What you’ll need

English cucumbers typically have fewer seeds and less water than slicing cucumbers. If you’re using a slicing cucumber, be sure to scoop out the seeds with a spoon and blot away as much moisture as possible with a paper towel so the dressing sticks.

Cherry tomatoes are my go-to for salads. They are perfectly bite-sized, firm, and juicy. Grape, plum, and San Marzano tomatoes are also delicious. To finish it off, mix in fresh parsley and red onion (or for a more mild onion flavor, you can use thinly sliced shallot) to the salad.

For the vinaigrette dressing, you’ll need:

Extra virgin olive oil
Red wine vinegar
Garlic cloves
Dried oregano
Dijon mustard
Kosher salt
Freshly ground black pepper

Note: You can also swap in Italian dressing if you’ve got some on hand.

How to make a cucumber and tomato salad

First, halve the cucumber lengthwise and scoop the seeds out with a spoon. Slice each half into ¼ inch thick half-moons. Chop the tomatoes in half, thinly slice the red onion, chop the parsley, and mince or grate the garlic cloves.

In a small bowl, whisk together the olive oil, vinegar, garlic, oregano, mustard, salt, and pepper.

Add the cucumber, tomatoes, red onion, and parsley to a large bowl and pour the dressing over the top. Give everything a quick toss and then set the salad aside to allow the flavors to mingle. Serve with dinner and enjoy!

Make ahead and storing

This summer salad will taste its best if it’s assembled at least 30 minutes ahead of serving. This gives the dressing time to “marinate” the veggies but isn’t long enough to make them soggy. If you’d like to save more time, chop the veggies and mix the dressing a day in advance, store them in the fridge, and then toss them all together 30 minutes before serving.

Keep any leftover salad in an airtight container in the fridge for 3 to 4 days. Just keep in mind that the veggies will soften as they sit in the dressing, possibly making the leftovers soggy.

Variations:

This simple cucumber tomato salad recipe leaves plenty of room to toss in additional ingredients and switch up the flavors:

Cheese: This cool and crisp salad tastes excellent with creamy cubed feta or mozzarella balls tossed in before serving.
Herbs: Feel free to swap the fresh parsley for dill, basil, or a little bit of each.
Greens: Add spinach, arugula, or romaine lettuce to give the salad a little more substance.
Spice: Want to give your salad a little heat? Add ½ to 1 teaspoon of red pepper flakes to the vinaigrette.
Dressing: Use the red wine vinaigrette recipe as a guide and experiment with other flavors you like. Try using white wine vinegar instead of red and add in freshly chopped herbs or lemon juice/zest. Or, try swapping in this homemade Italian dressing. The options are endless!
