Wash the mushrooms with care and patience. I know this can feel tedious, but it is satisfying when you wash away the dirt from which it came.
Remove the end of the stems. Not the entire stem as I notice some people tend to do, just slice the rough end off.
Slice the mushrooms and put to the side.
Heat the olive oil in your soup pot over medium heat. Add the sliced onions and cook for 3-5 minutes.
Add the salted herbs, garlic, and thyme. Cook for a minute.
Add the mushrooms and flour. Mix well. Cook for 3min.
Add the broth (I used chicken). Bring to a boil, then reduce to a simmer for 15-20min.
Prepare the croutons while the soup simmers (or you can also prepare them before!)
Add the coconut milk and bring back to a simmer.
Using a hand blender or Vitamix, blend the soup until smooth.
