Step‑by‑Step Instructions for Japchae – Korean noodles

Step 1: Marinate the Beef
In a medium bowl, combine soy sauce, sugar, minced garlic, and black pepper to create the marinade. Add thinly sliced beef short ribs, ensuring they are well coated. Let the beef marinate for 15-20 minutes at room temperature, allowing the flavors to infuse and tenderize the meat.

Step 2: Cook the Noodles
Boil a pot of water and add the sweet potato noodles (dangmyeon). Cook them according to the package instructions, usually around 6-8 minutes, or until they feel tender yet slightly chewy. Drain and rinse the noodles under cold water to stop the cooking process; set them aside in a large mixing bowl.

Step 3: Prepare the Dressing
In a small bowl, whisk together soy sauce, sugar, minced garlic, sesame oil, salt, and pepper to create the dressing. This mixture will add a rich depth of flavor to your Japchae. Set it aside, as you will mix it into the noodles and vegetables later.

Step 4: Sauté the Aromatics
Using a large skillet or wok, heat vegetable oil over medium-high heat. Add sliced onions, shiitake mushrooms, and the white parts of green onions. Stir-fry for about 4-5 minutes until the onions become translucent and the mushrooms soften; then, transfer the cooked mixture to the bowl with noodles.

Step 5: Cook the Vegetables
In the same skillet, add a bit more vegetable oil if needed, and toss in the carrots and bell peppers. Stir-fry for about 3-4 minutes until they’re slightly tender and vibrant in color. Add the baby spinach last, cooking until just wilted, about 1-2 minutes; transfer this colorful mix to the noodle bowl.

Step 6: Cook the Beef
Increase the heat to high, adding a bit more vegetable oil if required. Add the marinated beef to the hot skillet and cook for about 5-7 minutes until it’s browned and cooked through. Look for a nice sear on the beef for added flavor, then transfer it to the bowl with the other ingredients.

Step 7: Combine All Ingredients
Gently toss the noodles, sautéed vegetables, and beef in the mixing bowl with the dressing. Use two pairs of chopsticks or tongs to combine everything evenly, ensuring every strand of noodle is coated in that delicious dressing. This is the moment your Japchae truly comes together!

Step 8: Garnish and Serve
Finally, plate your beautifully mixed Japchae and garnish it with a sprinkle of toasted sesame seeds for added texture and visual appeal. Serve warm as a delightful main dish or as an accompaniment to grilled proteins. Enjoy the vibrant flavors of your homemade Japchae – Korean noodles!

How to Store and Freeze Japchae

Fridge: Store leftover Japchae in an airtight container in the refrigerator for up to 3 days. Enjoy it cold or gently reheated on the stovetop to maintain the noodle’s chewy texture.

Freezer: For longer storage, freeze portions of Japchae in freezer-safe containers for up to 2 months. Thaw in the refrigerator overnight before reheating.

Japchae (Korean Glass Noodles) Recipe FAQs

What type of beef should I use for Japchae?

How should I store leftover Japchae?
Very simple! Store your leftover Japchae in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, you can eat it cold or gently reheat it on the stovetop for a delicious meal! Just add a splash of water to maintain the moisture.

Yes, you can! To freeze, portion out the Japchae into freezer-safe containers, ensuring to leave some space for expansion. It can be kept frozen for up to 2 months. When you’re ready to eat, simply thaw it in the refrigerator overnight before reheating on the stovetop to enjoy!

What should I do if my sweet potato noodles are too sticky?
Don’t worry, it happens! If your sweet potato noodles stick together, try rinsing them under cold water after cooking to prevent sticking. Ensure they are slightly chewy when cooked, and mixing in a bit of cooking oil before serving can also help separate them.

Are there any dietary considerations with Japchae?
Certainly! If you’re concerned about gluten, you can substitute the soy sauce with gluten-free soy or tamari. Additionally, for a vegetarian option, swap out the beef for tofu and load up on your favorite vegetables. It’s a versatile recipe that can accommodate many dietary needs!

How long do the ingredients stay fresh?
In terms of freshness, vegetables like bell peppers and carrots should ideally be used within a week of purchase for the best crispness.

Cooked Japchae, as mentioned, can last in the fridge for 3 days without losing its wonderful flavors!
