Heat the oil in large soup pot over medium heat. Add the garlic, shallot, and ginger, and cook for 1 minute, until the garlic is fragrant. Add in the onions and cook until they are translucent.
In a small bowl, mix the miso with a few tablespoons of broth and mix with a fork until you get a smooth slurry. Add that to the soup pot, along with the rest of the broth. Cook for 5 minutes until the broth is hot. Then add the lemon juice and mushrooms.
Serve warm with chopped scallions on top.
