Recipe Tips & Tricks

Drain thoroughly: After salting, make sure to fully drain the liquid from the cucumbers and tomatoes to prevent a watery salad
Cut evenly: Keep your cucumber and avocado pieces similar in size for better texture and balanced bites
Add avocado last: Always mix in the avocado right before serving to keep it from browning or getting mushy
Use fresh herbs: Fresh basil makes a big difference in flavor, so avoid dried herbs for this recipe
Shake dressing well: Emulsify the dressing for at least 10 to 15 seconds so it coats the salad evenly
Chill before serving: Let the finished salad sit in the fridge for 10 to 15 minutes for an extra refreshing taste

⭐ Confidence Tip: If you’re short on time, skip the resting step and just pat the cucumbers dry with a paper towel to reduce excess moisture quickly.

Storage & Reheating

Storage: Store the salad without avocado in an airtight container in the refrigerator for up to 3 days. Add freshly diced avocado just before serving for best texture and color
Reheating: No reheating needed. This cucumber tomato salad is best enjoyed cold or slightly chilled for maximum freshness
Freezing: Not recommended. The fresh vegetables and avocado will lose their texture and become mushy once thawed

Additions & Substitutions

Additions

Add a protein boost: Toss in chickpeas, white beans, or grilled chicken for a more filling meal
Spice it up: Sprinkle in red pepper flakes or a pinch of chili powder for a subtle kick
Extra crunch: Add thinly sliced red onion or chopped celery for more texture
Mediterranean twist: Top with olives and a sprinkle of oregano for a bold flavor variation
Creamy finish: Drizzle with tahini or add a spoonful of hummus on the side for a richer bite

Substitutions

Oil options: Substitute olive oil with avocado oil for a neutral, equally healthy fat
Swap the herbs: Use parsley, dill, or cilantro instead of basil depending on your taste
Change the vinegar: Apple cider vinegar or white wine vinegar works well in place of red wine vinegar
No lemon juice: Try lime juice for a slightly different citrus flavor in this tomato cucumber avocado salad
