Here are a few more reasons we love this recipe and you will too:

Ingredients

This soup is packed with earthy mushrooms and flavorful herbs. The ingredients are simple, but each one plays a pivotal role in creating the final, delicious result. Here’s what you’ll need:

• Cashews – These are the foundation of this creamy soup. When blended with hot water they create a dairy free heavy cream. Homemade cashew cream provides a creamier texture than other dairy-free milk options (like almond milk) and doesn’t have a strong flavor like full-fat coconut milk.

• Olive Oil – A high-quality olive oil is used for sautéing, contributing to the soup’s base flavor.

• Assorted Fresh Mushrooms – The combination of cremini mushrooms and wild mushrooms deliver a complex, umami depth.

• Aromatics – Yellow onion and garlic are essential for building the flavor.

• Soy Sauce or Tamari – This brings an extra umami kick, subtly enhancing the mushrooms’ natural savory notes. Be sure to use gluten free soy sauce if gluten free!

• Fresh Herbs – Bay leaves and freshly chopped herbs add brightness to the soup.

• Seasonings – Simple yet essential, salt, and cracked black pepper are all that’s needed for seasoning.

• Protein Powder or Flour – Protein powder helps thicken the soup (while creating a nutritionally well-rounded dish). All-purpose flour can be used in its place.

• Dry White Wine – An optional ingredient for added depth, or you can use more veggie broth if you prefer. I like to use a dry Pinot Grigio in this soup. Not all wines are vegan, so be sure to use one that is vegan-friendly.

• Vegetable Broth – This forms the liquid base of the soup.

• Balsamic Vinegar – A final touch to balance the creaminess with a hint of tanginess. Don’t skip this! It brings all the flavors together.

Substitutions

Here are some simple substitutions to make sure you can still enjoy this soup with the ingredients you have on hand:

• Mushrooms – You can use any brown mushrooms you have on hand from baby bella mushrooms to porcini mushrooms. 

• Olive Oil –This can be substituted for your favorite vegan butter.

• Vegetable Stock for Wine – If you’re not using wine, vegetable stock is a great alternative to maintain the soup’s rich flavor profile.

• All-Purpose Flour for Protein Powder – If you don’t have dairy free plain protein powder, you can use 2 tbsp of all purpose flour in it’s place. This will help thicken the soup.

• Cashew Cream –This can be substituted for full-fat coconut milk or coconut cream. The soup will take on a different flavor if this is used. You can also use thicker dairy-free milk like oat milk or soy milk, however, the soup won’t be as creamy. 

Helpful Equipment

• High-Speed Blender – For creating the smoothest cashew cream, a high-speed blender is your best friend.
• Large Pot or Dutch Oven – Ideal for sautéing and simmering all your ingredients together.
• Immersion Blender – This tool is perfect for blending the soup directly in the pot, although a regular blender works just as well if you handle it carefully.

Step By Step Instructions

Exact ingredient quantities are listed in the recipe card below.

STEP 1: Prepare the Cashew Cream. Soak your raw cashews in hot water using a high-speed blender. This will form the base of your creamy texture. Let them soak for 15-20 minutes to soften.

STEP 2: Cook First Batch of Mushrooms. With a portion of olive oil heated in a large pot, sauté a quarter of your mushrooms until they’re beautifully browned, then set them aside. These will serve as a garnish for a lovely textural contrast.

STEP 3: Sauté Onions and Remaining Mushrooms. Utilizing the same pot, add in the remaining olive oil, onions, mushrooms, and aromatics. Cook until the mushrooms are tender, releasing all their flavors into the mix over medium heat.

STEP 4: Thicken the Soup. Sprinkle in your thickening agent, the dairy-free Plain Protein Powder or your substitute flour, to give the soup its body. If using, the white wine comes next, adding an additional layer of complexity.

STEP 5: Add Broth and Simmer. Pour in your vegetable stock and allow the soup to simmer, melding all the flavors together. Blend the cashew cream and add half to the pot.

STEP 6: Blend the Soup. After removing the bay leaf, use your immersion or stand blender to puree the soup until it reaches a silky smooth consistency.

STEP 7: Final Touches. Stir in balsamic vinegar and the rest of the cashew cream, reserving some for garnish, and warm through. 

STEP 8: Serve! Spoon the reserved mushrooms on top, drizzle with cashew cream and sprinkle with more fresh herbs.

📌 TIP: After blending, you can adjust the thickness to your liking with extra broth if necessary.

Serving

Serve this creamy vegan mushroom soup in your go-to bowls alongside buttered, crusty bread (perfect for dunking). Top everything off with a sprinkle of fresh parsley and fresh thyme. 

It makes for a cozy weeknight dinner or a nourishing meal on a chilly fall evening. 

When served smooth without the whole mushrooms on top, it transforms into a rich vegan cream of mushroom soup recipe — an ideal, dairy-free substitute for the canned cream of mushroom soup in your green bean casseroles or as a base for other rich, savory dishes. 

This soup fits beautifully on a festive Thanksgiving table, offering a cozy vegan option that doesn’t compromise on taste or texture!

Storage

This soup stores well in the fridge. Keep it in an airtight container in the fridge for up to 5 days.

It’s also freezer-friendly for up to 2 months. The texture may change slightly if frozen. Make sure to cool the soup down before you store it and reheat it gently to maintain the creamy texture.

Helpful Tips

• Soak Cashews in Advance – Soak the cashews in hot water for at least 30 minutes. This will make them blend up even creamier.

• Garnish – Use the reserved sautéed mushrooms and lots of fresh herbs to add more mushroom flavor and brightness to the soup.

• Blending Until Very Smooth – Be sure to blend the soup until there are no more mushroom pieces visible. This will create the best, silky texture.
