How to Make Japchae (Korean Sweet Potato Glass Noodle Stir-Fry) Recipe
Step 1: Marinate the Beef
Start by thinly slicing your ribeye or sirloin, then marinate it with 1 tablespoon soy sauce, 1 teaspoon sugar, 1 teaspoon sesame oil, and half of your minced garlic. This tenderizes the beef and infuses it with flavor, setting up a savory base that will shine through the stir-fry.
Step 2: Prepare the Vegetables and Mushrooms
If your shiitake mushrooms are dried, soak them in warm water until they’re plump and soft, then slice them thinly. Next, julienne the carrot, slice the onion, red bell pepper, and green onions. Taking care with your knife skills here ensures that the vegetables cook evenly and present beautifully in the final dish.
Step 3: Cook the Sweet Potato Noodles
Bring a pot of water to a boil and cook the sweet potato noodles for 6 to 7 minutes until tender but still chewy. Then, drain them and rinse under cold water to stop the cooking process and prevent sticking. Toss the noodles with 1 teaspoon of sesame oil to keep them glossy and separate.
Step 4: Sauté Vegetables Separately
In a pan with a little oil, sauté each vegetable separately to preserve its texture and color. Cook carrots for 2 to 3 minutes first, then remove; repeat this with onions, red bell peppers, mushrooms, and finally the spinach. Cooking each separately ensures that no veggie becomes mushy or overcooked, and the final dish bursts with contrasting textures.
Step 5: Cook the Marinated Beef
Using the same pan, cook the marinated beef over medium-high heat until it is fully browned. The pan’s residual oils and bits from the vegetables create a flavorful foundation, and the beef will be tender and savory thanks to the careful marinating.
Step 6: Combine Everything
In a large bowl, place the cooked noodles and pour in the remaining soy sauce, sugar, and sesame oil. Add all your sautéed vegetables and cooked beef to the noodles. Gently toss everything together using tongs or chopsticks, making sure each noodle is coated evenly with the seasoned sauce and ingredients, uniting all those delicious flavors.
Step 7: Garnish and Serve
Finally, sprinkle toasted sesame seeds and sliced green onions on top for a beautiful finishing touch. This dish can be enjoyed warm or at room temperature, making it wonderfully versatile for any occasion.

Side Dishes
This Japchae (Korean Sweet Potato Glass Noodle Stir-Fry) Recipe pairs beautifully with Korean staples like kimchi or a simple bowl of steamed rice. The mild, chewy noodles and savory meat balance well against the spicy, tangy notes of fermented vegetables, making your meal harmoniously satisfying.
Creative Ways to Present
For a festive occasion, consider serving Japchae in individual lettuce cups for a hand-held delight or topping it with a fried egg to add richness. Alternatively, arranging the colorful veggies and beef artistically over the noodles on a large platter creates a stunning centerpiece.
Make Ahead and Storage
Storing Leftovers
Japchae keeps well refrigerated in an airtight container for 2 to 3 days. The noodles soak up the sauce over time, intensifying flavors and softening textures slightly, so it actually tastes great as leftovers.
Freezing
While freezing is possible, it is not ideal for Japchae because the texture of the noodles and vegetables can change and become mushy when thawed. If you do freeze, use airtight containers and consume within 1 month for best quality.
Reheating
To reheat, gently warm Japchae in a pan over low-medium heat with a splash of water or oil to prevent sticking and to loosen the noodles. Avoid microwaving for too long as it can dry out the dish.
FAQs
Can I make Japchae vegetarian?
Absolutely! Simply omit the beef and add extra mushrooms, tofu, or additional vegetables like zucchini or broccoli for protein and texture. Adjust the soy sauce and seasoning to your preference for a satisfying vegetarian version.
What kind of noodles are best for Japchae?
The dish traditionally uses sweet potato glass noodles, known as dangmyeon. Their chewy texture and transparent appearance are essential for authentic Japchae.
Can I prepare Japchae ahead of time for a party?
Yes! Japchae tastes great at room temperature, making it perfect for potlucks and gatherings. You can prepare it the day before and refrigerate it, just gently rewarm or serve as is.
Is Japchae a healthy dish?
Japchae is relatively healthy since it uses nutrient-rich vegetables, lean beef, and heart-healthy sesame oil. However, the sodium content in soy sauce is something to watch if you’re on a low-sodium diet.
Why do I need to cook the vegetables separately?
Cooking each vegetable separately ensures ideal texture and color retention. If cooked together, some vegetables may become overcooked or soggy while others remain underdone, compromising the dish’s balance.
