Spicy Potato Noodles in Chili Oil Sauce – 50-Minute Comfort

There is a particular kind of quiet in a kitchen when a dough rests under a bowl. The light comes in low, the flour settles, and you wait. These spicy potato noodles begin there, with potatoes and starch and a little patience.

The noodles are soft, almost translucent, and they drink up the chili oil like paper taking ink. Garlic, sesame, and vinegar meet them in the bowl, and the whole thing glows a deep amber.

I make this on evenings when the day has been too loud. The rolling is slow work. The reward is immediate. Less, but better.

About the Ingredients

1 lb (450 g) russet potatoes, peeled and cut into 1-inch chunks

Russets bring the fluffiest, driest mash, which makes the dough easier to handle. Yukon Golds work too, but add 2 tablespoons more potato starch since they hold more moisture.

1 1/2 cups (180 g) potato starch, plus more for dusting

Potato starch, not potato flour, gives the glassy chew; look for pure starch in the baking aisle. Cornstarch is a workable substitute but produces a slightly softer noodle.

1/2 teaspoon fine sea salt, plus more for the water

Fine sea salt dissolves evenly into the warm mash. Kosher salt works if you use a scant half teaspoon.

1/3 cup (80 ml) neutral oil, such as grapeseed or canola

A neutral oil lets the chili and garlic speak clearly. Do not use olive oil here, as its flavor fights the sesame.

3 tablespoons (18 g) coarse Sichuan chili flakes

Coarse flakes bloom without scorching; fine powder burns in seconds. Gochugaru is a gentler substitute if you want less heat.

4 garlic cloves, finely minced

Fresh garlic is essential for the bloom. Jarred garlic tastes flat and tends to splatter.

2 tablespoons toasted sesame seeds

Toast them yourself in a dry pan for two minutes if they are pale; the aroma deepens noticeably. Black sesame seeds make a striking swap.

3 tablespoons soy sauce

Use regular soy sauce for balance; dark soy is too heavy here. Tamari makes it gluten-free.

1 tablespoon black vinegar

Chinkiang black vinegar gives a malty depth. Balsamic is a decent stand-in, though sweeter.

1 teaspoon sugar

A small amount rounds the heat. Honey can replace it, dissolved first in the warm soy.

2 scallions, thinly sliced

Slice on the bias for pretty curls. Chives are a fine substitute when scallions are absent.

Tips & Tricks

Weigh your potato mash

Too much moisture makes a sticky dough that will not roll. Spread the mash on a plate for five minutes to let steam escape before mixing.

Bloom, do not burn

Pour the oil over the chili flakes at 350 F (175 C) and no hotter. If it smokes, it is already too hot and the flakes will turn bitter.

Dust generously

Keep the work surface and your hands well floured with potato starch, or the ropes will tear as you roll them.

Step-by-Step Instructions

1. Boil and mash

Boil the potatoes in salted water at a gentle rolling boil for 15 to 18 minutes, until a knife slides in with no resistance. Drain, then mash until completely smooth and let the steam rise off for five minutes.

2. Mix the dough

Stir the salt and 1 cup of potato starch into the warm mash, then knead in the remaining starch a little at a time until the dough is soft and no longer sticky. It should feel like a warm earlobe.

3. Rest the dough

Cover the bowl with a damp cloth and let it rest for 10 minutes at room temperature. This short rest lets the starch hydrate so the ropes hold together.

4. Roll the ropes

Dust the counter with potato starch and pinch off tablespoon-sized pieces. Roll each into a rope about 1/2 inch thick, then cut into 2-inch lengths and dust lightly.

5. Bloom the chili oil

Heat the oil in a small saucepan to 350 F (175 C), measured with a thermometer. Pour it over the chili flakes and garlic in a heatproof bowl; it should sizzle and smell toasty, not acrid. Stir in the sesame seeds.

6. Finish the sauce

Whisk the soy sauce, black vinegar, and sugar into the chili oil until the sugar dissolves. Taste and adjust; it should be salty, sour, and warmly hot.

7. Cook the noodles

Bring a pot of salted water to a boil and drop in the noodles. Cook for 3 to 4 minutes, until they float and turn translucent at the edges, then lift them out with a slotted spoon.

8. Toss and serve

Toss the hot noodles directly into the chili oil sauce, adding a splash of noodle water if needed. Scatter the scallions over the top and serve while the oil still shimmers.

Delicious Variations

Sesame Peanut Version

Stir 2 tablespoons of tahini into the chili oil sauce for a nuttier, creamier bowl.

Green Vegetable Addition

Blanch a handful of spinach or bok choy in the noodle water and fold it in at the end.

Cooling Cucumber

Top with thin ribbons of cucumber and extra black vinegar for a summery, refreshing version.

👨‍🍳 Chef's Note: Warm mash absorbs starch far better than cold, so work quickly once the potatoes are drained. If the dough cracks as you roll, a few drops of warm water will bring it back.
