Soup is such a comforting meal. It can be the beginning of a larger meal or the entree itself. Just add crusty bread and a salad.

In this recipe, slow cooker mushroom soup is turned up a notch by adding the power of exotic mushrooms!

You know? Those wild dried mushrooms that you have always wanted to try. It all turns out rich, beautiful, creamy, and easy.

This crockpot recipe has a wonderful creamy base and combines all the characteristics of a perfect fresh homemade mushroom soup.

It is one of my favorite low-maintenance dishes, and it doesn’t even take that long to slow cook.

So, fresh button mushrooms are used, but there is also a mix of dried mushrooms because they have a more intensified flavor than the fresh ones.

They also enrich the natural taste of button mushrooms.

Chef Tips:

  • There are small packages for sale that contain a beautiful blend of earthy dried mushrooms such as Shiitake, Oyster, or even Wild Porcini.
  • You only need a small 1-ounce bag to make this fantastic soup.
  • Look for a dry forest blend with a good mix of savory, umami-rich flavors of mushrooms.
  • Shiitake and oyster mushrooms are especially great because of their firm texture and robust nutty flavor. It makes all the difference in this recipe.
  • I reconstitute the dried mushrooms by briefly pre-soaking them in warm water. They will reabsorb the moisture and plump up.
  • You can reserve the soaking liquid for other soups, stocks, or sauces. Leave it out for this recipe, though, because it can be overpowering with the mushrooms that are already in there.
  • It’s about balancing those deep earthy flavors with a tad of sweetness and combining the heartiness of the rest of the ingredients.

How Do You Make Wild Mushroom Soup?

  • This recipe starts briefly at the stove.
  • First, sauté the onions to soften them and release their natural sweetness before adding them to the slow cooker.
  • Then stir in the fresh mushrooms and sauté for five minutes. It allows some of their moisture to evaporate, soften their texture and intensify their delicate natural flavors.
  • Add to the slow cooker along with the rest of the ingredients. Cook low and slow for 3 to 4 hours.
  • Let cool and blend to a creamy mushroom soup. Keep a few mushrooms out before blending if you’d like to spinkle some on top as in the photos.

Cooking the right type of mushrooms slow in vegetable broth, with a tad of Chardonnay wine and seasoned with salt, pepper, and tarragon will make the aroma of the mushrooms shine but with that hint of subtle sweetness in the background.

Then add non-dairy cream at the end over low heat, and it infuses that creamy richness, but without the guilt!

Ingredients
  

  • 1 tablespoon extra virgin olive oil

Instructions
 

  • Bring 2 cups of water to a boil.

  • Add the chopped button mushrooms and saute for another 5 minutes.
  • Drain the reconstituted mushrooms.

  • Heat through on low heat on the stove top.
  • Taste to see if you would like more salt or pepper.

  4. I have been blogging for just a few months but already feel the need to go back and re-shoot my old recipe photos as well :). Amazing you got to do that – beautiful photos! I love the recipe – I have been a little intimidated by those exotic mushrooms so I might give them a try. I don’t have a slow cooker though – could I do this on the stove top over low heat?

  10. This soup looks delicious, I imagine the coconut oil really adds a lovely creaminess. Funnily enough, I have also been trying to go back through my archives and re-do some of the (in hindsight, terrible) photos. It’s proving a very good excuse to make those dishes again šŸ™‚

  12. I am not supposed to have any oils, so could I just use a bit of veggie broth for the sauteing?

  16. Hi Ginny,

    Followed the link here from my desk top start-up page. My dear friends are vegan so I am interested in learning some recipes for them. Especially if the are great for the freezer!! Two questions, if you don’t mind: 1. – non-dairy unsweetened milk ( almond, soy, rice??? )
    2. – what size slow cooker did you use.
    Looking forward to going through your blog.

  17. Hi Rie, So glad to have you here. Unsweetened non-dairy milk would be soy, almond, coconut – the ones that you find in the refrigerated section in the grocery store. I use Silk – a lot. There are so many varieties now and I didn’t want someone to accidentally use sweetened. They are clearly marked on the cartons.
    The slow cooker size I used was the smaller 2 1/2 quart one but you could go a bit larger to accommodate a size that you have. Thanks for your interest!

  18. Do I have to blend it or can I have it more like a stew? What would you suggest if I didn’t want to blend it?

  25. Do you really discard the mushroom soak water? Could you use that in place of the vegetable broth? If not in this soup, how about reserve the liquid for something else?

    I made a mushroom soup not too long ago, and Hubby wanted it to be creamy. This may be the way. I used Sherry in the previous recipe that I made and I think that was the real key to flavor. I am looking forward to trying yours.

  26. Yes, you really discard it SueC. If you don’t mind the concentrated flavor of these mushrooms then you could use it in something else. I often use a dry white wine in my soups and I much prefer the taste to Sherry. It’s not so ‘sweet’. I’m so glad you are going to give this a try.
