Cucumber Tomato Salad

This Cucumber Tomato Salad recipe is a classic Summer side dish that’s filled with sliced cucumbers, juicy tomatoes and thinly sliced onions, then tossed in a light and refreshing vinaigrette dressing. 

Serve this delicious cucumber tomato onion salad with any grilled meats, baked salmon, chicken kabobs or even my favorite pork tenderloin.

How To Make Cucumber Tomato Salad

There really is no wrong time to make this bright and flavorful salad, but when the cucumbers and tomatoes are in peak season (Summer time), that’s when this lovely side dish recipe shines.

  • Combine the cucumbers, tomatoes, onions and herbs in a large bowl.
  • Place the dressing ingredients (see below) in a small mason jar and shake.

What Kind of Cucumbers To Use?

I’m using the long English cucumbers in this recipe because the peels are nice and thin and the seeds are also really small and easy to eat.

If you don’t have English cucumbers, you can easily use regular cucumbers that are peeled.

If the seeds are too coarse, feel free to scoop them out before chopping and adding to the salad.

Dressing for Cucumber Salad

Not much is needed here, as we’re really wanting to let the fresh flavors of the cucumbers, tomatoes and onions shine. I’m using equal parts oil and  vinegar because I simply adore how the vinegar really boosts the flavors.

  • 2 tbsp extra virgin olive oil
  • 2 tbsp red wine vinegar
  • 1 tsp minced garlic
  • 1/2 tsp salt
  • 1/4 tsp black pepper

PRO TIP: You can also use a white wine vinegar or apple cider vinegar in place of the red wine vinegar. It’ll change the flavor slightly, but should still be amazing!

Tips and Variations:

  • Swap out the white onion with a purple onion for a more mild flavor.
  • You can use fresh or dried herbs. If using dried, use half the amount called for the in the recipe.
  • I’m using grape tomatoes, but you can also use regular plump tomatoes that are chopped.
  • Keep the salad covered and stored in the fridge until ready to serve. The flavors blend nicely up to 24 hours in advance.
