  • knife


  • 3 medium cucumbers
  • ½ small red onion
  • ¾ cup champagne or white wine vinegar SEE NOTE
  • ¼ cup water
  • 2 tablespoon lemon juice
  • ½ teaspoon sugar add more if the dressing tastes to acidic for your taste
  • Salt and pepper to taste


  • Wash and dry the cucumbers and with a vegetable peeler, peel stripes into the cucumber.
  • This is optional. You can also peel all of it (it won’t be as crisp) or none of it. Thinly slice the cucumber and place in a large bowl.
  • Peel the onion and cut it in half and thinly slice half of the onion and put it in the bowl with the cucumber.
  • Whisk the ¾ cups vinegar, ¼ cup water, 2 tablespoon lemon juice, ½ teaspoon sugar, and salt and pepper until fully combined.
  • Pour the dressing over the cucumber slices and onion and toss to coat. Cover and refrigerate for approximately an hour to chill.
  • Enjoy!


We love using champagne or white wine vinegar.
It has a lighter, more delicate flavor than other white vinegars, so it doesn’t overpower the beautiful freshness of the cucumbers.
You can use apple cider vinegar if you want a fruitier dressing or distilled white vinegar if you don’t mind a more acidic and sharp dressing.
