Japchae
Japchae is a glossy, savory-sweet stir-fry of chewy sweet potato glass noodles with tender beef and a rainbow of vegetables. The noodles soak up soy, garlic, and sesame oil beautifully, creating a dish that is light in feel yet deeply satisfying.
Ingredients
Noodles and beef
- 120 gsweet potato glass noodles (dangmyeon)
- 150 gbeef sirloin, thinly sliced
- 35 mlsoy sauce
- 12 gsugar
- 18 mlsesame oil
- 8 ggarlic, minced
- 1 gblack pepper
Vegetables
- 80 gspinach
- 80 gcarrot, julienned
- 100 gonion, thinly sliced
- 80 gshiitake mushrooms, sliced
- 70 gred bell pepper, thinly sliced
- 20 gspring onion, sliced
For stir-frying and finishing
- 15 mlneutral oil
- 8 gtoasted sesame seeds
Instructions
- 1
Bring a medium pot of water to a boil. While it heats, combine the beef with 15 ml soy sauce, 6 g sugar, 5 ml sesame oil, 4 g garlic, and black pepper. Toss well and let it stand while you prepare the vegetables; this short marinade is enough because the beef is sliced thinly.
- 2
In a small bowl, stir together the remaining 20 ml soy sauce, 6 g sugar, 13 ml sesame oil, and 4 g garlic to make the seasoning sauce for the noodles.
- 3
Blanch the spinach in the boiling water for 20 to 30 seconds just until wilted, then drain, rinse briefly under cold water, and squeeze out excess moisture. This keeps the strands bright and prevents the japchae from becoming watery.
- 4
In the same pot, cook the sweet potato glass noodles according to package timing, usually 6 to 7 minutes, until chewy but tender. Drain well, rinse briefly to stop the cooking, then cut the noodles a few times with kitchen scissors for easier eating. Toss immediately with the seasoning sauce so they absorb flavor while still warm.
- 5
Heat a large skillet or wok over high heat with 5 ml neutral oil. Stir-fry the marinated beef for 1 to 2 minutes until just cooked and lightly caramelized at the edges. Remove to a plate so it stays tender.
- 6
Add another 5 ml neutral oil to the pan. Stir-fry the onion, carrot, shiitake mushrooms, and red bell pepper for 3 to 4 minutes until the vegetables are just tender but still vivid and distinct. Japchae is best when each vegetable keeps its own texture rather than steaming together into softness.
- 7
Return the beef to the pan, then add the seasoned noodles, spinach, and spring onion. Toss over medium-high heat for 1 to 2 minutes until everything is evenly mixed and glossy. If the noodles seem tight or clumped, keep tossing rather than adding water; the sauce redistributes as they warm.
- 8
Turn off the heat, scatter over the toasted sesame seeds, and toss once more. Taste and adjust with a pinch more soy sauce if needed, then serve warm or at room temperature.
Nutrition per serving
Notes
- •Slice the beef across the grain for maximum tenderness.
- •Do not overcook the noodles; they should remain springy and translucent, not soft and mushy.
- •For the best texture, stir-fry the vegetables over fairly high heat so they stay bright and lightly crisp.
- •Japchae is often enjoyed at room temperature, making it excellent for meal prep or part of a larger Korean spread.
Background
Japchae originated in Korea during the Joseon dynasty and was first made as a noodle-less stir-fried vegetable dish served at court. After sweet potato starch noodles were introduced later, they became the defining ingredient, and japchae evolved into the festive dish widely loved today at celebrations and holidays.
