This cucumber dill salad is a no-cook side that comes together in 15 minutes: sliced cucumbers, sweet onion, and cherry tomatoes tossed in a Greek yogurt dressing with fresh dill and parsley. The honest reason to make it is that it works — it’s light, it’s fast, and it actually gets better after 30 minutes in the fridge, which means you can make it before dinner and forget about it.
The technique that matters
The one thing that separates a good version of this salad from a watery, bland one is how you handle the cucumbers before they go in the bowl. Cucumbers hold a lot of water, and once you slice them and add dressing, that water comes out and dilutes everything. Salting the slices and letting them sit in a colander for 10 minutes pulls out most of that moisture before it becomes your problem. Pat them dry with a paper towel afterward — don’t skip this step. The second technique worth getting right is slicing the onion as thin as you can manage. A thick piece of raw onion will dominate every bite; a thin one softens into the background and lets the dill do its job.
Smart swaps
- Greek yogurt: Non-fat works fine and keeps the calories low (58 kcal per serving). Full-fat Greek yogurt makes the dressing noticeably richer if that’s what you’re after. Sour cream works too. For dairy-free, a plain coconut or cashew yogurt will hold the dressing together, though the flavor will be slightly different.
- White vinegar: Any mild acid works here — white wine vinegar, apple cider vinegar, or fresh lemon juice. Lemon juice gives the brightest result in summer.
- Fresh dill: This is the one ingredient worth buying fresh rather than dried. Dried dill loses most of its flavor and the salad will taste flat. If fresh dill genuinely isn’t available, fresh mint is a reasonable substitute — different, but still good.
If something goes sideways
- The dressing looks too thick when you mix it: That’s normal. The cucumbers release moisture as the salad chills, which loosens the dressing naturally. Don’t add water or extra vinegar before refrigerating.
- The salad tastes bland straight out of the fridge: Cold mutes flavor. Taste it again after it’s sat at room temperature for 5 minutes, then adjust salt. A small extra splash of vinegar also wakes it up quickly.
- The onion flavor is too sharp: Soak the sliced onion in cold water for 10 minutes before adding it to the bowl. Drain and pat dry. This takes the edge off raw onion without losing the texture.
- The tomatoes are making the bowl watery: Cherry tomatoes release juice once sliced. If you’re making this more than an hour ahead, add the tomatoes right before serving instead of during the initial mix.
- The dressing isn’t sticking to the cucumbers: This usually means the cucumbers weren’t dried well enough after salting. More surface moisture = dressing slides right off. Next time, press the paper towel firmly against the slices.
Storage and reheating
Store leftovers in an airtight container in the fridge and eat them within 24 hours. After that, the cucumbers keep releasing water and the texture turns soft and soggy — it’s still safe to eat, but not enjoyable. There’s no reheating involved since this is a cold salad. Freezing isn’t an option; cucumbers turn mushy when frozen and thawed. Skip the garnish of extra dill and green onions until you’re ready to serve — not worth dressing up a bowl that’s going straight back into the fridge.

Your questions, answered
Do I have to salt the cucumbers first, or can I skip it?
You can skip it, but the dressing will likely turn watery within 20 minutes of mixing. Salting and draining the cucumber slices for 10 minutes before you start is the single most effective thing you can do to keep the texture right.
Can I make this salad the night before?
It’s better made the same day. The salad is at its best between 30 minutes and a few hours after mixing — the flavors have melded but the cucumbers are still firm. By the next morning, the texture will have softened noticeably.
Can I use regular yogurt instead of Greek yogurt?
Regular yogurt is too thin and will make the dressing runny. Greek yogurt works because it’s been strained to a thicker consistency. If Greek yogurt isn’t available, strained regular yogurt or sour cream are the closest substitutes.
What can I serve this with?
It works well alongside grilled chicken, fish, or anything off the grill. It’s also good with warm pita or a simple piece of crusty bread if you want to keep the meal light.
