Cucumber Onion Salad

This light and refreshing salad is a classic summer side dish!
Prep Time 10 minutes
Total Time 10 minutes
Servings 4


  • 3 cups thinly sliced English cucumbers approximately 1 ½ to 2 cucumbers
  • 1 cup thinly sliced red onion or sweet white onion
  • ½ cup apple cider vinegar
  • ¼ cup water
  • 1 teaspoon salt more or less, to taste
  • ½ teaspoon black pepper more or less, to taste
  • 1 tablespoon granulated white sugar more or less, to taste
  • 1 tablespoon chopped fresh dill


  • Toss the sliced cucumbers and onion in a large bowl.
  • Whisk together vinegar, water, salt, pepper and sugar in a small bowl.
  • Drizzle vinegar mixture over cucumbers and onions and toss to coat as evenly as possible. Sprinkle with fresh dill. Cover and refrigerate until ready to serve.


  • I prefer this served within a few hours of preparing, but it can be made ahead and served up to 24 hours after preparing.
