Step‑by‑Step Instructions for Japchae
Step 1: Prep Ingredients
Begin by soaking sweet potato noodles (dangmyeon) in hot water for 30 minutes, allowing them to soften. While the noodles soak, thinly slice your beef and chop the mixed vegetables (like carrots, spinach, and bell peppers) to prepare for quick stir-frying. You’ll want everything ready to ensure a smooth cooking process.
Step 2: Stir-Fry Beef
In a large pan or wok, heat 2 tablespoons of sesame oil over medium-high heat. Add the sliced beef to the pan in a single layer; cook for about 3-4 minutes or until the beef is nicely browned and no longer pink. Once cooked, remove the beef from the pan and set it aside to keep it warm and juicy.
Step 3: Cook Vegetables
Using the same pan, add a bit more sesame oil if needed. Toss in your chopped vegetables and stir-fry them for about 3-5 minutes, or until they are tender yet still vibrant and crisp. Stir frequently to avoid burning, and look for a lovely glossy finish as the oil coats the veggies, enhancing their natural colors.
Step 4: Combine Noodles
Drain the soaked sweet potato noodles and add them to the pan with the cooked vegetables. Next, fold in the previously cooked beef and drizzle with about 4 tablespoons of soy sauce. Gently toss everything together using tongs or a spatula, ensuring the noodles soak up the flavorful sauce and everything is well combined, approximately 2-3 minutes.
Step 5: Finalize Dish
Taste your delicious Japchae and adjust the seasoning as needed, adding more soy sauce or sesame oil for depth. Once everything is heated through and well-mixed, garnish with sliced green onions before serving. This will add a fresh touch to the dish, making it not only gorgeous but appetizing as well.
