Variations
This fresh salad is so easy to customize! Try adding halved cherry tomatoes for a pop of color, or thinly sliced bell peppers for extra crunch. Love herbs? Fresh dill pairs wonderfully with cucumbers – just sprinkle some on top before serving.
You can also swap the white vinegar for rice vinegar or apple cider vinegar to change up the flavor profile.
Serving Suggestions
This cool and crisp salad makes a perfect side dish for summer barbecues! Serve it alongside grilled meats, sandwiches, or bring it to your next picnic. It’s also great with spicy dishes since the cucumbers help cool things down. For a pretty presentation, try serving it in a clear glass bowl so everyone can see the lovely layers of vegetables.
Storage Tips
Keep your cucumber salad fresh in an airtight container in the fridge for up to 3 days. The vegetables will continue to soften and the flavors will get stronger over time.
If you want to make it ahead, you can slice the vegetables and mix the dressing separately, then combine them about an hour before serving. This gives you the perfect texture and taste!
