This 30-minute Vegan Japchae is a healthy, meatless version of the popular Korean glass noodles stir fry. My vegan, gluten-free version has all the traditional flavors from shiitake mushrooms, spinach, scallions, and onions, with an easy homemade japchae sauce. An authentic, quick & easy meal for weeknight dinners or to share with friends!

What is Japchae?

Korean japchae (잡채) is a stir-fry dish made with glass noodles. Japchae translates to “mixed vegetables” because of the way it is prepared. It’s stir-fried Korean sweet potato starch noodles (glass noodles) with a distinct soy/sesame oil sauce and lots of veggies. It’s a very casual dish enjoyed around the holidays.

What Makes This Recipe Great

This traditional Korean noodle dish is typically loaded with veggies, pork, and glass noodles, and topped with an egg. The sauce is a sweet and savory sesame oil sauce that gives the recipe so much flavor. 

My healthy spin turns this classic Korean glass noodles recipe into Vegan Japchae with just a few simple swaps and no loss in flavor! 

This meatless, healthier version is just as tasty but completely vegan and vegetarian. It’s a beautiful dish that is perfect for large crowds and celebrations. 

What are Korean Glass Noodles?

Korean glass noodles or sweet potato starch noodles have a very unique texture. They are packaged dry and become very springy and soft once cooked. Made with sweet potato starch, glass noodles are naturally gluten-free and essential to making any kind of japchae! 

You can easily find Korean glass noodles at any Korean grocery store, or Asian grocery store. You can also find it online if you don’t have access to an Asian market.

The Ultimate Celebration Food!

Japchae is commonly enjoyed around the Lunar New Year as glass noodles symbolize a long life. However, it’s common to find japchae at celebrations and gatherings like birthdays and family dinners too. 

Growing up, japchae was always prepared in large quantities and I suspect it’s a great go-to party food because it’s really easy to make!

Alongside japchae, you’ll often find kimchi, pajeon (or Korean pancakes), bulgogi, kimbap, and all kinds of ban chan, or side dishes.  There’s usually quite a lot going on at the Korean dinner table!

Ingredient Notes

Making this Vegan Japchae is much easier than you might think. Traditionally all of the vegetable ingredients are sautéed individually and tossed with the glass noodles to combine. Here are some of the traditional japchae ingredients we’ll be using:

Japchae Noodles: Also called sweet potato starch noodles and Korean glass noodles. You can find them in most Asian markets or online. 

Veggies: Carrot, sweet onion, shiitake mushrooms, and spinach.

Egg Substitute: I like to use vegan JUST “egg” for this recipe, optional. 

Garnish: Use sesame seeds and scallions to garnish.

Japchae Sauce

Gluten-Free Soy Sauce: I like the brand Tamari for gluten-free soy sauce.  

Coconut Sugar: I like the Wholesome brand. You can also use other granulated sugar as an easy swap. 

Sesame Oil: I like this brand and use it for all of my recipes that call for sesame oil. 

Garlic: Use freshly minced garlic or a jar of minced garlic. 

Salt and Pepper: Use to taste.

Quick Method
