You can't beat a salad with great crunch and a tasty dressing. This Thai cucumber salad has all of that. Plus, it is quick and easy to make! This recipe comes with courtesy of my lifelong friend who was introduced to it years ago in a Thai cooking class she took in Australia (thanks to the instructor, Chanin Somboonsook).

I made a few changes over the years to suit our tastebuds, toning down the fish sauce flavor of the dressing, swapping sugar with agave nectar and using half of the raw red onion. Feel free to make adjustments to suit your palate.

This salad is a fantastic accompaniment to Pad Thai or Thai-inspired red curry. It's bright, refreshing flavors complement richer dishes beautifully.

Tips for making this recipe

Feel free to use more red onion, if you prefer. I find that raw onion tends to overwhelm the other flavors, so I stick to ¼ onion.
If you're sensitive to spice, feel free to leave out the red chili pepper/red pepper flakes.
This salad is best when served right after being tossed with the dressing. The cucumbers will be at peak crispness!

Ingredients and substitutions

Cucumber: Use an English cucumber for this recipe. There's no need to peel it or remove the seeds.
Onion: A quarter to a half of a small red onion, depending on how much you like raw onion.
Chile: Use a portion of a small red chile, seeds and membranes removed. I used a red jalapeño pepper. Red chile flakes can be substituted.
Cilantro: Mince some fresh cilantro.
Peanuts: I used roasted, salted peanuts.
Dressing: The dressing is a combination of unseasoned rice vinegar, fish sauce and agave nectar. Honey can be substituted for the agave nectar. If you prefer to use granulated sugar, stir or whisk the dressing until the sugar dissolves.

How to make Thai cucumber salad

Prep the veggies: Cut the cucumber in half lengthwise, then cut into ¼-inch thick slices. Peel the half or quarter red onion, depending on how much you like red onion, and slice thinly. Combine the cucumber and onion in a bowl.
Make the dressing: In a small bowl, whisk together the rice vinegar, fish sauce and agave nectar. Stir in the minced red chile or chile flakes, if using.
Toss: Toss the cucumber and onion with the dressing. Add most of the minced cilantro and peanuts and toss again.
Garnish and serve: Garnish with the remaining cilantro and peanuts. Serve it up or cover and refrigerate for up to 24 hours.

Make-ahead and storage

Make-ahead: If making this salad ahead of time, I highly recommend storing the cucumber and onion separately from the dressing. Right before serving, toss the veggies with the cilantro, peanuts and dressing. This ensures crispy cucumbers!

Leftovers: Leftovers can be stored up for up to 24 hours. Store them in an airtight container in the refrigerator. After 24 hours, the cucumbers tend to soften.

Frequently Asked Questions

How can I make this salad vegan?

If you prefer a vegan salad, substitute the fish sauce with soy sauce. And be sure to use agave nectar or sugar in the dressing - not honey - to keep it vegan.

What can I use instead of cilantro?

If you're not a cilantro fan, substitute with a combination minced Italian parsley and fresh mint.
