Japchae

Japchae (잡채) is a Korean dish of stir-fried glass noodles with vegetables. It was served at banquets and holiday feasts and enjoyed at the Joseon royal court. Today it means dangmyeon noodles with carrot, onion and often meat, but for three centuries japchae was a dish of assorted vegetables with no noodles at all. ¹²³

A king's favourite. The court chronicle of King Gwanghaegun from 1608 records japchae as his favourite dish, which is why researchers date it to the seventeenth century. According to the magazine of Korea's Hansik institute, high officials exchanged japchae as a gift. The name means a gathering of assorted vegetables: the critic Hwang Gwanghae argues that «jap» stands for variety, not confusion, and that the variety is a compliment. ¹³

Japchae without noodles. The cookbook Eumsikdimibang of 1670 gives the oldest recipe: more than 20 ingredients, among them raw cucumber, radish, mushrooms and mung bean sprouts, and steamed and torn bellflower root, bracken, angelica, eggplant and pheasant, served with a sauce of pheasant broth, strained soybean paste and wheat flour. Its author Jang Gyehyang added that the choice of greens is free. A court record of 1796 names bellflower and mung bean sprout japchae, and an 1896 recipe mixes sprouts, watercress, tripe and raw beef with mustard. ¹³

How dangmyeon arrived. Dangmyeon came from China: Hansik reads «dang» as the Tang dynasty, and the noodles were also called homyeon. They reached Korea with Chinese migrants at the end of the nineteenth century, especially after 1882. In the 1920s and 1930s factories were built in Pyeongan and Hwanghae provinces; when many Chinese left after the Manchurian Incident, Koreans took the factories over, and production centred on Pyongyang, with much of it exported to Japan. ¹

Noodles take over. Japchae with glass noodles first appears in cookbooks in the 1920s and became popular in the 1950s, while the old vegetable version was still printed until the 1940s. A 1957 book mixes the boiled noodles with everything else at once, while a 1960 book seasons the other ingredients first and adds the noodles last. Over the centuries cooks used mushrooms, meat, fish, beef tongue, sea cucumber and pear, seasoned with soy sauce, sesame oil, garlic, sugar, vinegar or mustard, and garnished with egg strips and pine nuts. ³

The official recipe. For the PyeongChang 2018 Games six government bodies promoted a simple japchae for four. 100 g of glass noodles are boiled for five minutes and rinsed in cold water; 80 g of carrot and 100 g of onion are stir-fried with 2 g of salt, 20 g of chives are cut into 5 cm lengths, and 80 g of burdock is simmered for ten minutes in water with soy sauce and sugar. The noodles are stir-fried until dry with 12 g of unrefined sugar, 12 g of brown sugar, 36 g of soy sauce and 26 g of oil; the sugar keeps them from going soggy and makes them shine. ²

The noodles themselves. Dangmyeon are starch noodles, and Korean food researchers make them from different starches, including mung bean and potato starch. Dry mung bean glass noodles have 351 kcal, 86 g of carbohydrate and only 0.16 g of protein per 100 g, so almost all the protein in japchae comes from the vegetables, meat or egg added to it. ⁴⁵

Ready-made japchae. The government recipe suggests dividing cooled japchae into single portions, wrapping them and keeping them in the fridge, then reheating each one in a microwave for about a minute. A 2026 study of frozen ready-to-eat foods in Korea found Bacillus cereus, a bacterium that can cause food poisoning, in several ingredients, japchae among them, and called for stricter handling. ²⁶

Why it matters to you. Japchae is easy to make vegetarian: the official recipe simply replaces meat with other vegetables. Keep leftovers chilled and reheat them well, especially with frozen ready meals. If you want the oldest version, make it from mixed namul with no noodles.
