Ingredients
- 2 medium cucumbers (approx. 400g), thinly sliced
- 1 pint (approx. 300g) cherry or grape tomatoes, halved
- 1 small red or white onion (approx. 100g), very thinly sliced
- 60 ml (1/4 cup) apple cider vinegar or red wine vinegar
- 30 ml (2 tbsp) extra virgin olive oil
- 1 large clove garlic, finely minced
- 15 ml (1 tbsp) freshly chopped parsley or dill
- 5 ml (1 tsp) sea salt, or to taste
- 2.5 ml (1/2 tsp) freshly ground black pepper, or to taste
- Optional: 2.5 ml (1/2 tsp) red pepper flakes for a touch of heat
Instructions
- Begin by meticulously washing all fresh produce. Use a sharp knife or mandoline to thinly slice the cucumbers into uniform rounds or half-moons. Halve the cherry or grape tomatoes lengthwise. Peel and very thinly slice the red or white onion; for a milder flavor, you can rinse the onion slices under cold water for a few minutes and pat them dry.
- In a medium-sized mixing bowl, prepare the vibrant marinade. Whisk together the apple cider vinegar (or red wine vinegar), extra virgin olive oil, finely minced garlic, sea salt, freshly ground black pepper, and the optional red pepper flakes until well combined and slightly emulsified.
- In a large bowl, gently combine the prepared sliced cucumbers, halved tomatoes, and thinly sliced onions. Ensure there's ample space to toss without crushing the delicate vegetables.
- Pour the prepared marinade evenly over the vegetable mixture. Using tongs or a large spoon, gently toss the vegetables until every piece is thoroughly coated in the flavorful dressing. This ensures maximum flavor absorption.
- Cover the bowl tightly with plastic wrap and refrigerate for a minimum of 30 minutes. This crucial chilling period allows the flavors to meld and the vegetables to slightly tenderize and absorb the marinade, resulting in a more profound taste. For optimal flavor, you can chill for up to 2 hours.
- Just before serving, stir in the freshly chopped parsley or dill. Taste and adjust seasoning if necessary, adding a little more salt or pepper if desired. Serve chilled as a refreshing side dish.

Essential Success Tips
- Use the freshest possible vegetables. Crisp cucumbers and ripe, firm tomatoes will make a significant difference in taste and texture.
- Slice your onions very thinly. A mandoline can achieve this perfectly, ensuring they integrate beautifully without being overpowering.
- Don't skip the chilling step! Marination allows the flavors to deepen and the vinegar to slightly tenderize the vegetables, enhancing the overall experience.
- Taste and adjust seasoning before serving. Different vegetables and vinegars can vary in intensity, so a final check ensures perfect balance.
- For best results, consume the dish within 24-48 hours. While it can last longer, the vegetables might soften too much over time.
Professional Cooking Secrets
- To reduce the sharp bite of raw red onion, slice it thinly and then soak the slices in ice water for 10-15 minutes before draining and drying. This mellows their flavor considerably.
- Consider adding a tiny pinch of sugar (e.g., 2-3g or 1/2 tsp) to the marinade. It won't make the dish sweet, but it will balance the acidity of the vinegar, making the overall flavor profile more rounded and harmonious.
- Experiment with different vinegars. While apple cider or red wine vinegar are classics, a high-quality white balsamic vinegar can add a delicate sweetness and complexity, or even a touch of rice vinegar for an Asian-inspired twist.
Notes
- This salad is best enjoyed chilled. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days, though the vegetables may soften further.
- For a creamier texture, stir in a spoonful of Greek yogurt or sour cream into the dressing right before serving.
- Add other vegetables like thinly sliced bell peppers or finely diced celery for extra crunch and color.
Frequently Asked Questions
Can I make this salad ahead of time for a party?
Yes, you can prepare the vegetables and the marinade up to 24 hours in advance. Combine them and chill for a minimum of 30 minutes, but for best texture, add the fresh herbs and serve within 2-4 hours of combining.
What kind of cucumbers are best for this recipe?
English cucumbers (hothouse) or Persian cucumbers are ideal because they have fewer seeds and thinner skins, eliminating the need for peeling and resulting in a crispier texture. Regular garden cucumbers work too, but you might want to peel them and scoop out the seeds if they are large.
How can I make this dish more substantial?
To make it a more filling meal, consider adding crumbled feta cheese, cubed avocado, grilled chicken strips, chickpeas, or cooked quinoa.
