These spicy peanut noodles are the recipe I reach for when I want something fast, comforting, and full of flavour with almost no effort. The sauce is built on classic Taiwanese sesame noodles, using nutty peanut sesame paste as the base, then given a gentle kick with a gochugaru chilli oil mixture.

Ready in 15 minutes with pantry staples, it works just as well as a quick lunch, a weeknight dinner, or a very good excuse for second helpings at midnight.

Why You’ll Love This Recipe

Creamy, nutty, mildly spicy – a rich peanut sauce balanced with garlic, vinegar, soy sauce, and gochugaru.
Easy to customise – swap in your favourite protein or vegetables without changing the sauce.

The Secret to the Sauce

The key ingredient in this recipe is Asian peanut sesame paste. Unlike tahini, which is made purely from sesame seeds, peanut sesame paste combines roasted sesame with peanuts to create a richer, toastier flavour that’s commonly used in Taiwanese sesame noodles.

It creates a sauce that’s smooth, creamy, and packed with nutty aroma. If you can’t find peanut sesame paste, smooth peanut butter is a much better substitute than tahini.

Tips for This Recipe

Add the Water Gradually : When mixing water into the peanut sesame paste, add it a little at a time while stirring continuously. The paste will loosen gradually into a silky, smooth sauce. Adding too much water at once can cause the sauce to separate or become too thin.
Hot Oil Sizzling : Pouring hot oil over the gochugaru, garlic, spring onion, and sesame seeds releases their aroma and creates a much more fragrant sauce. It’s a simple step that makes a big difference.
Adjust the Flavours to Your Taste : Everyone likes their peanut noodles a little differently. Add more vinegar for extra tang, more gochugaru for additional heat, or a little extra soy sauce if you prefer a saltier finish.
Don’t Substitute Tahini : Although tahini may seem like an obvious alternative, I don’t recommend it for this recipe. Tahini is made from sesame seeds only and has a more earthy, slightly bitter flavour. Peanut sesame paste (or smooth peanut butter if needed) gives the sauce the rich, roasted, nutty flavour that makes these noodles so delicious.

Final Thoughts

These spicy peanut noodles show what a handful of pantry ingredients can do in fifteen minutes: a creamy peanut sauce, fragrant aromatics, and gentle heat from the gochugaru. Simple to make, and worth putting on repeat.

Ingredients

1 pack Asian noodles of your choice
Cucumber strips optional
Sesame seeds to garnish

FOR THE SAUCE

1 tbsp Gochugaru Korean chilli powder
1 tbsp sesame seeds
1 tbsp chopped spring onion
1 tbsp chopped garlic
2-3 tbsp vegetable oil
1-2 tbsp soy sauce
1 tbsp white vinegar
2 tbsp Chinese sesame peanut paste or smooth peanut butter
2-4 tbsp water, or as needed

Instructions

Make the chilli oil: In a heatproof bowl, combine the gochugaru, sesame seeds, spring onion, and garlic. Heat the vegetable oil in a small saucepan over medium-high heat until shimmering, then carefully pour it over the mixture — it should sizzle immediately. Add the soy sauce and white vinegar, then stir to combine.
Finish the sauce: Add the peanut paste to the chilli oil mixture. Add water a little at a time, stirring continuously until the sauce is smooth and reaches your preferred consistency.

Taste the sauce and adjust the soy sauce and vinegar to your liking.

When loosening the peanut paste, add the water gradually — a little at a time — and stir slowly until you reach your preferred consistency. This prevents the sauce from becoming too thin.

Cook the noodles: Cook the noodles according to the packet instructions until al dente. For a springier, chewier texture, rinse under ice-cold water straight after cooking, then drain thoroughly. Otherwise, simply drain and use straight away.

Rinsing the noodles in ice-cold water stops the cooking process and gives them a springier, chewier bite — well worth it if you have a moment!

Assemble: Transfer the noodles to a serving bowl and add the cucumber strips if using. Pour over the sauce and top with sesame seed. Serve immediately.

Use egg-free noodles for a vegan version, or swap in gluten-free noodles and gluten-free soy sauce for a gluten-free one.
