Cucumber and Tomato Salad with Vinegar

By Jamie Cook — Home cook sharing tested recipes from a real kitchen.

Cucumber and Tomato Salad with Vinegar is the kind of recipe that makes you feel wildly accomplished for slicing vegetables and pouring dressing over them. It takes about 10 minutes, requires zero cooking, and delivers that crisp, tangy bite that makes a plate of grilled chicken suddenly look like you planned the whole dinner. Juicy tomatoes, crunchy cucumbers, thin red onion, fresh herbs, and a punchy vinegar dressing do all the heavy lifting. I like serving it slightly chilled, when the cucumbers stay snappy but the vinegar has had just enough time to mingle with the tomatoes. Basically, salad without the drama.

Why This Recipe is Awesome

Cucumber and Tomato Salad with Vinegar deserves a permanent spot in your summer rotation because it solves several problems at once: it uses basic produce, takes almost no time, and doesn’t require turning on the oven when your kitchen already feels like a sauna. The vinegar gives the vegetables enough personality to avoid tasting like “things I put in a bowl because I should eat vegetables.” Make it for dinner, cookout, lunch, or the random Tuesday when the fridge looks suspiciously empty.

Ingredients You’ll Need

• 2 medium English cucumbers — about 3 cups sliced; crisp cucumbers keep the salad from becoming floppy.
• 3 medium ripe tomatoes — about 3 cups chopped; choose tomatoes that smell like tomatoes, not disappointment.
• ½ small red onion — thinly sliced; enough bite without hijacking the entire bowl.
• 3 tablespoons red wine vinegar — the tangy backbone of the dressing.
• 2 tablespoons extra-virgin olive oil — rounds out the vinegar and helps carry the herbs.
• 1 teaspoon granulated sugar — a tiny amount balances the acidity without making the salad sweet.
• ¾ teaspoon kosher salt — seasons the vegetables and helps the flavors wake up.
• ¼ teaspoon freshly ground black pepper — because bland salad is nobody’s dream.
• 1 small garlic clove — finely minced; optional, but excellent if you like a savory punch.
• 2 tablespoons chopped fresh parsley — fresh and grassy, with zero complicated behavior.
• 1 tablespoon chopped fresh dill — optional, but especially good with cucumber.
• 1 tablespoon fresh lemon juice — optional; use it when you want extra brightness.

Step-by-Step Instructions

1. Slice the cucumbers and tomatoes into evenly sized pieces. Cut the cucumbers into thin rounds or half-moons about ⅛ to ¼ inch thick, then cut the tomatoes into bite-size wedges or chunks. Keep the pieces similar in size so every forkful gets a little cucumber and tomato instead of one lonely vegetable doing all the work.
2. Thinly slice the red onion. Cut the onion as thinly as you can manage, then separate the slices with your fingers. If your onion tastes particularly fierce, soak the slices in cold water for 5 minutes and drain them well before adding them to the bowl.
3. Make the vinegar dressing. Whisk together the red wine vinegar, olive oil, sugar, salt, black pepper, and minced garlic in a small bowl until the sugar and salt dissolve. The dressing should taste bright and tangy on its own, but not so sharp that it makes you squint.
4. Combine the vegetables and dressing. Add the cucumbers, tomatoes, red onion, parsley, and dill to a large bowl, then pour the dressing over everything. Toss gently with salad spoons so the tomatoes stay intact instead of turning into an accidental tomato sauce.
5. Let the Cucumber and Tomato Salad with Vinegar rest for 10 to 15 minutes. Leave the bowl at room temperature for about 10 minutes or refrigerate it briefly if you prefer a colder salad. The vegetables should look glossy and lightly coated, while the cucumbers should still have a noticeable crunch.
6. Taste and adjust the seasoning. Take a forkful and check the balance before serving. Add another pinch of salt if the vegetables taste flat, another splash of vinegar if you want more tang, or a teaspoon of olive oil if the acidity feels too aggressive.
7. Serve immediately or slightly chilled. Spoon the salad into a serving bowl and sprinkle a little extra dill or parsley over the top. I prefer serving it within a couple of hours because the cucumbers stay pleasantly crisp while the tomatoes release just enough juice to mingle with the dressing.

Common Mistakes to Avoid

• Using watery, underripe tomatoes — The salad cannot perform miracles. Pick ripe tomatoes with firm flesh and plenty of flavor.
• Drowning everything in vinegar — More acid does not automatically mean more flavor. Start with the measured amount and adjust after tasting.
• Cutting the onion too thickly — Huge onion chunks turn every bite into an onion audition. Slice them thin.
• Salting hours before serving — Salt pulls water from the vegetables, so your crisp salad can become a puddle with ambitions.
• Overmixing the tomatoes — Toss gently. You are making salad, not tomato confetti.

Alternatives & Substitutions

For a slightly different Cucumber and Tomato Salad with Vinegar, swap red wine vinegar for apple cider vinegar, white wine vinegar, or distilled white vinegar. Apple cider vinegar gives the dressing a softer, slightly fruity edge, while white vinegar produces a sharper, more traditional tang.

If you don’t have English cucumbers, use Persian cucumbers or regular garden cucumbers. Peel regular cucumbers if the skin feels tough, and scoop out some seeds if the center looks especially watery.

For a dairy-free salad, follow the recipe exactly as written; it already contains no dairy. For a vegan version, use maple syrup instead of honey if you decide to replace the sugar with a liquid sweetener.

Fresh dill and parsley work beautifully together, but you can use basil, cilantro, or a combination of whatever fresh herbs you have. Add crumbled feta for a salty Mediterranean-style variation, or toss in sliced Kalamata olives when you want something more substantial.

For extra crunch, add a little thinly sliced bell pepper. For heat, add a finely sliced jalapeño or a pinch of red pepper flakes. If you’re serving the salad beside grilled meat, a little extra black pepper and lemon juice make the vinegar dressing particularly lively.

If you want another easy vegetable side, try Greek cucumber salad or tomato onion salad.

Frequently Asked Questions

How long does cucumber and tomato salad with vinegar last in the refrigerator?

Cucumber and tomato salad with vinegar keeps well for about 1 to 2 days in an airtight container, although the vegetables become softer as they sit. For the best texture, serve it within several hours of dressing it.

Can I make cucumber and tomato salad with vinegar ahead of time?

Yes, but prepare the vegetables and dressing separately several hours ahead, then toss them together about 10 to 30 minutes before serving. This keeps the cucumbers and tomatoes noticeably crisper than dressing the entire salad the night before.

What vinegar is best for cucumber and tomato salad?

Red wine vinegar gives the salad a balanced, savory tang, but apple cider vinegar, white wine vinegar, or regular white vinegar also work. Choose red wine vinegar for a fuller flavor and white vinegar when you want a cleaner, sharper bite.

How do I keep cucumber and tomato salad from getting watery?

Use firm tomatoes, drain very watery cucumbers if necessary, and avoid salting the vegetables far in advance. Dressing the salad shortly before serving also limits the amount of liquid that collects at the bottom of the bowl.
