Ingredients

Scale

Potato Noodles

  • 2 medium russet potatoes (about 420g)
  • 1 ⅓ cup potato starch (about 200g)
  • ½ cup water (adjust as needed)
  • 1 green onion, chopped (for garnish)

Chili Oil

  • 2 tbsp soy sauce
  • 1 tbsp black vinegar
  • ½ tbsp Chinese chili flakes
  • ½ tsp chili powder (gochugaru)
  • 3 cloves garlic, minced
  • 1 green onion, chopped
  • 2 tbsp hot neutral oil (such as avocado, canola, vegetable, grapeseed, or peanut oil)

Instructions

  1. Prepare Potato Noodles Dough: Peel and grate the russet potatoes. Squeeze out excess moisture, then mix the grated potatoes with potato starch and water until a dough forms. Adjust water or starch as needed to reach a firm but pliable consistency.
  2. Form Noodles: Roll the dough into a thin sheet, then cut into thin noodle strips using a knife or pasta cutter.
  3. Cook Noodles: Bring a large pot of water to a boil. Add the potato noodles and cook for about 3-5 minutes or until they float and reach a chewy texture. Drain and rinse briefly under cold water to stop cooking, then set aside.
  4. Make Chili Oil: Heat the neutral oil in a small pan over medium heat. Add the minced garlic and chopped green onion and fry until fragrant but not burnt. Remove from heat and immediately add soy sauce, black vinegar, Chinese chili flakes, and chili powder. Stir to combine, forming a vibrant chili oil sauce.
  5. Toss Noodles: Place the cooked noodles in a bowl, pour the prepared chili oil over them, and toss thoroughly to coat all noodles evenly with the sauce.
  6. Garnish and Serve: Sprinkle chopped green onion over the noodles for a fresh bite. Serve immediately and enjoy the spicy, tangy flavors and unique potato noodle texture.

Notes

  • Adjust water amount while mixing dough to ensure the right noodle texture — it should not be too sticky or too dry.
  • Use fresh potatoes for the best texture; avoid pre-packaged shredded potatoes as they may have preservatives.
  • Feel free to adjust chili levels to your taste by adding or reducing chili flakes and chili powder.
  • Ensure the oil is hot before pouring over the chili mixture to release the flavors.
  • This dish is best served fresh, as the noodles can become gummy if left to sit too long.
