Ingredients You’ll Need

1 lb cherry tomatoes: Look for ripe, juicy tomatoes for the best flavor. If cherry tomatoes aren’t available, you can substitute with diced regular tomatoes.
1 large cucumber: A fresh cucumber adds crunch. English cucumbers are a great option since they’re less bitter and have fewer seeds.
1 small red onion: This adds a mild sweetness. If you prefer less bite, soak the slices in cold water for a few minutes before adding them to the salad.
A handful of fresh herbs (basil, dill, and parsley): Fresh herbs bring a depth of flavor. Feel free to mix and match based on your preferences or what you have on hand.
1/2 cup crumbled feta cheese: Adds a creamy, salty finish. If you want a dairy-free option, omit it entirely or use a vegan crumbly cheese.
3 tbsp olive oil: A quality extra virgin olive oil is best for flavor. You can substitute with any light oil, but it may change the taste slightly.
1 tbsp red wine vinegar: This adds a tangy kick. Apple cider vinegar or lemon juice can be used as alternatives.
1 tbsp Dijon mustard: Helps emulsify the dressing and provides a subtle flavor. You can swap it for whole grain mustard for a different texture.
1/2 tsp dry oregano: A classic seasoning that complements the salad’s flavors. Fresh oregano is an excellent alternative if you have it.
Salt and ground pepper to taste: Essential for bringing all the flavors together. Adjust based on your preference!

How to Make Tomato Cucumber Onion Salad

Prepare the Vegetables: Slice the cucumber into thin half-moons, thinly slice the red onion, and halve the cherry tomatoes. Add all the vegetables to a large serving bowl.
Add Fresh Herbs: Chop the fresh herbs and gently toss them with the vegetables to combine.
Make the Dressing: In a small jar, add 3 tablespoons of olive oil, 1 tablespoon of red wine vinegar, 1 tablespoon of Dijon mustard, 1/2 teaspoon of dried oregano, and a pinch of salt and black pepper. Shake the jar until the dressing is well emulsified.
Combine Salad and Dressing: Place the salad in a serving dish and top with 1/2 cup of crumbled feta cheese. Pour the dressing over the salad and gently toss until all the vegetables are coated.
Let it Rest: Allow the salad to sit for 10–15 minutes before serving. This resting time will help the flavors meld together beautifully. Toss again before serving, and adjust seasoning if needed. Serve chilled or at room temperature.

Storing & Reheating

To keep your Tomato Cucumber Onion Salad fresh, store it in an airtight container in the refrigerator for up to 3 days. If you’re planning to enjoy it later, consider keeping the dressing separate until you’re ready to serve, as this will prevent the vegetables from becoming soggy. Freezing is not recommended for this salad since the texture of the cucumbers and tomatoes will change upon thawing. When ready to eat, you can simply enjoy it cold or at room temperature for the best flavor!

Chef’s Helpful Tips

Always use fresh, ripe vegetables for the best flavor and texture.
If your red onion’s flavor is too strong, soak the slices in cold water for a few minutes.
Adjust the seasoning based on your taste preference—more vinegar for extra tang or additional herbs for extra freshness.
Feel free to experiment by adding other vegetables, such as bell peppers or radishes, for added crunch.
This salad is best enjoyed fresh, but you can make it in advance for gatherings by preparing all the ingredients separately and combining them shortly before serving.
