How to Make Cucumber, Onion, and Tomato Salad Recipe
Step 1: Prepare the Vegetables
Start by washing your cucumbers and tomatoes thoroughly. Thinly slice the cucumbers so they have a delicate crunch and slice the tomatoes into wedges or thick slices to keep them juicy and substantial. Then, thinly slice the red onion to introduce that perfect zesty layer that complements the cool cucumbers and ripe tomatoes beautifully. Combining these fresh ingredients in a large bowl sets the foundation for your salad.
Step 2: Make the Marinade
In a small bowl, whisk together the vinegar, olive oil, sugar if you’re using it, salt, black pepper, and oregano. This marinade is the heart of the dish — it’s where tanginess, aroma, and a touch of sweetness come together to elevate each bite of vegetable. Tasting as you go will help you find the perfect balance for your palate, whether you prefer it zestier or with a milder tang.
Step 3: Toss the Salad
Pour your freshly made marinade over the bowl of cucumbers, tomatoes, and onions. Toss everything together gently but thoroughly to ensure each crunchy cucumber slice and sweet tomato wedge is evenly coated with that flavorful dressing. This is where the magic of the Cucumber, Onion, and Tomato Salad Recipe really starts to take shape.
Step 4: Marinate
Cover your bowl tightly and refrigerate for at least one hour. This step allows the vegetables to soak up all those gorgeous flavors, softening the onions slightly and letting the vinegar and herbs mingle beautifully. If time allows, letting it marinate overnight will make the flavors even more intense and harmonious. Patience here truly rewards you with a salad that sings on your taste buds.
Step 5: Garnish and Serve
When you’re ready to serve, give the salad another light toss to redistribute any settled dressing. Sprinkle the chopped fresh parsley over the top for an added pop of color and fresh herbal brightness that complements the oregano in the dressing. Now, your salad is ready to impress!

Garnishes
Adding extra fresh parsley or even a sprinkle of crumbled feta cheese can bring new layers of flavor and texture to your salad. A few olives or a drizzle of balsamic glaze make excellent garnishes, turning this humble salad into an elegant dish suitable for any occasion.
Side Dishes
This salad pairs wonderfully with grilled meats like chicken or lamb, seafood, or even alongside a hearty pasta dish. Its refreshing crunch and tang provide a perfect contrast to richer mains, making every bite balanced and satisfying.
Creative Ways to Present
For a fun twist, try serving the salad in hollowed-out tomatoes or cucumber boats. Layering the salad on a platter with fresh herbs and lemon wedges makes for a stunning centerpiece that invites everyone to dig in. This salad is as visually appealing as it is delicious.
Make Ahead and Storage
Storing Leftovers
You can keep any leftover salad in an airtight container in the refrigerator for up to two days. Keep in mind, the longer it sits, the more the vegetables will soften and the flavors intensify, so it’s best enjoyed fresh but still tastes great if refrigerated overnight.
Freezing
This salad is not ideal for freezing because cucumbers and tomatoes have high water content and will become mushy upon thawing. It’s best to prepare this salad fresh or soon before serving to maintain its delightful texture.
Reheating
Since this is a cold salad, reheating is not recommended. Instead, give leftovers a quick stir and bring them back to room temperature if desired, or enjoy straight from the fridge for a refreshing experience.
FAQs
Can I use other types of onions for this salad?
Absolutely! While red onions add a nice color and mild sweetness, you can substitute with white or sweet onions if you prefer a different flavor profile. Just slice them thinly to keep the texture right.
Is it necessary to let the salad marinate?
Marinating helps the flavors meld and softens the onions, making the salad more flavorful and enjoyable. While you can eat it immediately, allowing it to chill for at least an hour makes a noticeable difference.
Can I add other vegetables to this salad?
Definitely! Bell peppers, radishes, or even avocado can complement the existing flavors. Just remember to keep the vegetables fresh and slice them similarly to maintain a balanced texture.
What is the best vinegar to use?
White vinegar or apple cider vinegar works beautifully here due to their clean, bright acidity. You can also experiment with red wine vinegar for a slightly different tang, but avoid stronger, harsher vinegars that may overpower the salad.
Is this salad suitable for meal prep?
Yes! It’s a great option for a make-ahead dish as the flavors develop wonderfully over time. Just keep it refrigerated and enjoy within a day or two for optimal freshness.
