Spicy Potato Noodles are a bold, flavorful twist on traditional noodle dishes — the chewy homemade potato-based strands soaked in a hot chili oil sauce will grab your attention right away. Starting with simple ingredients — yellow potatoes, potato starch, water — you’ll shape, boil, and dress these noodles to create a satisfying main dish with punchy garlicky, tangy, spicy sauce. Whether you’re cooking for yourself or sharing with friends, this dish brings texture, heat, and comfort all at once.
Why You’ll Love This Recipe
You’ll fall for these potatos-noodles because of the unique texture and vibrant sauce. Unlike regular wheat noodles, the potato-and-starch dough yields a chewy “bounce” that stands up to the chili oil coating. The sauce brings garlic, chili flakes, gochugaru (Korean red pepper powder), black vinegar and soy sauce — deep umami, tang and heat balanced by a hint of sugar. Because the noodles are relatively neutral in flavor, the sauce shines. Plus you get the satisfaction of shaping your own noodles — a fun kitchen ritual. And it’s customizable: you control the thickness of the noodles and the spice level to suit your taste.
Ingredients
Potato Noodles
- 2 medium yellow potatoes (~500 g / 1.1 lb)
- 2 cups potato starch (~400 g)
- ½ cup water (room temperature, ~120 ml)
Chili Oil Sauce
- 3 cloves garlic (finely chopped)
- 1 stalk green onion (sliced)
- 1 tbsp Korean chilli powder (gochugaru)
- 2 tsp crushed red pepper
- ½ tsp granulated sugar
- 1 tbsp dark soy sauce
- 1 tbsp light soy sauce
- 1 tbsp Chinese black vinegar
- ¼ cup vegetable oil
Garnish
- 1 tsp roasted sesame seeds
Step-by-Step: How to Make Spicy Potato Noodles
- Peel the yellow potatoes, chop them into chunks, and boil until tender (a fork easily pierces).
- Drain and transfer the hot potatoes to a bowl, then mash finely so there are no large chunks.
- Immediately add the potato starch and water, and mix / knead until you have a firm, smooth dough ball. It helps when the potatoes are still warm.
- Roll the dough into a long log shape, then cut into 16 pieces (or adjust number depending on how thick you want the noodles to be).
- Take each piece and roll it into a chopstick-length strip (or your preferred noodle length).
- Bring a pot of water to boil. Carefully drop the potato noodles in and cook for around 5 minutes or until fully cooked (they may float).
- Transfer the cooked noodles into cold water, drain them, then place into a serving bowl.
- Prepare the chili oil sauce: combine garlic, green onion, chilli powder, crushed red pepper, sugar, dark soy sauce, light soy sauce, black vinegar in a heat-proof bowl. Heat the vegetable oil until shimmering and carefully pour the hot oil over the sauce mixture — it will sizzle and release aroma.
- Pour the sauce over the drained noodles and toss gently so everything is coated.
- Garnish with roasted sesame seeds and serve immediately while warm.
Note: If your dough is cracking or brittle, it may be too dry — add a few drops of water. If too wet/sticky, add a bit more starch.
Helpful Tips
- Work quickly while the dough and potatoes are still warm — warm dough is more pliable and less likely to break when shaping.
- Use a wide pot for boiling noodles so they lie flat and don’t curl/break.
- Keep dough pieces covered with a damp towel if you’re not shaping immediately, to prevent them drying out.
- Adjust thickness and cooking time: thicker noodles will take slightly longer; thinner ones will cook faster but are more fragile.
- You can adjust spice level by reducing crushed red pepper or gochugaru.
- For the hot oil pour: use caution — hot oil + sauce ingredients = dramatic sizzle and airflow.
- Serve right away: the texture is best when warm; if cooled, the chewiness and bounce reduce.
Substitutions and Variations
- Potato choice: Yellow potatoes are recommended for their slightly sweet/earthy flavor and good texture for these noodles. You could use russet, though texture may differ.
- Starch variant: The recipe uses potato starch; you could experiment with tapioca starch but it changes texture slightly. Cornstarch is less favourable due to difference in chew.
- Sauce variations: Swap in tamari (for gluten-free), use rice vinegar if black vinegar unavailable (though flavor changes).
- Shape & size: Instead of long noodles, you could roll into short gnocchi-like bits.
- Additional mix-ins: Add some sautéed vegetables (bell pepper, spinach), shredded chicken or tofu if you want a more substantial bowl.
- Serving style: Serve hot as a main; or serve cooled with a crisp veggie side for a cold noodle salad twist.
- Switch up spice level: For mild version, reduce gochugaru and crushed red pepper; for extra heat, add chilli oil or extra flakes.
Storage Instructions
- These noodles are best enjoyed fresh — texture (chewy bounce) is optimal right after cooking.
- If you have leftovers: allow to cool completely, then store in an airtight container in the fridge for up to 2-3 days.
- Reheating: You can microwave loosely covered until warm; or simmer briefly in boiling water (if un-sauced) to restore chewiness.
- Note: The homemade dough may firm up when chilled; warming restores better texture.
Nutritional Information

Because this recipe uses simple ingredients (potatoes, potato starch, vegetable oil, soy sauce, chili flakes, garlic) the macros will depend on serving size and optional add-ins. Key points:
- The base noodle is essentially potato + starch — primarily carbohydrates.
- The sauce adds oil, soy sauce (which includes sodium), and chili/spices.
- If you wish to lighten it: reduce oil, serve smaller portion, pair with high-fiber veggies or green salad.
- If you need gluten-free: ensure soy sauce is gluten-free or use tamari.
Serving Suggestions
- Serve the noodles in a large bowl, garnish with sliced green onion or cilantro for a fresh herbal touch.
- Add a side of crisp, crunchy vegetables (cucumber salad, shredded carrot) to contrast the chewy noodle texture.
- A simple protein like grilled chicken strips, tofu cubes or a fried egg on top pairs nicely.
- For a full meal: pair with a light miso soup or steamed greens.
- If you like extra heat, serve with a small dish of extra chili oil/flakes for diners to add as desired.
- Enjoy immediately while warm to best experience the chewy texture and vibrant sauce.
Frequently Asked Questions About Spicy Potato Noodles
Here are answers to some common questions you might have about making or serving this recipe.
Q: What do potato noodles taste like?
A: Because they’re made from potato and potato starch, the noodles themselves have a mild, slightly earthy and subtly sweet flavor. The real flavor punch comes from the sauce you toss them in. The texture is chewy and bouncy — more so than typical wheat-based noodles.
Q: Can I use potato flour instead of potato starch?
A: It’s not recommended. Potato flour behaves differently — you’ll lose the signature chewy bounce and may get a crumbly or gummy texture. Potato starch is the better match.
Q: How thick should I roll the noodles and how many pieces should I divide the dough into?
A: The recipe suggests dividing into 16 pieces for very thick noodles. If you prefer thinner noodles, divide into more pieces or roll shorter; just adjust cooking time accordingly. Note that thicker noodles yield a chewier experience.
Q: Can I make these ahead of time?
A: You can, but for best texture the noodles should be served soon after cooking. If you make them ahead, refrigerate and then gently reheat; the chew will be a bit reduced. Storage is possible for up to 2-3 days.
Q: I don’t have Chinese black vinegar — can I substitute?
A: Yes, you can use white vinegar or rice vinegar, but the flavor will differ slightly (less deep, caramel note). You may want to adjust the amount to avoid overly sharp vinegar flavor.
