Step‑by‑Step Instructions for Japchae
Step 1: Prepare Japchae Sauce
In a mixing bowl, whisk together 7 tablespoons of soy sauce, 3 tablespoons of honey or 2 tablespoons of brown sugar, and 2 tablespoons of toasted sesame oil. Ensure the ingredients are well combined, creating a savory and slightly sweet sauce that will coat the delicious elements of your Japchae. Set this mixture aside for later use.
Step 2: Cook Noodles
Bring a large pot of water to a rolling boil and add the sweet potato glass noodles. Cook them for 10–15 minutes until they are tender and chewy, stirring occasionally to prevent sticking. Once cooked, drain the noodles and rinse them under cold water to stop the cooking process and maintain their bouncy texture.
Step 3: Make Egg Crepe
In a non-stick skillet, heat a teaspoon of cooking oil over medium heat. Pour in 2 beaten eggs, swirling the pan to create an even layer. Cook until the egg is set and lightly golden on both sides, about 2-3 minutes per side. Remove from the pan and slice the egg crepe into thin strips to add a delightful richness to your Japchae.
Step 4: Sear Meat
In the same skillet, add a splash of oil if necessary and increase the heat to medium-high. Sear 16 ounces of thinly sliced beef or pork for about 3-4 minutes, seasoning with salt and pepper while cooking. Once the meat is browned and cooked through, remove it from the pan and set aside, allowing the flavors to mingle later on.
Step 5: Cook Vegetables
Lower the heat slightly and add a bit more oil to the skillet. Start with the onions and cook them for 2-3 minutes until they become translucent. Next, add the julienned carrot and mushrooms, sautéing for another 3-4 minutes until the vegetables are tender yet still vibrant. Finally, toss in 2 cups of baby spinach, and cook just until wilted, about 1 minute.
Step 6: Assemble Japchae
Return the cooked noodles to the skillet with the sautéed vegetables. Pour the prepared sauce over the mixture and add the seared meat and sliced egg crepe. Toss everything together gently for about 2-3 minutes, allowing the noodles and ingredients to absorb the flavors, creating a beautifully mixed Japchae.
Step 7: Serve
Transfer the vibrant Japchae to a serving platter, garnishing with toasted sesame seeds for added texture and flavor. This dish can be enjoyed warm or at room temperature, making it a versatile and inviting option for any meal, whether a cozy family dinner or a festive gathering.

Make Ahead Options
Japchae is an ideal dish for meal prep, allowing you to savor its delicious flavors without the last-minute rush! You can prepare the sweet potato glass noodles and sautéed vegetables up to 24 hours in advance. Simply cook and then refrigerate the noodles, and keep the sautéed veggies in a separate container to maintain their crispiness. When you’re ready to serve, stir-fry the prepped components, add your protein (meat or tofu), and pour in your prepared sauce. This way, you’ll have a delightful, homemade Japchae ready in just minutes, making dinner on busy nights a breeze!
