What is Zenzai?

Zenzai is a traditional Japanese dessert soup with a slightly sweet taste 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 sweet 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 unique Japanese dessert either hot or cold, and there are various ways you can approach making this simple 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, cold zenzai is perfect during warmer months and can be enjoyed any time of year!

This homemade version of Zenzai is an easily customized dish and served in small serving bowls. You can make this warm soup as sweet or as mild as you’d like, and enjoy this protein-packed, fiber-licious, bean-based dessert that promotes good health! It’s something different but absolutely delicious and a traditional dessert for Japanese families, especially during cold seasons but is also available year-round.

  • water
  • sugar of choice: You can use brown sugar, coconut sugar, date sugar, etc. Adjust the sweetness to taste.
