This simple mushroom soup is thickened with a bit of potato for a hearty, delicious, easy-as-pie soup with a texture that's thick enough to be filling but made so without any cream. Feel free to use any kind of mushrooms you like, whether the simple cremini or button mushrooms, or shiitake, portobello, or others. A combination of mushrooms can be especially flavorful.

Serve it with a green salad and a hunk of crusty bread for an easy, healthy dinner. With a few quick substitutions, it can also be a suitable soup for vegetarians by opting for veggie stock and vegans if you use veggie stock plus oil instead of butter. Olive oil would be great.

This dairy-free vegan cream of potato soup also is thickened without any cream or milk. You can thank the potatoes for some of that creaminess and the use of a hand-held blender, food processor, or high-speed blender for achieving a smooth texture. Just remember, since you'll be processing hot soup, process in batches if you're not using a hand-held blender, and place a kitchen towel over the blender to stop any potentially burning splatters. Alternatively, you can let the soup cool before pureeing it.

Ingredients

  • 1 pound mushrooms
  • 2 tablespoons butter, or olive oil
  • 1/2 teaspoon fine sea salt, plus more to taste
  • 1 onion
  • 3 cloves garlic
  • 1/4 cup dry sherry
  • 1 pound potatoes
  • 6 cups chicken broth, or vegetable broth
  • Black pepper, freshly ground, to taste

Steps to Make It

  1. Gather the ingredients.

  2. Rinse the mushrooms clean and pat them dry. Trim off and discard any dried stem ends. Roughly chop the mushrooms (don't be too fussy about the chopping; they get puréed in the end).

  3. In a large pot, melt the butter or heat the oil over medium-high heat. Increase the heat to high and add the mushrooms and salt. Cook, stirring frequently until the mushrooms release their liquid and start to brown, about 5 minutes.

  4. Meanwhile, chop the onion and the garlic. Add the onion to the mushrooms and cook, stirring frequently, until the onions are soft, about 3 minutes. Add the garlic and cook, stirring, until fragrant, about 1 minute.

  5. Meanwhile, peel and roughly chop the potatoes.

  6. Add the sherry to the pot and cook, stirring about 2 minutes.

  7. Add the potatoes and broth and bring to a boil. Reduce the heat to maintain a steady simmer and cook until all the vegetables are extremely, falling-apart tender, about 10 minutes.

  8. Use a hand-held blender to completely purée the soup. Or, carefully whirl it in batches in a blender or food processor In any case, process the soup much longer than you think necessary—at least 2 or 3 minutes for each batch—to get a supremely smooth texture.

  9. Add salt and freshly ground black pepper to taste.

  10. Serve the soup hot, garnished as you like with freshly chopped parsley, chives, or thyme, for example.

  11. Enjoy!

    Use Caution When Blending Hot Ingredients

    Steam expands quickly in a blender, and can cause ingredients to splatter everywhere or cause burns. To prevent this, fill the blender only one-third of the way up, vent the top, and cover with a folded kitchen towel while blending.

    Variations

    • Of course, if you feel like swirling in a bit of cream at the end for a richer, more luxurious effect, you can. Sour cream, crème fraîche, or plain Greek yogurt would be good, too.
    • Spice it up with a couple of drops of your favorite hot sauce; add some green herbal notes with a drizzle of extra virgin olive oil.
    • Add a couple of tablespoons of chopped fresh herbs such as parsley, thyme, rosemary, or chives, or a combination thereof.
    • Crunchy croutons would be delicious as well.
