🍅 Peak-Season Produce Shine
When tomatoes and cucumbers are at their best, you don’t need complicated dressings or heavy additions—the ingredients speak for themselves. One article emphasises:
“When so few ingredients are used, focus on quality, and the results will be stellar.”
This gives you both flavour and nutrition with minimal effort.
📋 Ingredients You’ll Need
Here’s a typical ingredient list inspired by classic versions. You can adjust quantities for servings or taste.
Vegetables:
- Cucumbers (2-3 medium or 1 large English cucumber) – peeled partially or fully depending on preference.
- Tomatoes (3-4 medium ripe tomatoes or a pint of cherry tomatoes) – ideally firm but ripe.
- Red onion (1 medium) – sliced thinly to distribute flavour.
Marinade / Dressing:
- Extra-virgin olive oil (3-4 tablespoons)
- Vinegar (white wine vinegar, red wine vinegar or sherry vinegar; ~2 tablespoons)
- Salt & pepper (to taste) – essential for seasoning.
- Optional: sugar (½-1 teaspoon), water (¼–½ cup) to balance acidity.
- Herbs (fresh parsley, basil or chopped dill; ~2 tablespoons) for freshness.

🔪 Step-by-Step Instructions
Follow these steps for a perfect marinated cucumber, onion & tomato salad.
Step 1 – Prepare the Produce
- Wash all vegetables thoroughly under cold water.
- Peel or partially peel the cucumber depending on skin thickness. Some prefer leaving the skin for colour and texture.
- Slice the cucumber into roughly ¼-inch pieces (or dice if preferred).
- Cut tomatoes into wedges or bite-sized chunks (cherry tomatoes can be halved).
- Slice the red onion thinly into half-moons, separating the layers lightly so the flavour infuses the marinade.
Step 2 – Make the Dressing / Marinade
- In a small bowl, whisk together olive oil, vinegar, salt, pepper, and optional sugar + water if you like a slightly sweeter/milder marinade.
- Add fresh chopped herbs (parsley, basil or dill) if using.
- Taste and adjust: if too tangy add a bit more oil or sugar; if too mild add more vinegar or herbs.
Step 3 – Combine & Marinate
- In a large bowl, combine the cucumber, tomato and onion pieces.
- Pour the marinade over the vegetables, toss thoroughly to coat everything evenly.
- Cover and chill in refrigerator for at least 30 minutes. Optimal marinating time is about 1 hour or more so flavours meld.
- Before serving, give a quick toss, taste and adjust seasoning (salt/pepper) if needed.

Step 4 – Serve & Enjoy
- Remove from fridge about 10 minutes before serving so it isn’t ice-cold.
- Serve in a large bowl or individual portions.
- Optional garnish: fresh herb sprigs, a drizzle of olive oil, or a sprinkle of feta cheese (if you like).
🍴 Tips for the Best Texture & Flavor
- Use firm, ripe vegetables: They hold up better in the marinade and retain crispness.
- Don’t skip chilling: Marinating allows the flavours to develop and the vegetables to slightly ‘soak up’ the dressing. One source explains how the veggies re-absorb their own juices plus marinade for fuller flavour.
- Cut vegetables evenly: Ensures consistent texture and flavour in each bite.
- Adjust marinade to your taste: Use more oil if you prefer mild tang, more vinegar for sharper flavour.
- Avoid soaking too long: While some prefer 12-24 hours, beyond that vegetables may soften too much and lose crunch.
- Keep it chilled until serving: Helps maintain crispness and freshness.
- Taste and season before serving: Flavours can mellow in the fridge—so a quick final tweak makes a big difference.
🌿 Variations & Customizations
Make the salad your own with these flavour-twist ideas:
🍋 Mediterranean Style
Add Kalamata olives, crumbled feta cheese, oregano, and lemon zest to the base for a Greek-inspired version.
🌶 Spicy Kick
Add finely chopped jalapeño or a sprinkle of red pepper flakes to the marinade for heat.
🥑 Rich-and-Creamy
Top with diced avocado and drizzle a bit of yogurt or tzatziki on the side for a creamy contrast.
🥜 Crunchy Nuts
Toss in toasted pine nuts or chopped walnuts at the last minute for crunch.
🌱 Fresh Herb Boost
Use a mix of mint, cilantro and basil instead of parsley to lighten the flavour profile.

Add chickpeas, grilled chicken slices, or cooked quinoa to make the salad substantial enough for a light meal.

🧊 Storage, Make-Ahead & Leftover Tips
- Prep ahead: Chop vegetables up to 12 hours ahead; store in separate containers to retain crispness.
- Assemble 30-60 minutes before serving for best texture.
- Storage: After marinating, the salad keeps in the fridge for up to 2-3 days in an airtight container. After that vegetables may soften.
- Leftovers: If the salad becomes too juicy or soft, drain some liquid, add fresh herbs and serve as a chilled salsa over grilled protein or boulgour.
- Travel friendly: Use a shallow sealed container and keep chilled until serving.
