How to Make Japchae (Korean Glass Noodle Stir Fry)
Step 1: Prepare the Japchae Sauce
Mix together all the sauce ingredients in a bowl until combined. Set aside for later use.
Step 2: Cook the Sweet Potato Noodles
In a large pot of boiling water, add the sweet potato glass noodles. Boil for about 10-15 minutes until cooked through. Stir occasionally to prevent sticking.
Step 3: Rinse Noodles
Once cooked, drain the noodles immediately. Rinse thoroughly with cold water until cooled completely. Drain well again and set aside. You may cut them into shorter pieces with kitchen shears if desired.
Step 4: Make the Egg Crepe
Heat a small amount of oil in a nonstick pan over medium heat. Pour in the beaten eggs and tilt to spread evenly. Cook until set on one side, flip, then cook briefly on the other side. Remove from pan once cooked and cool before slicing into thin strips.
Step 5: Cook the Beef
In the same pan over medium-high heat, add more oil if needed. Add sliced beef, season lightly with salt and pepper, then sear until golden brown—about 4-5 minutes. Remove from pan and set aside.
Step 6: Sauté Vegetables
Using the same pan over medium heat, add oil again if necessary. Start by sautéing carrots first for about 15 seconds before adding onions and green onion bottoms. Follow with mushrooms, spinach, then top with green onion tops—cooking just until tender.
Step 7: Assemble Japchae
In either a large pan or mixing bowl over medium heat, add your prepared japchae sauce. Stir occasionally until it bubbles slightly. Turn down to low heat.
Step 8: Combine Ingredients
Add cooked sweet potato noodles to your sauce mixture; stir to coat evenly. Then incorporate all prepared ingredients—vegetables, beef strips, and egg strips—tossing everything together gently.
Step 9: Serve
Serve portions of japchae hot or at room temperature garnished with toasted sesame seeds if desired. Enjoy this flavorful dish alone or paired with other meals!
