Quick Guide: How to Make Tomato Cucumber and Onion Salad
Grab the freshest tomatoes and cucumbers you can get your hands on, and whip up this easy salad up to one day ahead. The flavors shine on day two due to the marinated veggies in the tangy olive oil and red wine vinegar dressing. In summary, here’s how to make it (see recipe card for details):
- First, whip up the olive oil – red wine vinegar dressing.
- Second, slice the cherry tomatoes in half.
- Third, scrape the seeds from the cucumber and slice the cucumber into chunks.
- Next, slice the red onion into half moons.
- Last, pour dressing over the veggies, add a few twists of black pepper and toss.
Hang on to those cucumber seeds and their juices. They’re so refreshing in a green smoothie!
PRO TIP: If the red onions have a sharp taste, you can soak them, sliced, in ice water for about 10 minutes prior to adding them to your recipe. This mellows their flavor yet retains crunch!

Good to Know
To Peel or Not to Peel
If the cucumber skin seems tough or thick, you can use a veggie peeler to remove the skin or remove it partially to create stripes. Or you can leave them on for added texture.
You Can Add….
This salad would be delicious with chickpeas, sunflower seeds or even hemp hearts sprinkled over the top.
Any Tomato for this Salad
Just about any fresh tomato will work in this salad. I like cherry tomatoes because of their sweetness, thin skin, and ease of handling (and they’re abundant in the garden right now). But grape, Roma, heirloom, or slicing tomatoes such as early girl or stupice work too.
Traci’s Tips
- Cucumbers: for this cucumber onion tomato salad, I like using Kerby or garden cucumbers, the variety you typically find at the grocery store. Thinned skinned English or Persian cucumbers will work too.
- Cucumber Seeds: We’re scraping the seeds out to control water content in this salad. However, they’re fabulous in smoothies! Store the seeds and juice in the fridge for a few days until you’re ready to use them.
- Make Ahead: This tomato cucumber salad can be enjoyed shortly after making, however day two is when its flavor really stands out. The marinated cucumber is such a nice surprise!
- Fresh Herbs: Use your favorite fresh herbs here for maximum flavor. Dill, oregano and/or basil are quite nice.
