I know sweet potatoes and beans combined with Asian seasonings sounds like a crazy combination. You are just going to have to trust me on this. This soup is seriously delicious!
It is also fast and easy to make, filling, and frugal.
I pulled this soup together in under 20 minutes. I was able to do that because I had cooked rice on hand. If you don’t have cooked rice you can add 1 cup uncooked basmati rice and an additional 2 cups of liquid and let the rice cook while you are making the soup, but you will want to let the rice get a 5 – 10 minute head start before you add the sweet potatoes.
If you don’t have mirin in your pantry, you can substitute a sweet juice like white grape juice or apple juice. You can save money on mirin, rice vinegar, soy sauce, and sesame seed oil by shopping at an Asian market.
