🔪 Tools You’ll Need in the Kitchen

Wok or large frying pan
Mixing bowls
Knife and cutting board
Chopsticks or tongs for tossing

Step 1: Prepare the Noodles

Bring a large pot of water to a boil. Add the glass noodles and cook according to package directions (usually 6-8 minutes) until they are translucent and chewy. Drain the noodles immediately and rinse them under cold water to stop the cooking process. Cut the noodles into shorter, manageable lengths (about 4-5 inches).

Step 2: Marinate the Beef (Optional)

In a small bowl, combine the thinly sliced beef with 1 tablespoon of soy sauce, 1/2 teaspoon of minced garlic, 1/4 teaspoon of black pepper, and 1 tablespoon of sesame oil. Mix well and set aside for at least 10 minutes.

Step 3: Prepare the Vegetables

Wash and julienne the carrot and red bell pepper. Thinly slice the onion and mushrooms. Wash the spinach thoroughly.

Step 4: Cook the Vegetables

Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Stir-fry the carrot until slightly tender, about 2-3 minutes. Remove from the pan and set aside. Add another teaspoon of oil and stir-fry the onion until translucent, about 2 minutes. Remove and set aside. Add another teaspoon of oil and stir-fry the mushrooms until browned and tender, about 3-4 minutes. Remove and set aside. Finally, add the spinach to the pan (no need for extra oil, as any residual moisture will help it wilt). Stir-fry until just wilted, about 1 minute. Remove and set aside.

Step 5: Cook the Beef (If Using)

Add 1 tablespoon of vegetable oil to the same skillet over medium-high heat. Add the marinated beef and stir-fry until cooked through and browned, about 3-5 minutes. Remove from the pan and set aside.

Step 6: Season the Noodles

In a large bowl, combine the cooked and drained noodles with 3 tablespoons of soy sauce, 2 tablespoons of sugar, 1 tablespoon of sesame oil, 1 tablespoon of rice vinegar, and 1 teaspoon of minced garlic. Toss well to ensure the noodles are evenly coated with the sauce.

Step 7: Combine Everything

Add the stir-fried vegetables (carrot, onion, mushrooms, red bell pepper, and spinach) and the cooked beef (if using) to the bowl with the seasoned noodles. Gently toss everything together until well combined.

Step 8: Serve

Transfer the japchae to a serving platter or individual bowls. Garnish with toasted sesame seeds. Serve warm or at room temperature
