Easy Thai Cucumber Salad Recipe
Whenever I want a light and refreshing side dish, I always make this easy Thai cucumber salad recipe. This version uses a signature sweet chili dressing that is such a good pairing for grilled meats like Thai Chicken Sate or savory Thai Fish Cake. Since it is so easy to prep, it is perfect for any meal. This recipe takes only 20 minutes and uses simple ingredients to create a dish that is bursting with bright, tangy flavor.
When you want real Thai restaurant flavor, you need the right balance of crunch and seasoning. One of my favorite things about this salad is how the dressing slightly thickens to coat every piece of cucumber. A few slices of red onion and a topping of crunchy roasted peanuts are all it takes to transform simple cucumbers into something special. This is truly the best Thai cucumber salad recipe for when you want a quick, healthy, and authentic side. Love cucumbers?

Secrets To The Ultimate Crunchy Thai Salad

Just follow these expert tips so your salad has the perfect texture and restaurant quality flavor every time:
- Best Cucumber Varieties: Use firm, heavy cucumbers with smooth skin, such as English or Persian cucumbers, which have thinner skins and fewer seeds. Avoid soft or yellowing ones, as they lack the snap needed for this dish.
- Scraping The Seeds: While you can leave them in, I prefer to scrape the seeds out after peeling. Removing the watery center helps keep the salad from becoming too soggy.
- The Power Of Chunks: Cut your cucumbers into bite sized chunks rather than thin, translucent slices. Thicker pieces provide a more substantial crunch and hold up much better against the salt and dressing without turning limp.
- Salt, Chill, And Drain: Salting the cucumbers in the fridge for 15 minutes is a non negotiable step to draw out moisture. I do not rinse off the salt afterward because it adds a baseline of seasoning to the cucumber itself; however, you must drain the extracted liquid away completely so your sauce does not become watery.
- Preserve The Texture: Always wait until the absolute last second to sprinkle on your chopped peanuts and cilantro. This prevents the peanuts from softening and keeps the cilantro vibrant and aromatic for serving.
Ingredients You’ll Need

- Roasted peanuts

Pro Tip #1: Why I Use Thai Sweet Chili Sauce
I choose Thai sweet chili sauce because it provides an instant base of sweetness and a mild heat. When reduced in a pan, it creates a glossy glaze that clings perfectly to the cucumber chunks.
Pro Tip #2: Why I Use Apple Cider Vinegar
I add apple cider vinegar because it provides a fruity acidity that balances the sugar in the dressing. It offers a bright tang that cuts through the richness of the peanuts and keeps the dish refreshing.
Pro Tip #3: Why I Add Red Onion
I use thinly sliced red onion for a sharp, crisp bite and a beautiful pop of color. The mild pungency perfectly cuts through the sweet chili dressing. I avoid yellow or white onions because their raw heat is too harsh and lingering.
Pro Tip #4: Why Roasted Peanuts Are Essential
I always add chopped roasted peanuts right before serving for that authentic Thai texture. They provide a nutty, savory crunch that contrasts beautifully with the juicy, chilled cucumbers.
How To Make Thai Cucumber Salad

Add salt to the prepared cucumbers, mix well, and set them aside in the fridge for 10 to 15 minutes.
Pro Tip: I chill the cucumbers so they stay incredibly crisp and maintain that signature refreshing snap.

Combine the Dressing ingredients in a small saucepan. Turn on the heat and reduce the dressing slightly until it is lightly thickened, then let it cool completely.

Remove the cucumbers from the fridge and drain the salt water completely to keep them crunchy.

Toss the cucumbers and sliced red onions together, then mix thoroughly with the cooled dressing.

Top with the chopped roasted peanuts and cilantro, and serve immediately for the best texture!
Frequently Asked Questions
Yes, this recipe is naturally vegan as long as your Thai sweet chili sauce does not contain honey or fish sauce.
It is best to prepare the dressing and cucumbers separately ahead of time. Combine them and add the peanuts right before you serve to keep the salad from getting watery.
Rice vinegar is a great substitute that maintains the authentic Asian tang required for the dressing.
Heating and reducing the dressing in a saucepan helps it thicken slightly. This allows the sauce to coat the cucumbers much better than a thin vinaigrette.
This usually happens if the salt water wasn’t drained completely or if the dressing was still warm when added. Make sure to drain the cucumbers well and let the sauce cool to room temperature first.
If you have leftovers, store them in an airtight container in the refrigerator for up to 24 hours.

If you like Thai flavors, you will NOT be disappointed! Thank you for posting this delicious salad recipe.

Hi D thanks for trying my Thai Cucumber Salad recipe. Thanks for trying other recipes, too. :)
Try Rasa Malaysia’s Malaysian chicken sates. They’re the best ever.
Did you ever hear the saying ‘if you don’t have anything good to say, don’t say anything’? If you don’t like it don’t make it but don’t criticize needlessly.
We love this cucumber salad and make it all the time. Everyone loves it even people who don’t like cucumbers. Delicious!
Great simple salad that is FULL of flavor. I completely deseeded my cucumber and sliced it into “moons”. I love how the cucumber stays crisp because you salt it first. The dressing is not too sweet, and balances well with the red onion.
Hi Vera thanks for trying my Thai cucumber salad.
Yummy, made it but left the cilantro out as I loathed taste and smell. I also cut the seeds out of the middle of the cucumber as it gives my mother heartburn. But it tasted the same and now a welcome and well loved recipe, many thanks
Thanks for trying this cucumber salad recipe!
Amazing salad very delicious and super easy to make!
Awesome, I am so happy to hear that you love my Thai Cucumber Salad recipe.
Best cucumber salad I’ve ever had! Prepared it exactly according to recipe— thought it would be too sweet but it wasn’t. Making it again ( for the third time this week! ) and not changing a thing. Salting the cucumber first, as the recipe says, is an important step. Drain the salt water ( don’t rinse it off ). Excellent recipe! Thanks!
