Ingredients
- 400g (2 cups) English cucumber, thinly sliced
- 225g (1 1/2 cups) cherry or grape tomatoes, halved
- 100g (1 small) red onion, very thinly sliced
- 60ml (1/4 cup) apple cider vinegar
- 30ml (2 tablespoons) extra virgin olive oil
- 15g (1 tablespoon) granulated sugar or 1 tablespoon honey
- 5g (1 teaspoon) fine sea salt
- 1g (1/4 teaspoon) freshly ground black pepper
- 2g (1/2 teaspoon) dried oregano or Italian seasoning blend
- 10g (2 tablespoons) fresh parsley or dill, finely chopped (for garnish)
Instructions
- Prepare the Vegetables. In a large mixing bowl, gently combine the thinly sliced English cucumber, halved cherry or grape tomatoes, and finely sliced red onion. Ensure the vegetables are evenly distributed, as this will allow for a more consistent marination. Slicing the cucumber thinly ensures it absorbs the marinade well, while halving the tomatoes exposes more surface area for flavor.
- Make the Marinade. In a separate small bowl or a jar with a tight-fitting lid, whisk together the apple cider vinegar, extra virgin olive oil, granulated sugar (or honey), fine sea salt, freshly ground black pepper, and dried oregano or Italian seasoning blend. Whisk vigorously until the sugar dissolves completely and the mixture is well blended and slightly emulsified. The sugar balances the acidity of the vinegar, creating a perfectly rounded dressing.
- Toss the Salad. Pour the freshly prepared marinade evenly over the mixed vegetables in the large bowl. Using a large spoon or salad tongs, gently but thoroughly toss the salad. Ensure every piece of cucumber, tomato, and onion is coated with the vibrant dressing. This critical step ensures maximum flavor infusion throughout the dish.
- Marinate. Cover the bowl tightly with plastic wrap or transfer the entire salad into an airtight container. Refrigerate the salad for a minimum of 30 minutes, and ideally up to 2 hours. During this marination period, stir the salad gently once or twice to redistribute the marinade and ensure all vegetables soak up the delicious flavors. This resting time allows the vegetables to tenderize slightly and fully absorb the tangy dressing.
- Garnish and Serve. Just before bringing the salad to the table, sprinkle the finely chopped fresh parsley or dill generously over the top. This not only adds a beautiful pop of color but also introduces a fresh, herbaceous aroma and flavor that perfectly complements the tangy marinated vegetables. Serve chilled as a refreshing side dish.

Essential Success Tips
- For the best texture, slice the cucumber and red onion very thinly. A mandoline slicer can achieve uniform thinness quickly and safely.
- Don't over-marinate the salad; 30 minutes to 2 hours is ideal. Beyond that, the vegetables can become too soft and lose their crispness, especially the cucumber.
- Taste the marinade before adding it to the vegetables and adjust seasoning (sugar, salt, pepper) to your preference. The balance of sweet and tangy is key.
- Use high-quality fresh produce. The flavor of this simple salad heavily relies on the quality and ripeness of the cucumbers, tomatoes, and onion.
- Chill the serving bowl before tossing the garnished salad for an extra refreshing experience.
Professional Cooking Secrets
- To reduce the harshness of the red onion, slice it thinly and then soak it in ice water for 10-15 minutes before adding to the salad. Pat dry thoroughly.
- For an extra layer of complexity, infuse your olive oil with a crushed garlic clove for an hour before making the marinade, then strain it out.
- Consider adding a pinch of red pepper flakes to the marinade for a subtle kick, or a dash of celery seed for an unexpected layer of flavor that complements the vegetables beautifully.
Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 2-3 days, though the vegetables will soften over time.
- Variations: Feel free to add other fresh vegetables like bell peppers or zucchini. A crumbled feta cheese topping or a few olives can also be a delightful addition.
- Serving Suggestion: This salad is an excellent accompaniment to grilled chicken, fish, or pork. It also shines as a vibrant side for picnics and potlucks.
Frequently Asked Questions
Can I make this salad ahead of time?
Yes, you can prepare the salad up to 2 hours in advance to allow for proper marination. For optimal freshness and texture, avoid making it more than a few hours ahead, as the vegetables, especially the cucumber, can release too much water and become soggy.
What kind of cucumbers are best for this salad?
English cucumbers (also known as hothouse or seedless cucumbers) are ideal because they have thin skins and very few seeds, eliminating the need for peeling or deseeding. Regular slicing cucumbers can also be used, but you might want to peel them and scoop out any large seeds.
Can I use a different vinegar?
While apple cider vinegar provides a unique tang and slight sweetness, you can experiment with white wine vinegar or red wine vinegar for a different flavor profile. Balsamic vinegar would change the color and add a sweeter, more robust flavor, making it a different kind of salad.
