When I want to make a quick and easy side dish, especially in the Summer, I always turn to this zesty cucumber onion salad. This cucumber salad recipe comes together quickly and easily with just a few ingredients. Fresh cucumber and red onion slices are dressed simply in a homemade vinegar salad dressing. It’s a flavor combination that makes me think of beautiful weather, family get-togethers, and fun around the table.
I have a neighbor that always brings over home grown cucumbers, and that leads to us sharing a plate of this delicious salad! All you need are fresh veggies and some pantry staples to make a simple vinegar dressing.
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!

I am also mostly a noncooker… It can be difficult to put everything together at the same time.
The is the very recipe I was looking for! I’m so glad I live in this day and age when information is so easy to come by.
Thanks so much for stopping by, Loretta!
Sounds like it will be a good recipe. Thanks!!!!!
We hope you love it, Carol!
I’m making this for lunch today for about the 10th time. This is a fantastic recipe now in my regular lunchtime favorites rotation. Thank you!
I liked the salad but I like it to be vinegar forward so I added more vinegar. Next time I will use half the water.
Thanks for sharing what worked for you, Debby!
Pepper is definitely an ingredient that is up to personal taste! Feel free to reduce the amount!
We’re so sorry to hear that, Lee! There are ads, but they shouldn’t cover the recipe!
The recipe in my collection used 1/2 cup sugar. My partner is diabetic so looking for a recipe with less . Your recipe delicious. Thank you!
Thank you! My wife usually makes this for us, but she wasn’t home so I google a recipe. Super simple, easy, and my 3 year old ate a whole cucumber by himself.
My family loved this as a side dish to hamburgers. Yum!
