Ingredients
Method
- Step 1 – Marinate the Beef: Cut beef into thin strips. Combine with soy sauce, sugar, garlic, and pepper. Toss well and marinate for 15–20 minutes.
- Step 2 – Prepare Sauce & Noodles: Whisk all noodle dressing ingredients in a large bowl. Cook sweet potato noodles according to package directions (about 8 minutes), drain, rinse briefly, and add to the bowl without mixing yet.
- Step 3 – Stir-Fry Vegetables (Batch 1): Heat 2 tbsp oil over high heat. Add onion, white parts of green onion, and mushrooms with ½ tsp salt. Stir-fry 3 minutes, then transfer to the noodle bowl.
- Step 4 – Stir-Fry Remaining Vegetables (Batch 2): Add 1 tbsp oil to the pan. Stir-fry carrots and bell pepper for 1½ minutes, then add spinach and green onion tops. Cook 1½ minutes more until wilted. Transfer to the noodle bowl.
- Step 5 – Cook the Beef: Add 1 tbsp oil to the pan. Stir-fry marinated beef for 1–2 minutes until golden and cooked through. Add to the noodle bowl.
- Step 6 – Combine: Sprinkle with most of the sesame seeds, then gently toss noodles, beef, and vegetables until evenly coated and glossy.
- Step 7 – Serve: Transfer to a platter, garnish with remaining sesame seeds, and serve warm or at room temperature. Drizzle extra sesame oil for added shine if desired.
Notes
Sweet potato noodles (dangmyeon) give Japchae its signature chewy texture and are naturally gluten-free. Marinate beef briefly for flavor without toughness. Cook vegetables in batches to keep them crisp and colorful. Serve with kimchi or pickled radish for a full Korean experience.
