Why You’ll Love This Cold Sesame Peanut Noodle Salad
- Ready in under 20 minutes: The noodles boil while you whisk the dressing — dinner is genuinely on the table faster than most pasta dishes.
- Minimal washing up: One pot for the noodles, one bowl for the dressing, and a pair of tongs. That’s it. No frying pans, no chopping boards covered in oil.
- Make-ahead magic: This salad actually improves after a few hours in the fridge, meaning you can prep it at lunchtime and have zero work to do at dinner.
- Crowd-friendly ingredients: No obscure supermarket finds here — everything comes from a standard grocery shop, and the peanut butter base keeps even picky eaters coming back for seconds.
- Naturally adaptable: Add leftover shredded chicken, swap the veg based on what’s wilting in your crisper drawer, or double the batch for tomorrow’s lunchboxes without any extra effort.
Ingredients You’ll Need
- 300g dried udon noodles (or thick spaghetti, if that’s what you have)
- 4 tablespoons smooth peanut butter
- 2 tablespoons soy sauce
- 1 tablespoon toasted sesame oil
- 1 tablespoon rice vinegar
- 1 teaspoon honey or maple syrup
- 1 clove garlic, finely grated
- 1 teaspoon fresh ginger, finely grated
- 2 tablespoons warm water (to thin the dressing)
- 1 large carrot, peeled into ribbons
- 1 cucumber, halved and thinly sliced into half-moons
- 3 spring onions, thinly sliced on the diagonal
- 1 tablespoon sesame seeds, toasted
- Fresh coriander leaves, a handful (optional, but lovely)
Tip: If you’re planning to make this ahead, keep the sesame seeds and coriander separate until just before serving — they stay crunchier and brighter that way.
How to Make Cold Sesame Peanut Noodle Salad
- Cook the noodles: Bring a large pot of salted water to a rolling boil — you should see big, steady bubbles breaking the surface. Drop in the udon noodles and cook according to the package instructions, usually 6–8 minutes. Stir once halfway through to prevent sticking; the noodles will turn from opaque to a glossy, translucent white when they’re done. Drain into a colander and rinse under cold running water until the noodles feel cool to the touch — this stops the cooking and removes excess starch. Shake the colander well to get rid of as much water as possible, then set aside.
- Make the dressing: While the noodles boil, grab a medium mixing bowl. Add the peanut butter, soy sauce, toasted sesame oil, rice vinegar, honey, grated garlic, and grated ginger. Whisk vigorously with a fork — the mixture will look thick and clumpy at first, almost like a stiff paste. Add the warm water, one tablespoon at a time, whisking after each addition. The dressing will loosen into a smooth, pourable consistency that coats the back of a spoon. Taste it: you’re looking for a balance of salty, nutty, and slightly sharp. Adjust with a splash more vinegar if it feels too rich.
- Prepare the vegetables: Using a vegetable peeler, run it down the length of the carrot to create thin ribbons — they should curl slightly and feel pliable. Slice the cucumber in half lengthways, then cut each half into thin half-moons about half a centimetre thick. Slice the spring onions on a sharp diagonal so you get pretty green and white rings. These vegetables add crunch and freshness to balance the rich dressing.
- Combine everything: Tip the cooled, drained noodles into the bowl with the dressing. Add the carrot ribbons, cucumber slices, and most of the spring onions (reserve a few for garnish). Using tongs or two large forks, toss everything together gently but thoroughly. Lift the noodles from the bottom and fold them over the top until every strand is glossed with dressing — you should see the sauce clinging evenly, with no dry patches of noodle left.
- Finish and serve: Transfer the salad to a serving platter or individual bowls. Sprinkle over the toasted sesame seeds, the reserved spring onions, and a scattering of fresh coriander leaves if using. The contrast of the pale noodles against the orange carrot ribbons and green cucumber makes this dish look as good as it tastes. Serve immediately for a cold, refreshing dinner, or cover and refrigerate for later.
Tips From My Kitchen
- Rinse the noodles thoroughly: Hot noodles straight from the pot will seize up and become claggy if you dress them immediately. I always rinse mine under cold water for a good 30 seconds, then shake the colander hard to remove every last drop. Dry noodles grab the dressing much better than wet ones — it’s the single most important step for a silky, non-gluey result.
- Grate the garlic and ginger finely: A rough chop leaves you with sudden, overwhelming bites of raw garlic. I use a microplane or the finest side of a box grater, which turns the garlic and ginger into a paste that melts seamlessly into the dressing. You get all the flavour without anyone finding a surprise chunk.
- Toast your sesame seeds: This takes exactly 90 seconds in a dry frying pan over medium heat, shaking the pan frequently. The seeds will turn from pale cream to golden brown and release a nutty, toasty aroma that fills your kitchen. Skipping this step means losing a layer of depth that really lifts the finished dish.
- Make the dressing in advance: I often whisk the dressing up in the morning and store it in a jar in the fridge. It thickens slightly as it sits, so when I’m ready to use it, I add an extra teaspoon of warm water and shake vigorously. This separates the active cooking from the serving time beautifully.
- Double the batch on purpose: This salad keeps brilliantly in the fridge for up to two days, making it ideal for packed lunches or a no-effort dinner the following night. Just stir in a splash of soy sauce or water before serving if the noodles have absorbed some of the dressing overnight.
Common Mistakes to Avoid
- Overcooking the noodles: Mushy, bloated noodles ruin the texture of this salad completely. Set a timer for the minimum cooking time on the packet and test a strand — it should be tender but still offer some resistance when you bite through it. The cold rinse will firm them up slightly, but you can’t rescue noodles that started out waterlogged.
- Using cold peanut butter straight from the fridge: Chilled peanut butter is stiff and refuses to blend smoothly into the other ingredients. Let it sit at room temperature for ten minutes, or microwave it in a small bowl for ten seconds before whisking. A warm, soft peanut butter emulsifies with the liquids far more easily, giving you a silky dressing instead of a lumpy one.
- Skipping the rest time for make-ahead: If you’re serving this immediately, you can dig right in. But if you’re prepping it for later, don’t serve it straight from the fridge without letting it sit for ten minutes at room temperature. Cold dressing can taste muted and flat; a short rest allows the flavours to open up and the sesame oil to shine through again.

Frequently Asked Questions
Can I use a different type of noodle?
Absolutely. Udon noodles give that satisfyingly thick, chewy texture I love, but thin spaghetti, soba noodles, or even rice vermicelli work beautifully here. Just adjust the cooking time to whatever your chosen noodle requires and rinse them thoroughly under cold water afterwards.
How do I stop the noodles from sticking together after rinsing?
After draining and rinsing, toss the noodles with a teaspoon of toasted sesame oil directly in the colander. The thin coating of oil acts as a barrier, keeping each strand separate while you finish the dressing. This trick has saved me from wrestling with a solid block of noodles more times than I can count.
Can I make this salad nut-free?
Yes, and it’s simpler than you might think. Replace the peanut butter with sunflower seed butter or tahini — both create a similarly creamy, rich dressing. You’ll need to add an extra teaspoon of honey or maple syrup to balance the slight bitterness of tahini, but the result is just as delicious.
Is this salad suitable for lunchboxes?
It’s one of the best lunchbox salads I know. Pack the salad in a sealed container and keep the sesame seeds and coriander in a small separate baggie. Add those just before eating and the salad stays fresh, crunchy, and vibrant for hours without turning soggy.
Why is my dressing too thick?
Peanut butter brands vary wildly in consistency — some are naturally runnier than others. If your dressing looks more like a paste than a sauce, add warm water one teaspoon at a time, whisking between each addition, until it reaches a smooth, drizzling consistency. The dressing should coat the noodles lightly, not clump on them.
