How to Make Japchae (Korean Glass Noodle Stir Fry)
Step 1: Make the Japchae Sauce
In a mixing bowl, combine soy sauce, honey, brown sugar, and toasted sesame oil. Whisk until the sugar is dissolved.
Step 2: Cook the Japchae Noodles
Boil water in a large pot. Add the sweet potato glass noodles and cook for 10-15 minutes until tender. Stir occasionally to prevent sticking.
Step 3: Drain and Rinse Noodles
Once cooked, drain the noodles immediately. Rinse them with cold water until cool and set aside. Optionally, cut them into shorter pieces for easier eating.
Step 4: Make the Egg Crepe
Heat a small amount of oil in a nonstick pan over medium heat. Pour in beaten eggs, tilting to form a thin layer. Cook until set, then flip briefly. Remove from heat and let cool before cutting into thin strips.
Step 5: Cook the Beef
In the same pan over medium-high heat, add more oil if needed. Sear the beef strips lightly seasoned with salt and pepper for about 4-5 minutes until golden brown. Remove from pan and set aside.
Step 6: Sauté the Vegetables
Using the same pan on medium heat, add oil again if necessary. Start by sautéing carrots for about 30 seconds; then add onions followed by mushrooms, spinach, and green onion tops until all are tender.
Step 7: Assemble the Japchae
In the large pan or stir fry pan over medium heat, add your prepared japchae sauce. Stir occasionally until bubbling. Then reduce heat to low.
Step 8: Combine Everything Together
Add cooked noodles to the sauce and mix well until coated evenly. Include all other prepared ingredients—vegetables, beef, and egg strips—and toss gently to combine thoroughly.

- Control Heat When Sautéing: Adjust heat levels when cooking vegetables to avoid overcooking; they should remain crisp-tender.
- Mix Sauce Thoroughly: Make sure your sauce is mixed well before adding it to the noodles to ensure even flavor distribution.

Common Mistakes to Avoid
When making Japchae, it’s easy to make a few common mistakes that can impact the final dish. Here are some tips to ensure your stir fry turns out perfectly.
- Skipping the sauce preparation: Failing to mix the sauce ingredients before adding them can lead to uneven flavor. Always prepare and set aside the sauce first for a balanced taste.
- Overcooking the noodles: Boiling the sweet potato noodles for too long will make them mushy. Cook them just until they’re tender, usually about 10-15 minutes, then rinse immediately.
- Not seasoning vegetables properly: Neglecting to season your veggies while cooking can result in bland flavors. Lightly sprinkle salt and black pepper during sautéing for enhanced taste.
- Crowding the pan: Adding too many ingredients at once may cause steaming rather than frying. Work in batches if necessary to achieve that delicious stir-fried finish.
- Ignoring the order of cooking: Cooking harder vegetables first ensures everything cooks evenly. Start with carrots and onions before adding softer veggies like mushrooms and spinach.
- Inadequate cooling of egg crepe: If you don’t let the egg crepe cool enough before cutting, it will be difficult to handle. Allow it to cool until comfortable before slicing.
