Viral Cucumber Salad (TikTok)
The smashed cucumber salad that took TikTok by storm: cucumbers are smashed to create craggy, sauce-trapping pieces, then dressed with soy sauce, rice vinegar, sesame oil, garlic, and chilli oil for a cool, crunchy, bold side dish ready in under 15 minutes.
What is this dish?
The viral smashed cucumber salad is a Chinese-inspired technique (pai huang gua) that became a global TikTok sensation: cucumbers are smashed rather than sliced to create irregular, dressing-trapping pieces, then dressed with a bold combination of soy sauce, rice vinegar, sesame oil, garlic, and chilli oil. The result is a cool, crunchy salad that is simultaneously refreshing and deeply flavoured — and requires no cooking whatsoever.
Why you'll love it
This salad takes under 15 minutes start to finish. There is no cooking, no heat, and minimal washing up. Despite the simplicity, the flavour is bold and complex — the contrast of cool crunchy cucumber against the warm sesame-soy-chilli dressing is genuinely addictive. It is vegan, gluten-free (with tamari), very low calorie, and works as a side dish, a starter, or a light snack.
When to serve
Perfect as a side dish alongside grilled meats, noodle dishes, or rice bowls. Excellent as a starter at an Asian-inspired dinner. Works as a refreshing snack on a hot day. Pairs well with any grilled protein for a quick weeknight meal.
Quick tips
Smash don't slice — the craggy surface traps the dressing. Salt and drain the cucumber first or the dressing will be watery. Serve quickly after dressing. Use English or Persian cucumbers for the best texture.
Smashed Cucumber
The technique is the ingredient — smashing creates irregular, rough surfaces that grip the dressing entirely differently from smooth knife-cut slices. The same cucumber with the same dressing tastes dramatically more flavourful when smashed rather than sliced.
Toasted Sesame Oil
A finishing oil used in small amounts for its intensely nutty, aromatic flavour. Toasted sesame oil (dark in colour) is very different from regular sesame oil — the toasting process produces the characteristic deep, roasted sesame fragrance that defines the dressing. Do not use regular (untoasted) sesame oil as a substitute.
Chilli Oil
Provides heat and a deep, roasted chilli flavour that regular chilli sauce cannot replicate. Chilli crisp (with fried garlic and shallot pieces) adds both heat and additional texture. The amount used directly controls the heat level of the finished salad.
Rice Vinegar
A mild, slightly sweet vinegar that provides balanced acidity without the sharpness of white or red wine vinegar. The gentle tang of rice vinegar complements the other ingredients without dominating.
Substitution Options
Tamari replaces soy sauce for a gluten-free version with identical flavour. Apple cider vinegar replaces rice vinegar with a slightly sharper result. Regular sesame oil (light, untoasted) can replace toasted sesame oil but the flavour will be considerably less intense and the result less satisfying — increase the amount to compensate. Sriracha or sambal oelek can replace chilli oil though the flavour profile will differ.
Step-by-Step Instructions
Smash and salt the cucumbers
Trim the ends off each cucumber. Place a cucumber on a chopping board and lay the flat side of a large knife or cleaver on top. Press down firmly with the heel of your palm to smash the cucumber — it should crack, split, and flatten irregularly. Repeat along the length of the cucumber. Break or cut the smashed cucumber into rough 3–4cm pieces by hand or with a knife. Transfer to a colander and toss with 1 teaspoon of salt. Leave to drain for 10 minutes over the sink or a bowl.
Pro Tips:
- •The smashing is not just theatrical — it creates uneven, craggy surfaces with more texture than sliced cucumber, and those irregular surfaces trap and hold the dressing far more effectively.
- •Do not over-smash — the goal is cracked and split, not completely pulverised. A few firm strikes are sufficient.
Make the dressing
While the cucumber is draining, combine the soy sauce, rice vinegar, sesame oil, chilli oil, and sugar in a small bowl. Whisk until the sugar is dissolved. Add the minced garlic and grated ginger (if using) and stir to combine. Taste — the dressing should be bold, salty, tangy, slightly sweet, with a background heat from the chilli oil.
Pro Tips:
- •Adjust the ratios to your preference — more rice vinegar for extra tang, more chilli oil for more heat, more soy sauce for more saltiness.
- •Mincing the garlic very finely (or grating on a microplane) ensures it distributes evenly and does not leave raw, sharp chunks.
Drain, dress, and serve
After 10 minutes of salting, squeeze the cucumber pieces gently in your hands over the sink to remove excess water, or pat dry with kitchen paper. Transfer to a serving bowl. Pour the dressing over the cucumber pieces and toss thoroughly to coat. Scatter the toasted sesame seeds and sliced spring onions over the top. Serve immediately or refrigerate for up to 30 minutes for slightly more developed flavour — the cucumber will soften slightly on longer standing.
Pro Tips:
- •Squeeze out as much water as possible from the salted cucumber — excess water will dilute the dressing and make the salad watery.
- •Serve quickly — this is best eaten within an hour of dressing. The longer it sits, the more water the cucumber releases.
Chef's Tips
Techniques that separate good from great
The smashing technique is the key to the recipe
A smooth knife cut creates a neat, even surface on cucumber with nothing to grip onto. Smashing the cucumber with a flat blade creates hundreds of irregular fractures, rough surfaces, and small pockets that the dressing soaks into and clings to. The result is cucumber that tastes intensely flavoured all the way through rather than merely coated on the outside. This is why the same dressing on sliced cucumber tastes noticeably less impactful.
Chilli crisp oil versus plain chilli oil
If available, use chilli crisp oil (such as Lao Gan Ma brand) rather than plain chilli oil. Chilli crisp contains fried garlic and shallot pieces suspended in chilli-infused oil, adding both heat and an additional layer of crunchy, savoury texture to the finished salad. It is now widely available in most supermarkets and Asian grocery stores and is the version used in the viral TikTok iterations of this recipe.
Serve immediately after dressing
Even after properly salting and draining, cucumber continues to release water once it is dressed with the acidic, salty dressing. The salad is at its absolute best immediately after tossing — the cucumbers are still properly crisp and the dressing is concentrated. After 30–45 minutes, the dressing begins to dilute noticeably. If preparing ahead, keep the cucumber and dressing separate and combine just before serving.
Nutrition Facts
Equipment Needed
- Large knife or cleaver (for smashing)
- Chopping board
- Colander
- Small mixing bowl (for dressing)
- Serving bowl
Quick Tips
- Salting and draining the cucumber is essential — cucumbers contain a lot of water, and without this step the dressing will be diluted and the salad will turn watery within minutes of serving.
- Use English or Persian cucumbers rather than regular large cucumbers — they have thinner skin, fewer seeds, crisper flesh, and a more delicate, less bitter flavour. Regular cucumbers can be used but should be peeled and deseeded first.
- Make the dressing while the cucumbers drain — the 10-minute salting time is enough to get everything else ready.
Recipe Variations
Different ways to make this dish your own
Cucumber Salad with Peanut Sauce
Replace the chilli oil and sesame oil with 2 tablespoons of smooth peanut butter thinned with a little warm water, 1 tablespoon of soy sauce, 1 tablespoon of rice vinegar, and 1 teaspoon of sugar. The result is a rich, nutty cucumber salad popular throughout Southeast Asia.
Korean-Style Cucumber Salad (Oi Muchim)
Replace the soy sauce with 2 tablespoons of gochugaru (Korean chilli flakes), add 1 teaspoon of fish sauce (or soy sauce), and 1 teaspoon of sugar. The Korean chilli flakes provide a distinctive sweet-spicy heat different from Chinese chilli oil.
Cucumber and Avocado Salad
Add 1 ripe avocado, cubed, to the dressed cucumber. The creamy avocado contrasts beautifully with the crunchy cucumber and balances the bold dressing. Serve immediately — avocado discolours quickly once cut.
Extra Crunchy with Fried Shallots
Scatter 2 tablespoons of store-bought crispy fried shallots over the finished salad immediately before serving. The extra crunch and caramelised shallot flavour elevates the dish significantly.
What to Serve With
Perfect pairings to complete the meal
Steamed Jasmine Rice
Serve the cucumber salad alongside a bowl of steamed jasmine rice for a complete, light meal. The rice balances the bold, salty dressing.
Grilled Chicken or Tofu
A simple grilled protein alongside turns the side salad into a full meal — the cool, tangy cucumber contrasts excellently with warm grilled protein.
Noodle Bowl
Use as a topping for cold sesame noodles or a soba noodle bowl for a fully composed Asian-inspired meal.
As a Starter
Serve in small portions as a refreshing, palate-stimulating starter before a richer main course.
Storage & Make-Ahead
Keep it fresh and plan ahead
Refrigerator
Store undressed cucumber pieces for up to 2 days in the refrigerator. Once dressed, the salad is best eaten within 1 hour. After this time the dressing dilutes and the cucumber softens. Store dressing separately and combine to order.
Freezer
Not suitable for freezing — cucumber becomes limp and watery on thawing.
Make-Ahead
Salt, drain, and squeeze the cucumber up to 2 hours ahead. Make the dressing in advance. Combine just before serving for the best texture.
Reheating
Not applicable — this dish is served cold and raw.
