This Low-Carb Double Mushroom Soup is not only the best-tasting dish I’ve ever made out of old mushrooms in the fridge that were close to past-their-prime status, but it’s also the best mushroom soup I’ve ever made, and it’s low-carb gluten-free, and a phase one soup for the South Beach Diet!

This is also the soup that will make you remember how much you love your immersion blender, if you have one. If not, you can puree the soup in a food processor or regular blender; it’s just a bit easier with the immersion blender.

My soup was inspired by Anthony Bourdain’s Mushroom Soup recipe on Serious Eats. If you don’t know about Anthony Bourdain, he’s a charming food personality who I think would be great fun to meet! I did add my own touches, using some dried mushrooms along with the fresh ones for even more flavor, skipping the sherry, and adding a drizzle of balsamic vinegar on top. I think this will become my new go-to soup for a first course for dinner parties, it’s that good.

Soak 1 cup dried mushrooms in boiling water for about 30 minutes, then drain and save the soaking liquid. If needed, strain the liquid with cheesecloth or a coffee filter. Wash 12 ounces of fresh mushrooms, then drain and cut into thick slices. I used regular white mushrooms, which were showing a few signs of age, but they were still wonderful in this soup. One large onion is cut into thin slices and then sauteed in olive oil (or butter, your choice.) Then the fresh mushrooms are added and cooked for a bit longer. Then add dried mushrooms, reserved mushroom water, chicken stock and a bit of dried parsley are added and the soup is simmered for one hour. After an hour, season soup with salt and pepper and taste for flavor. When the liquid tastes perfect to you, puree with an immersion blender, food processor, or regular blender, and serve with a drizzle of balsamic vinegar. If you have guests, sit back and wait for the compliments!

Low-Carb Double Mushroom Soup (Inspired by Anthony Bourdain's Mushroom Soup)

Low-Carb Double Mushroom Soup has two kinds of mushrooms and extra flavor from balsamic vinegar.

Ingredients:

  • 1 cup dried mushrooms (I used dried shitakes, but use any type of mushrooms you like the flavor of.)
  • 2 cup boiling water
  • 4 T butter, olive oil, or a combination of butter and olive oil, whichever you prefer
  • 1 large onion, cut into thin half-slices
  • 12 oz. fresh mushroom, thickly sliced (I used regular white mushrooms but I think I might use brown Crimini mushrooms next time.)
  • 4 cups chicken stock (I used my homemade chicken stock; see notes)
  • 1 tsp. dried parsley (or use 2 tsp. fresh parsley if you have it)
  • salt and fresh ground black pepper to taste (I didn’t use much salt.)
  • 2 T good quality balsamic vinegar, for drizzling over soup when you serve it

Directions:

  1. Bring 2 cups water to a boil, then put dried mushrooms into a plastic bowl and pour boiling water over.
  2. Let mushrooms soak 30 minutes, while you prep other ingredients.
  3. Peel onion and cut in half lengthwise, then cut each half into thin slices.
  4. Wash mushrooms, drain in colander, and then cut into thick slices.
  5. Heat 2 T butter or olive oil in the bottom of a heavy soup pot big enough to hold all the soup.
  6. Saute onions about about five minutes, until they’re well softened but not browned.
  7. Add 2 more T butter or olive oil.
  8. Add sliced fresh mushrooms and cook about 8 minutes, until mushrooms have released all their liquid and it has mostly been evaporated.
  9. Add dried mushrooms, mushrooms soaking water (strained through cheesecloth or a coffee filter if it needs it), chicken stock, and dried or fresh parsley.
  10. Bring soup to a very gentle simmer and cook uncovered for about one hour.
  11. After an hour (when soup should have reduced by at least 1/4) taste for flavor, and add salt and fresh ground black pepper as needed.
  12. If the soup doesn’t seem flavorful enough, cook a bit longer to reduce a little more.
  13. When soup has a good mushroom flavor, puree either by using an immersion blender to puree soup in the pot, or by carefully removing hot soup to a food processor or or regular blender to puree. (Be very careful if using food processor or blender. Puree in batches, and don’t overfill the container.)
  14. Serve hot (reheat if needed after pureeing in food processor or blender).
  15. Drizzle a little good quality balsamic vinegar over each bowl of soup as you serve it.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
This delicious Low-Carb Double Mushroom Soup that’s not thickened with flour or cornstarch is a great soup for low-carb or Keto diets. The use of butter isn’t recommended by the South Beach Diet, but personally I’d use some butter with the olive oil for flavor. Everything else here is low-glycemic and I loved the idea that the soup had no cream, but tasted very creamy. If you want to be completely faithful to South Beach or for a version of this soup that’s Paleo or Whole 30 approved, just use all olive oil and I’m sure the soup will still be great. Even with some butter, I think this is a good phase one soup for South Beach. And if you’re following another type of low-carb diet and want to use only butter, that can only make it taste better!

  1. Thanks everyone, glad you are liking this. And I love calling the immersion blender a "boat motor", so perfect!

  2. Great soup! Luckily oyster mushrooms and criminis were on sale so I used those. And instead of drizzling with basalmic, I seared chicken in olive oil and basalmic and added right before serving. Thanks!

  3. I love creamless creamy mushroom soup – the drizzle of balsamic vinegar definitely makes this soup. I recently had roasted red pepper soup with a swirl of balsamic vinegar on top too and it was so good.

  4. Thanks afaust! Your version sounds great.

    Jeanette, I think balsamic is one of the best condiments ever for soup!

  5. YUM! I love mushrooms, I will have to try this for sure. Thanks Kalyn!

  6. Hi, have made this soup 3 times, using different mushrooms, and adding a dry sherry when the mushrooms exude their juices. All that is left is the delicious essence of the sherry. Easy recipe that freezes well, great with a side salad and crusty bread to mop up anything left in the bowls.
    Thanks!

  7. Love that you posted this! I never even thought about making my own. I see recipes often that call for cream of mushroom, but I don't like the processed, metallic taste from the canned version. This would be perfect!

  8. Could this be made in a pressure cooker? I'm a pressure cooker newbie so not sure how to go about that without instructions!

    • It can probably be made in a pressure cooker, but I am not enough of a pressure cooker expert to give instructions without trying it, sorry. I can't promise I'll try it, but I'll add it to my list! (Unfortunately it's a big list!)
