There’s a moment every autumn when the air turns crisp, the light softens, and my kitchen starts whispering comfort-food cravings. Last year, that whisper became a shout when my daughter came home from college announcing she’d gone fully plant-based. I panicked—how could I recreate our Sunday-night cream-of-mushroom ritual without the dairy? After three test batches, a soaked-cashew epiphany, and one very enthusiastic thumbs-up from the world’s pickiest 19-year-old, this luxurious vegan cream of mushroom soup was born. It’s silky, deeply savory, and crowned with the most gorgeous violet-sable swirl of coconut-cashew cream. We now serve it at Thanksgiving (no one misses the classic), ladle it over green-bean casseroles, and keep quart jars in the freezer for “emergency coziness.” If you’ve been searching for the ultimate plant-based comfort soup that still feels worthy of company, welcome home.

Why This Recipe Works

Double Umami: A mix of cremini and dried porcini creates layers of earthy depth that mimic the traditional roux without flour.
Cashew Silk: Soaked raw cashews blend into the silkiest, neutral cream—no coconutty aftertaste, just pure velvet.
No-Roux Simplicity: Skip the butter-flour dance; everything simmers in one pot, then blitz with an immersion blender.
Make-Ahead Magic: Flavor actually improves overnight, so it’s ideal for holiday prep or weekly meal plans.
Allergen-Friendly: Naturally gluten-free, soy-free, and coconut-free (cashews supply all the richness).
Elevated Presentation: A quick violet-hued cashew-cream swirl turns humble soup dinner-party gorgeous.

Ingredients You'll Need

Think of this ingredient list as a well-rehearsed choir—each voice matters, but none needs to be a diva. Quality produce and a few pantry staples create symphonic richness without any dairy.

Cremini (Baby Bella) Mushrooms – 1 ½ lb / 680 g These brown-capped beauties offer deeper, nuttier flavor than white buttons. Wipe, don’t rinse, to prevent sogginess; trim just the dry stem tips. Look for caps that are closed under the hood—gills showing means older, milder mushrooms.
Dried Porcini – ½ oz / 15 g A small handful rehydrated in hot water equals liquid umami gold. If porcini is pricey, substitute dried shiitake; the flavor skews slightly smokier but still delicious. Save the soaking liquid—it’s the secret broth booster.
Raw Cashews – 1 cup / 140 g Choose unsalted, unroasted cashews for neutral creaminess. Pieces are cheaper than whole and work perfectly. Quick-soak hack: cover with boiling water 30 minutes while you prep vegetables.
Yellow Onion – 1 large Sweet onions caramelize faster; yellow ones deliver classic savory backbone. Dice small for even cooking.
Garlic – 4 large cloves Smash, then mince to release allicin for maximum pungency. Add after onions to prevent burning.
Fresh Thyme – 2 tsp leaves (or ¾ tsp dried) Woody herbs stand up to long simmering; strip leaves by running fingers backward along stems.
White Miso Paste – 1 Tbsp Fermented soybean magic adds salt and layered umami without tasting “miso-y.” Choose mellow white or yellow; red is too assertive here.
White Wine – ½ cup / 120 ml Use something crisp and unoaked—Sauvignon Blanc or Pinot Grigio. Alcohol cooks off, leaving bright acidity to balance cashew richness.
Vegetable Stock – 4 cups / 960 ml Low-sodium preferred so you control salt. homemade stock elevates the soup from great to transcendent.
Olive Oil – 3 Tbsp A fruity extra-virgin variety perfumes the sauté; standard oil works if that’s what you have.
Sea Salt & Black Pepper Season in layers—when sweating mushrooms, after simmer, and final tweak before serving.

How to Make Vegan Cream Of Mushroom Soup With Cashews

Soak the Cashews

Place cashews in a heat-proof bowl, cover with 2 cups boiling water, and let stand 30 minutes. (Overnight on the counter works too; fridge for up to 48 h if planning ahead.) Drain and rinse; this softens the nuts for a silken blend and removes enzyme inhibitors that can cause slight bitterness.

Rehydrate Porcini

Combine dried porcini with 1 cup just-boiled water in a small bowl; steep 15 minutes. Lift mushrooms out, squeezing excess back into bowl; rinse briefly to remove grit. Finely chop and reserve. Strain soaking liquid through coffee filter or paper towel to eliminate sediment; you now have mushroom stock concentrate.

Sauté Aromatics

Heat olive oil in a heavy 4- to 5-quart Dutch oven over medium. Add diced onion; cook 4 minutes until translucent, stirring occasionally. Stir in garlic and thyme; cook 1 minute until fragrant. Push veggies to the perimeter; you’re making space for mushroom magic next.

Brown the Mushrooms

Increase heat to medium-high. Add chopped creminis plus ½ tsp salt; sauté 8–10 minutes. At first they’ll weep; once the liquid evaporates and you see golden edges, you’re building fond—the caramelized bits that equal flavor depth. Stir occasionally but give them contact time with the pot.

Deglaze with Wine

Pour in the white wine; scrape the browned bits with a wooden spoon. Simmer 2 minutes until almost dry. The acidity brightens the earthy base and prepares the pot to accept stock without any floury slurry.

Simmer with Stock

Add vegetable stock, reserved porcini concentrate, chopped porcini, miso paste, ½ tsp black pepper, and another ½ tsp salt. Bring to a boil, reduce to low, cover partially, and simmer 15 minutes. Miso melts and seasons the broth; mushrooms soften further and flavor mingles.

Blend Cashew Cream

Drain cashews; transfer to a high-speed blender with 1 cup of the hot soup broth. Blend on high 60 seconds until perfectly smooth. Pour back into pot; stir to combine. The nuts thicken the soup naturally while delivering buttery mouthfeel—no coconut milk needed.

Purée to Preferred Texture

For restaurant-smooth, immersion-blend the entire pot 30–45 seconds. Prefer a country-style bite? Blend half and leave chunky mushroom pieces. Taste and adjust salt/pepper. If soup is too thick, splash in more stock or water; too thin, simmer uncovered 5 minutes.

Finish & Serve

Ladle into warm bowls. Optional but gorgeous: whip ¼ cup soaked cashews with ¼ cup water and ¼ tsp beet powder for a violet cream; drizzle in swoops. Garnish with extra thyme, cracked pepper, or truffle oil if you’re feeling decadent. Serve with crusty sourdough for the full hygge experience.

Expert Tips

No Blender? No Problem

Soak cashews 2 hours, then simmer them directly in the soup until very soft (20 min). Mash thoroughly with a potato masher; the soup will be slightly rustic but still creamy.

Low-Fat Option

Replace half the cashews with 1 cup cooked white beans. You’ll lose a smidge of richness but gain fiber and cut calories.

Double for Crowds

Recipe scales perfectly ×2 or ×3. Use a wider pot so mushrooms brown, not steam. Freeze flat in zip bags for space-saving storage.

Umami Boosters

Stir in 1 tsp tamari, a pinch of smoked paprika, or a dash of truffle salt at the end for extra complexity without changing method.

Prevent Curdling

Cashew cream rarely splits, but if reheating rapidly, warm gently over medium-low and whisk; avoid a rolling boil.

Quick Soak Trick

Microwave cashews submerged in water for 3 minutes, then rest 10 minutes. Drain and proceed—perfect for last-minute cooking.

Variations to Try

Wild Mushroom Medley – Swap half the creminis for fresh oyster, maitake, or chanterelle. Finish with a drizzle of walnut oil.
Potato Leek Version – Add 1 diced Yukon gold and 1 sliced leek; reduce cashews to ½ cup for a lighter, brothy texture reminiscent of vichyssoise.
Curried Glow – Stir in 1 tsp yellow curry powder with the thyme and swap white wine for coconut water. Garnish with cilantro and lime.
Smoky Bacon-ish – Fold in ½ cup chopped smoked tempeh sautéed in maple syrup for a “bacon” bite and subtle sweetness.
Spring Green – Add 2 cups baby spinach during the last 2 minutes; blend for a muted emerald soup that tastes like March sunshine.

Storage Tips

Cool soup completely within 2 hours of cooking. Transfer to airtight glass jars or BPA-free plastic containers, leaving ½ inch headspace for expansion.

Refrigerator: Keeps 5 days. Flavor melds beautifully, so it’s an excellent meal-prep candidate.
Freezer: Freeze up to 3 months. Thaw overnight in fridge, then reheat gently. If texture separates, whisk vigorously or re-blend 5 seconds with immersion blender.
Make-Ahead Cashew Cream: Blend a double batch of cashew base and refrigerate 1 week or freeze in ice-cube trays; pop a cube into any soup for instant creaminess.

Frequently Asked Questions

They’ll work, but roasted nuts have a stronger, slightly sweet flavor that can overshadow mushrooms. If that’s all you have, soak and rinse thoroughly, then add a squeeze of lemon to brighten the final soup.

Yes—no flour or roux involved. Just ensure your miso and vegetable stock are certified gluten-free (some brands contain barley).

Use 1 cup canned white beans plus 2 Tbsp sunflower seeds for body, or ¾ cup coconut cream plus 2 Tbsp oat flour simmered 5 minutes. Texture and flavor shift but still luscious.

Absolutely. Use sauté function through step 5, then add stock, seal, and cook on high pressure 5 minutes. Quick-release, stir in cashew cream, and purée with immersion blender. Total time shaved to 25 minutes.

Salt is the usual culprit—mushrooms need more than you think. Add ½ tsp salt, 1 tsp lemon juice, and a pinch of white pepper, then simmer 2 minutes. Taste again; repeat until flavors pop.

Because of the low-acid cashew purée, pressure canning is required—follow NCHFP guidelines for cream soups: quarts 90 min at 11 PSI (adjusted for altitude). For safety and quality, I recommend freezing instead.
