Ingredients
To prepare a bowl of fresh and zesty marinated cucumber, onion, and tomato salad, gather the following ingredients:
- 2 large cucumbers
- 1 red onion
- 3 ripe tomatoes
- ¼ cup white vinegar
- 2 tablespoons olive oil
- 1 tablespoon sugar
- 1 teaspoon salt
- ½ teaspoon black pepper
These basic components create the perfect balance of acidity, sweetness, and savoriness. Use fresh, high-quality vegetables for the best flavor.
Preparation Steps
Slice the Cucumbers
Start by washing and peeling the cucumbers. You can leave the skin on for added texture and color if you prefer. Slice them into thin rounds and place them in a large mixing bowl.
Slice the Onion
Peel the red onion and slice it into thin rings or half-moons, depending on your preference. Thinner slices allow the onion to marinate more effectively and blend into the dish without overpowering it.
Cut the Tomatoes
Wash the tomatoes thoroughly. Cut them into wedges or bite-sized chunks and add them to the mixing bowl with the cucumber and onion.
Make the Dressing
In a small bowl or measuring cup, whisk together the white vinegar, olive oil, sugar, salt, and black pepper until the mixture is well combined and slightly emulsified.
Combine and Marinate
Pour the dressing over the vegetables in the mixing bowl. Gently toss everything together, ensuring that the dressing coats all the slices evenly. Use a large spoon or your hands to mix without bruising the tomatoes.
Chill Before Serving
Cover the bowl with plastic wrap or a lid and refrigerate the salad for at least 1 hour. This marination process allows the flavors to meld and intensify. For best results, let it sit for 2–4 hours.

Serving Suggestions
This marinated salad is a fantastic match for:
- Grilled meats: Pair it with grilled chicken, pork chops, or burgers.
- Picnic spreads: Add it to a table alongside pasta salads, deviled eggs, or potato salad.
- Mediterranean feasts: Serve with hummus, pita, and olives.
- Simple dinners: Use it as a fresh side for roasted fish or baked tofu.
Serve chilled for the most refreshing experience, and give it a final toss before plating to redistribute the marinade.
Storage and Leftovers
This salad keeps well in the fridge for up to 2 days, though it’s best enjoyed within 24 hours for optimal crunch and flavor.
- Storage: Keep it in an airtight container.
- Revive leftovers: Add a splash of fresh vinegar or oil before serving.
- Avoid freezing: This salad is best fresh; freezing will ruin the texture of the vegetables.
Tips for the Best Marinated Salad
- Use firm, fresh vegetables: Ripe but sturdy tomatoes and firm cucumbers hold up best during marination.
- Slice evenly: Uniform cuts allow the marinade to penetrate evenly and create a balanced texture.
- Let it rest: Allowing time for marination is essential. The longer it sits (within reason), the more flavorful it becomes.
- Balance the flavors: Taste the dressing before pouring—adjust vinegar, sugar, or salt as needed.
- Marinate onions separately: If you prefer a mellow onion flavor, soak the onion slices in the dressing for 15 minutes before adding the other vegetables.
FAQs
Can I make this salad ahead of time?
Yes, and it’s actually better when made in advance. Prepare it 1–4 hours before serving to allow the flavors to meld. Just give it a quick stir before serving.
How long will this salad last in the fridge?
It’s best within 1–2 days. Beyond that, the cucumbers and tomatoes may become overly soft.
Can I use cherry or grape tomatoes?
Absolutely! Just slice them in halves or quarters. They’re especially good if you want to avoid too much tomato juice watering down the salad.
Do I have to peel the cucumbers?
Peeling is optional. If using thin-skinned cucumbers like English or Persian, you can leave the skin on for extra texture and color.
Can I use other onions besides red onions?
Yes. Sweet onions or shallots work well too. Red onions offer a sharp, slightly sweet bite and vibrant color, making them a favorite for this dish.
Can I make it without oil?
You can, though oil helps smooth out the vinegar’s sharpness. For an oil-free version, reduce the vinegar slightly or add a splash of water to mellow the flavor.
