Holly’s Recipe Highlights

  • Flavor: Light, crisp, and refreshing with a tangy vinaigrette, fresh herbs, and just the right amount of peppery bite.
  • Skill Level: This simple, no cook recipe is perfect for beginners or seasoned chefs.
  • Tools: Use a large bowl to whisk the dressing and toss with the veggies. A mandoline makes quick work of slicing the cucumber, radishes, and even the onions, but a sharp knife would work for this too. 
  • Time-Saving Tip: Slice the vegetables ahead of time then toss with dressing just before chilling.
  • Serving Suggestions: It’s the perfect low-carb side to go with grilled chicken, salmon, burgers, or a simple lunch plate.

Simple Salad Ingredients

  • Cucumbers: English cucumbers stay crisp thanks to their thin skins and fewer seeds. Mini cucumbers add extra crunch and make the best bite-sized rounds.
  • Radishes: Use any variety as long as they are fresh and firm with bright color. Sliced thinly, they help the peppery bite blend into the salad and will soften as they marinate in the dressing.
  • Red Onion: Thin slices add a pop of color and a sharp, zesty bite. Dice for a milder flavor that blends more evenly throughout the salad.
  • Vinaigrette:
    • Fresh dill adds a vibrant, fresh taste. Dried dill can be used but sparingly because it has such concentrated flavor.
    • Olive oil provides a smooth, light base for the dressing. Stick with a mild oil so it doesn’t overshadow the dill and vinegar.
    • White wine vinegar brings a clean and refreshing acidity for a bright and balanced salad.
    • Add salt and pepper before chilling, then taste and adjust before serving since cucumbers naturally release water over time

Variations

  • Regular cucumbers can be used after scrubbing the wax off the outside. Remove any tough seeds peel in needed.
  • Swap red onion with sweet white onions or even sliced green onions for a milder flavor.
  • Apple cider vinegar or lemon juice are lighter, fruit-forward alternatives for white wine vinegar.
  • Stir in a spoonful of sour cream or Greek yogurt for a rich, creamy twist.
  • For a herb forward salad, add parsley, chives, or mint with the dill.
  • Add feta, bocconcini, shaved parmesan, Cotjita, or grilled Halloumi.

Crunchy Salad Secrets

  • Soak the red onion in cold water for 10 minutes, then drain well for a milder onion flavor.
  • Chill and rest the salad before serving to help the dill and vinegar flavor the vegetables.
  • Give everything a final toss before serving for the best flavor.
  • Adjust seasoning after it has chilled.
  • Add in extras like feta, sour cream, or Greek yogurt right before serving for the best salad texture.
  • Use any leftover vinaigrette as a marinade for baked fish, chicken, or shrimp kabobs.

Keep It Fresh

  • Refrigerate leftover cucumber radish salad in an airtight container for up to 5 days. For the crispest texture, enjoy it within the first 2 days.
  • Freezing is not recommended for dishes made with raw vegetables.
