Spicy Bean Sprout Japchae

This might be the easiest japchae I’ve ever made. My mom taught me this simple spicy version, and it’s quickly become one of my favorite ways to cook glass noodles.

Everything cooks in one pan. As it steams, the moisture from the bean sprouts softens the noodles perfectly — no separate boiling needed.

Her little trick is saving half of the sauce and adding it at the end while sautéing everything together. It keeps the flavor bold and gives the dish a stronger spicy kick.

It’s chewy, spicy, a little savory-sweet, and incredibly satisfying. If you love glass noodles and want a quick one-pan recipe, you have to try this one.

What Is Dangmyeon?

Dangmyeon (당면) are Korean sweet potato glass noodles made from sweet potato starch. They have a chewy, bouncy texture and are commonly used in dishes like japchae and gimmari.
