How to make Tomato Cucumber Onion Salad:
When our garden started overflowing with the cucumbers that Casey planted a couple of months ago, I knew that I better get to work and stir together this easy cucumber tomato salad. It's made with basic ingredients that I generally keep on hand at this time of year, so it was ready for the dinner table in just minutes (no grocery shopping necessary)!
Ingredients for Tomato Cucumber Onion Salad:
- Ripe tomatoes
- Red onion
- Fresh basil
- Olive oil
- Vinegar (I prefer apple cider vinegar or red wine vinegar)
- Salt and pepper
English Cucumber and Tomato Salad:
This Tomato Cucumber Onion Salad recipe works well with both regular cucumbers or English (seedless) cucumbers. I've shown regular cucumbers here, because that's what we have available in our garden right now. If using regular cucumbers with a thick, waxy skin, you'll want to peel the cucumbers before slicing. If you're using English cucumbers, you can skip the step of peeling the cucumbers because the skin is very thin.
Which Oil to use for a Healthy Cucumber Tomato Salad:
I recommend either red wine vinegar or apple cider vinegar for this recipe. You can also use balsamic vinegar, but the dark color of the balsamic will change the color of the vegetables.
Season with Fresh Herbs:
Basil is abundant at this time of year and is a natural companion for the juicy, ripe tomatoes. If you have other fresh herbs available, feel free to use them as well. Good options include thyme, rosemary, chives, parsley and oregano. They will all add to the Mediterranean taste of the salad.
Step 1: Place Vegetables and Herbs in a Bowl
Toss together tomatoes, cucumbers, onion and basil in a large bowl.
Step 2: Make the Dressing for Tomato Cucumber Salad
In a separate bowl or jar, whisk or shake together the olive oil and vinegar until combined. The simple dressing is as basic as it gets -- highlighting the natural flavors of the produce without overwhelming the dish.
Step 3: Dress Salad
Pour the vinaigrette over the vegetables and toss to coat. Season liberally with salt and pepper, to taste.
Step 4: Marinate
Allow the salad to sit and marinate for about 30 minutes, then stir and enjoy!

Tomato Cucumber Onion Salad Calories:
Each generous portion (⅙th of the dish) has about 194 calories, 18 grams of fat, 7 grams of carbs and 2 grams of protein. This is just an estimate, and will vary depending on how much dressing is actually consumed.
Preparation and Storage Tips:
- Make Ahead: This salad is best when it has a chance to marinate for at least 30 minutes or up to 1 hour. You can let it sit at room temperature while it marinates, or you can put it in the refrigerator if you prefer a cold salad.
- The flavors come together, the cucumbers marinate, and the onions pickle (giving them a more mild taste) while the salad rests. Don't skip that step!
- The salad will last in an airtight container in the fridge for up to 3 days, but it's best when enjoyed within about 24 hours. After a day or so, the vegetables get soft and the salad loses that satisfying crunch.
Cook's Tips and Recipe Variations - Greek Tomato Cucumber Onion Salad
- Tomato Cucumber Chickpea Salad: For more staying power, bulk up the salad with a can of drained, rinsed chickpeas. The extra protein and fiber can turn the dish into a satisfying vegetarian entrée.
- Cucumber Tomato Feta Salad: This Mediterranean-inspired dish is delicious with some crumbled feta cheese added to the mix.
- Cucumber Tomato Avocado Salad: Have a ripe avocado in the kitchen? Feel free to stir in 1 pitted, diced avocado. The fruit will add a nice, creamy texture and bright green color. If you're not serving the salad within 30 minutes, wait to add the avocado until the last minute. The avocado will turn brown if it sits out for too long.
- Cucumber Tomato Mozzarella Salad: Add diced fresh mozzarella or miniature mozzarella balls to the dish for a creamy addition.
- Tomato Cucumber Onion Salad with Italian Dressing: Instead of making your own vinaigrette with olive oil, vinegar, salt and pepper, you can substitute with about ½ cup of your favorite store-bought Italian dressing.
