Cook the soba noodles in boiling water for about 5-7 minutes until the noodles have softened. Drain the noodles and run them through cold water to prevent them from continuing to cook and to keep them from sticking to each other. Set aside for now.

In a medium sized pot, heat vegetable broth over medium heat. Once the vegetable broth is boiling, add the sliced mushrooms and cook them until they’ve softened.

Next, add the miso paste to the broth. Stir to evenly incorporate the miso paste in the soup. The soup will appear cloudy.

Add the soba noodles and grated carrots, and cook them until they become warm.

Serve the soup warm.
