This is a chopped salad of heirloom tomatoes, black olives, cucumber, and red onion dressed with olive oil and red wine vinegar — ready in 20 minutes with no cooking required. It holds up well on a table for an hour, which makes it genuinely useful when you’re feeding a group and need one less thing to fuss over at the last minute.
The technique that matters
Two things make a real difference here. First, soaking the sliced red onion in cold water for 10 minutes before adding it to the bowl. Raw onion can bulldoze everything else in a salad like this — the soak pulls out the harsh compounds and leaves you with a milder, slightly crisp bite that doesn’t compete with the tomatoes. Drain it well and pat it dry so you’re not watering down the dressing. Second, let the dressed salad sit at room temperature for 10 to 15 minutes before serving. The tomatoes release a little juice, the vinegar softens slightly, and everything tastes more cohesive. If you’re doubling or tripling the recipe for guests, you can do all the chopping ahead and keep the components separate, then toss with dressing about 20 minutes before you’re ready to eat — skip the garnish of extra parsley on top, not worth the extra dish.
If something goes sideways
- The salad is swimming in liquid: Tomatoes keep releasing juice after they’re dressed, especially if they sit too long. If you’re making a large batch ahead, salt the chopped tomatoes separately in a colander for 15 minutes and let them drain before combining — this removes excess moisture upfront.
- The dressing tastes flat: Olive oil and red wine vinegar need salt to come alive. Taste the dressing before you pour it, not after. A pinch more sea salt usually fixes it immediately.
- The olives are too salty: Brined olives vary a lot by brand. If yours taste very salty straight from the jar, a quick rinse and a 5-minute soak in plain cold water will dial it back without stripping all the flavor.
- The cucumber goes soft: English cucumber holds its texture better than regular cucumber, but if yours sat in the dressing for more than 30 minutes it will start to soften. For a crowd, add the cucumber to the bowl last, right before serving.
- Scaling up and the dressing isn’t coating evenly: When you double or triple the recipe, whisk the dressing in a jar with a lid and shake it hard just before pouring — it emulsifies better at volume than whisking in a small bowl.
Storage and reheating
Store leftovers in an airtight container in the fridge for up to 2 days. The tomatoes will continue to soften and release liquid, so the texture on day two is noticeably more relaxed — still good, just less crisp. Give it a quick drain and a small drizzle of fresh olive oil before serving again to bring it back. Do not freeze this salad; the tomatoes and cucumber turn mushy and there’s no recovering them. There’s no reheating step — serve it cold or at room temperature straight from the fridge.
Croatian Black Olive and Tomato Salad
Equipment
- Cutting board
- Chef's Knife
- Large mixing bowl
- Small whisk or fork for dressing
- Salad tongs or serving spoon
Ingredients
For the Salad Base:
- 4 cups ripe heirloom tomatoes chopped into bite-size chunks
- 1 cup pitted black olives preferably Croatian or Kalamata, halved
- 1 medium red onion thinly sliced
- 1 cup English cucumber sliced into thin half moons
- ⅓ cup fresh parsley chopped finely
For the Dressing:
- ¼ cup extra virgin olive oil Croatian or high-quality Mediterranean variety
- 2 tablespoons red wine vinegar can substitute with sherry or white wine vinegar in a pinch
- 1 teaspoon sea salt or to taste
- ½ teaspoon cracked black pepper freshly ground for best flavor
Instructions
- Begin by preparing your vegetables. Dice the heirloom tomatoes into bite-sized chunks. Aim for uniform sizes to ensure even coating with the dressing and consistent mouthfeel.
- Halve the black olives. If using brined olives, rinse gently and dry with paper towels to avoid overpowering saltiness.
- Thinly slice the red onion into half-moons, then soak in cold water for 10 minutes to mellow its sharpness. Drain well before adding to the salad.
- Slice the English cucumber thinly into half-moons. Leave the skin on if tender, as it adds a pleasant crunch and color.
- In a large mixing bowl, combine the tomatoes, olives, cucumbers, onions, and chopped parsley.
- In a small bowl, whisk together the olive oil, red wine vinegar, sea salt, and cracked black pepper until emulsified. The dressing should appear slightly cloudy and viscous.
- Pour the dressing over the salad ingredients and gently toss to coat evenly. Let the salad rest for 10–15 minutes at room temperature for flavors to meld beautifully.
Notes
- For an added twist, sprinkle crumbled feta or grated Paški sir (Croatian sheep’s milk cheese) right before serving.
- Want to add more body? Mix in cooked farro or toasted rustic bread cubes to turn it into a Panzanella-style meal.
- This salad holds up well if prepped an hour in advance — just add the dressing just before serving.
- If you want to enhance the sweetness of the tomatoes, season them separately with a pinch of salt and let them sit for 5 minutes to draw out their juices.

Common questions
Can I use regular black olives from a can instead of Kalamata or Croatian olives?
You can, but the flavor will be noticeably milder and less complex. Canned California-style black olives are very mild and slightly rubbery — Kalamata olives are worth the small price difference here because their brininess is a main flavor in the salad, not just a supporting ingredient.
Can I make this salad several hours ahead for a party?
Yes, with one adjustment: keep the dressing separate until about 20 minutes before serving. You can chop and combine all the vegetables in the bowl, cover, and refrigerate for up to 4 hours — just add the cucumber and dressing close to serving time so nothing goes soggy.
What can I add to make this more substantial as a main?
Crumbled feta or chunks of good canned tuna work well and require no extra prep. Either one adds enough protein to turn this into a light lunch on its own, and both pair naturally with the olive oil and vinegar dressing already in the bowl.
