What is Zenzai?

Zenzai is a traditional Japanese dessert soup made with azuki beans, mochi, or glutinous rice cake. If you’ve never had azuki or sweet red beans before, the idea of beans in a dessert might sound a little strange, but it’s a very common item to see in Asian desserts.

Texturally, the azuki beans are typically cooked down until completely soft and delicately sweetened. It pairs really beautifully with the chewy, springy texture of mochi and is served with a sweet “soup.”

You can enjoy this either hot or cold, and there are various ways you can approach making this dish. You can opt to use azuki beans made from scratch, as I did in this recipe, or you can purchase canned, prepared, sweet azuki beans.

For the mochi, the easiest way would be to use a prepared mochi, like this microwavable mochi used in my Youtube tutorial, or frozen mochi/rice cake, which can be added. You could also make your own using glutinous rice flour or spend hours beating rice with a mallet until it turns into mochi, but my preference is to go for microwavable mochi.

What Makes This Recipe Great

Japanese sweets are some of my favorites, and zenzai is no exception! It’s a snack or dessert that is typically enjoyed around January when it’s cold and wintertime. Served hot, it’s cozy and comforting, warms you up, and tastes amazing. However, it’s also delicious and served cold and can be enjoyed any time of year!

Zenzai is an easily customized dish. You can make this as sweet or as mild as you’d like, and enjoy this protein-packed, fiber-licious, bean-based dessert! It’s something different but absolutely delicious and a Japanese classic.

Ingredient Notes

  • dry azuki beans: You can use adzuki beans made from scratch or purchase a can of sweetened, prepared whole beans in a can.
  • water
  • sugar of choice: You can use brown sugar, coconut sugar, date sugar, etc. Adjust the sweetness to taste.

How to Make Japanese Red Bean Soup/ Zenzai

  1. Begin by preparing azuki beans. If using dry, bring 1 cup of beans (rinsed) to a boil with 3 cups of water. Once boiling, lower the heat to a simmer.
  2. Allow beans to cook for about 1-2 hours or until tender. Taste to test whether it’s ready.
  3. Once ready, make sure there is excess liquid among the beans. If not, add water. Do not drain!
  4. In a saucepan, add your sugar, and on low heat, stir until completely incorporated and melted down. Adjust to your taste.
  5. Serve by spooning red beans and some of the “soup” into a small bowl. Add prepared mochi and enjoy.
