Holly’s Ingredient Tips
- Cucumber: Any cucumber will do, but my preference is either Persian cucumbers, which are about 5 to 6 inches long, or English cucumbers. Both of these varieties have thin skins, a sweeter taste, and smaller seeds. If using field cucumbers, I like to peel them first.
- Dill: Fresh dill has the best flavor, but it can be replaced with dried. Add other fresh herbs, such as chopped parsley or fresh basil.
- Onion: I use a sweet onion in this recipe. You can use a red onion for a bit more bite, or a green onion for a milder flavor.
- Vinegar: Vinegar adds a fresh tang – use either white vinegar, apple cider vinegar, or white wine vinegar.

For the Best Flavor
This cucumber salad recipe features a tangy vinegar dressing; let it marinate in the refrigerator so the flavors blend and the dressing mellows out a bit.
Storing Leftovers
Cucumber salad can be made in advance and will keep for 2-3 days. I like to add a little bit of fresh dill when serving. Leftovers make a great topper for burgers or fish tacos.
