Tips & Notes
You can adjust the flavor intensity by modifying the amount of chicken bouillon and soy sauce.
Separating the white and green parts of the Japanese long onion and adding them to the pan at different times creates both mellow sweetness and crisp texture.
Slice chicken breast against the grain for even texture and tenderness.
Use low to medium heat to avoid burning or drying out the meat.
Substitute chicken breast with chicken thigh or tenderloin if preferred.
You can also use maitake, enoki, or king oyster mushrooms instead of shimeji.

"I’m a fun-loving chef and devoted foodie, so captivated by Hokkaido’s incredible variety of ingredients that I decided to make it my permanent home. I’ve been living here for 20 years. In spring, I forage for wild vegetables; in summer, I camp; in autumn, I hunt for mushrooms; and in winter, I ski. I’m an active explorer who chases seasonal flavors and gourmet experiences all across Hokkaido—even if it means spontaneous long-distance trips. My motto is: “If the night is fun, tomorrow will surely be even better!” I focus on creating recipes for flavorful appetizers that liven up the evening and hearty main dishes that make you want to keep reaching for more rice."
