How to Make Thai Cucumber Salad

** You can find the full recipe ingredients and instructions on the printable recipe card below.

Slice the cucumbers thinly
Use a sharp knife or mandoline for even slices. Thin slices absorb the dressing better.
Prepare the dressing
In a bowl, whisk [paid link] together rice vinegar, sugar, and salt until fully dissolved.
Add the vegetables
Toss sliced cucumbers and red onion into the dressing.
Let it sit briefly
Allow the salad to rest for 5 to 10 minutes so the flavors meld and the cucumbers slightly soften.
Finish with herbs and toppings
Add chopped cilantro, crushed peanuts, and optional chili before serving.

Recipe Tips

Slice cucumbers evenly for a consistent texture
Use English or Persian cucumbers for fewer seeds and better crunch
Chill before serving for extra refreshment
Add peanuts just before serving to keep them crisp

Substitutions and Variations

Swap rice vinegar with white vinegar in a pinch
Use honey instead of sugar for a natural sweetener
Add shredded carrots for extra color and crunch
Try mint instead of cilantro for a different herbal note
Make it spicy with fresh Thai chilies or chili oil

What Can Go Wrong (and how to fix it)

Too watery – Cucumbers release water over time. Fix by serving shortly after mixing or salting and draining cucumbers first
Too sour – Add a small amount of sugar to rebalance
Too sweet – Add a splash of vinegar to sharpen the flavor
Bland flavor – Increase salt slightly or add more fresh herbs
Soggy texture – Avoid over-marinating; serve within 30 minutes for best crunch
