This cucumber radish salad delivers the perfect crisp, refreshing bite when summer temperatures soar. The combination of cool cucumbers and peppery radishes creates a light yet satisfying side dish that pairs beautifully with grilled meats or can stand alone as a healthy snack.
This salad has become my warm-weather staple for everything from backyard barbecues to quick weekday lunches. I started making it years ago when my garden produced more cucumbers than I knew what to do with, and it's remained in my regular rotation ever since.
Key Ingredients
- Persian cucumbers: Offering the perfect crunch and thin skin that requires no peeling
- Fresh radishes: Providing a peppery bite and gorgeous color contrast
- Green onions: Adding mild onion flavor without overpowering the delicate vegetables
- Fresh dill: Bringing bright herbaceous notes that complement the cucumbers perfectly
- Olive oil: Creating the base for the simple dressing. Look for extra virgin for best flavor
- Fresh lemon juice: Adding necessary acidity to balance the vegetables
- Kosher salt: Enhancing all the flavors. Choose flaky sea salt for finishing if available
- Black pepper: Adding subtle warmth. Freshly ground makes a noticeable difference
Step-by-Step Instructions
- Slice the vegetables:
- Using a sharp knife or mandoline slicer cut cucumbers and radishes into thin uniform rounds about 1/8 inch thick. For best results use a mandoline which creates perfectly even slices quickly. The thin slices allow the dressing to better penetrate the vegetables.
- Make the dressing:
- Combine olive oil lemon juice salt and pepper in a small bowl. Whisk thoroughly until emulsified ensuring the oil and acid are well combined. This simple dressing lets the vegetables shine while adding just enough flavor enhancement.
- Combine and toss:
- Add all sliced vegetables green onions and fresh dill to a medium mixing bowl. Pour dressing over top and gently toss until every piece is lightly coated. Be careful not to overmix which can bruise the delicate herbs and vegetables.
- Serve and garnish:
- Transfer the finished salad to a serving bowl and finish with an extra sprinkle of salt and pepper if desired. This final seasoning brightens the flavor and adds visual appeal to the dish just before serving.

Fresh dill is what truly makes this salad special in my kitchen. While many herbs work well here the feathery texture and bright anise notes of dill complement the cucumber in a way that reminds me of summers at my grandmother's table. She always had a patch of dill growing by her kitchen door specifically for cucumber salads.
Make Ahead and Storage
This cucumber radish salad can be prepared up to 24 hours in advance making it perfect for meal prep or entertaining. The vegetables will release some liquid as they sit which actually enhances the flavor profile creating a light brine. For best texture store in an airtight container in the refrigerator and give it a quick toss before serving to redistribute the dressing.
Ingredient Substitutions
If Persian cucumbers aren't available English cucumbers make an excellent alternative as they also have thin edible skin and fewer seeds than regular garden cucumbers. For a different flavor profile try substituting mint or basil for the dill. Lime juice works wonderfully in place of lemon juice offering a slightly different citrus note. For added richness consider including avocado just before serving.
Serving Suggestions
This versatile salad shines as a side dish alongside grilled chicken salmon or lamb. It also makes a wonderful addition to Mediterranean mezze platters alongside hummus and pita. For a more substantial meal top the salad with crumbled feta cheese and a sprinkle of toasted pine nuts. During hot summer days I often enjoy a larger portion as a light lunch with a slice of crusty bread.
Cultural Context
This simple preparation of cucumbers and radishes has roots in many culinary traditions particularly those of Eastern Europe and the Mediterranean where cool fresh salads provide relief during hot weather. In Polish cuisine a similar combination is served with sour cream while Greek versions might include olives and feta. The simplicity of this dish showcases the vegetables at their peak allowing their natural flavors to shine.
