Creamy Vegan Mushroom Soup With Cashews (Easy and Delicious)

This vegan mushroom soup with cashews is so delicious and easy to make. This pureed soup is pure comfort food. Give this a try if you’re looking for plant-based soup recipes, like this vegan cream of cauliflower soup, which is another tasty option.

Ingredients and Substitutions

This soup tastes like it’s full of cream and butter, but the creaminess actually comes from cashews that have been soaked and then blended. The cashews provide tons of creaminess and act as the perfect dairy substitute in this vegan mushroom soup. 

Mushrooms and thyme are a classic flavor combination, so fresh thyme is my herb of choice in this recipe. If you don’t have any fresh thyme you can substitute dried thyme, basil, or parsley.

Nutritional yeast gives the soup a slightly “cheesy” flavor that pairs well with creaminess of the blended cashews. It also enhances the flavor of the mushrooms. If you’re not a fan of nutritional yeast, or simply don’t have any, you can omit it and the soup will still be delicious.

How to Make Vegan Mushroom Soup With Cashews

Start by soaking the cashews. To do so, place the cashews in a bowl, then pour freshly boiled water over the cashews and allow them to soak for 1 hour before draining and rinsing.

While the cashews are soaking, cook the mushrooms and onions in a large pot along with olive oil, chopped garlic, and thyme. The secret flavor booster in this soup comes from cooking the mushrooms and onions in olive oil until they’re caramelized. That golden caramelization adds a lovely depth of flavor to this soup, so I definitely wouldn’t skip that step. 

Once the mushrooms and onions have been cooked to golden, caramelized perfection, you can reserve a few of the mushrooms to use as a garnish if you like. Next you’ll blend the soaked cashews with water, then add the cooked mushrooms and onions before blending once more.

The last step is to add the mushroom purée to the pot along with more water, salt, pepper and nutritional yeast, then simmer on low heat until hot.

    I substituted about 1/4 cup for part of the water. It was great. I found it was even better the second day.
