Jajangmyeon (자장면; 짜장면) is the Korean version of this dish. In addition, the brown colour of the sauce is from the use of chunjang (a salty, black-colored paste made from roasted soybeans), rather than soy sauce. Jajangmyeon may also feature a variety of diced seafood rather than pork.

The vegetarian versions generally call for soybean paste (酱) of any sort instead of soy sauce, since the tofu chunks are larger and need more structure. Low-fat dieters often use ground, skinless chicken for the meat portion since ground turkey is not very popular in Asia, and a halal version is often made with ground beef or lamb.
