Why We Love this Cucumber and Onion Salad

Quick and easy: It takes only a few minutes to make up a batch of this cucumber salad and you just need a few basic ingredients. We make this recipe pretty much on a weekly basis because it’s so easy!
Make ahead: This is the type of salad that tastes better the longer that it sits and absorbs all of those delicious flavours from the dressing. Perfect if you want to get an early start on dinner or for entertaining!
Refreshing: This salad can obviously be enjoyed all year round, but it’s so perfect for the summer. Light, zingy and so refreshing.

Ingredient Notes

Cucumbers: The cucumbers form the refreshing base of the salad. Use English cucumbers for best results. You don’t need to peel them, but you can if you prefer. I find the skin adds some nice contrast in colour to the dish.
Red Onion: Red onion is milder than white or yellow onions and can be enjoyed raw in salads. Slice it thinly so that it’s not overpowering.
Sesame Oil: Sesame oil adds a great Asian flavour to this cucumber salad. In a pinch you can use another neutral oil, but note that the flavour will be different.
Rice Vinegar: Rice vinegar is crisp and tart, though milder than other varieties. Use the unseasoned variety to reduce added sodium and sugar. In a pinch you can substitute it for apple cider vinegar.
Sesame seeds: To garnish. I like to lightly toast them if time allows since it adds a nice flavour, but it’s totally optional.

Step by Step Instructions

Using a sharp knife or mandolin slicer, thinly slice the cucumber.

Add the sliced cucumber and red onion to a large bowl.
Add the sesame oil, rice vinegar, salt and pepper. Toss well to coat.

Let the salad sit for at least 30 minutes to allow the flavours to come together. Garnish with sesame seeds before serving.

Recipe Tips for Quick Cucumber Salad

If you want to get rid of some of the extra water from the cucumbers, place the sliced cucumber in a colander over a bowl or in the sink for 30 minutes prior to adding the cucumber to the salad. Then pat it dry with a paper towel to eliminate excess moisture.
I recommend cutting the cucumber and onions very thinly as the thin slices will more readily absorb the flavours from the dressing. I like to use a mandolin slicer and cut the cucumbers about 1/8-1/4 inch think. You can also use a sharp knife to thinly cut the cucumbers.
Allow the salad to sit in the dressing for at least 30 minutes prior to serving to allow the flavours to intensify. It tends to taste better the longer that it sits.
If the salad has been sitting for a while, toss it well right before serving since the dressing tends to gather in the bottom of the bowl.

Recipe FAQs

How to store

You can store this cucumber salad in the fridge in a covered bowl or air-tight container for up to three days. The cucumber may release some water and some of the dressing may sink to the bottom so give it a good toss to combine before serving.

How do you toast sesame seeds?

You can add raw sesame seeds to garnish the salad, but toasting them releases their oils and helps bring out that nutty flavour.

To toast: Place them on a lined baking sheet and place in a preheated oven set to 350F. Bake for around 10 minutes, stirring occasionally until golden brown.
