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!

can we use white onions instead of red?
Yes, it will just change the taste a bit.

This cucumber salad is excellent, it tastes like health salad which is why I added sliced carrots and celery. The cucumbers I used are from my daughter’s garden so I peeled and deceded them. Sooo yummy!!!
Recipe is very good, but liquid part needs to be tripled.
I absolutely love this and have made it several times. It’s refreshing and delicious! Thank you for this.
This is good stuff Maynard. I enjoy cooking and every time I need a recipe I’m here. Works for me every time.
I use “Maynard” too when I say something is good…. Where does that come from??

It comes from a Malt-O-Meal commercial in the early 80’s
Thank you! My mom use to make this when we were kids and it works great for a snack on my diet. I just use stevia instead of sugar.
Very easy to make an sooo delicious. Was looking for something a little more healthy as I usually make with vinegar and mayo
Can I add tomatoes to this salad and what if I don’t like onions. I do like to cook with dried minced onions. Would it be possible to mix some of them in with the dressing and let them soak before mixing it with the salad?
Hi Janie, yes, you can absolutely add tomatoes! We have not experimented with adding dried minced onions to the dressing, but we think it could work!
I have made this but heated the sugar water then sprinkled crushed dill over and poured liquid and everyone goes crazy over it
