This vegan creamy mushroom soup is made with oats instead of dairy and flour.

In case you haven’t noticed, I kinda have a thing for mushrooms. It’s literally a struggle for me not to include them in every single dish because I really could eat them in every meal. (Just did a quick count: they’re in 5 of my 10 latest recipes…oops.) I just love their meaty texture, umami taste, and the depth of flavor they bring to plant-based meals.

That’s why this vegan creamy mushroom soup – which calls for an unapologetically large heap of ‘shrooms – is basically my ideal soup. Fellow mushroom lovers, rejoice!

This super simple, 5-ingredient dish is low in effort and big on flavor. It showcases a brilliant cooking technique – once again, something I picked up at Natural Gourmet Institute – of using rolled oats to make a creamy vegan soup with zero dairy/coconut milk.

Sliced mushrooms, vegetable broth, oats, and chopped onion - gathered on a marble table

No, that’s not a typo. This creamy soup really uses oats instead of cream. While the oats simmer in the broth, they absorb moisture while also releasing starch. Then when you blend the soup, you get a creamy, velvety texture that’s reminiscent of cream of mushroom soup. Only vegan, flourless, and better for you!

Another highlight is the soy sauce. Just a tablespoon’s worth rounds out the flavor of the soup and makes the mushrooms really mushroom-y.

How to Blend the Soup

I recommend using an immersion blender to puree this vegan creamy mushroom soup. It’s a must-have for soup-lovers because it’s…

Space-efficient
The best way to puree soup since you put it directly in the pot and there’s no need for that messy, pot-to-blender transfer that results in splatters of hot soup everywhere
Safer for hot liquids than a standard upright blender

If you don’t have an immersion blender, you can use an upright blender. You just have to be more careful.

When using a standard blender to puree anything hot, it’s super important that steam has a way to escape. Remember to take out the removable center of the blender lid before blending. If the steam is trapped inside, the top will blow off and the soup will go everywhere, staining your kitchen and potentially causing skin burns. (This happened to me when I was a teenager, hence why I haven’t made marinara since).

Description

A dairy-free creamy mushroom soup made with oats instead of dairy and flour! (Adapted from The Complete Vegan Cookbook)

Ingredients

Scale

2 tablespoons extra virgin olive oil
1 pound cremini mushrooms, stemmed and sliced
1 medium onion, diced
1/2 teaspoon fine sea salt
4 cups vegetable broth
1 tablespoon soy sauce or tamari
1/4 cup old-fashioned rolled oats
Freshly ground black pepper, to taste
Dill and/or spiced pumpkin seeds, for serving (optional)

Instructions

Heat the oil in a medium, heavy-bottomed pot over medium heat. Add the mushrooms, onion, and salt, and cook until the mushrooms are softened, stirring occasionally, 10 to 12 minutes.
Add the broth, soy sauce, oats, and pepper. Cover the pot and bring to a boil. Then reduce the heat to low and simmer covered for 25 to 30 minutes, stirring occasionally.
Using an immersion or upright blender (see Note below), purée the soup until completely smooth. Taste and re-season if needed. To serve, garnish with pepper, dill, and spiced seeds, if desired.

Notes

When using a standard upright blender to puree something hot, it’s important that steam has a way to escape. Remember to take out the removable center of the blender lid before blending, and cover the opening lightly with a kitchen towel while blending. If the steam is trapped inside, the top will blow off and the soup will go everywhere, staining your kitchen and potentially causing skin burns.
