Ingredient Notes

Korean Glass Noodles

Korean glass noodles, called dangmyeon, are made from sweet potato starch.

They become chewy, glossy, and slightly transparent after cooking. These noodles are the most important ingredient in Japchae.

Pork

Thinly sliced pork for japchae adds savory flavor and makes the dish more satisfying.

You can also use beef, chicken, or skip the meat for a vegetable japchae version.

Wood Ear Mushrooms

Wood ear mushrooms add a chewy texture that works well with the glass noodles.

Soak them in water before using.

Vegetables

Carrot, onion, bell pepper, and garlic chives add color, sweetness, and freshness.

You can adjust the vegetables depending on what you have.

Soy Sauce and Syrup Ratio

This recipe uses a 1:2 ratio of soy sauce to syrup.

For example, 10 tablespoons of soy sauce and 20 tablespoons of syrup.

If you prefer a less sweet Japchae, reduce the syrup slightly.

If using oligosaccharide syrup instead of corn syrup, use a little less because it can taste sweeter.

How to Make Japchae

Step 1: Soak the Wood Ear Mushrooms

Place the wood ear mushrooms in a bowl of water.

Let them soak until softened.

Once softened, rinse them and cut into bite-sized pieces if needed.

Step 2: Marinate the Pork

Place the pork in a bowl.

Add:

• 1 tsp minced garlic
• 1 tsp soy sauce
• 1 tsp sesame oil
• 2 tsp mirim or cooking wine
• A pinch of black pepper

Mix well and let it marinate for about 20 minutes.

This gives the pork better flavor and helps reduce any meat odor.

Step 3: Prepare the Vegetables

Slice the carrot, bell pepper, onion, and garlic chives into thin, bite-sized pieces.

Keep the vegetables similar in size so they cook evenly.

You can use any vegetables you like, but colorful vegetables make Japchae look much better.

Step 4: Cook the Glass Noodles

Bring a large pot of water to a boil.

Add the glass noodles and boil for about 11 minutes.

This is one of the key points for making delicious Japchae.

The noodles should become soft and chewy, but not mushy.

Step 5: Stir-Fry the Vegetables and Pork

While the noodles are boiling, stir-fry the vegetables and pork separately.

Cook the vegetables briefly so they stay slightly crisp.

Cook the pork until fully done.

Set everything aside.

Do not stir-fry the garlic chives for too long. They taste best when they stay fresh and slightly firm.

Step 6: Rinse the Noodles

After 11 minutes, drain the noodles immediately.

Rinse them under cold water.

Drain well.

This helps stop the cooking process and keeps the noodles chewy.

Step 7: Make the Japchae Sauce

In a large pan or wok, add:

• 10 tbsp soy sauce
• 20 tbsp corn syrup or Korean cooking syrup

Bring the sauce to a boil.

Once it starts bubbling, add the drained glass noodles.

Step 8: Coat the Noodles with Sauce

Add about 4 tablespoons of canola oil or neutral cooking oil.

Stir-fry the noodles over high heat while mixing continuously.

Cook until the sauce reduces and the noodles become glossy and evenly coated.

The oil helps prevent the noodles from sticking together and keeps them from becoming too soft.

Step 9: Cool the Noodles Slightly

Transfer the seasoned noodles to a large mixing bowl.

Let them cool slightly before adding the vegetables and pork.

This makes it easier to mix everything evenly.

Step 10: Mix Everything Together

Add the stir-fried vegetables, mushrooms, pork, and garlic chives to the seasoned noodles.

Mix everything gently until evenly combined.

Taste and adjust if needed.

If it tastes too light, add a little more soy sauce.

If you prefer it sweeter, add a little more syrup.

Step 11: Serve

Transfer the Japchae to a serving plate.

Serve warm, at room temperature, or chilled.

Japchae tastes delicious in all three ways.

Pro Tips

Boil the Noodles for 11 Minutes

The texture of the noodles is very important.

Boiling the noodles for about 11 minutes gives them a soft but chewy texture that works well for Japchae.

Use the 1:2 Sauce Ratio

The basic sauce ratio is soy sauce to syrup at 1:2.

This creates the classic sweet and savory Japchae flavor.

Adjust the sweetness depending on your taste.

Stir-Fry the Noodles in the Sauce

Instead of simply mixing boiled noodles with sauce, cook the noodles directly in the sauce.

This helps the noodles absorb flavor and gives them a beautiful glossy color.

Add Oil to Prevent Sticking

Adding neutral oil while coating the noodles helps prevent them from sticking together.

It also helps the noodles stay smooth and glossy.

Do Not Overcook the Vegetables

Japchae tastes better when the vegetables still have some texture.

Stir-fry them briefly instead of cooking them until too soft.

Mix After Cooling Slightly

If the noodles are too hot, the vegetables can become overcooked while mixing.

Let the noodles cool slightly before combining everything.

What to Serve with Japchae

Japchae pairs well with:

• Kimchi
• Bulgogi
• Galbi
• Korean fried chicken
• Steamed rice
• Korean rolled omelet
• Cucumber salad
• Bean sprout side dish
• Pan-fried tofu

Japchae can be served as a side dish, party dish, lunch box dish, or light main meal.

Storage Tips

Store leftover Japchae in an airtight container in the refrigerator.

It will keep well for up to 3 days.

To reheat, stir-fry it briefly in a pan over medium heat.

You can also microwave it, but pan reheating gives a better texture.

If the noodles become dry, add a small splash of water or a few drops of sesame oil while reheating.
