Ingredients (Serves 4)

– 1 medium onion, chopped
– 3 cloves garlic, minced
– 500 g (about 1 lb) fresh mushrooms, sliced (button, cremini, or a mix)
– 1 medium potato, diced (optional, for extra creaminess)
– 960 ml (4 cups) vegetable broth
– 240 ml (1 cup) unsweetened plant milk, such as soy or oat
– 1 tablespoon nutritional yeast
– 1 tablespoon soy sauce or tamari
– 1 teaspoon dried thyme
– Salt and black pepper, to taste

– Optional umami boost: a small handful of Food and Drinks dried shiitake mushrooms, soaked in hot water for 15 minutes, then sliced
The dried shiitake are optional, but they add a deep, almost meaty flavor that fresh button mushrooms cannot match. You can even pour the soaking water into the pot as extra broth.
How to Make Vegan Mushroom Soup
Step 1: Saute the Onion and Garlic
Heat the olive oil in a large pot over medium heat. Add the chopped onion and cook for 4 to 5 minutes, until soft and translucent. Starting with the onion builds a sweet, savory base for the whole soup. Add the garlic and cook for 1 more minute, just until fragrant, so it does not burn and turn bitter.
Step 2: Brown the Mushrooms
Add the sliced mushrooms to the pot and cook for 6 to 8 minutes, stirring now and then. At first they will release a lot of moisture; keep cooking until that liquid evaporates and the mushrooms start to brown. This browning step is where most of the flavor comes from, so do not rush it.
Step 3: Simmer with Broth and Thyme
Add the diced potato, if using, along with the vegetable broth, dried thyme, and a pinch of salt and pepper. If you soaked dried shiitake, add them and their strained soaking liquid now. Bring everything to a boil, then lower the heat and simmer for 15 to 20 minutes, until the potato is completely tender. The potato slowly breaks down and gives the soup its silky body.
Step 4: Blend to Your Favorite Texture
Use an immersion blender to blend part or all of the soup. Blending half the pot gives you a creamy base with plenty of mushroom pieces; blending everything gives you a smooth, restaurant style bowl. This step is optional, so feel free to leave the soup chunky if that is how your family likes it.
Step 5: Stir in the Plant Milk and Umami Boosters
Stir in the plant milk, nutritional yeast, and soy sauce. Heat the soup through for 2 to 3 minutes over low heat, without letting it boil, so the plant milk stays smooth. The nutritional yeast adds a gentle cheesy note, while the soy sauce deepens the savory flavor. Taste and adjust the salt and pepper.
Step 6: Season and Serve
Ladle the soup into bowls and finish with fresh parsley, a swirl of plant cream if you like, and a crack of black pepper. For extra texture, scatter a few Food and Drinks crunchy vegetable chips on top; they act like croutons but add more color and fiber. Serve hot with toasted bread.
Tips for the Best Vegan Mushroom Soup
– Mix your mushrooms. Combining button, cremini, and shiitake gives a rounder, deeper flavor than one type alone.
– Do not skip the browning. Mushrooms need those 6 to 8 minutes to caramelize; pale mushrooms mean a flat tasting soup.
– Want it richer? Swap half the plant milk for canned coconut milk or a homemade cashew cream.
– Skip the potato if you prefer. Blend a handful of soaked cashews with the broth instead for a low starch version.
– Make it gluten free by using tamari instead of regular soy sauce and checking your broth label.
– Add a squeeze of lemon at the end. A little acid brightens the earthy mushroom flavor.
Why Dried Mushrooms Make Vegan Mushroom Soup Even Better
Fresh mushrooms bring texture, but dried mushrooms bring concentrated umami. During the drying process, the glutamates that create savory flavor become much more intense, which is why a small handful of dried shiitake can make a whole pot of soup taste slow cooked.
For plant based cooking, that matters even more. Without butter or cream, umami is what makes a vegan soup feel satisfying instead of thin. Keeping a bag of dried shiitake in the pantry means you can add that depth to any soup, stew, or risotto in minutes, with no waste and no last minute shopping.

Frequently Asked Questions
Can I freeze vegan mushroom soup?
Yes. Let the soup cool completely, then freeze it in airtight containers for up to 2 months. Thaw it overnight in the fridge and reheat gently on the stove, stirring well, since blended soups can separate slightly after freezing.
How long does it keep in the fridge?
Stored in a sealed container, this soup keeps for up to 4 days in the refrigerator. The flavor actually improves on day two as the thyme and mushrooms continue to infuse the broth.
Which plant milk works best?
Unsweetened soy milk is the most neutral and adds the most protein, while oat milk gives a slightly sweeter, extra creamy result. Avoid sweetened or vanilla flavored milks, which will clash with the savory flavors.
Can I use only dried mushrooms?
You can. Rehydrate about 60 g (2 oz) of dried mushrooms in hot water for 20 minutes, then use both the mushrooms and the strained soaking liquid. The soup will taste even more intense, though you will lose some of the fresh mushroom texture.
