For the Noodles and Protein
- 12 ounces sweet potato glass noodles
- 16 ounces beef (cut into strips)
For the Vegetables
- 2 large eggs (beaten)
- 1 large carrot (peeled and julienned)
- 1 medium yellow onion (thinly sliced)

- 2 cups baby spinach (packed)
- 2 stalks green onion (cut into 1 inch pieces)
For Cooking
- Oil (for cooking)
- Salt and black pepper (as needed)
For the Sauce
- 7 tablespoons soy sauce (light sodium)
- 3 tablespoons honey (or more brown sugar)
- 2 tablespoons brown sugar (light or dark)
- 2 tablespoons toasted sesame oil
How to Make Japchae (Korean Glass Noodle Stir Fry)
Step 1: Make the Japchae Sauce
Mix together all the ingredients for the sauce in a bowl and set aside.
Step 2: Cook the Japchae Noodles
In a large pot of boiling water, add the sweet potato glass noodles. Boil until cooked through, about 10-15 minutes depending on brand. Stir occasionally to prevent sticking. Once done, drain immediately and rinse with cold water until completely cooled. Drain well again.
Step 3: Make the Egg Crepe
In a nonstick pan over medium heat, add a small amount of oil. Pour in the beaten eggs when hot, tilting to spread them into a thin layer. Cook until set, then flip briefly. Remove from heat and let cool before cutting into thin strips.
Step 4: Cook the Beef
In the same pan over medium-high heat, add a little oil. When hot, add beef strips seasoned with salt and pepper. Sear until golden brown, about 4-5 minutes. Remove from pan.
Step 5: Sauté the Vegetables
Using the same pan on medium heat, add more oil if needed. Sauté each vegetable according to their heartiness:
1. Add carrots first; sauté for 15-30 seconds.
2. Next, add onions and green onion bottoms.
3. Follow with mushrooms, then spinach last.
Season lightly with salt and pepper between additions.
Step 6: Assemble the Japchae
Add prepared sauce to the same large pan over medium heat. Stir until sugar dissolves and sauce bubbles slightly; turn down heat. Mix in japchae noodles until evenly coated, then fold in vegetables, beef, and egg strips until combined.
Step 7: Serve
Portion out your japchae or serve family-style garnished with sesame seeds as desired. Enjoy hot, warm, at room temperature, or slightly chilled!

Common Mistakes to Avoid
When making Japchae, it’s important to avoid common pitfalls that can affect the dish’s flavor and texture. Here are some mistakes to watch out for:

- Overcooking the vegetables: Overcooked veggies lose their crunch and flavor. Sauté them until just tender to maintain their taste and texture.
- Ignoring sauce balance: Using too much soy sauce or sugar can overpower the dish. Adjust your sauce ingredients to achieve a balanced flavor.
