Japchae - Korean Noodles
Description
Japchae combines chewy sweet potato starch noodles with thin strips of beef marinated briefly in soy sauce, sugar, garlic, and black pepper for subtle sweetness and depth. The beef is sliced thinly to ensure quick cooking and tenderness. Vegetables such as shiitake mushrooms, red bell peppers, carrots, green onions, and baby spinach are cooked and mixed to add texture, natural sweetness, and freshness.
The dish’s sauce blends soy sauce, sugar, minced garlic, sesame oil, and seasoning, which coats the noodles and ingredients to unify the flavors. The sautéed beef and vegetables bring savory umami and contrast against the neutral noodles. Traditionally, japchae serves as a flavorful main or side dish and is enjoyed warm or at room temperature.
Choosing tender beef cuts and handling the noodles properly by rinsing and draining well helps maintain the ideal texture. The recipe advises marinating the beef for 15-20 minutes and cooking vegetables in batches to preserve their distinct textures. Leftovers keep well refrigerated for several days but are not suited for freezing.

Instructions
Quick beef marinade:
- Cut beef into strips that are ~ 5mm thick, 1cm wide and about 5cm long (1/5" x 2/5" x 2"). If using shortribs, trim excess fat, cut the meat off the bone. Then cut each piece in half lengthwise (to form 2 "steaks") then slice into 5mm thick. (See step photos in post or video at 0.11s, Note 6)
- Marinate - Put beef in a bowl. Add marinade ingredients, then mix. Set aside marinate while you proceed with recipe, ~15 - 20 minutes is all it needs. (Note 5)
Sauce and noodles:
- Sauce - Mix the Sauce ingredients in a very large mixing bowl.
- Noodles - Cook sweet potato noodles per packet directions (normally 8 min in boiling water). Drain, briefly rinse under tap water then shake off excess water well. Add noodles into the bowl with the dressing. DO NOT MIX.
Vegetables:
- Batch 1 - Heat 2 tablespoons of oil in a large non-stick pan (30cm/12") over high heat. Cook the brown onion, white part of green onion and shiitake mushrooms with 1/2 tsp salt for 2 1/2 to 3 minutes, stirring constantly, just until starting to soften but not going golden. Pour on top of the noodles - don't mix yet!
- Batch 2 - Using the same pan still on high heat, heat 1 tbsp oil then cook the carrot and capsicum for 1 1/2 minutes, constantly stirring. Add spinach, green onion and the final 1/2 tsp salt. Keep cooking for 1 1/2 minutes until the spinach is wilted. Transfer into the noodle bowl - still don't mix!
- Cook beef - In the same pan, heat the final 1 tbsp of oil still on high heat. Add beef and cook for 1 1/2 minutes until very lightly golden and just cooked through. Add to the noodle bowl. Don't mix!
- Mix! Add most of the sesame seeds (reserve some for topping). NOW you can mix! Toss, toss, toss.
- Serve - Transfer into a serving bowl, sprinkle with remaining sesame seeds. This is meant to be eaten warm, not piping hot. Eat!
Notes
- Use tender beef cuts like short ribs, boneless rib eye, or scotch fillet; thinly slicing preserves tenderness and quick cooking.
- For economical cuts, tenderizing with baking soda before marinating helps soften the meat.
- Cook sweet potato noodles according to package instructions and rinse well to prevent sticking.
- Shiitake mushrooms add a deeper flavor; substitute with cremini or white mushrooms if needed.
- Leftovers store up to 3 days in the fridge; not recommended for freezing.
