Ingredients

Scale

Protein

  • 2 lb thin-sliced beef (or sub with chicken, tofu, or shrimp)

Noodles

  • 1 lb Korean sweet potato noodles (glass noodles)

Vegetables

  • 3 medium carrots, julienned
  • 1 large white onion, thinly sliced
  • 1/2 bunch green onions, chopped
  • 6 garlic cloves, minced
  • 1/2 lb spinach leaves

Oils and Sauces

  • 4 tbsp sesame oil (divided)
  • 1 tbsp olive oil
  • 6 tbsp soy sauce (or tamari for gluten-free)
  • 3 tbsp brown sugar

Instructions

  1. Prepare Noodles: Bring a large pot of water to a boil with a drizzle of olive oil. Add the sweet potato noodles and cook according to package instructions, about 5-6 minutes, until soft but chewy. Drain and set aside to prevent sticking.
  2. Cook Beef: Heat a skillet over high heat and add the thin-sliced beef. Cook until browned and nearly cooked through. While cooking, season with half of the soy sauce, sesame oil, and brown sugar to infuse flavor. Once cooked, remove and set aside.
  3. Sauté Vegetables: In another skillet, heat olive oil over medium-high heat. Add julienned carrots and sliced white onion; sauté until softened, about 4-5 minutes. Add the remaining soy sauce, sesame oil, and brown sugar for seasoning. Stir in minced garlic and chopped green onions, cooking for an additional minute until fragrant.
  4. Wilt Spinach: Add spinach leaves to the vegetable skillet and stir continuously until the leaves wilt and reduce in volume, about 1-2 minutes.
  5. Combine Ingredients: In a large mixing bowl, combine the cooked sweet potato noodles, sautéed vegetables including spinach, and the cooked beef. Toss thoroughly to evenly distribute the sauce and ingredients.
  6. Serve: Serve Japchae warm, garnished with extra chopped green onions if desired for added freshness and color.

Notes

  • Sweet potato noodles should not be overcooked to avoid them becoming too soft and breaking apart.
  • Variations can include substituting beef with chicken, tofu, or shrimp for different protein preferences.
  • For a gluten-free version, use tamari instead of regular soy sauce.
  • You can prepare vegetables ahead of time and cook them just before combining with noodles and protein.
  • Adjust sugar and soy sauce quantities to taste based on preferred sweetness and saltiness levels.
