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
- Cucumber
- Thai sweet chili sauce
- Apple cider vinegar
- Red onion
- Roasted peanuts
Check the recipe card at the bottom of this post for all the ingredient details.
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.

Can I make the dressing a day before and refrigerate it?
Yes.
I made this recipe today. Family gave raving reviews. Thank you for the recipe! I also added some chopped up pineapple for sweetness :) This is a keeper! Will make it again next time
:)
So you rinse the salt of the cucumber?
You don’t rinse just follow the instructions in the recipe card.
Great salad! Sweet, crunchy, a bit hot but not too much. I scrape the seeds out of the cucumbers prior to salting themas it helps to limit the water content of the cucumbers.
You are brilliant!
Prepared this salad this evening. The t turned out amazing. I did cut back on the two tablespoons of peanuts to one.
Awesome!
So yummy definitely try it
Made this and served with Sriracha Chicken. Absolutely beautiful. I did julienne very finely some red capsicum to add to the salad and I didn’t bother reducing the dressing. Just gave it a good shake to dissolve the sugar. Everyone is now addicted
The water is in the dressing to help dissolve sugar, as I read it anyway and to balance sweetness :)
Thanks….a real keeper :)
Awesome!
Love all things cucumber. I haven’t tried Thai salad before. I’ll have to try this when the weather warms up.
Doesn’t the moderator answer the questions. I’m thinking of making this
Can’t wait to try this! Just a question–are the 2 T water for use in the dressing or to mix with salt and soak the cucumbers? The reason I ask is that Step 2 says to drain the salt water from the cucumbers, but the recipe says only to mix salt with the cucumbers (no water). Thanks!
I had the same question as you, Amber. Since I had to guess on my own, I think it’s that the cukes are supposed to release water as they sit, so that is what you are supposed to drain-off. My cukes didn’t release any water after I sprinkled them with the salt, so I just carried-on and everything turned-out perfectly.
The salt helps to pull the water out from the cucumbers so as not to have a watery salad. :)
Salt will draw out the water from the cucumbers, dehydrating them a bit so you don’t end up with a lot of extra liquid.
Salt cucs and onion ,
Water is for dressing.
After trying several versions of this over the years, this one is the best! I cut my cucumber in ribbons but otherwise followed the recipe exactly. It has the perfect balance of sweet, tang and heat. It went very well with our chicken satay, but I will make this often, even when I’m not cooking Thai food! Also, it’s very pretty! Delicious and refreshing. I love your recipes!
Thank you! This is amazing to hear. I appreciate it.
This is very good and it was still good the next day, however I will peel the cucumbers next time
Can you tell me if how long this salad will last, in case there are any leftovers? Thank you.
I don’t recommend overnight. Should just serve and finish it.
