Our Cucumber Onion Salad has crisp cucumbers and sweet onion tossed in a tangy vinegar marinade that gets better the longer it sits. It takes just 10 minutes to throw together, making it the perfect make-ahead recipe for BBQs, potlucks, and summer gatherings.
Every Generation Loves a Good Cucumber Onion Salad.
This Cucumber Onion was a staple of my childhood, just as it was for my mom, and her mom. Probably because it pairs well with literally everything off the grill, and it takes 10 minutes to make. The longer it sits in that tangy marinade, the better it gets, so I almost always make it a few hours ahead and let the fridge do the work for me.
Pro Tips: I recommend English (hothouse) or Persian cucumbers (because of their thin, non-waxy skins and small seeds) and you can choose to peel them or not! For onionsI always use either sweet Visalia onions, or red onions if you want a slightly more peppery bite.
Try my other side dishes, like Baked Beans, Broccoli Apple Salad, Cauliflower Salad, Orzo Salad, Watermelon Salad, and Frog Eye Salad!
How to make Cucumber Salad:

I just took this to a church dinner. Two ladies asked for the recipe which I had tripled. Anywhere I take this, it is a hit. It seems that with so few ingredients it wouldn’t be so good. The only thing I leave out is the pepper. I don’t like the black specs. Last time I used red onion sliced thin and soaked in ice water.
Can I use just plain Vinegar, since I don’t have red wine vinegar?
Yes you can!
