Cucumber Tomato Onion Salad

Cucumber Tomato Salad is my absolute favorite summer salad. Fresh cucumbers, summer tomatoes, shallots and a quick vinaigrette make this perfect for all of your summer cookouts. 

Every summer growing up our family would host lots of BBQs and summer cookouts. Of course hot dogs, burgersgrilled chicken and spicy pepper steak were staples. But one of the things that I looked forward to the most was my mom’s Cucumber Tomato Onion Salad.

Cucumber Tomato Salad is my absolute favorite summer salad. Fresh cucumbers, summer tomatoes, shallots and a quick vinaigrette make this perfect for all of your summer cookouts. 

The way that mom would traditionally make this salad was to dice tomatoes, cucumbers and red onions. Then she would pour Italian dressing over the top and let the the whole salad marinate for a few hours in the refrigerator.

Over the years I have made this cucumber tomato salad my own by making a few small changes.

INGREDIENTS:

This recipe is essentially split in two: The salad ingredients and the vinaigrette.

  • CUCUMBERS: You can use common cucumbers or english cucumbers. If you use English cucumbers feel free to leave the peel on.
  • TOMATOES: Vine ripened tomatoes are my favorite in this because they have the best flavor.
  • SHALLOTS: I like to use shallots in this recipe because they are a bit more mild than the traditional red onion. If you’d like even more mild onion flavor, use a white onion.

To make the vinaigrette you’ll need:

  • EXTRA VIRGIN OLIVE OIL: I like to use extra virgin olive oil in vinaigrettes because it is more flavorful than other oils.
  • RED WINE VINEGAR: It is sharp and tangy. It also has a bit more flavor than white vinegars.
  • WATER
  • OREGANO AND BASIL: I use dried in vinaigrettes because they seem to hold up a bit better.
  • SALT AND PEPPER
  • GARLIC: Since it’s fresh be sure to chop it small so that you don’t get whole bites of raw garlic in your salad.

How to make cucumber tomato salad:

  • 1. The dressing. My mom would use a bottle of our favorite Italian dressing and it was always good. I don’t usually have it on hand but it is really easy to make your own vinaigrette. All you need is red wine vinegar, extra virgin olive oil, water, garlic and a few seasonings.
  • 2. The cucumber. I prefer english cucumbers. They are the long cucumbers that you find usually wrapped in plastic at the grocery store. They are seedless, often less bitter and they don’t need to be peeled. Although you can peel them if you like. With that said, a regular cucumber would be just fine.
  • 3. The tomatoes. Obviously, fresh summer tomatoes shine in this recipe. You’ll want tomatoes that are large and firm.
  • 4. The onion. My mom would make this salad using diced red onions. And while I loved the salad, I do remember leaving the onions on the plate more often than not. For this cucumber salad recipe, I use thinly sliced shallots instead. You will still get a subtle oniony flavor but they aren’t overpowering.
  • 5. Waiting. That’s the hardest part. This salad is best when it’s allowed to marinate for at least a few hours in the fridge, even better the next day. I usually let it set at room temperature an hour or so before serving too which makes it even better.
