If there’s one recipe that defines our summers in the kitchen, it’s this cucumber tomato salad. From June through September, we’re making some version of it almost every single week and honestly, we never get tired of it. It’s that rare dish that’s so simple to pull together that it barely feels like cooking, but also fresh and flavorful enough that it earns a spot at the table every single time. Just 15 minutes, a handful of affordable ingredients, and dinner suddenly feels complete.

What keeps us coming back to it week after week is how easy it is to make it feel new. Sometimes we’ll fold in avocado or crumbled feta, swap the cilantro for fresh basil, or add a little jalapeño when we want some heat. The base recipe is so versatile that it naturally invites those little tweaks, which means it never feels repetitive. Whether we’re keeping it classic or riffing on it depending on what’s in the fridge, this is the side dish reach for all summer long without a second thought.

Why we love this cucumber tomato salad

• Ready in 15 minutes — This salad comes together super fast. A little chopping, a quick toss, and 10 minutes in the fridge is all it takes before it’s on the table.
• Budget-friendly — Every ingredient is affordable and easy to find at any grocery store, making this one of the most cost-effective side dishes you can put together all summer long.
• No cooking required — There’s zero heat involved, which makes this a dream on hot days when you want a fresh, satisfying dish without turning on the stove or oven.
• Incredibly versatile — This salad goes with almost everything: grilled meats, fish, sandwiches, wraps, rice dishes, and more. It’s the kind of side dish that fits into any meal.
• Light and refreshing — With crisp cucumbers, juicy tomatoes, and a bright lemony dressing, this salad feels clean and satisfying without being heavy or overly filling.

Ingredients needed

• Tomatoes: We use whatever ripe tomatoes we have on hand. Roma, cherry, or vine tomatoes all work beautifully here.
• Cucumber: We love using English cucumbers because they’re less seedy and have a thin skin, but any cucumber works. They add that cool, satisfying crunch that makes this salad so refreshing, especially straight out of the fridge on a hot summer day.
• Red onion: We chop it nice and fine so you get a little bit of that subtle sharp bite in every forkful without it overpowering the other flavors.
• Fresh lemon juice: This is the secret to keeping this salad bright and vibrant. Tossing the veggies with lemon juice first draws out the excess moisture from the tomatoes and cucumber while also seasoning everything from the inside out.
• Salt & pepper: We season the veggies right along with the lemon juice so the salt can do its job of pulling out moisture early. Don’t be shy here; proper seasoning at this stage is what makes the whole salad taste alive.
• Extra-virgin olive oil: We stir in the olive oil right before serving so it coats everything in a light, silky finish without making the salad greasy. A little goes a long way, and it ties all the flavors together beautifully.
• Fresh cilantro: Cilantro goes right in with the other veggies before the salad chills, so it has time to meld with the lemon juice and seasoning. It gives everything an herby, slightly citrusy lift that makes it taste bright and summery.

How to make cucumber tomato salad

1. Chop the veggies

Chop the tomatoes and cucumbers into bite-sized pieces and finely chop the red onion and cilantro. Add everything to a large mixing bowl and toss with lemon juice, salt, and pepper.

2. Chill for 10 minutes

Cover the bowl and place it in the refrigerator for 10 minutes. This resting time is important, as it lets excess moisture release from the veggies so your salad stays crisp and flavorful, not soggy and watery.

3. Drain the excess

After 10 minutes, remove the bowl from the fridge and transfer it to a serving bowl. Make sure to drain out any excess liquid that has accumulated at the bottom.

4. Add olive oil, taste, and serve!

Drizzle the olive oil over the salad and toss gently to combine. Give the salad a final taste and adjust salt, pepper, or lemon juice as needed. Serve immediately or refrigerate until ready to serve. That’s it!

What to serve with cucumber tomato salad

• Grilled chicken or steak: The bright, acidic flavors cut through rich grilled meats perfectly.
• Rice dishes: Serve with some rice pilaf, herbed rice, or even plain white rice for a complete, balanced plate.
• Pita bread and hummus: Scoop it up with warm pita for a simple, satisfying Mediterranean-style spread. You can also pile it inside a wrap for added freshness and crunch.
• Burgers and sandwiches: Skip the heavy sides and serve this as a light, refreshing counterpart.
• Grilled corn on the cob: A classic summer pairing that needs no explanation.

Cucumber tomato salad variations

One of the best things about this salad is how easy it is to make it your own. Here are some delicious ways we like to switch it up:

• Swap the herbs. Fresh parsley or basil are both wonderful substitutes and still give the salad its delicious flavor profile.
• Add avocado. Dice up a ripe avocado and fold it in just before serving for a creamy, buttery element that makes this feel a little more substantial. It pairs especially well with the lemon.
• Make it Greek style. Add crumbled feta cheese, a handful of Kalamata olives, and swap the lemon juice for red wine vinegar for a Greek-inspired twist that’s just as easy and just as fresh.
• Toss in chickpeas. Stir in a drained and rinsed can of chickpeas to add protein and turn this side dish into a light, filling lunch on its own.
• Spice it up. Add a finely minced jalapeño or a pinch of red pepper flakes for a little heat that plays really well against the cool cucumber and juicy tomatoes.

Cucumber tomato salad storage tips

To make ahead

Prep the veggies and toss with lemon juice, salt, and pepper, then refrigerate. Add the olive oil and cilantro right before serving for the freshest result.

To store

• Store in an airtight container in the refrigerator for up to 2 days.
• Do not freeze, as the cucumbers and tomatoes will lose their texture completely once thawed.
