Ingredients
To prepare this delicious Japchae (Korean Glass Noodle Stir Fry), gather the following ingredients:
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)
- 3 mushrooms (thinly sliced)
- 2 cups baby spinach (packed)
- 2 stalks green onion (cut into 1-inch pieces)
For Cooking and Seasoning
- Oil (for cooking)
- Toasted sesame seeds (optional for garnish)

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 until well combined. Set aside to let the flavors meld.
Step 2: Cook the Sweet Potato Noodles
In a large pot of boiling water, add the sweet potato glass noodles. Boil until cooked through, about 10-15 minutes. Stir occasionally to prevent sticking.
Step 3: Drain and Rinse Noodles
Once cooked, drain the noodles immediately. Rinse them thoroughly under cold water until completely cooled. Drain again and set aside. Optionally, use kitchen shears to cut into shorter pieces.
Step 4: Make the Egg Crepe
Heat a small amount of oil in a nonstick pan over medium heat. Pour in beaten eggs, tilting the pan to spread evenly. Cook until set on one side before flipping briefly. Remove from pan and cool before slicing into thin strips.
Step 5: Cook the Beef
In the same pan over medium-high heat, add some oil. Once hot, add beef strips seasoned with salt and pepper. Sear until golden brown, about 4-5 minutes. Remove from heat and set aside.
Step 6: Sauté Vegetables
Return to the same pan over medium heat with a bit of oil. Add vegetables according to their cooking time—carrots first, followed by onions, mushrooms, spinach, and green onion tops—seasoning lightly with salt and pepper as you go. Sauté until tender.
Step 7: Assemble the Japchae
In a large stir fry pan over medium heat, add prepared sauce to warm it slightly. Turn heat low after bubbling. Add cooked sweet potato noodles; mix well to coat evenly with sauce.
Step 8: Combine All Ingredients
Add remaining prepared ingredients including sautéed vegetables, beef strips, and egg crepe strips into the noodle mixture. Toss everything together until evenly combined.
Step 9: Serve Your Japchae
Portion out servings or serve family-style garnished with toasted sesame seeds if desired. Enjoy japchae hot, warm, room temperature or slightly chilled!

Japchae is a versatile dish that can be served in various ways, making it suitable for any occasion. Whether you’re hosting a party or enjoying a quiet meal at home, these serving suggestions will elevate your dining experience.
Family Style

With Pickled Vegetables

How to Perfect Japchae (Korean Glass Noodle Stir Fry)
Perfecting Japchae requires attention to detail in preparation and cooking methods. Here are some tips to help you achieve the best results:
- Use fresh ingredients: Fresh vegetables enhance the flavor and texture of your dish. Opt for seasonal produce when possible.
- Cook noodles al dente: To maintain the right texture, cook sweet potato glass noodles until they are just tender but still have a slight bite.
- Control heat levels: Sauté ingredients over medium heat to prevent burning while ensuring everything cooks evenly.
- Season layers: Season each component separately as you cook them. This builds flavor throughout the dish rather than relying solely on the sauce.
Best Side Dishes for Japchae (Korean Glass Noodle Stir Fry)
When serving Japchae, consider complementing it with side dishes that enhance its flavors and add variety to your meal. Here are some great options:
- Kimchi
A staple in Korean cuisine, kimchi offers spicy and tangy notes that balance out the sweetness of Japchae. - Korean Cucumber Salad
This refreshing salad made with cucumbers, vinegar, and sesame oil adds crunch and acidity. - Steamed Broccoli
Lightly steamed broccoli provides a nutritious side that pairs well with the noodles’ texture. - Korean Fried Tofu
Crispy fried tofu can add protein and texture. Serve it with soy sauce or chili paste for dipping. - Spicy Radish Salad
A zesty radish salad complements Japchae’s flavors while adding vibrant color to your meal. - Sesame Spinach Salad
Blanched spinach dressed with sesame oil offers another layer of flavor while being simple to prepare.
Common Mistakes to Avoid
When making Japchae, it’s easy to make a few common errors that can affect the dish’s flavor and texture. Here are some mistakes to watch out for.
- Skipping the noodle rinse: Failing to rinse the sweet potato glass noodles after boiling can lead to a gummy texture. Be sure to rinse them thoroughly under cold water until completely cooled.
- Overcooking vegetables: Cooking vegetables for too long can make them mushy. Sauté each type of vegetable just until tender to maintain their crunch.
- Not seasoning properly: Under-seasoning the dish can result in bland flavors. Taste and adjust the seasoning with salt, pepper, or additional soy sauce as needed.
- Skipping the egg crepe: Omitting the egg crepe can deprive your japchae of a beautiful texture and flavor contrast. Make sure to include it for an authentic experience.
- Using too much sauce: Adding excess sauce may overpower the ingredients. Start with a smaller amount and add more gradually while tossing until everything is well-coated.
- Neglecting ingredient prep: Not preparing ingredients ahead of time can lead to uneven cooking or overcooked components. Chop and organize all ingredients before starting to cook for an efficient process.
