Ingredients you’ll need
- Korean glass noodles – also known as dangmyeon, sweet potato starch noodles, or japchae noodles. These noodles are slightly chewy and turn translucent when cooked. A must have for making this recipe.
- Shiitake mushrooms – it gives this vegetarian dish a meaty flavor
- Colorful vegetables – red and yellow bell pepper, carrots, spinach
- Soy sauce – a must have for the japchae sauce
- Brown sugar – adds the perfect amount of sweetness
- Dark soy sauce – gives it a deeper color that contrasts beautifully with the colorful veggies
Step by step instructions
- First mix the japchae sauce together in a small bowl and set it aside.
- Boil the Korean glass noodles according to the directions. Be careful not to overcook them. Drain the water and add the sauce to the hot noodles. All the sauce will get absorbed by the noodles after several minutes.
- Cook the egg whites and egg yolks separately in a flat plan. Cut them into strips and set it aside.
- Heat a pan over medium high heat and start stir frying the mushrooms and onions together. Next add the garlic, carrots, and peppers and stir fry for 1 to 2 minutes.
- Be careful not to overcook the vegetables. They should still have a bit of crunch.
- Finally, add the baby spinach and toss it together until they wilt.
- By now, the noodles should have absorbed all of the japchae sauce and should be a rich, deep color.
- Add the stir fried vegetables to the glass noodles and toss them to combine. Garnish with sesame seeds and scallions.
- Serve immediately or store it in an airtight container and keep it in the fridge for up to 3 days.
Expert tips & tricks
- Don’t overcook the glass noodles – the noodles should have a chewy, al dente texture. Overcooking the noodles also prevents it from absorbing all of the japchae sauce so keep an eye on the timer.
- Don’t overcook the vegetables – the vegetables should be crisp and crunchy to contrast with the chewy texture of the noodles. Add the vegetables in at different times according to their cook time. Vegetables that take longer should be added first while the ones that take shorter (like spinach) should be added last.
- Add the sauce while the noodles are hot – this helps the noodles absorb all the sauce and prevents them from sticking together. I prefer not to rinse the noodles as it makes them too watery for me and they absorb flavors better when they’re hot.
Ingredient substitutions & variations
- Other vegetables – broccoli, zucchini, green beans, sugar snap peas, cabbage
- Other vegetarian proteins – fried tofu, edamame, tempeh
- Non-vegetarian proteins – pork, chicken, beef
- Make it spicy – add a tablespoon of Korean red pepper flakes (gochugaru) to the sauce
Storing & reheating leftovers
- Store leftovers in an airtight container and keep it in the fridge for up to 3 days.
- You can make this ahead the day before and serve it the next day.
- The noodles will harden and turn opaque when cold.
- Reheat it in the microwave until the noodles get soft and turn translucent.
