Ingredients

14 ounces potato noodles
¼ cup chili oil with chili flakes
4 cloves garlic finely minced
3 tablespoons soy sauce
1 tablespoon Chinese black vinegar
2 teaspoons granulated sugar
1 tablespoon toasted sesame seeds
2 green onions thinly sliced and divided
¼ cup crushed roasted peanuts
Chopped cilantro for garnish (optional)
Chili crisp for serving (optional)

Instructions

Bring a large pot of water to a boil. Cook the potato noodles according to the package directions until tender and chewy. Before draining, reserve ¼ cup of the noodle cooking water.
Place the minced garlic and toasted sesame seeds in a large heatproof bowl.
Heat the chili oil in a small saucepan over medium heat until hot and shimmering. Carefully pour the hot oil over the garlic and sesame seeds. Stir immediately and allow the mixture to bloom for about 30 seconds.
Add the soy sauce, Chinese black vinegar, and sugar. Stir until the sugar dissolves and the sauce is well combined.
Add the hot drained noodles and half of the green onions to the bowl. Toss thoroughly until the noodles are evenly coated. Add 1 to 2 tablespoons of the reserved noodle water if needed to create a glossy sauce.
Divide the noodles among serving bowls.
Top with the remaining green onions, crushed peanuts, cilantro, and chili crisp if desired.
Serve immediately while hot.

Notes

Why Potato Noodles Work So Well

Potato noodles have a uniquely chewy, springy texture that makes them perfect for soaking up bold sauces. Unlike traditional wheat noodles, they have a mild flavor that allows the spicy chili oil, savory soy sauce, and tangy black vinegar to stand out in every bite.

Use Chinese Black Vinegar

For the most authentic flavor, use Chinese black vinegar rather than regular vinegar. Black vinegar adds a rich, slightly sweet tanginess that balances the heat from the chili oil and creates a more complex, restaurant-style sauce.

Don't Skip Blooming the Aromatics

Heating the chili oil before pouring it over the garlic and sesame seeds is an important step. The hot oil blooms the aromatics, releasing their flavors and creating a fragrant base for the sauce. This simple technique adds incredible depth and aroma to the finished dish.

Reserve Some Noodle Water

Before draining the noodles, save a small amount of the cooking water. The starch in the water helps emulsify the sauce, creating a silky texture that clings beautifully to the noodles instead of pooling at the bottom of the bowl.

Serve Immediately for the Best Texture

Potato noodles are best enjoyed right after they are tossed with the sauce. As they cool, they can become sticky and absorb more of the liquid, which may make the dish seem drier over time.

Adjust the Spice Level

This recipe has a medium level of heat, but it is easy to customize. For a milder version, use less chili oil or a mild chili crisp. For extra spice, add additional chili flakes, chili crisp, or a pinch of ground Sichuan peppercorns.

Add Protein for a Complete Meal

These noodles are satisfying on their own, but they also pair wonderfully with soft-boiled eggs, crispy tofu, shredded chicken, ground pork, or sautéed shrimp. Adding protein transforms this simple noodle dish into a complete meal.

Try Your Favorite Vegetables

For extra color and nutrition, toss the noodles with sautéed bok choy, napa cabbage, spinach, mushrooms, or snap peas. The vegetables complement the bold chili oil sauce without overpowering it.

Make It Your Own

One of the best things about chili oil potato noodles is how customizable they are. Add peanut butter for a creamy peanut version, sprinkle on crushed peanuts for crunch, or stir in chili crisp for even more texture and flavor. No matter how you serve them, the combination of chewy noodles and spicy chili oil is always delicious.
