This is my go-to cucumber salad for summer picnics and BBQs. It’s simple, irresistibly good, and actually gets better if you make it ahead—what more could you ask for? I like to use English cucumbers (also called seedless, European, burpless, or hothouse cucumbers). They’re typically wrapped in plastic instead of waxed, so there’s no need to peel them, and they’re slightly sweeter with fewer seeds than regular cucumbers. And the best part? The red onion softens and lightly pickles in the dressing, adding just the right tangy bite.
If you’re in the mood for something creamier, try my creamy cucumber salad—it’s just as delicious, with a sour cream and mayonnaise-based dressing.
What You’ll Need to Make The Best Cucumber Salad
Jennifer Segal
Cucumbers and Red Onion: English (or hothouse cucumbers) are ideal. Persian cucumbers work too; they’re a bit crisper and smaller, so you’ll need a few more. The onion lends sharpness and crunch, and once it sits in the dressing, it takes on a lightly pickled flavor.
Salt, Sugar, and Pepper: Salt draws out excess moisture from the cucumbers and brings out their flavor. A touch of sugar balances the tang of the vinegar, and freshly ground black pepper adds a subtle kick.
Vinegar and Oil: White wine vinegar gives the dressing its bright, tangy backbone. I use a mix of olive oil for richness and vegetable oil to keep the flavor smooth and balanced—but feel free to use all of one or the other if that’s what you have on hand.
Fresh Herbs: Mint gives the salad a refreshing lift and pairs beautifully with the sweet-tangy dressing, but fresh dill (or another soft herb) works just as well if that’s what you have on hand.
Step-by-Step Instructions
Step 1: Prep the cucumbers. Start by slicing the cucumbers in half lengthwise, then use a small spoon to gently scrape out the seeds—this helps keep the salad from getting watery. Slice the cucumbers thinly using a sharp knife or a mandoline if you have one. Place them in a colander set over the sink, sprinkle with the salt, and toss to coat.

Step 2: Let them drain. Let the salted cucumbers sit for about 30 minutes. They’ll release a lot of water during this time, which keeps the salad nice and crisp and prevents the dressing from thinning out. When the time’s up, tap the colander against the sink to shake off any lingering moisture, then transfer the cucumbers to a clean dish towel and blot them dry as best you can.

Step 3: Temper the onions (optional). If you’re sensitive to raw onion, you can soak the sliced red onions in a bowl of ice water for about 10 minutes. It really helps tame the sharpness. Drain them well and pat dry with a paper towel. (Totally optional—if you like raw onions, skip this step.)

Step 4: Mix it all together. In a large bowl, combine the drained cucumbers, onions, chopped mint (or whatever fresh herb you’re using), vinegar, both oils, sugar, and pepper. Give everything a good toss to coat. Cover the bowl and refrigerate the salad for at least 20 minutes or up to 12 hours ahead before serving to let the flavors come together. Serve it cold—it’s the perfect make-ahead side dish for any summer meal!
