👨‍🍳 How to Make

1. Cook the Noodles
Boil noodles according to package instructions (about 6–7 minutes). Drain and rinse under cold water. Cut with scissors into 6–8 inch lengths for easier eating. Toss with 1 teaspoon sesame oil to prevent sticking

2. Marinate the Beef
Mix sliced beef with ½ tablespoon soy sauce, ½ teaspoon sugar, ½ teaspoon sesame oil, and minced garlic. Let marinate while prepping veggies

3. Sauté the Vegetables
In a lightly oiled pan, sauté onions, carrots, bell peppers, and mushrooms separately over medium-high heat for 2–3 minutes each, seasoning lightly with a pinch of salt. Set aside.

Blanch spinach in boiling water for 30 seconds, rinse under cold water, squeeze out excess water, and set aside

4. Cook the Beef
In the same pan, cook marinated beef over medium-high heat until just cooked through. Set aside

5. Combine Everything
In a large mixing bowl or wok, combine noodles, beef, and vegetables
Add the japchae sauce (soy sauce, sugar, sesame oil, garlic, sesame seeds)
Toss well over medium heat or warm in a large skillet, stirring gently until fully combined and heated through

6. Garnish & Serve
Top with thin strips of egg (if using), extra sesame seeds, and chopped green onions
Serve warm, at room temperature, or chilled

🥕 Mix-ins & Garnishes

Julienned cucumber or daikon for crunch
Chili flakes or gochugaru for spice
Toasted nori strips
Toasted cashews or pine nuts for texture

✅ Recipe Tips

Slice all vegetables uniformly for even cooking and a beautiful presentation

Japchae tastes even better the next day after the flavors meld
