Ingredients

For the Salad

• 2 medium cucumbers, washed and diced

• 3 medium ripe tomatoes, chopped

• 1 small red onion, thinly sliced

• 1 small green or red bell pepper, diced (optional)

• ¼ cup fresh parsley, finely chopped

• 2 tablespoons fresh mint, chopped (optional)

• ½ cup crumbled feta cheese (optional)

• ⅓ cup Kalamata olives, pitted and halved (optional)

For the Dressing

• 3 tablespoons extra-virgin olive oil

• 2 tablespoons fresh lemon juice

• 1 tablespoon red wine vinegar

• 1 small garlic clove, finely minced or grated

• ½ teaspoon dried oregano

• ¼ teaspoon freshly ground black pepper

• ¼ teaspoon salt, or to taste

• ½ teaspoon honey (optional)

Equipment Needed

• A large mixing bowl

• A small bowl or jar for the dressing

• A sharp knife

• A cutting board

• A spoon or salad tongs

• A vegetable peeler, if desired

Instructions

Step 1: Wash and Prepare the Vegetables

Begin by washing the cucumbers, tomatoes, bell pepper, parsley, and mint under cool running water. Pat the vegetables and herbs dry with a clean kitchen towel.

Clean, dry vegetables help keep the salad fresh and prevent unnecessary water from diluting the dressing.

Trim the ends of the cucumbers. You can leave the skin on for extra texture and color, especially if using thin-skinned cucumbers. If the skin is thick or bitter, peel some or all of it.

Cut the cucumbers into bite-sized pieces. Aim for similar sizes so each serving contains a balanced mixture of vegetables.

Step 2: Chop the Tomatoes

Cut the tomatoes into medium-sized wedges or bite-sized chunks. Choose ripe tomatoes that feel slightly soft but are not mushy.

Cherry tomatoes can also be used. Simply cut them in half or into quarters, depending on their size.

If your tomatoes are extremely watery, you may remove some of the seeds before chopping. This is optional, but it can help prevent excess liquid from collecting at the bottom of the bowl.

Transfer the chopped tomatoes to the mixing bowl.

Step 3: Slice the Red Onion

Peel the red onion and cut it into thin slices. Thin slices distribute the onion’s sharp flavor throughout the salad without making individual bites too intense.

If you prefer a milder onion flavor, place the slices in a bowl of cold water for five to ten minutes. Drain them thoroughly and pat dry before adding them to the salad.

Add the onion to the bowl with the cucumbers and tomatoes.

Step 4: Prepare the Fresh Herbs

Finely chop the parsley and mint, if using. Parsley provides a clean, slightly peppery flavor, while mint gives the salad a cool, refreshing finish.

If you do not have fresh mint, you can leave it out or substitute a small amount of fresh dill.

Add the herbs to the vegetables. Avoid chopping them too far in advance because freshly cut herbs generally retain their color and fragrance better when used soon after preparation.

Step 5: Make the Lemon-Olive Oil Dressing

In a small bowl, whisk together the extra-virgin olive oil, lemon juice, red wine vinegar, minced garlic, dried oregano, black pepper, salt, and optional honey.

Continue whisking until the ingredients are evenly combined.

Taste the dressing before adding it to the vegetables. If you prefer a sharper flavor, add a little more lemon juice or vinegar. If it tastes too acidic, add a small amount of olive oil. The optional honey can soften the acidity without making the dressing noticeably sweet.

Because tomatoes and cucumbers release moisture, the dressing should taste slightly bold before it is mixed with the salad.

Step 6: Combine the Salad

Pour the dressing over the cucumbers, tomatoes, and red onion.

Using salad tongs or two large spoons, toss gently until the vegetables are evenly coated. Avoid vigorous mixing because the tomatoes may break apart and release too much juice.

Add the chopped parsley and mint, then toss once more.

If using feta cheese or Kalamata olives, add them now. Fold them in gently to preserve the texture of the cheese and prevent the olives from crushing.

Step 7: Taste and Adjust

Taste a small portion of the salad and adjust the seasoning.

Add more black pepper for a stronger savory flavor, lemon juice for extra brightness, or a small pinch of salt if needed. Remember that feta and olives can already contribute considerable saltiness.

If the salad tastes too sharp, a small drizzle of olive oil can balance the acidity.

Step 8: Serve Fresh

Transfer the salad to a serving bowl. Garnish with a little additional parsley, a sprinkle of oregano, or a few thin onion slices.

For the freshest texture, serve immediately or within about 15–30 minutes of dressing. If you prefer a slightly more developed flavor, refrigerate it briefly before serving.

This salad tastes especially refreshing when served cool alongside grilled meats, fish, sandwiches, or other Mediterranean dishes.

Tips for the Best Cucumber, Tomato, and Red Onion Salad

Choose ripe, firm tomatoes. Tomatoes should be flavorful and juicy without being overly soft. A combination of different tomato varieties can make the salad more colorful.

Use crisp cucumbers. Fresh cucumbers provide the crunch that balances the juicy tomatoes. English cucumbers are a convenient option because they generally have thin skins and fewer prominent seeds.

Slice the onion thinly. Thin slices spread the flavor evenly and prevent the onion from overwhelming the other ingredients.

Dry the vegetables after washing. Excess water can dilute the dressing and make the salad less flavorful.

Dress just before serving. Cucumbers and tomatoes release liquid after they are salted and dressed. Adding the dressing shortly before eating helps maintain their texture.

Use fresh lemon juice. Freshly squeezed lemon gives the dressing a brighter flavor than bottled juice.

Do not oversalt. Feta, olives, and some vinegars can contribute saltiness. Taste the finished salad before adding extra salt.

Use quality olive oil. Extra-virgin olive oil adds a fruity, peppery richness that complements the fresh vegetables.

Delicious Recipe Variations

1. Greek Cucumber Tomato Salad

Add crumbled feta cheese, Kalamata olives, and a little extra oregano. This variation has a distinctly Greek-inspired flavor and pairs beautifully with grilled chicken or fish.

2. Cucumber Tomato Avocado Salad

Add one diced ripe avocado just before serving. Its creamy texture contrasts with the crisp cucumber and juicy tomatoes. Handle it gently to prevent the avocado from becoming mashed.

3. Chickpea Cucumber Tomato Salad

Mix in one cup of drained and rinsed chickpeas. They provide additional protein and fiber, making the salad more substantial as a light lunch.

4. Spicy Cucumber Tomato Salad

Add a finely chopped jalapeño or a pinch of red pepper flakes to the dressing. The heat provides an interesting contrast to the refreshing vegetables.

5. Cucumber Tomato Corn Salad

Add ½–1 cup of cooked and cooled sweet corn. The corn introduces a pleasant sweetness and a little extra texture.

6. Creamy Cucumber Tomato Salad

Replace part of the olive oil dressing with a few tablespoons of plain Greek yogurt. Add lemon juice, black pepper, and chopped dill for a creamy variation. Keep it refrigerated until serving.

7. Cucumber Tomato Feta Herb Salad

Increase the amount of parsley and add fresh dill or mint. Crumbled feta contributes a salty, tangy flavor that makes this version especially satisfying.

8. Mediterranean White Bean Salad

Add drained cannellini beans or butter beans. Combine with the lemon dressing and parsley for a more filling plant-based dish.

What to Serve with This Salad

Cucumber, Tomato, and Red Onion Salad is a versatile side dish that complements many meals.

• Grilled chicken: Lemon-herb chicken pairs beautifully with the fresh vegetables and tangy dressing.

• Baked white fish: Cod, haddock, or another mild fish works well with the salad’s bright lemon flavor.

• Grilled shrimp: The crisp vegetables provide a refreshing contrast to savory seafood.

• Beef or chicken kebabs: Serve the salad alongside kebabs, rice, and warm flatbread.

• Falafel and hummus: The salad adds freshness to a vegetarian Mediterranean meal.

• Roasted potatoes: The acidic dressing balances the richness of crispy or roasted potatoes.

• Pita sandwiches: Add the salad to a pita with grilled chicken, chickpeas, or falafel.

• Rice bowls: Serve it beside rice, grilled vegetables, and your favorite protein.

It is also an excellent addition to summer barbecues, outdoor lunches, family buffets, and casual dinner parties.

Serving and Presentation Ideas

For an attractive presentation, arrange the cucumber pieces and tomato wedges in a wide shallow bowl rather than crushing everything together. Scatter the red onion slices and fresh herbs over the top.

Finish with a light drizzle of olive oil and a few turns of freshly ground black pepper. If using feta, add it at the very end so its white color stands out against the red tomatoes and green cucumbers.

For individual servings, divide the salad into small bowls just before the meal. This is especially convenient for family dinners and gatherings.

If preparing a larger batch, keep the dressing separate until serving time. This helps the vegetables retain their crispness for longer.

Storage Instructions

This salad is best enjoyed freshly prepared because cucumbers and tomatoes release liquid as they sit.

If you have leftovers, transfer them to an airtight container and refrigerate promptly. For the best quality, consume the dressed salad within about 1–2 days. It may remain safe for longer under proper refrigeration, but its texture and appearance can deteriorate.

Keep the salad refrigerated at 40°F (4°C) or below. Do not leave it at room temperature for more than two hours, or more than one hour when the temperature is above 90°F (32°C).

If preparing ahead, chop the vegetables and refrigerate them separately from the dressing. Combine everything shortly before serving.

Freezing is not recommended because cucumbers and tomatoes become soft and watery after thawing.
