How to Make Japchae (Korean Glass Noodle Stir Fry)
Step 1: Make the Japchae Sauce
Mix together all ingredients for the sauce in a small bowl. Set aside.
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. Drain immediately and rinse under cold water until completely cooled. Set aside.
Step 3: Prepare the Egg Crepe
In a nonstick pan over medium heat, add oil. Once hot, pour in beaten eggs. Tilt the pan to spread eggs into a thin layer. Cook until set on one side, then flip briefly to cook other side. Remove from heat and let cool before cutting into strips.
Step 4: Sear the Beef
In the same pan over medium-high heat, add oil. When 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 the Vegetables
In the same pan over medium heat, add oil again. Start with carrots; sauté for 15-30 seconds before adding onions and green onion bottoms. Follow with mushrooms, spinach, then green onion tops until tender.
Step 6: Assemble Japchae
In a large pan or stir fry pan over medium heat, combine prepared japchae sauce until bubbling slightly. Add cooked noodles; mix until coated evenly. Then add all prepared ingredients—vegetables, beef strips, and egg strips—tossing gently to combine evenly.
Step 7: Serve
Portion out japchae onto plates or serve family style with a sprinkle of sesame seeds on top. Enjoy hot, warm, at room temperature, or slightly chilled!
