Here's a 3-minute recipe for a homemade instant cup of soy milk soup with onion koji. This quick and easy soup recipe is perfect for breakfast.

Instant cup soups are quick and easy, so great for busy mornings. But have you thought about making your own instead of buying it at the store to make it healthier?
This recipe is super simple and quick. Just throw everything—soy milk, onion koji, water, and shimeji mushrooms—into a pot, and you're good to go in 3 minutes!
The secret to the seasoning is onion koji. It's a handy seasoning that can be used as a substitute for consommé. It takes about a week to make, but the process is super easy (click here to see how to make it).

🥬Variations

If you want to boost the nutritional value, go ahead and add some boiled vegetables.
If you store your boiled veggies the night before in containers like Tupperware, you'll save time and have much more efficient mornings.
🧅How To Use Onion Koji
Before using onion koji, stir it well from the bottom. The saltiness tends to accumulate at the bottom, so if you use it by scooping out only the top, you may feel it is not salty enough.
Also, if you are concerned about the green smell of onion koji, try heating it for a longer time.
