, soak the cashews while you prep everything else. Just add them to a saucepan, cover with water, and boil for 10 minutes.
This ensures the cashews get fully pulverized when blended and you don’t end up with cashew bits in your soup.
If using dried mushrooms, get rid of the grit.
Please follow these steps so your soup is smooth and grit-free!
1) After soaking the dried mushrooms, strain the stock through a fine mesh sieve to get rid of any larger dirt particles.
2) To wash the rehydrated shrooms, add them to a bowl, cover with fresh water, and agitate them to release any dirt. Repeat a few times.
3) Finally, when adding mushroom stock to the soup, don’t pour in the last tablespoon, as it’s usually sediment-heavy.
Adjust the texture to your taste.
This soup is definitely on the creamy side, and thickens as it rests. If you want a thinner soup, add a bit more broth. When reheating leftovers, if desired, add a splash or two of vegetable broth or water to loosen.
Frequently Asked Questions
No, you can omit them and the soup will still be great, but make a few changes.
1) You won’t have any homemade mushroom stock, so use 4 cups (960 mL) vegetable broth instead of 3 cups (720 mL).
2) To compensate for the loss of flavor from the mushroom stock, I recommend adding 1/2 teaspoon porcini mushroom powder when you add the vegetable broth (affiliate link). It adds great savory depth of flavor to all kinds of soups, stews, and lentil dishes.
I haven’t tried this product, but a few of my readers have used Trader Joe’s multipurpose umami seasoning as a substitute for porcini mushroom powder in other recipes.
3) If you want to add extra mushrooms (since you’re not adding the rehydrated mushrooms), use 20 ounces (570g) of fresh mushrooms instead of 16 ounces. But this is totally optional.
Yes! Just be sure to use tamari or gluten-free soy sauce instead of standard soy sauce, which is fermented with wheat.
Replace the wine with 1/4 cup (60 mL) vegetable broth + 1 tablespoon sherry vinegar or white wine vinegar, or just skip this deglazing step.
You may want to finish the soup at the end with a squeeze of lemon juice or one of the above vinegars to brighten the soup.
If you’re okay using coconut milk, try 1 cup (120 mL) of “lite” coconut milk.
We did try a mixture of 1 cup ( cannellini beans and 1/2 cup (120 mL) creamy unsweetened plant-based milk. This worked decently, but it was less creamy and less magical in flavors and more bean-forward.
You could also try adding a boiled Russet potato.
After the soup simmers covered for 15 minutes, transfer 1/2 to 2/3 of the soup to a large bowl and set aside. Now use an immersion blender and blend the remaining soup in the pot until creamy. Pour the reserved unblended soup back in and stir to combine.
Personally, I eat it like a main dish, but always with a slice or two of good-quality toasted bread (a creamy soup loves a bread dipper!). I like serving a simple green salad on the side for good measure.
If you want to add some protein, a great pairing would be some cooked white beans, lightly dressed with olive oil, lemon zest and juice, salt, and pepper.
This is also a great soup to serve as a side dish for holiday dinners, like Thanksgiving or Christmas, or any kind of dinner party.
If you’re looking for a gourmet soup and salad pairing, either this Kale and Brussels Sprouts Salad or this Roasted Butternut Squash Kale Salad would be good!
Store cooled leftovers in the fridge for 5 to 6 days. You can freeze this soup, though the texture will be slightly different.
I like to freeze the soup in single-serve Souper Cubes (affiliate link) so they defrost very quickly.

Creamy Vegan Mushroom Soup
Ingredients
- 1 oz (28g) dried porcini mushrooms or other dried mushrooms (optional)*
- 16 ounces fresh mushrooms, ideally a variety, such as cremini, shiitake, oyster and/or maitake**
- 1 tablespoon extra virgin olive oil
- 1 large sweet onion, finely chopped
- 8 garlic cloves, finely chopped
- 2 tablespoons vegan butter (or more olive oil)
- Kosher salt and freshly cracked black pepper
- ½ cup (120 mL) dry white wine***
- Bouquet garni: 1 large sprig of rosemary, 2 sprigs of thyme, and 2 bay leaves****
- 3 cups (720 mL) good-quality vegetable broth (4 cups if not using homemade mushroom stock)
- ½ cup (70g) raw cashews
- 1 tablespoon white miso paste (or red miso for a more robust taste)
- 1 tablespoon soy sauce or tamari (use tamari for GF)
- ¼ teaspoon Dijon mustard (optional)
- 1 small handful of fresh chives and/or parsley, chopped
Instructions
- Optional – make mushroom stock: Place the dried mushrooms in a bowl and cover with 1 ½ cups (360 mL) room temperature water. Place a smaller bowl or something heavy on top to ensure they stay submerged. Soak for 30 minutes, or until softened.
- Scoop out the mushrooms. Strain the liquid through a fine mesh sieve to catch any sediment, reserving the stock.Add the rehydrated mushrooms to a bowl of water and agitate with your hands. Drain the water and repeat a few times until the sediment is gone. This ensures the grit won’t make it into the soup. Slice mushrooms and set aside.
- For fresh mushrooms like cremini and shiitake, slice them (remove shiitake stems). For oyster or maitake mushrooms, tear them into strips with your hands, discarding any tough ends.
- Heat a Dutch oven or soup pout with the olive oil over medium-high heat. Add the onions with a pinch of salt, and saute for 4 to 5 minutes, or until starting to soften. Add the garlic and cook for another 1 to 2 minutes. Add the butter to the pan, and once melted, add the fresh mushrooms and rehydrated dried mushrooms, if using. Cook for about 5 minutes, until softened. Season with salt and pepper at the end.
- Pour in the white wine and use it to scrape up any browned bits on the bottom of the pot. Simmer for 3 to 4 minutes, or until the smell of alcohol has dissipated and some of the liquid has bubbled off.
- If using, pour in the mushroom stock but reserve the last tablespoon or so, as it’s usually sediment-heavy. Add the vegetable broth too (use 4 cups if not using mushroom stock). Add the bouquet garni and bring to a boil. Cover, reduce the heat, and simmer for 15 minutes.
- Scoop out ⅓ to ½ of the soup (about 2 ½ cups or 550 to 600g), including some mushrooms but not the bouquet garni. Transfer this to a blender and add the cashews, miso and soy sauce. Start slowly then move to high speed and blend until smooth.
- Stir the blended soup back into the remaining soup in the pot. Bring to a simmer and simmer for 5 to 10 minutes, until the flavors have developed and the soup has thickened slightly. Season with salt and pepper. If you want a slight pop of acidity, add the Dijon mustard. Remove the bouquet garni.
- Ladle soup into serving bowls. Top each with a tiny drizzle of good-quality olive oil, if a little extra richness is desired, and garnish with a small handful of chopped parsley/chives.

OMG, this soup is off the charts! I used Tito’s in place of the white wine, red miso and freshly ground organic cashew butter. Easy to make and decadent! Hats off to you, Chef!
Mimi, So glad to hear you loved this recipe! Thanks for your lovely review :)
This is a delicious, flavorful soup. I had two large baked potatoes in my fridge that I added at the end. I couldn’t wait to eat it for lunch the next day. I used all cremini mushrooms and will experiment with others the next time.
We appreciate your feedback and support, Victoria. Thank you for leaving a review!
This was SO good! I didn’t time my homemade bread well so the first bowl was on its own and I wasn’t even mad about not having bread to dip in it. Definitely making a double batch next time!
Awesome, Rachel. Thanks for your comment and for taking the time to review!
Oh so yum! We moved it. Made it for dinner and lunch but we just finished it all! I didn’t have all the different mushrooms or white wine but the substitutes worked really well. Now I am going to really get the ingredients and make it again.
Just to give my background- we non-Vegan but we just prefer vegan recipes as they are just lighter. So give this a shot if you like a good mushroom soup.
P.s. Signed up the annual meal plan as well.
Hi Shruti, thank you for sharing! So cool to hear you’ve been enjoying the RPL recipes despite not being vegan. And thanks for signing up for the meal plan! :)
This is the absolute perfect cozy soup. After blending up the cashews I just stuck my immersion blender (carefully) in the pot itself and gave it a few whizzes. Beautiful texture. Great tip with adding the mushroom powder if we don’t have dried mushrooms on hand. I definitely used that.
Thank you for your lovely comment, Katie! It makes us happy to know that you enjoyed the recipe. :)
I have made this soup five times since Thanksgiving!!! It was easy to prepare and it takes gourmet.
We’re over the moon to hear you enjoyed the recipe, Megan. Thanks for your kind words!
My vegan and gf and non vegan family thought this was the best mushroom soup ever. We always have mushroom soup for Christmas Eve dinner and this really is delicious, flavorful and creamy. Tip: make a double batch but use two pans so you get good caramelization.
We’re over the moon to hear everyone enjoyed the recipe, Ellen. Thanks for your kind words!
I am allergic to cashews! Is there a good substitute for them?
Hi Lynne, this answer can actually be found in the FAQ section! But for convenience I’ll leave it here:
“If you’re okay using coconut milk, try 1 cup (120 mL) of “lite” coconut milk.
We did try a mixture of 1 cup ( cannellini beans and 1/2 cup (120 mL) creamy unsweetened plant-based milk. This worked decently, but it was less creamy and less magical in flavors and more bean-forward.
You could also try adding a boiled Russet potato.”
Enjoy!
I slightly adapted the recipe because of my husband’s issues with sulfites. Although he is not a fan of creamy soups, he was surprised at how good this one is. Thank you!
We’re over the moon to hear you two enjoyed the recipe, Joëlle. Thanks for your kind words!
I made the creamy mushroom soup for the first time, and it will become a regular in my rotation. My husband and I both love it. I did make the mushroom broth too. It’s so creamy that it could be used anytime where you need a “can” of cream of mushroom soup when trying to revamp an old favorite recipe.
Hi Laurie, we’re delighted you and your husband are big fans of the soup!
This soup is absolutely delicious. Creamy, full of flavor, with so many luscious textures in your mouth. I would definitely serve this to company. And it’s really easy to make!
Hi Marilyn, thank you so much for your kind review! :)
Absolutely delicious! Family’s review: “tastes like something from a gourmet restaurant!” I didn’t use bouquet garni since I didn’t have any so I simply added some poultry seasoning, nor did I use dried mushrooms. Used a mix of baby portobello and meaty chantarelles, and even pan fried some chanterelles until crispy and added as garnish. My only issue…15 minutes prep time?? I’m a very proficient home chef and there’s no way…it takes that to simply wash and prep the mushrooms, not to mention chopping onion and all that garlic, and prep other ingredients.
We’re so glad the whole family enjoyed the soup, Shelly! And we’re sorry the prep time wasn’t accurate in your experience.
I loved this recipe!! Since I don’t really like cashew I used sunflower seeds instead and it was still creamy and delicious. Thank you for this recipe
We’re glad that worked out for you, Hannel! Thanks for the kind review.
This soup is delicious!
I had half the amount of fresh mushrooms but then made the mistake when adding stock of putting in the full amount so went back and made up the quantities. Still delicious but will have to do it 100%
a real heart warming, cold buster
We’re happy to hear you enjoyed the soup, Michaela! Hopefully next time it comes out perfectly :)
This was incredible! I picked up a variety of 8 different mushrooms from my local farmers market and this was the perfect way to use them. So much thought and consideration of flavour went into this recipe, sincere thank you for taking the time to write it and publish it with photos.
I used pure cashew butter in place of cashews and bundled dried herbs into a cheese cloth as I didn’t have fresh and the flavour cooked through beautifully. In place of wine I use a quarter cup white wine vinegar and diluted with water. I also us ghee as I’m not vegan. Turned out wonderfully.
We’re happy you enjoyed the soup, Erika! Thanks for the lovely review.
I made this soup last night without the dried mushrooms. My 20 yr old son could not stop raving about it. Needless to say, my husband and I loved it too. It has a fabulous flavor and texture and went perfectly with a simple green salad.
Thank you so much for the lovely review, Tracy! So cool to hear the soup was well-loved by the whole family.
This soup was SOOoO good..and I’ll add that I didn’t use garlic or onions as someone was questioning above and it was still INCREDIBLE flavor! My only gripe is that it didn’t serve 4 as a main… more like 2 to 3 in my opinion..but otherwise fabulous !
We appreciate your feedback and support, Nicole. Thank you for leaving a review!
Thank you for this wonderful recipe! We’ve decided to have Mushroom Mondays and use this as one of the rotations regularly.
That’s so cool to hear, Ani! We’re glad you love the soup.
I made this last night. I accidentally simmered a little too long and ended up with a soup “concentrate” but the flavor is wonderful and i can add a little veggie stock to thin it out a little. T he flavor is fantastic on this soup and I am thinking i could add a little tofu or noodles …. thank you…really yummy!
Hi Andrea, shucks! We hope you’re able to thin it out to your liking. Thanks for taking the time to leave a review, we’re glad you loved the flavor!
This is 10 out of 10, remind me french cuisine ☺️
Thank you for this magic soup, it is perfect for frosty autumn eve’s!!
Thanks for the lovely feedback, Aygul!
