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. Set aside to allow the flavors to meld.
Step 2: Cook the Japchae Noodles
In a large pot of boiling water, add the sweet potato noodles. Boil until cooked through, about 10-15 minutes. Stir occasionally to prevent sticking. Drain immediately and rinse thoroughly with cold water until completely cooled. Optionally cut noodles into shorter lengths with kitchen shears for easier eating.
Step 3: Make the Egg Crepe
In a nonstick pan over medium heat, add a small amount of oil. When hot, pour in beaten eggs. Tilt to spread evenly into a thin layer. Cook until set on one side then flip briefly. Remove from pan and cool before cutting into thin strips.
Step 4: Cook the Beef
Using the same pan over medium-high heat, add oil again. Once hot, add beef strips seasoned with salt and pepper. Sear until golden brown and cooked through, about 4-5 minutes. Remove from pan and set aside.
Step 5: Sauté Vegetables
In the same pan over medium heat, add oil again. Sauté vegetables according to their heartiness—start with carrots followed by onions, green onion bottoms, mushrooms, spinach, and finally green onion tops. Season lightly with salt and black pepper as you cook each batch until tender. Remove from pan once done.
Step 6: Assemble Japchae
Return to your stir-fry pan over medium heat with prepared sauce. Stir occasionally until sugar dissolves and sauce bubbles lightly; reduce heat to low. Add cooked noodles first then combine with sautéed vegetables, beef strips, and egg crepe strips. Toss everything together until well mixed.
Step 7: Serve
Portion out servings or serve family-style with a sprinkle of toasted sesame seeds on top. Enjoy Japchae warm or at room temperature!
