Japchae (잡채), which means mixed vegetables in Korean, is a popular dish in Korean restaurants. It is normally served as a side dish (banchan, 반찬). However, I add plenty of vegetables in my recipe to make it nutritious even as a main dish. This is an easy dish I also enjoy bringing to potlucks since it is usually loved by everyone.

Japchae Ingredients

Red bell peppers, green onions, onions, shiitake, spinach, and carrots are all commonly used in japchae. However, I also like to add some red cabbage because it’s nutritious and for its pop in color. While my japchae recipe is vegan, you could add some bulgogi for a meat component. Another commonly added protein is egg garnish (dalgyal jidan, 달걀 지단).

Quick One-Pan Method

Traditionally, the vegetables in japchae are cooked and seasoned separately. However, for the sake of convenience, the ingredients in my recipe are consecutively added and cooked together in the same skillet. The ingredients with a longer cook time are added first (e.g. red bell pepper, red cabbage). And while not normally added in japchae, red cabbage is used in my recipe for its nutritional value and pop of color.

Hope you enjoy!


Japchae mise en place



As with most of my recipes, I use coconut sugar as the sweetener. Not only is it a natural sweetener, but it is also a healthier sugar substitute. It contains a bit of inulin which decreases the likelihood of post-meal sugar spikes and so may be a healthier option for people with diabetes. I also prefer its softer sweetness. However, you could always substitute coconut sugar with plain sugar or brown sugar in my recipes.
