A simple tomato and cucumber salad is one of the easiest ways to put fresh produce on the table. With ripe tomatoes, crunchy cucumbers, a sharp homemade dressing, and a little time for the flavors to meet, you can make a refreshing side dish for almost any meal.
Ingredients for a Simple Tomato and Cucumber Salad
The recipe below makes approximately four side-dish servings. Use the freshest vegetables you can find, because the salad is mostly raw and every ingredient contributes directly to the final flavor.
| Ingredient | Amount | Preparation |
|---|---|---|
| Ripe tomatoes | 4 medium | Cut into bite-size pieces |
| Cucumber | 1 large or 2 small | Sliced or chopped |
| Red onion | 1/4 medium | Thinly sliced |
| Fresh parsley | 1/4 cup | Chopped |
| Olive oil | 3 tablespoons | For the dressing |
| Red wine vinegar | 1 1/2 tablespoons | For the dressing |
| Garlic | 1 small clove | Finely grated or minced |
| Salt | 1/2 teaspoon, plus more to taste | Divided as needed |
| Black pepper | 1/4 teaspoon | Freshly ground if possible |
You can also add 1 teaspoon of dried oregano, a squeeze of lemon juice, or a small amount of crumbled feta cheese. These additions are optional, but they work especially well if you want a more Mediterranean-style salad.
Choose tomatoes that are fragrant and firm enough to hold their shape. Roma, vine-ripened, cherry, grape, or garden tomatoes can all work. For cucumbers, English cucumbers have thin skins and fewer seeds, while standard cucumbers are perfectly suitable if they are crisp and fresh.
Prepare the Vegetables
-
Wash everything first. Rinse the tomatoes, cucumber, onion, parsley, and lemon if you are using one. Dry the vegetables with a clean towel or allow them to drain well. Excess water can dilute the dressing.
-
Cut the tomatoes. Remove the stem ends. Cut medium tomatoes into wedges or bite-size chunks. If the tomatoes are unusually watery, you can gently remove some of the seeds and pulp, but do not discard the flavorful flesh unnecessarily.
-
Cut the cucumber. Trim both ends, then slice the cucumber into half-moons about 1/4 inch thick. For larger cucumbers with tough skin or large seeds, peel them partially or completely and scrape out the seeds with a spoon. Small, thin-skinned cucumbers usually need no peeling.
-
Slice the onion. Cut the red onion as thinly as possible so its flavor does not overpower the salad. If you prefer a milder onion taste, place the slices in a bowl of cold water for 5 to 10 minutes, then drain and pat dry.
-
Chop the herbs. Remove any thick parsley stems and chop the leaves. If using fresh dill, mint, or basil, add a small amount alongside the parsley rather than replacing all of it at once. Strong herbs can change the character of the salad quickly.
Keep the pieces roughly similar in size. This makes each forkful easier to eat and helps the dressing coat the ingredients evenly.
Make the Dressing
Add the olive oil, red wine vinegar, garlic, half of the salt, black pepper, and optional oregano to a small jar or bowl. Whisk the mixture until it looks slightly blended, or close the jar tightly and shake it for about 10 seconds.
Taste a tiny amount with a clean spoon. The dressing should taste a little stronger than you want the finished salad to taste because the tomatoes and cucumbers will soften its intensity. If it seems too sharp, add another teaspoon of olive oil. If it tastes flat, add a small pinch of salt or a few drops of lemon juice.
You can adjust the dressing in several directions:
- Use lemon juice instead of some or all of the vinegar for a brighter flavor.
- Replace red wine vinegar with white wine vinegar, apple cider vinegar, or champagne vinegar.
- Add 1/2 teaspoon of honey or sugar if the tomatoes are not very sweet and the dressing tastes harsh.
- Add a pinch of chili flakes for gentle heat.
- Stir in a teaspoon of Dijon mustard to help the dressing emulsify and add savory depth.
- Use extra-virgin olive oil for a fuller flavor, or a mild olive oil for a more neutral result.
Avoid adding too much garlic at the start. Raw garlic becomes more noticeable as it sits, so it is easier to add another small amount later than to correct an overpowering dressing.
Assemble the Salad
Place the tomatoes, cucumber, onion, and parsley in a large bowl. Sprinkle with the remaining salt and toss gently. Let the vegetables stand for 5 minutes before adding the dressing. This short rest gives the salt time to draw out some flavor without making the vegetables noticeably soft.
Pour most of the dressing over the vegetables and fold everything together with a large spoon or salad servers. Use a gentle lifting motion instead of stirring aggressively, especially if the tomatoes are very ripe. Add the remaining dressing only if the salad appears dry.
Taste a piece of tomato and cucumber. Adjust the seasoning with more salt, pepper, vinegar, lemon juice, or olive oil as needed. If you are adding feta, olives, or another salty ingredient, season conservatively until those additions are mixed in.
For the best texture, serve the salad after about 10 to 15 minutes at room temperature. This gives the onion and dressing time to flavor the vegetables while keeping the cucumber crisp.
Variations to Try
This basic salad is easy to adapt to the meal you are serving.
Mediterranean tomato and cucumber salad
Add 1/2 cup of crumbled feta, a handful of pitted Kalamata olives, and 1 teaspoon of dried oregano. You can also include thin strips of green bell pepper. Reduce the added salt because feta and olives are already salty.
Creamy version
For a creamy salad, replace half of the olive oil with 3 tablespoons of plain Greek yogurt. Whisk the yogurt with lemon juice, a small grated garlic clove, pepper, and a pinch of salt. This dressing is thicker and should be added shortly before serving.
Herb-forward version
Use a mixture of parsley, dill, and mint. Start with about 2 tablespoons of each, then taste. Mint can become dominant, so add it gradually. This version pairs well with grilled chicken, fish, or roasted vegetables.
Avocado version
Add one diced avocado just before serving. Use lemon juice in the dressing and fold gently so the avocado does not become mashed. This variation is best eaten immediately because the avocado can darken and soften.
Spicy version
Add a thinly sliced jalapeño, a pinch of red pepper flakes, or a little hot paprika. Remove the jalapeño seeds if you want flavor with less heat.
More filling salad
Turn the side dish into a light lunch by adding chickpeas, white beans, cooked quinoa, hard-boiled eggs, or grilled chicken. Keep the dressing separate if you plan to prepare it ahead of time.
How to Prevent a Watery Salad
Tomatoes and cucumbers naturally release liquid, especially after salt is added. A little juice is desirable because it mixes with the dressing, but too much can make the salad bland and soggy.
Use these steps when excess liquid is a concern:
- Choose firm, ripe tomatoes rather than overripe tomatoes.
- Remove some tomato seeds and pulp if the variety is especially juicy.
- Salt the salad shortly before serving instead of hours in advance.
- Pat cucumbers dry after washing and cutting.
- For very watery cucumbers, sprinkle them lightly with salt and leave them in a colander for 10 to 15 minutes, then rinse briefly and dry thoroughly.
- Keep the dressing separate until you are ready to eat.
- Do not leave the finished salad in a warm place for an extended period.
If the salad has already become watery, drain off a little of the liquid, then refresh it with a small splash of vinegar, a drizzle of olive oil, and a pinch of seasoning. Do not add a large amount of dry seasoning at once, because it may make the outer vegetables taste too salty.
Common Problems and Easy Fixes
The salad tastes bland: Add salt first, then a little vinegar or lemon juice. Fresh salads often need more salt than expected because the vegetables contain a lot of water.
The dressing tastes too sour: Whisk in olive oil one teaspoon at a time. A small amount of honey or sugar can also round out sharp vinegar, but use it sparingly.
The onion is too strong: Remove the onion slices and soak them in cold water for several minutes. Drain and return them to the bowl. Next time, slice them more thinly or use shallot instead.
The tomatoes fall apart: The tomatoes were likely too soft or the salad was tossed too vigorously. Use a wide bowl and fold gently. Cherry tomatoes are often easier to handle than very ripe large tomatoes.
The cucumber tastes bitter: Bitterness can occur in some cucumbers, particularly near the ends. Trim both ends, taste a small slice, and discard the cucumber if the bitterness is pronounced throughout.
The salad tastes oily: Add vinegar or lemon juice a few drops at a time, then toss well. You can also add more tomato and cucumber if you have extra vegetables available.
The herbs turn dark: This usually happens when tender herbs are chopped far in advance or pressed under the dressing. Chop them shortly before serving and fold them in gently.
Make-Ahead and Storage Guidance
For the freshest result, prepare the components separately up to several hours ahead. Cut the vegetables, make the dressing, and store both covered in the refrigerator. Keep the herbs dry and add them when assembling the salad.
The finished salad is best served the same day. If necessary, refrigerate leftovers in a covered container and use them within 24 hours. The vegetables will soften and release more liquid, so the texture will not be identical to a freshly made salad.
Before serving refrigerated leftovers, let them sit at room temperature for 10 to 15 minutes. Drain excess liquid if necessary and taste again. Cold temperatures dull flavor, so a small pinch of salt or a few drops of vinegar may be needed.
Do not freeze this salad. Freezing damages the structure of raw tomatoes and cucumbers, leaving them watery and soft when thawed.
What to Serve with Tomato and Cucumber Salad
This salad is especially useful when a meal needs something crisp and acidic. Serve it alongside grilled chicken, burgers, kebabs, baked fish, omelets, roasted potatoes, rice dishes, or crusty bread.
For a simple lunch, spoon it over hummus with warm pita. Add chickpeas or feta for more protein and substance. It can also be served as part of a larger spread with olives, cheese, roasted vegetables, and grilled meats.
If serving outdoors or at a buffet, keep the bowl chilled and replenish it in smaller batches. Fresh tomatoes and cucumbers should not sit unrefrigerated for long periods, particularly in hot weather. Add creamy dressing only immediately before serving and return leftovers to the refrigerator promptly.
With properly prepared vegetables, a balanced dressing, and gentle mixing, this salad takes about 15 minutes to assemble and remains flexible enough for nearly any season or meal.
