Japchae features chewy sweet potato starch noodles (dangmyeon) tossed with colorful veggies, marinated beef, and a simple soy-sesame sauce. The key is to cook each ingredient separately for the best texture and flavor, then mix everything at the end.

Ingredients

Noodles: 8–9 oz (225–250 g) Korean sweet potato starch noodles (dangmyeon / glass noodles)

Beef 6–8 oz (170–225 g) beef (rib eye, sirloin, or tenderloin), thinly sliced

• 1 Tbsp soy sauce
• 1 tsp sugar (or brown sugar)
• 1 tsp toasted sesame oil
• 1 clove garlic, minced
• Pinch of black pepper

Vegetables (cut everything into thin matchsticks/julienne for even cooking)

• 1 medium carrot, julienne
• 1 small onion, thinly sliced
• 4–6 fresh shiitake
• 1 red bell pepper (or mix of colors), thinly sliced
• 8–10 oz (about 1 bunch) fresh spinach, washed

Sauce (for everything)

• ¼ cup (4 Tbsp) soy sauce
• 2–3 Tbsp sugar (adjust to taste – start with 2)
• 2 Tbsp toasted sesame oil
• 1 Tbsp toasted sesame seeds
• ½ tsp ground black pepper
• Optional: 1–2 cloves garlic, minced (for extra flavor)

For garnish

• 1–2 eggs (for thin egg ribbons – optional)
• Extra toasted sesame seeds

Instructions

1. Prep the beef (if using): Mix the beef slices with the marinade ingredients (soy sauce, sugar, sesame oil, garlic, pepper). Let’s sit 10–15 min while you prep veggies.
2. Cook the noodles: Bring a large pot of water to a boil. Add the dangmyeon noodles and cook according to the package instructions. This usually takes 6–8 minutes. Cook the noodles until they are soft and translucent. They should not be al dente, but fully cooked for the right chewy texture. Drain, rinse under cold water to stop cooking, and drain well. Cut noodles a few times with scissors if they’re too long. Toss with 1 tsp sesame oil to prevent sticking.
3. Blanch the spinach: In the same boiling water (or fresh water), blanch for 30–45 seconds, until wilted. Drain, rinse with cold water, gently squeeze out excess water, and cut into 2–3-inch pieces. Season lightly with a pinch of salt and ½ tsp sesame oil.
4. Stir-fry the veggies and beef. Heat 1–2 tsp of vegetable oil in a large pan or wok over medium-high heat. Cook them one by one for the best results.
5. Make the sauce: In a small bowl, whisk together soy sauce, sugar, and sesame oil. Add sesame seeds, pepper, and garlic if using. Taste—it should be sweet-salty with sesame aroma.
6. Combine everything. In a large mixing bowl, place the cooked noodles first. Then add all the stir-fried veggies and beef. Include the blanched spinach and the sauce. Toss gently but thoroughly with your hands (wear gloves if hot) until evenly coated. Adjust seasoning: more soy for saltiness, more sugar for sweetness, or sesame oil for richness.
7. Optional egg garnish: Beat eggs with a pinch of salt. Heat a nonstick pan with a little oil. Pour in a thin layer and cook it like a crepe. Flip the crepe, then slice it into thin ribbons.
8. Serve: Transfer to a platter, top with egg ribbons and extra sesame seeds. Japchae is great warm, at room temp, or cold—perfect for picnics or meal prep!
