Recipe: Japchae-Inspired Spaghetti Squash

Low carb Asian noodle dish


Japchae (pronounced jap-chay) is a savory, umami Korean noodle dish I always get whenever I visit a local Korean day spa. It is one of my favorite things to eat and always conjures feelings of healthy, relaxed self care for me. 🙂 Typically, japchae is made with sweet potato glass noodles (you should definitely try it that way also!) but I’ve made this spaghetti squash version because I have piles of spaghetti squash in my winter food storage left over from my summer garden.

It’s also a great dish to practice your chopstickin’ skills on! Enjoy – and let me know in the comments if you tried japchae for the first (or 50th) time!
