🛒 Ingredients and substitutions
You'll find a complete list of ingredients with amounts in the recipe card below. But before we get to the full recipe, here are a few notes about some of the ingredients.
- cucumber (Long English): use one or two, depending on their size
- red onion: if you find your onion is too strong, soak the slices in cool water for 10 to 15 minutes then drain.
- fresh mint leaves
And for the spicy Thai dressing, you'll need
- rice wine vinegar: This vinegar has a mild flavour and acidity, ideal for a light Thai salad like this one. Apple cider vinegar would be much too strong for this recipe. Check your label: "seasoned" rice vinegar has both sugar and salt added and wil change the flavour of this dressing considerably.
- sesame oil: regular sesame oil. If you only have toasted sesame oil on hand, use half the amount and increase the amount of olive oil accordingly.
- olive oil
- sweet Thai red chili sauce: adds both sweetness and heat! (affiliate link)
- Slice the cucumbers very thinly (no need to peel them). A mandolin works well for this job. You could also use a sharp knife or a spiralizer if you'd like.
- Next, slice the red onions thinly, leave them in rings, or chopped them finely, you do you!
- Give the mint leaves a rough chop.
- Combine the cucumber slices, onion slices and mint leaves in a small bowl.
- Whisk the dressing ingredients together, then toss with the salad and serve!
🔁 Possible Variations
Like a little crunch to your salad? Garnish your Thai cucumber salad with ¼ cup of finely chopped peanuts.
Like more heat? Add a sprinkling of dried red chili flakes, or a very small amount of finely chopped dried Thai red chili. These are very hot, so start with a tiny amount. You can always add more, but you can't take them away!
