Ingredients
For this vibrant Tomato Cucumber & Avocado Salad, you’ll need:
• 2 medium cucumbers (about 2 cups when diced)
• 1 pint cherry tomatoes (2 cups), halved
• 2 ripe avocados, diced into ¾-inch cubes
• ½ red onion, thinly sliced
• ¼ cup fresh cilantro, chopped (or fresh dill or parsley)
• 2 tablespoons extra virgin olive oil
• 1 tablespoon fresh lemon juice
• 1 clove garlic, minced (optional)
• ½ teaspoon sea salt
• ¼ teaspoon freshly ground black pepper
• ¼ teaspoon dried oregano (optional)
Choose English cucumbers for their thinner skin and fewer seeds, or peel regular cucumbers if preferred. For tomatoes, vine-ripened or heirloom varieties offer the best flavor in this avocado cucumber salad. The avocados should yield slightly to gentle pressure—firm enough to hold their shape when mixed but ripe enough to be creamy.
Pro Tips
Perfect Your Avocado Timing: The trickiest part of any Tomato Cucumber & Avocado Salad is getting the avocado just right. Add it last, just before serving, and toss gently to prevent mushiness. If preparing in advance, complete all other steps, refrigerate, then add the avocado right before serving. A light brush of lemon juice on avocado pieces can also help prevent browning.
Master the Texture Balance: For the ideal cucumber texture, slice them just before mixing into the salad. If using regular cucumbers with thicker skins and more seeds, consider peeling them and scooping out the seeds with a spoon first. For cherry tomatoes, halving them releases their juices which blend with the dressing to create more flavor depth in your avocado tomato cucumber salad.
Elevate with Temperature Control: For the most refreshing version of this salad, chill the cucumbers and tomatoes for at least 30 minutes before cutting. However, never refrigerate the avocados before using, as cold temperatures can affect their texture and flavor. This temperature contrast creates a more dynamic eating experience when the ingredients come together.

Instructions
Step 1: Prepare the vegetables
Start by washing all produce thoroughly under cold running water. Pat the cucumbers and tomatoes dry with a clean kitchen towel. For the cucumbers, trim both ends and slice them lengthwise, then cut into ½-inch half-moons or dice into cubes. If using regular cucumbers with thick skin, you might want to peel them first. Halve the cherry tomatoes, or if using larger tomatoes, core them and cut into 1-inch chunks. Thinly slice the red onion and place in a bowl of cold water for 5-10 minutes to reduce sharpness.
Step 2: Make the dressing
In a small bowl, whisk together the olive oil, fresh lemon juice, minced garlic (if using), salt, pepper, and dried oregano until well combined. The dressing should look slightly emulsified. Taste and adjust seasonings if needed—remember that the avocado will mellow the flavors when added.
Step 3: Prepare the avocados
Cut the avocados in half lengthwise around the pit. Remove the pit by carefully striking it with a knife and twisting. Score the flesh into cubes while still in the skin, then scoop out with a large spoon. Immediately drizzle with a little extra lemon juice to prevent browning.
Step 4: Combine and serve
In a large bowl, combine the cucumber, tomatoes, and drained red onion. Pour about three-quarters of the dressing over the vegetables and toss gently. Add the chopped cilantro (or alternative herbs) and mix again. Finally, add the avocado cubes and drizzle with the remaining dressing. Using two large spoons, gently fold the ingredients together to coat everything with dressing without mashing the avocado. Serve immediately for the freshest flavor and texture in your Tomato Cucumber & Avocado Salad.
Variations
Mediterranean Style: Transform your Tomato Cucumber & Avocado Salad by adding ½ cup crumbled feta cheese, a handful of pitted kalamata olives, and substituting the cilantro with fresh mint and parsley. This variation complements the existing ingredients while adding tanginess and saltiness that pairs beautifully with grilled meats or as part of a mezze platter.
Protein-Packed Version: Make this avocado cucumber tomato salad into a complete meal by adding protein. Toss in a cup of cooked quinoa or chickpeas for a vegetarian option, or add diced grilled chicken breast or flaked tuna for meat-eaters. The protein additions turn this side dish into a satisfying lunch that will keep you full for hours while maintaining all the fresh flavors of the original.
Spicy Southwest: Give your salad a kick by adding one diced jalapeño (seeds removed for less heat), ½ cup corn kernels (fresh or roasted), and a teaspoon of ground cumin to the dressing. This variation brings a wonderful Tex-Mex flavor profile that works beautifully as a topping for tacos or alongside grilled fish.
Storage and Serving
This Tomato Cucumber & Avocado Salad is best enjoyed fresh, within 2-3 hours of preparation. If you need to store leftovers, transfer them to an airtight container, place plastic wrap directly on the surface to minimize air exposure, and refrigerate for up to 24 hours. The avocado may darken slightly and the vegetables will release more water, but a quick stir and a splash of fresh lemon juice can revive the flavors.
For serving, try this fresh cucumber tomato salad alongside grilled proteins like chicken, fish, or shrimp for a complete summer meal. It also makes an excellent topping for toasted sourdough bread—spread a thin layer of goat cheese on the bread first, then pile the salad on top for an elevated open-faced sandwich.
For entertaining, serve this vibrant salad in a shallow, wide bowl to showcase its colorful ingredients, or use it as a filling for lettuce cups for an elegant finger food. Consider offering extra lemon wedges on the side for guests who enjoy a brighter, more acidic flavor profile.
FAQs
How do I keep avocados from turning brown in the salad?
The lemon juice in the dressing helps prevent browning, but for best results, add avocado just before serving. If preparing in advance, toss the avocado pieces separately in a little extra lemon juice before adding them to the salad.
Can I make this Tomato Cucumber & Avocado Salad ahead of time?
You can prepare all components except the avocado up to 4 hours ahead and refrigerate. Add the diced avocado just before serving for the freshest appearance and texture.
Is this salad keto-friendly?
Yes! This salad is naturally low in carbohydrates and high in healthy fats from the avocado and olive oil, making it perfect for keto diets.
What can I use instead of cilantro?
If you don’t enjoy cilantro, substitute with fresh parsley, dill, or basil. Each herb will give the salad a different flavor profile while maintaining its fresh character.
Can I add cheese to this salad?
Absolutely! Feta, goat cheese, or fresh mozzarella pearls make excellent additions to this Tomato Cucumber & Avocado Salad. The creamy, tangy notes of cheese complement the vegetables beautifully.
