Instructions
 

Step 1: Cook the Noodles

  • Boil a large pot of water and cook sweet potato noodles for 6–8 minutes until tender but chewy.
  • Drain, rinse under cold water, and toss with a little sesame oil. Set aside.

Step 2: Make the Sauce

  • In a bowl, whisk together soy sauce, sesame oil, brown sugar, minced garlic, and toasted sesame seeds.

Step 3: Prepare and Cook the Vegetables

  • Heat oil in a large pan over medium-high heat.
  • Stir-fry each vegetable group (carrots, peppers, onion, mushrooms, zucchini, scallions) individually for 1–2 minutes until just tender. Set aside.
  • Blanch the spinach briefly in boiling water (about 30 seconds), drain, and squeeze out excess water.

Step 4: Assemble the Japchae

  • In the same pan, add the cooked noodles and pour the sauce over.
  • Toss gently to coat the noodles.
  • Add all cooked vegetables and spinach.
  • Toss everything together carefully until well mixed and heated through.

Step 5: Garnish and Serve

  • Sprinkle extra sesame seeds over the japchae before serving. Enjoy warm, at room temperature, or cold!

Notes

  • Texture Tip: Cook vegetables separately to keep them crisp and colorful.
  • Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in a pan or enjoy cold.
  • Variations: Add tofu, tempeh, or chickpeas for extra protein. Mix in gochujang for a spicy twist!
  • Gluten-Free Option: Use tamari instead of soy sauce.
