This crisp and refreshing salad combines thinly sliced cucumbers with zesty red onions and fragrant fresh dill, all tossed in a simple tangy-sweet vinaigrette made with apple cider vinegar and olive oil.
The dish comes together in just 15 minutes with no cooking required—simply whisk the dressing, combine with vegetables, and let the flavors meld for at least 10 minutes before serving.
It's an excellent choice for hot summer days, outdoor picnics, or as a light accompaniment to grilled meats and fish. The salad is naturally vegetarian, gluten-free, and low in carbohydrates.
Last July, my kitchen had no air conditioning and I was desperate for something that tasted like a garden breeze. My neighbor dropped off fresh cucumbers from her backyard, and I threw together this salad with whatever was in my crisper drawer. Now it is the only thing I want when the mercury climbs above eighty degrees.
I brought this to a potluck last summer and watched three different people ask for the recipe within ten minutes of arriving. My friend Sarah stood by the bowl practically eating it with a spoon, claiming she was just tasting it for quality control. Now whenever we have a barbecue, this salad shows up on the table with zero prompting from me.
Ingredients
- 2 large cucumbers: English or Persian cucumbers work beautifully here since they have thinner skins and fewer seeds
- 1/2 red onion: The sweetness of red onion balances the vinegar better than white or yellow onions
- 1/4 cup fresh dill: Fresh herbs are non-negotiable here, dried dill will give you a dusty tasting salad
- 3 tablespoons apple cider vinegar: White vinegar works too but apple cider adds a subtle fruitiness
- 1 tablespoon olive oil: Helps the dressing cling to the cucumbers and rounds out the acidity
- 1 teaspoon sugar: Just enough to tame the vinegar bite without making the salad sweet
- 1/2 teaspoon salt: Draws moisture out of the cucumbers for better texture
- 1/4 teaspoon freshly ground black pepper: Freshly cracked makes a noticeable difference here
Instructions
- Prep your vegetables:
- Slice the cucumbers as thin as you possibly can, they should almost be translucent. Cut the red onion into paper thin half moons so they marry well with the delicate cucumber slices.
- Make the dressing:
- Whisk the vinegar, olive oil, sugar, salt, and pepper in a small bowl until the sugar dissolves completely. Give it a taste and adjust the salt if needed.
- Combine everything:
- Toss the cucumbers, onion, and fresh dill in a large bowl. Pour the dressing over the top and use your hands to gently toss until everything is evenly coated.
- Let it rest:
- Let the salad sit for at least ten minutes, giving it a gentle toss halfway through. The cucumbers will release some liquid and the onions will mellow out beautifully.
My grandmother used to make something similar but with heavy sour cream instead of this light vinaigrette. I tried her version once and understood why she loved it, but this lighter preparation has become my go-to for modern potlucks where everyone seems to be watching something in their diet.
Make It Your Own
The beauty of this salad is how easily it adapts to whatever you have on hand or whatever mood you are in. Sometimes I throw in diced bell peppers for color or thin ribbons of carrot for sweetness. The vinegar base plays nicely with almost any crisp vegetable you want to use up.
Serving Suggestions
This salad cuts through rich foods like grilled sausages or braised short ribs. I also love it spooned over a bed of mixed greens for a light lunch or paired with crusty bread and sharp cheese. The acidic crunch makes it perfect alongside anything heavy or warming.
Storage and Make Ahead
This salad keeps well in the refrigerator for up to two days, though the cucumbers will soften as time passes. The flavors actually deepen after a few hours, making it an excellent choice for meal prep or picnic planning.
- If you know you are serving this later, wait to add the fresh dill until right before serving
- Drain off any excess liquid before serving leftovers to keep the texture crisp
- This recipe doubles beautifully for larger gatherings without needing any other adjustments
Sometimes the simplest recipes are the ones that stick around the longest. This cucumber salad has earned its permanent place in my summer rotation, right alongside the grill and the iced tea pitcher.
