How to Make Mom’s Easy Japchae Recipe (Korean Glass Noodles)

Looking for an easy japchae recipe? Here is how to make my mom’s authentic Korean glass noodles.

My husband, Jacob, used to love Japchae until one day, he told my mom he loved her Japchae. And then, on every subsequent visit, my parents would bring over a Costco-sized tray. Never tell an Asian parent you love their dish unless you’re prepared to eat gluttonous amounts whenever you see them.

They may never say they love you, but food is their love language, and it’s always funny to hear similar stories among our Asian friends. Now that it’s been many years that we’ve lived away from my parents, I’m starting to add it back into our recipe rotation.

What is Japchae or Korean Glass Noodles?

Japchae (잡채) is a sweet and savory sweet potato glass noodles dish stir-fried with various vegetables, meat, and mushrooms. It used to be a royal dish and was originally served without noodles. It wasn’t until China introduced sweet potato starch noodles to Korea that it became popular among the common folk like us. Today, it’s served as an appetizer or main. You’ll find them often at potlucks, celebrations, and other get-togethers.

Mom’s Notes and Substitutions

  • You can take out the beef and fish cake and make this recipe vegetarian or vegan.
  • If you don’t add enough sesame oil to the noodles, they will stick together and break apart as you mix them.
  • Start with 4 Tbsp of soy sauce and 4 Tbsp brown sugar. Then add more soy sauce and brown sugar at a 1:1 ratio to taste. I added 1 Tbsp of each until I got the desired taste. I ended up with 5 Tbsp of each, but sometimes different brands of soy sauce and sugars are saltier and sweeter than others.
  • If you don’t like the color of the noodles turning so dark brown, some people like to add more salt instead of soy sauce.
  • My mom likes to add different colored peppers to make the dish more colorful, but you can use one type of pepper.
  • Some people add a jalapeno pepper to give it some heat.
  • It took me 3 hours to make this recipe my first time, but I was also scrambling to find all the ingredients and forgot to pre-soak my noodles. If you’re good at prepping your ingredients, it should take far less time. You have enough time to soak your noodles while preparing everything else.
