How to Make Spicy Potato Noodles

Step 1 – Cook the Potatoes

Boil the potato pieces in salted water until fork-tender, about 10 to 15 minutes. Drain well and place in a large mixing bowl.

Step 2 – Make the Dough

While the potatoes are still hot, mash them until smooth. Add the salt, sprinkle in the potato starch, and knead until it starts to form a dough. Gradually pour in the warm water and knead again until soft and cohesive.

Step 3 – Shape the Noodles

Divide the dough into 14 pieces. Roll each into long ropes about ½ inch thick. Keep the rest covered with a damp towel so they don’t dry out.

Step 4 – Cook the Noodles

Bring a large pot of water to a boil. Drop in the potato noodles one at a time, stirring gently so they don’t stick. Once they float, cook for one more minute, then transfer to a bowl of cool water.

Step 5 – Make the Chili Oil

In a heatproof bowl, combine soy sauce, black vinegar, gochugaru, sugar, salt, garlic, and green onion. Heat the oil until smoking, then carefully pour it over the mixture. Stir well — it should sizzle and release that deep, spicy aroma.

Step 6 – Toss and Serve

Drain the noodles and place them in a clean bowl. Pour over the chili oil sauce, toss until evenly coated, and finish with chopped cilantro. Serve warm and enjoy every bite.

Tips for Perfect Potato Noodles

  • Work the dough while warm to keep it stretchy and pliable.
  • Cover resting dough with a damp towel to prevent cracks.
  • If the dough cools too much, microwave it for 15 seconds to soften.
  • Don’t crowd the pot — noodles need space to move freely.

Storage & Reheating

These noodles are best fresh but can be stored in an airtight container for up to 3 days. Reheat in the microwave or a skillet with a splash of water to revive the chewy texture.

FAQ

Can I use cornstarch instead of potato starch?

Not quite cornstarch won’t create the same chewy bounce. Potato starch gives that signature texture.

What if I can’t find black vinegar?

Rice vinegar works in a pinch. It’s sharper, so use a little less for balance.

Can I make the chili oil ahead?

Yes! Store homemade chili oil in a sealed jar in the fridge for up to 3 months. It’s amazing on dumplings or even fried eggs.

Serving Ideas
