This is the best vegan cream of mushroom soup ever! It's dairy-free, gluten-free, and nut-free too. Combining 3 delicious things- creamy food, mushrooms, and soup! How can you go wrong? When I was a kid, my favorite thing to eat was Campbell’s cream of mushroom soup. It has been over 20 years since I have had a can, but I can easily say this dairy-free alternative is much better than Campbell’s!
If you are a mushroom lover like I am, you won’t be able to get enough of this recipe! I am the only one in my house that loves mushrooms, so I usually make this for lunch when I am the only one home. It makes about 6 servings, but I have to stop myself from eating the whole pot in one sitting.

🧾 Ingredients and substitutions
- Mushrooms - Any mushroom that you like will work well - white, button, and portabella mushrooms are all good choices. My favorite ones to use for this recipe are crimini, also known as baby Bellas.
- Oil - any neutral-flavored cooking oil will work well. Canola oil, light olive oil, or refined coconut oil are all good choices.
- Salt - for flavor. Feel free to decrease for a low sodium option.
- Garlic Powder - for flavor. You can use onion powder, or a clove of fresh garlic instead if you wish.
- Paprika - for flavor.
- Black Pepper - for flavor. You can also use a dash of cayenne pepper or red pepper flakes for a little heat.
- Plant-Based Milk - for creaminess. Any plain flavored vegan milk like oat milk, soy milk, Ripple, or cashew milk will all work well.
- Starch - to thicken the soup. You can use potato starch, corn starch, or even white flour dissolved in water. You can also use a vegan roux to thicken this soup. For a roux, you will need vegan butter or oil and flour.
🥄 Instructions
- Start by washing and cutting up mushrooms into small bite-sized pieces.
- Add them to a soup pot with some oil and sprinkle them will salt. (The salt flavors the mushroom and helps it to release its juices to flavor the broth).
- Saute the mushrooms for about 5 minutes until they release their juices.
- Then add the plant milk and spices. Heat until it just begins to boil.
- Mix potato (or corn) starch with cold water and pour it into the soup. (This will thicken it quickly).
- Stir consistently for about 1 more minute until your soup is thick and creamy.
🥣 How to thicken the soup
This vegan cream of mushroom soup can be thickened one of 2 ways. The easiest way is to use corn starch and cold water. (This method also makes it gluten-free).
The other way it to make a roux out of a ¼ cup of oil and a ¼ cup of flour. Heat the oil and flour in a saucepan until it gets bubbly and starts to brown slightly then slowly add the broth to the rue, stirring constantly, until it thickens. The method using the roux adds, gluten and fat, but it also adds a rich creaminess to the soup!
👩🏻🍳 Pro tips
- Potato starch gives it a slightly better texture and flavor than corn starch, but if you don't have it corn starch will work well too.
- If you are using thicker soy milk to make this like Silk brand or equivalent, use 2 cups milk and 2 cups water.
- You can also use unsweetened plant-based milk in this recipe.
- Do not use vanilla flavored plant milk.
- You may also thicken this soup by adding 1/4 cup of oil and 1/4 cup of flour to the bottom of a second soup pot. Heat the flour and oil for a minute then slowly ladle in the hot broth stirring with a whisk between each scoop of liquid until all of the soup is added and it begins to bubble.
- If using the method with oil and flour, still add the extra cup of water, just don't add the cornstarch.
