Jajangmyeon (Black Bean Noodles)

Ingredients

12 ounces russet potatoes, peeled and cut into ½-inch pieces4 cups chopped onion, divided⅔ cup roasted chunjang (Korean black bean paste)2 tablespoons sugar 2 tablespoons oyster sauce 1½ teaspoons monosodium glutamate (optional)4 teaspoons cornstarch 10 ounces ground pork 2 tablespoons soy sauce 2 teaspoons grated fresh ginger 10 scallions, sliced thin½ cup canola oil 4 cups chopped green cabbage 6 ounces shrimp, peeled, deveined, tails removed, and cut into ¼-inch pieces35 ounces fresh Korean udon noodles 1 English cucumber, cut into matchsticks1 danmuji (Korean pickled daikon radish), halved lengthwise and sliced thin crosswise (optional)

Before You Begin

We prefer to use roasted chunjang for its more complex flavor; you can substitute an unroasted version if that's all you can find. Monosodium glutamate is optional but provides the sauce with deep seasoning. Fresh (or fresh-frozen) Korean udon noodles are often sold in 1-kilogram (35-ounce) packages and contain individual bundles of noodles weighing 8 to 9 ounces each; these are thinner and less chewy than Japanese udon. You can use any size shrimp here.

Instructions

  1.  Place potatoes in large saucepan and cover with water by 1 inch. Bring to boil over high heat. Reduce heat to medium-low and simmer until potatoes are al dente and paring knife inserted into them meets some resistance, about 3 minutes. Drain potatoes in colander and transfer to bowl; set aside.
  2.  Combine 2 cups onion; chunjang; sugar; oyster sauce; and monosodium glutamate, if using, in second bowl and set aside. Stir 1 cup water and cornstarch together in liquid measuring cup; set aside.
  3.  Cook pork in 14-inch wok or large Dutch oven over medium-high heat, breaking up meat with wooden spoon, until no longer pink, about 3 minutes. Stir in soy sauce and ginger and cook until fragrant, about 1 minute.
  4.  Add scallions and oil to pork mixture and cook for 1 minute. Stir in chunjang mixture and cook until onion is softened, about 3 minutes. Add cabbage, potatoes, and remaining 2 cups onion and cook until cabbage is softened, 5 to 7 minutes. Stir in shrimp and cook for 30 seconds.
  5.  Stir cornstarch mixture to recombine, then stir into sauce. Bring to boil and cook, stirring often, until sauce is thickened and glossy, about 3 minutes; remove from heat. (Jajang sauce can be refrigerated for up to 3 days.)
  6.  Meanwhile, bring 4 quarts water to boil in large pot. Add noodles and cook, stirring often, until tender. Drain noodles and rinse under hot running water, tossing gently, for 1 minute. Drain noodles again and transfer to serving bowls. Spoon jajang sauce over noodles. Serve with cucumber and danmuji, if using.

Why This Recipe Works

This comforting, umami-rich dish of fresh noodles topped with a savory black bean sauce is a beloved Korean classic that emerged from a particular subcategory of Korean cuisine known as Junghwa Yori (Korean-Chinese). It’s built around a key ingredient—chunjang—a Korean fermented black bean paste (not to be confused with Chinese black bean paste), which imparts a unique savoriness and tang. When chunjang is cooked with some oil, meats, vegetables, and seasonings, it becomes jajang sauce; when jajang is served over noodles, the dish is called jajangmyeon. (The same sauce served over rice is known as jajangbap, or black bean rice.) In this recipe, developed by Judiaann Woo, we topped fresh Korean udon noodles with a jajang sauce that incorporated potatoes, cabbage, onions, scallions, pork, and shrimp. The result was far greater than the sum of its parts, with a touch of sweetness, a hint of ginger, and an earthy depth.
