Din Tai Fung’s cucumber salad is salted Persian cucumber marinated in a garlic-soy-vinegar dressing and finished with sesame oil and chili oil. Six pantry ingredients, no cooking, and one non-negotiable: time. The salting and the marinade do all the work, which is why the restaurant’s version tastes deeper than any quick cucumber salad you have made at home.
Most copycats reverse-engineer the dish from taste. There is a shortcut nobody seems to use. Din Tai Fung’s own menu page lists what is in it.
What Din Tai Fung says is in it
The company’s menu description names crisp Persian cucumbers, mild fresno chili peppers, sliced fresh garlic, sesame oil, and the house chili oil. That settles two questions copycat recipes argue about. The cucumber is Persian, the small thin-skinned kind, which is why the rounds stay crunchy instead of collapsing. And the red flecks on top are fresh fresno chili, not just chili flakes from the oil.
What the menu does not print is the marinade, and that is where the copycat community has converged on an answer: light soy sauce, rice vinegar, sugar, and garlic, in roughly equal balance so no single note leads. Sweet, sour, salty, then heat at the end.
Ingredients
- 1 lb Persian cucumbers (about 5 to 6), or 1 large English cucumber
- 1 tablespoon kosher salt, for drawing out water
- 2 tablespoons light soy sauce
- 2 tablespoons rice vinegar
- 1 tablespoon sugar
- 2 cloves garlic, sliced paper thin
- 1 teaspoon toasted sesame oil
- 1 tablespoon chili oil, plus more at serving
- Optional: half a fresno chili in thin rounds, and a pinch of toasted sesame seeds
Rice vinegar can swap for distilled white in a pinch. A good jarred chili crisp works too, though a homemade chili oil lands closer to the house version. Persian and English cucumbers carry less water and more sweetness than standard slicers, which matters more here than any dressing tweak.
Method
- Slice. Cut the cucumbers into thick rounds, about half an inch. Thin slices go limp no matter how well you salt them.
- Salt. Toss the rounds with the kosher salt in a colander set over a bowl and refrigerate for 30 minutes. Water will pool below; that water was the enemy.
- Dry. Rinse quickly, then pat the rounds dry with a towel, harder than feels polite. Any surface water dilutes the dressing on contact.
- Mix. Stir the soy sauce, rice vinegar, sugar, and garlic until the sugar dissolves, then add the sesame oil.
- Marinate. Toss the cucumbers in the dressing, cover, and refrigerate at least 4 hours. Overnight is better, and the flavor keeps building for up to 2 days.
- Serve. Stack the rounds in a small pile, restaurant style, spoon over a little marinade, and finish with chili oil, fresno rounds, and sesame seeds at the table.
The chili oil goes on last for a reason. Stirred into the marinade early, it turns the dressing murky and flat; drizzled at serving, it sits on top in the glossy red pools the restaurant plates are known for.
Why the wait is the recipe
A cucumber is mostly water, and water is the enemy of both crunch and flavor. The 30-minute salt pulls moisture out of the cells so the dressing can move in; the long marinade then carries garlic and vinegar to the center of each thick round instead of just coating the surface. Skip the wait and you get a decent 10-minute cucumber salad, which is a different dish. One home cook on r/dinner logged the honest learning curve:
“I missed this specific salad so much, and after my third attempt at this, it tastes almost identical! 🙂 (Small dinner after a huge lunch)”

Three attempts is about right, and the variable people fix between attempts is nearly always time, not ingredients.
Serving it like the restaurant
At Din Tai Fung the salad lands first, before the dumplings, as a cold sharp opener. It plays the same role at home next to anything rich: our Din Tai Fung Taiwanese cabbage and a pot of rice make a fair copy of the table order, and the house chili oil copycat is the same oil this salad wants on top.
Stored in an airtight container in the marinade, the salad holds 2 to 3 days in the refrigerator. Day two is the peak. After day three the rounds start surrendering their crunch, at which point they still belong on a rice bowl, just not on a plate stacked restaurant style.
FAQ
What makes Din Tai Fung’s cucumber salad unique?
Thick-cut Persian cucumbers that stay crunchy through a long marinade, a balanced garlic-soy-vinegar dressing where no single flavor leads, and chili oil added at serving instead of mixed in. The texture engineering, salting then marinating, is what home versions usually skip.
What kind of cucumber does Din Tai Fung use?
Persian cucumbers, per the restaurant’s own menu description. They are smaller, sweeter, and less watery than standard cucumbers; English cucumber is the closest widely available substitute, cut into the same thick rounds.
Can I make it faster than 4 hours?
A 30-minute marinade after salting produces a good quick version, noticeably lighter in flavor at the center of each round. The 4-hour minimum is where it starts tasting like the restaurant’s, and overnight is where it matches.
Is the cucumber salad healthy?
It is a vegetable in a light dressing: the bulk of the calories come from the sesame and chili oils, roughly a spoonful total across the batch. Using less oil at serving brings it down further without changing the marinade.
