Step‑by‑Step Instructions for Japchae (Korean Glass Noodle Stir Fry)
Step 1: Make the Sauce
In a mixing bowl, whisk together ¼ cup of soy sauce, 1 tablespoon of honey (or brown sugar), and 1 tablespoon of toasted sesame oil until fully combined. This sweet-savory sauce will enhance the flavor of the Japchae and should have a smooth consistency. Set it aside to let the flavors meld while you prepare the rest of the ingredients.
Step 2: Cook the Noodles
Bring a pot of water to a rolling boil, then add 8 ounces of sweet potato glass noodles. Boil for 10–15 minutes, or until the noodles are soft and slightly chewy. Once cooked, drain the noodles and rinse them under cold water to stop the cooking process and prevent stickiness. Set the noodles aside in a large bowl.
Step 3: Prepare the Egg
Heat a nonstick skillet over medium heat and add a small amount of oil. Beat 2 eggs in a bowl and pour them into the skillet, swirling to create a thin omelet. Cook for about 2-3 minutes, or until set, then carefully slide it onto a cutting board. Once cooled, julienne the omelet into thin strips and set them aside for later.
Step 4: Sear the Meat
In the same skillet, add a bit more oil and increase the heat to medium-high. Add 4 ounces of thinly sliced beef or pork, cooking for about 5-7 minutes, stirring frequently, until browned and cooked through. Check for doneness by ensuring there’s no pink remaining. Remove the meat from the pan and set it aside in a bowl.
Step 5: Cook the Vegetables
Using the same skillet, add 1 diced onion, 1 sliced carrot, and 4 ounces of mushrooms (shiitake or button works well). Sauté each vegetable for 2-3 minutes, until they soften but still retain some crunch. Season lightly with salt and pepper, then add 2 cups of baby spinach, cooking just until wilted. Once the vegetables are done, transfer them to a plate and keep warm.
Step 6: Combine Everything
Return the pan to medium heat and pour the prepared sauce into it, allowing it to heat for about 1 minute. Add the cooked noodles, tossing them in the sauce until they are evenly coated and glossy. Incorporate the sautéed vegetables, seared meat, and strips of omelet, gently mixing everything together for about 2-3 minutes, allowing the flavors to meld beautifully.
Step 7: Serve
Transfer the Japchae to a serving dish, garnishing with sesame seeds and sliced green onions if desired. Serve this vibrant Korean glass noodle stir fry hot or warm, perfect as a main dish or alongside your favorite sides. Enjoy the delightful flavors and beautiful presentation of your homemade Japchae!

Japchae (Korean Glass Noodle Stir Fry) Recipe FAQs
How do I choose the best sweet potato glass noodles?
Absolutely! When selecting sweet potato glass noodles, look for packages that specifically state “sweet potato starch” on the label. These noodles should be translucent and slightly chewy in texture. Avoid any that appear overly brittle or have dark spots all over the package, as these could indicate poor quality.
How should I store leftover Japchae?
To maintain freshness, keep your leftover Japchae in an airtight container in the fridge. It can stay good for up to 3 days. Make sure to allow the dish to cool completely before sealing to prevent condensation, which can make the noodles mushy.
Can I freeze Japchae for later?
Yes, you can freeze Japchae! To do this, place portioned servings into airtight containers or freezer bags, ensuring you remove as much air as possible. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the fridge before reheating on the stovetop with a splash of water to keep it from drying out.
What if my noodles become sticky after cooking?
Very! If your noodles become sticky, it’s likely due to not rinsing them properly post-cooking. After boiling, make sure to drain them and rinse under cold water thoroughly for about 1-2 minutes until they cool down. This will stop them from continuing to cook and get that wonderful chewy texture we all love.
Is Japchae safe for those with gluten allergies?
Certainly! Japchae can be gluten-free as long as you use sweet potato glass noodles and gluten-free soy sauce or tamari. Double-check all your ingredients, especially sauces and seasonings, to ensure they don’t contain any gluten, keeping your dish safe for those with allergies.
What are some great protein alternatives for a vegetarian or vegan version?
For a delicious vegetarian or vegan Japchae, tofu is an excellent substitute! You can use extra-firm tofu, pressing it to remove excess moisture, then pan-fry it until golden. Alternatively, feel free to incorporate other plant-based proteins such as tempeh or edamame, which will add both flavor and texture to your dish!
