Ingredients

For this vibrant Tomato Cucumber Avocado Salad with Mozzarella and Basil Pesto, you’ll need:

• 2 cups (300g) cherry tomatoes, halved (or 4 medium tomatoes, diced)
• 1 large English cucumber (about 12 oz/340g), diced
• 2 medium ripe avocados, pitted and cubed
• 8 oz (225g) fresh mozzarella pearls (or ball mozzarella, torn into bite-sized pieces)
• ¼ cup (10g) fresh basil leaves, torn or thinly sliced
• 3 tablespoons basil pesto (store-bought or homemade)
• 2 tablespoons extra-virgin olive oil
• 1 tablespoon fresh lemon juice
• 1 garlic clove, minced
• ½ teaspoon sea salt
• ¼ teaspoon freshly ground black pepper
• Optional: 2 tablespoons pine nuts for garnish

Choose perfectly ripe avocados that yield slightly to pressure but aren’t mushy. For the best flavor, opt for fresh mozzarella packed in water rather than pre-shredded varieties.

Pro Tips

Use room temperature ingredients: For the best flavor in your Tomato Cucumber Avocado Salad, remove the mozzarella and pesto from the refrigerator about 30 minutes before assembling. Cold ingredients mute flavors, while room temperature components allow the full spectrum of tastes to shine through.

Perfect your pesto technique: If making homemade pesto, toast your pine nuts first for deeper flavor. For the smoothest emulsion, add olive oil gradually while the food processor is running. If you’re using store-bought pesto, choose one without preservatives for a fresher taste, or enhance it with a squeeze of lemon and extra fresh basil.

Master the avocado timing: Add your avocado last to prevent browning. If preparing the salad in advance, toss the cucumber and tomato components with the dressing, but wait to add the avocado and mozzarella until just before serving. You can also brush the cut avocado with a little lemon juice to maintain its vibrant green color longer.

Instructions

Step 1: Prepare the vegetables

Start by washing all your produce thoroughly under cool running water. Pat dry with a clean kitchen towel. Halve the cherry tomatoes (or dice larger tomatoes into ¾-inch pieces), aiming for bite-sized pieces that will marry well with the other ingredients. For the cucumber, slice it lengthwise and scoop out the seeds with a spoon if they’re particularly watery, then dice into similar-sized pieces as the tomatoes. This uniform cutting ensures you get a perfect balance of flavors in each bite of your Tomato Cucumber Avocado Salad.

Step 2: Prepare the mozzarella and herbs

If using a large ball of fresh mozzarella, tear it into bite-sized pieces rather than cutting it – the irregular edges hold more dressing and create better texture. For mozzarella pearls, simply drain them well. Stack your basil leaves, roll them tightly like a cigar, then slice thinly to create delicate ribbons (chiffonade). Set aside a few pretty basil leaves for garnishing the finished salad.

Step 3: Make the pesto dressing

In a small bowl, combine the basil pesto with extra-virgin olive oil, fresh lemon juice, and minced garlic. Whisk until smooth and well integrated. This thinned pesto creates the perfect consistency for coating all the salad ingredients while intensifying the basil flavor that makes this Tomato Cucumber Avocado Salad with Mozzarella and Basil Pesto so distinctive.

Step 4: Combine and serve

In a large bowl, gently combine the tomatoes, cucumber, and mozzarella. Pour about three-quarters of the pesto dressing over these ingredients and toss gently. Just before serving, carefully fold in the diced avocado to prevent it from becoming mushy. Drizzle the remaining dressing over the top, sprinkle with salt and freshly ground black pepper, and garnish with the reserved basil leaves and optional pine nuts. Serve immediately for the freshest flavor and most beautiful presentation.

Variations

Mediterranean-Style Avocado Pesto Salad: Transform this Tomato Cucumber Avocado Salad by adding 1/2 cup of pitted kalamata olives, 1/4 cup of thinly sliced red onion, and crumbling 1/3 cup of feta cheese in place of the mozzarella. This variation adds briny, tangy notes that complement the creamy avocado and basil pesto beautifully. Finish with a sprinkle of dried oregano for an authentic Mediterranean touch.

Protein-Packed Pesto Salad Bowl: Turn this side dish into a complete meal by adding protein. Toss in 2 cups of cooked, chilled quinoa and 1 cup of drained, rinsed chickpeas or white beans. The nutty flavor of the quinoa pairs wonderfully with the basil pesto, while the beans add heartiness and extra nutrition. For meat lovers, adding 6 ounces of grilled chicken breast or shrimp works perfectly with the fresh flavors of this avocado cucumber tomato salad.

Dairy-Free Avocado Tomato Salad: Create a vegan version by omitting the mozzarella and using a dairy-free pesto (made with nutritional yeast instead of Parmesan). Add an extra avocado for more creaminess, and consider including 1/4 cup of toasted sunflower seeds for texture and protein. This adaptation maintains all the fresh, vibrant qualities of the original while accommodating plant-based diets.

Storage and Serving

This Tomato Cucumber Avocado Salad with Mozzarella and Basil Pesto is best enjoyed immediately after assembly, as the avocado will begin to oxidize and the vegetables will release water over time. However, if you need to store leftovers, place them in an airtight container with a piece of paper towel to absorb excess moisture, and consume within 24 hours.

For make-ahead convenience, prepare all components separately and store them in individual containers in the refrigerator: the dressing, the cucumber and tomatoes, and the mozzarella. Keep the avocado whole until ready to serve, then cut and add it along with the other ingredients just before serving.

Serve this vibrant salad alongside grilled chicken or fish for a complete meal, or pair it with crusty artisan bread to soak up the flavorful pesto dressing. For an elegant appetizer presentation, spoon individual portions onto butter lettuce leaves or serve in small glass bowls with demitasse spoons for a sophisticated first course at dinner parties.

FAQs

Can I make this avocado pesto salad ahead of time?
You can prepare most components up to 24 hours ahead. Combine the tomatoes, cucumber, and mozzarella with the dressing, but add the avocado just before serving to prevent browning. Store covered in the refrigerator.

How do I keep the avocado from turning brown?
The lemon juice in the dressing helps prevent browning, but for best results, add the avocado last, just before serving your Tomato Cucumber Avocado Salad with Mozzarella and Basil Pesto.

Is this salad gluten-free?
Yes, this Tomato Cucumber Avocado Salad is naturally gluten-free. Just verify that your store-bought pesto doesn’t contain any gluten-containing additives.

Can I use different types of tomatoes?
Absolutely! While cherry tomatoes hold their shape well, you can use any ripe, flavorful tomatoes. Heirloom varieties add beautiful color variation, and Roma tomatoes work well because they’re less watery.

What can I substitute for fresh mozzarella?
If you can’t find fresh mozzarella, you can use feta cheese, goat cheese, or even small cubes of provolone. Each will provide a different flavor profile but will complement the other ingredients in your avocado tomato salad.
