Begin by sauteing the diced garlic, diced yellow onion, cut butternut squash, and maiitake mushrooms on medium to high heat with just enough water (1 cup) added to the bottom of the pot so that the ingredients do not stick to it.
While sauteing add :black-pepper, red chili-flakes, and 1 Tbsp of miso paste, and saute until everything is incorporated and the butternut squash starts to turn a little soft. (As the water evaporates from the bottom of the pot, add little amounts of water while sauteeing to keep the bottom of the pot stick free).
Add the cut potatoes and celery to the pot then add water until all ingredients start to float in the water (~2 inches above the level of where the food lays in the pot).
Add turmeric, garlic powder, ground cinnamon, nutmeg, oregano, paprika, and basil. Stir the mixture until the spices are incorporated.
Let the soup boil until the potatoes soften then add the green onions, nutritional yeast, and remaining 3 Tbsp of miso paste.
Blend the soup (preferably with an immersion blender because of convenience, but a regular blender will do) and use an extra couple small basil leaves as garnish.
Serve and Enjoy:)
