Heat a big soup pot or sauce pan to medium high heat.
Chop your mushrooms, onions and garlic and add them and 2 tbsp of butter to the pan. Stir every so often and cook for 10 minutes to get the water out of the mushrooms and the onion and garlic incorporated.
Add 1 1/2tbsp of your thickener (arrowroot or corn starch) in a small mason jar, add in 1/2 cup of your broth and shake so there are not lumps then add to your cooked mushroom mixture and whisk it in so it thickens up.
Pour in your broth and your cooked wild rice. Add in your sea salt, pepper, thyme, coconut aminos or Worcestershire sauce and bring to a simmer for 10 minutes.
Turn off the heat and let cool for 5 minutes then add in your "cream" or choice (cashew milk, coconut milk, half and half).
Option to use your immersion blender to thicken it up a little bit, I like to do a couple pulses. Serve with parsley and cracked black pepper and enjoy!
