Ingredients
- 2 large English cucumbers, diced
- 1 pint cherry or grape tomatoes, halved
- 2 ripe avocados, diced
- 1/2 red onion, thinly sliced (optional, for sharpness)
- 1/4 cup fresh parsley, chopped
- 3 tablespoons freshly squeezed lemon juice
- 2 tablespoons extra virgin olive oil
- 1 teaspoon dried oregano
- 1/2 teaspoon salt (or to taste)
- 1/4 teaspoon black pepper (or to taste)
Step-by-Step Instructions
- Prepare the Vegetables: Wash and dice the cucumbers. Halve the cherry or grape tomatoes. If using, thinly slice the red onion. Dice the avocados last to minimize browning. Place all prepared vegetables and the chopped parsley into a large mixing bowl.
- Whisk the Dressing: In a small bowl, whisk together the freshly squeezed lemon juice, extra virgin olive oil, dried oregano, salt, and black pepper until well emulsified.
- Dress the Salad: Pour the dressing evenly over the vegetables in the large bowl.
- Toss Gently: Very gently toss the salad until all the vegetables are lightly coated with the dressing. Be careful not to over-mix, as this can mash the avocado.
- Taste and Adjust: Taste the salad and adjust seasoning if necessary, adding more salt, pepper, or a squeeze of extra lemon juice if desired.
- Serve Immediately: For the best texture, serve the Cucumber Tomato Avocado Salad within 30 minutes of preparation.
Expert Tips / Pro Tips
Using English or Persian cucumbers is highly recommended because they have fewer seeds and thinner skins, meaning less prep work for you. Always add the diced avocado just before you plan to serve the salad, as it oxidizes (browns) quickly once cut. If you must chop the avocados ahead of time, toss them immediately in a small amount of the lemon juice to help slow the browning process. When slicing red onion, rinse them under cold water after slicing to mellow their sharp flavor without eliminating the desired crunch.
Variations & Substitutions
For added texture, consider adding 1/2 cup of crumbled feta cheese or small mozzarella balls (bocconcini) to make this a more substantial dish. To introduce a gentle heat, include a pinch of red pepper flakes in the vinaigrette. Basil pairs wonderfully with tomatoes; try substituting half of the parsley with fresh basil. If you prefer a different acid, feel free to substitute the lemon juice with red wine vinegar or white wine vinegar, adjusting the salt slightly as needed.
Serving Suggestions
This Cucumber Tomato Avocado Salad shines as a bright side dish for grilled proteins like chicken, salmon, or steak. It is also an excellent accompaniment to vegetarian main courses, such as veggie burgers or halloumi cheese. For a light lunch, serve it atop a bed of crisp mixed greens or alongside whole-grain pita bread for dipping up the flavorful dressing.
Storage, Freezing & Reheating
This salad is best eaten fresh. Due to the high water content of the cucumbers and tomatoes, and the delicate texture of the avocado, this Cucumber Tomato Avocado Salad does not store well once dressed. If you must store leftovers, place them in an airtight container in the refrigerator for no more than 24 hours. Note that the texture will become softer, and the avocados may darken. Freezing is not recommended as the structure of the vegetables will break down entirely upon thawing.

FAQ
How do I stop the avocados from turning brown?
The acid in the dressing (lemon juice) helps inhibit oxidation. Make sure the diced avocados are tossed immediately with the dressing, ensuring they get a good coating of the lemon juice. If you are prepping ahead, place the avocado pieces in a separate, small bowl and toss them with just a teaspoon of lemon juice before gently folding them into the main salad just before serving.
Can I make this salad vegan?
Yes, the classic Cucumber Tomato Avocado Salad recipe as written is naturally vegan. It contains only fresh vegetables, herbs, and a simple oil and lemon dressing.
What kind of tomatoes work best?
Cherry tomatoes or grape tomatoes are ideal because they hold their shape well when tossed with dressing and minimal slicing is required. If you use larger tomatoes (like beefsteak), be sure to scoop out the watery seeds before dicing them to avoid a soggy salad.
