  • 1 tablespoon extra virgin olive oil
  • 1/4 cup onion - white onion, chopped
  • 1 cup mushrooms - dried mushrooms such as oyster, shiitake or a mix. 1 cup is 1 ounce weight
  • 8 ounces mushrooms - button mushrooms, chopped
  • 1 1/2 cup vegetable broth
  • 1/4 cup white wine such as a chardonnay
  • 1/4 teaspoon dried tarragon
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon ground black pepper
  • 1 1/2 cup unsweetened dairy-free milk, warmed


  • Bring 2 cups of water to a boil.
  • Place the dried mushrooms (not the button mushrooms) in a medium sized bowl. Pour the boiling water over the top so that they can become reconstituted. Set aside.
  • In a frying pan heat the oil over medium-high heat.
  • Saute the onions for about 5 minutes.
  • Add the chopped button mushrooms and saute for another 5 minutes.
  • Drain the reconstituted mushrooms.
  • Add the exotic mushrooms and the button mushroom mixture to a slow cooker.
  • Add the vegetable broth, white wine, tarragon, salt and pepper.
  • Cook on low 3 to 4 hours.
  • Let cool about a half hour.
  • You may reserve some mushroom pieces for sprinkling over the top as in my photos but you do not need to do this.
  • Pour the mushroom mixture in a blender and blend until smooth.
  • Pour into a big pot (or bowl for the microwave) and add the non-dairy milk.
  • Heat through on low heat on the stove top.
  • Taste to see if you would like more salt or pepper.


Best not frozen.
