The first time I saw someone smash a cucumber with a rolling pin instead of slicing it, I thought it was a bit of showmanship. It isn’t. The torn, uneven edges hold on to dressing in a way that neat slices never manage, and the difference on the plate is immediate: every piece tastes of sesame and soy rather than just sitting next to it.
This Korean cucumber salad has been my standby for hot evenings ever since. It takes fifteen minutes, most of which is the cucumber sitting in salt while I get on with something else. What comes out is crisp, cool and just savoury enough to hold its own next to anything off the grill.
It also solves the problem every cucumber salad has: watery dressing by the time it reaches the table. Salting the cucumber first draws out the liquid, so the dressing stays where it belongs.
Ingredients for Korean cucumber salad
Before you start, here are the ingredients you’ll need for this recipe. The exact quantities are listed in the recipe card at the end of the article!
For the salad
Cucumber — peeled and smashed rather than sliced, so the dressing has something to cling to.
Carrots — sliced thinly. They bring sweetness and keep their bite longer than the cucumber.
Salt — for drawing water out of the cucumber. This step is what keeps the dressing from turning thin.
For the dressing
Soy sauce — the savoury base. A naturally brewed one has more depth than the cheaper sort.
Sesame oil — toasted, not raw. A teaspoon is plenty, it carries a long way.
Rapeseed oil — neutral, it rounds out the dressing without competing.
Honey — balances the salt. Maple or agave syrup works just as well and makes the salad vegan.
Pepper — freshly ground, a pinch.
To finish
Sesame seeds — toasted, black or white. They go on at the very end so they stay crunchy.
Coriander — chopped or picked into leaves. Spring onion tops are the alternative if coriander isn’t for you.
How to Make Korean Cucumber Salad – Step by Step
The order matters here: the cucumber goes into salt first, and everything else happens while it drains. That way nothing sits around waiting.
Smashing and salting the cucumber
Peel the cucumber and flatten it with a rolling pin or the flat of a chopping board until it splits along its length. Sprinkle generously with salt and set aside for 10 minutes. Rinse, pat dry and break or cut into bite-sized pieces.
The salt is not for seasoning here, it draws out water. Rinsing afterwards is essential, otherwise the salad turns far too salty.
Preparing the carrots and coriander
Slice the carrots thinly, ideally on a mandoline for even pieces. Wash the coriander and either chop it finely or pick off the leaves.
Mixing the dressing
Whisk together the soy sauce, sesame oil, rapeseed oil, honey and pepper until the dressing is smooth and the honey has dissolved completely.
Taste it on its own before it goes onto the salad. It should be slightly too strong, because the cucumber will dilute it.
Bringing it together
Combine the cucumber and carrots in a bowl. Pour over the dressing, mix well and fold in the coriander. Scatter the sesame seeds over the top just before serving.
Tips & Variations
Smashing the cucumber isn’t just for show, it is the actual trick: the split edges take up the dressing far better than smooth slices, and the cucumber gives up its water more readily. Salting and rinsing afterwards matters just as much, otherwise the salad turns watery and the dressing is diluted.
For a version closer to the original, add a finely chopped clove of garlic and half a teaspoon of gochugaru. These Korean chilli flakes are mildly fruity rather than fiercely hot. If you don’t have gochugaru, mild chilli flakes or a finely chopped red chilli will do just as well.
Instead of carrots, thinly sliced radish or spring onion rings work nicely. If coriander isn’t for you, spring onion tops make a good replacement. Swap the honey for maple or agave syrup and the salad becomes vegan. And if you want something more substantial, serve it with rice and a fried egg on top.
Storage
Room temperature: no more than 1 hour. After that the cucumber keeps releasing water and the dressing thins out.
Fridge: covered, it keeps for 1 to 2 days. The salad softens and the flavour deepens. Drain off the liquid before serving and add fresh sesame seeds.
Freezer: not suitable. Cucumber and carrot turn mushy once defrosted.
The dressing on its own is easy to make ahead and keeps in a jar in the fridge for up to a week.
FAQ on Korean cucumber salad
The uneven torn edges take up the dressing far better than smooth slices, and the cucumber releases its water more easily. It is the single thing that makes this salad taste different from an ordinary cucumber salad.
Yes, up to a day ahead. It softens as it sits but the flavour deepens. Add the sesame seeds only just before serving so they stay crunchy.
Not as written, because the dressing contains honey. Swap it for maple syrup or agave syrup and it is vegan.
Mild chilli flakes or a finely chopped fresh red chilli. Gochugaru is fruity rather than sharply hot, so use a lighter hand with anything else.
Most likely the cucumber wasn’t salted long enough or wasn’t patted dry after rinsing. Ten minutes in salt and a proper dry with kitchen paper make the difference.
