Essential Ingredients for a Tomato Cucumber and Onion Salad

This classic and refreshing side dish comes together with just a handful of simple, fresh ingredients.

  • Tomatoes: 1 pint of cherry or grape tomatoes, halved
  • Cucumbers: 2 medium cucumbers, sliced or chopped
  • Onion: 1 medium red onion, thinly sliced
  • For the Simple Vinaigrette:
    • ¼ cup of red wine vinegar
    • 2 tablespoons of olive oil
    • 1 teaspoon of granulated sugar
    • ½ teaspoon of dried oregano
    • Salt and freshly ground black pepper to taste

Ingredients Notes

A little more detail on our key ingredients will ensure your salad is a spectacular success.

  • The Tomatoes: For the best, sweetest flavor, it is highly recommended to use ripe, in-season cherry or grape tomatoes. Their small size means they have a great skin-to-flesh ratio and hold their shape beautifully in the salad. If you have access to large, beautiful heirloom tomatoes, they would also be a fantastic choice.
  • The Cucumbers: You can use any type of cucumber you like for this recipe. A classic garden cucumber, an English cucumber, or the smaller Persian cucumbers will all be delicious. The most important thing is that they are fresh and crisp.
  • The Red Onion: A red onion is the perfect choice for this salad as it provides a beautiful pop of purple color and a slightly milder, sweeter flavor than a yellow onion. Slicing it as thinly as you possibly can will ensure that its flavor is present but not overpowering.
  • The Vinaigrette: Our simple vinaigrette is all about balance. The red wine vinegar provides a bright, tangy base, while the small amount of sugar perfectly balances the acidity. A good quality olive oil adds a touch of fruity richness to the final dish.

How to Prevent It From Becoming Watery

Let’s walk through the incredibly simple steps to create this perfect, refreshing side salad.

  • Step 1: The Secret to a Non-Watery Salad. First, place your halved cherry tomatoes and your chopped cucumbers in a colander set over a large bowl. Sprinkle them generously with about a half teaspoon of salt and toss to combine. Let the vegetables sit in the colander for about 20 to 30 minutes to allow the salt to draw out their excess water.
  • Step 2: Create the Vinaigrette. While the vegetables are resting, you can prepare your simple dressing. In a small bowl or a jar with a lid, combine the red wine vinegar, the olive oil, the granulated sugar, the dried oregano, and a pinch of black pepper. Whisk or shake the dressing together until it is well combined.
  • Step 3: Combine the Salad. After 30 minutes, discard the water that has collected in the bottom of the bowl. Gently pat the salted tomatoes and cucumbers dry with a paper towel. Place the drained vegetables in a large serving bowl with the thinly sliced red onion.
  • Step 4: Dress and Serve. Pour the prepared vinaigrette all over the vegetables in the bowl. Toss everything together gently until the vegetables are evenly coated in the dressing.
  • Step 5: Chill and Enjoy. You can serve the salad immediately, or for the best flavor, you can let it marinate in the refrigerator for about 15-30 minutes before serving.

Storage Options

This classic cucumber and tomato salad is at its absolute best when it is enjoyed on the day it is made, while the vegetables are at their crispiest. If you do have any leftovers, you can store them in an airtight container in the refrigerator for up to 2 days. The vegetables will soften slightly as they continue to marinate, but they will still be delicious.

Variations and Substitutions

This incredibly simple recipe is a perfect blank canvas for your own creative additions. You can easily add other fresh, crunchy vegetables to the salad, such as some chopped bell peppers or celery. For a different flavor profile, feel free to add other fresh herbs, like some chopped parsley, dill, or basil. For a creamy version, you could add some crumbled feta cheese to the salad right before serving.

Practical & Valuable Tips

For the absolute best flavor, use the freshest, ripest, and most in-season vegetables you can possibly find. The most important tip for this recipe is to not skip the initial step of salting and draining your tomatoes and cucumbers; this is the non-negotiable secret to a crisp, flavour-packed salad that is never watery. Finally, for the crispiest result, it is a great idea to dress the salad right before you plan to serve it.

Frequently Asked Questions

  1. Do I have to peel my cucumbers for this recipe? This is a matter of personal preference. If you are using a thin-skinned variety like an English or a Persian cucumber, there is no need to peel them. If you are using a standard garden cucumber with a thicker, waxier skin, peeling it is often a good idea for the best texture.
  2. Can I use a different kind of vinegar? Yes, you can. While red wine vinegar provides a classic, robust flavor, this salad would also be fantastic with a slightly sweeter apple cider vinegar, a standard white vinegar, or even a white balsamic vinegar.
  3. How long does this salad last in the refrigerator? Because of our special salting trick, this salad holds up much better than most. It will stay fresh and delicious in an airtight container in the refrigerator for up to 2 days, though it will be at its absolute crispiest on the first day.
  4. Can I make this salad ahead of time for a party? Yes, this is a great make-ahead side dish. You can chop all of your vegetables and prepare your vinaigrette ahead of time and store them in separate containers in the refrigerator. When you are ready to serve, you can simply toss everything together.
  5. What are the best meals to serve with this cucumber and tomato salad? This refreshing salad is the perfect accompaniment to a huge variety of summer meals. It is fantastic with classic barbecue dishes like grilled chicken or burgers. It is also a wonderful and classic side dish for a simple potluck, a summer picnic, or alongside some grilled fish.
