What’s in this Cucumber Onion Salad Recipe?
- Cucumbers: Start with fresh, juicy cucumbers, cut into slices. A mandolin works really well for quick slicing. Thinner or thicker slices work, as do diced or cubed cucumbers. A chopped cucumber and onion salad is great too!
- Red Onion: Red onion has a nice bite that “spices” this salad up. I like cutting them into half moons, but you can chop or dice onions if you prefer.
- Apple Cider Vinegar: This is the base of my vinegar salad dressing. It’s tangy and slightly sweet, and less acidic than some other vinegars, which is perfect for a light salad.
- Sugar: Add just a little bit of granulated sugar into the dressing for sweetness.
- Water: Water fills out the dressing. No oil needed here!

Tips for Success
- Most varieties of cucumbers in North America (English cucumbers and “garden cucumbers” are common) will be fine without peeling. But if you use a variety with thick or bumpy skin, feel free to gently peel them.
- Generously sprinkle salt over the cucumber slices before tossing them into the salad. The salt will draw out extra water and moisture so that they don’t get watery or soggy. You can salt them in a colander to prevent too much salt from accumulating on the slices.
- If the red onion flavor is overpowering, try soaking slices in water before adding them to the salad. I personally love a strong onion taste, but if my husband is eating it too, that’s my favorite trick!
How to Make Ahead and Store
I love that this quick and easy cucumber salad with vinegar dressing can be prepped and/or made ahead of time.
- Veggies: Slice cucumbers and onions ahead of time, and store them in airtight containers (separately) until ready to use. If you do this, I recommend salting the cucumbers so they don’t accumulate moisture. You can also go ahead and soak the onions if you want to cut their intensity.
- Dressing: Combine the vinegar dressing ingredients in a jar as instructed in the recipe card. This can be kept in the fridge for up to 4-5 days. Just shake or stir before tossing into the salad.
Toss everything together when you’re ready to serve it.
Serving Suggestions
This easy cucumber salad is one of my all-time favorite spring and summer salad recipes. I love to serve it for light lunches outside along with grilled chicken breast, garlic butter salmon, or grilled pork chops. It’s also a great side salad for Easter dinner, along with lamb or ham. It really pairs beautifully with so many dishes!

What do you all think about adding thin slices of green olives?
Try it and let us know if it’s tasty!
I think sliced black olives would be a bit better. Green olives have kind of a bite in flavor and may compete with the tangy vinegar.
I lessened the amount of water in the recipe and added more apple cider vinegar to make it more tangy.
Thanks for sharing, Jackie!
Great recipe! Added 2 cloves sliced garlic. Very close to my grandmother’s recipe. Loved it!
Thanks for sharing, William!
This was a really refreshing lunch! I added feta cheese and a few cherry tomatoes as well. Thanks for the recipe!
Thanks for stopping by and sharing, Aimee!
Fussy partner loved it! He’s not generally into veggies, sharp or peppery tastes, but devoured it! It’s easy-peasy, and on our regular meal list now.
Thanks for sharing, Elliot!
Delicious. Never made before ..
for sooth .. Husband loved it and is on his regular request list. I will remember to score or peel cukes next time, but I also enjoy combination of colors.
Thanks for sharing, Liz!
For Sooth. I haven’t heard that phrase in decades. Made Mr.Man look it up. = )
Modify to your liking!
Thank you for being so gracious in the face of such rudeness.
I made this. Yes, it’s yummy and remind me of Japanese Namasu, which also use same ingredients for marinate, usually use daikon radish for vegetable.
That looks delicious!!
This was delicious. I peeled my cucumber and substituted stevia for the sugar and sweet onion for the red onion. I did not put any fresh herbs on it. It was good without them. Maybe would add for company. I will make this again.
Thanks for sharing!
I love the flavor of this recipe and would offer the suggestion to peel the cucumbers first. I found the cucumber peel to be tough and it made it difficult to eat the salad. Or score the peel so just a bit of it remains to provide a bit of color.
Definitely modify to your liking!
