This is not your ordinary vegan mushroom soup! Mushrooms may taste meaty, but they are not a significant source of protein, which is why I added beans to this blended mushroom soup recipe. Beans also add creaminess, fiber, and iron, transforming this dairy-free soup into a healthful and satisfying plant-based dinner the whole family will enjoy.

This hands-off Easy Creamy Mushroom Soup recipe is perfect for the holidays - Thanksgiving and Christmas. It requires no babysitting so you can give your full attention to preparing your entrées. Plus, you can make this soup ahead of time. It's good for up to 5 days and is quick and easy to reheat for serving.

This healthy mushroom soup does not skimp on flavor. Miso and mushrooms are loaded with umami, packing in lots of flavors. Plus, miso is a fermented food, so it's great for gut health.

This Easy Vegan Creamy Mushroom Soup recipe was inspired by my 8-ingredient protein-rich vegan Butternut Squash Soup, as well as this creamy, dairy-free Easy Vegan Tomato Basil Soup on this site.

👩🏼‍🌾 Ingredients

Garlic, mushrooms, lemon juice, shallot, cashews, vegetable broth, fresh rosemary, fresh sage, butter beans, mellow miso, and lemon juice.

A blend of mushrooms adds varying textures and flavors to this creamy mushroom soup. Add a mix of shiitake mushrooms and oyster mushrooms or maitake mushrooms, in addition to brown button mushrooms (cremini, baby bella). 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.
Use a good quality vegetable broth for the best flavor. An excellent store-bought option is the Imagine or Pacific brands. If you have Better than Bouillon at home, you can use that as well. Opt for lower sodium broth for a healthier mushroom soup.
Raw cashews bring a velvety texture to this vegan Easy Creamy Mushroom Soup and make it feel more substantial. You do not need to soak the cashews if you own a high-speed blender. Otherwise, soak them briefly while you prep everything else. Either add them to a saucepan, cover with water, and boil for 10 minutes. Or place them in a coffee mug covered with boiling water for 20 minutes.
Butter beans, cannellini, navy, or Great Northern beans transform this vegan mushroom soup into a complete meal. Plus, they make vegan soup creamy without the need for unhealthy heavy creams! They also pack in protein, fiber, and iron, making this a healthy weeknight dinner.
Fresh sage and rosemary add a citrusy and woodsy depth of flavor. Use fresh thyme instead of sage as desired.

🍄 Substitutions

Mushrooms - use a variety of mushrooms (shiitake mushrooms, oyster mushrooms, maitake mushrooms, or brown button mushrooms), or use only cremini (baby bella) instead as needed
Fresh herbs - Fresh rosemary, thyme, or sage give the best flavor, but dried herbs will also work. Use one-third the amount of dried herb for the fresh herb called for in the recipe, or 1 teaspoon dried for every 1 tablespoon fresh.
Sage - use 1 ½ teaspoons fresh thyme leaves (about 2 sprigs) instead
Beans - use butter beans or white beans (navy, cannellini, or Great Northern). Butter beans add the creamiest texture, but Great Northern is the highest in protein.
Cashews - use soaked sunflower seeds, tahini, creamy unsweetened non-dairy milk, or coconut cream or milk instead as needed
Shallots - use one large yellow onion instead and cut into wedges for baking

📖 How to Make Easy Vegan Mushroom Soup

This is an overview. The full recipe is at the bottom of the post.

Preheat the oven to 400ºF.

Mushrooms, rosemary, sage, shallot wedges, and a head of garlic tossed in olive oil, salt and pepper in a white baking dish.

💡 Expert Tips

For roasting: Spread the ingredients onto a baking tray, leaving enough room between the mushrooms for even browning. (You may need two baking sheets.) Make sure all the ingredients are evenly coated with olive oil, salt, and pepper, and toss them every 10 minutes. Brush or pour a drizzle of oil directly into the cracks of the head of garlic, and wrap the bulb with aluminum foil for best results. Remove the rosemary sprig once lightly browned. Add the leaves to the blender and discard of tough stems.
For a creamier soup: Use 1 cup of raw cashews instead of ¾ cups.
To make cream of mushroom soup that can be used as a base in other recipes, use more cashews and less broth, or add cornstarch or arrowroot dissolved in cold water when reheating until the desired thickness.
Storage: Refrigerate cooled leftover Easy Creamy Vegan Mushroom Soup in an airtight container for up to 5 days.

🙋🏽‍♀️ Recipe FAQs

What is the best plant-based milk for creamy soups?

Full-fat coconut milk is a popular choice for creamy soups, especially those with an Asian or tropical profile. It will add a slight coconut flavor. Cashew milk works well as it is naturally velvety and has a neutral flavor. Oat and soy milk better mimic the creamy consistency of dairy milk, and soy has the added benefit of additional protein. Use unsweetened options for savory dishes.

How can I thicken the soup without cream?

Create a slurry using cornstarch or arrowroot dissolved in a small amount of cold water. Slowly stir this into the soup and bring it to a simmer. As it heats, the soup will thicken.

Can you freeze mushroom soup?

This soup can be frozen in a freezer-safe container for up to 3 months. Freeze in single-serve cubed containers for ease and quick thawing. Reheat in the microwave or on the stovetop. The texture will be slightly different, but it will still be enjoyable.
