Fresh Marinated Cucumber and Onion Salad

A quick and easy 5-minute summer side dish featuring crisp cucumbers and sharp onions marinated in a tangy, slightly sweet vinegar dressing with fresh dill.

Ingredients

Scale
  • 3 medium cucumbers, thinly sliced (Kirby or English cucumbers)
  • 1 medium red onion, thinly sliced
  • 1/2 cup (120 ml) white vinegar
  • 2 tablespoons sugar
  • 1 teaspoon salt
  • 2 tablespoons fresh dill, chopped (optional)
  • A pinch of freshly cracked black pepper
  • 1/2 cup (120 ml) water

Instructions

  1. Wash and dry the cucumbers. Using a sharp knife or mandoline, slice the cucumbers into thin rounds, about 1/8-inch (3 mm) thick.
  2. Peel and thinly slice the red onion into half-moons, aiming for similar thickness to the cucumbers. This usually takes about 10 minutes.
  3. In a mixing bowl, whisk together 1/2 cup white vinegar, 1/2 cup water, 2 tablespoons sugar, 1 teaspoon salt, and a pinch of freshly cracked black pepper until the sugar and salt dissolve (1–2 minutes). Stir in 2 tablespoons chopped fresh dill if using.
  4. Add the sliced cucumbers and onions to the bowl with the marinade. Toss gently but thoroughly to coat every slice (about 2 minutes).
  5. Transfer the salad to a glass storage container or cover the bowl tightly with plastic wrap. Refrigerate for at least 30 minutes, ideally 1 to 2 hours.
  6. Before serving, give the salad a quick stir. Taste and adjust seasoning if needed. Serve chilled.

Notes

Soak sliced onions in cold water for 10 minutes before mixing to mellow sharpness. Use a mandoline slicer for even thin slices to help marinade absorption. Marinate at least 30 minutes for best flavor; up to 24 hours is possible but cucumbers soften more. Adjust sugar and vinegar to taste. Optional additions include jalapeño slices, celery seed, or swapping herbs like mint or basil.
