Ingredients
For the Salad
- 2 large ripe avocados, cut into bite-sized chunks
- 1 large English cucumber, about 10 oz (285 g), chopped
- 2 cups (300 g) cherry tomatoes, halved
- 1/3 small red onion, thinly sliced
- 1/3 cup (15 g) fresh cilantro leaves, roughly chopped
- 3 tablespoons (30 g) pumpkin seeds
- 1 tablespoon (9 g) sesame seeds
For the Zesty Herb Dressing
- 3 tablespoons (45 ml) extra virgin olive oil
- 2 tablespoons (30 ml) fresh lime juice
- 1 teaspoon (5 ml) honey
- 1 small garlic clove, finely minced
- 2 tablespoons (8 g) finely chopped fresh cilantro
- 1/2 teaspoon (1 g) dried oregano
- 1/2 teaspoon (3 g) kosher salt
- 1/4 teaspoon (1 g) freshly ground black pepper
Step-by-Step Instructions
- Prepare the cucumber. Wash and dry the cucumber, then cut it into chunky bite-sized pieces. Keeping the pieces relatively thick gives the finished salad the crisp texture shown in the dish.
- Prepare the tomatoes and onion. Halve the cherry tomatoes and thinly slice the red onion. For a milder onion flavor, soak the slices in cold water for 5–10 minutes, then drain and pat dry.
- Cut the avocado. Slice the avocados in half, remove the pits, and carefully scoop out the flesh. Cut into generous chunks similar in size to the cucumber pieces. Handle them gently to prevent mashing.
- Make the zesty herb dressing. Whisk together the olive oil, lime juice, honey, minced garlic, chopped cilantro, oregano, salt, and black pepper until glossy and well combined. Taste and add another splash of lime juice for extra brightness if desired.
- Combine the vegetables. Add the cucumber, cherry tomatoes, red onion, and cilantro to a large serving bowl. Pour over about two-thirds of the dressing and toss gently until evenly coated.
- Add the avocado. Fold in the avocado chunks using a large spoon or silicone spatula. Toss as little as possible so the avocado stays chunky and attractive rather than becoming mashed.
- Add the crunch. Sprinkle the pumpkin seeds and sesame seeds over the salad. Drizzle with the remaining dressing and finish with freshly cracked black pepper.
- Serve immediately. Let the salad rest for about 5 minutes so the vegetables absorb some of the dressing, then serve while the cucumber is crisp and the avocado is fresh.
Pro Tips
- Choose avocados that yield slightly when gently pressed but are still firm enough to cut into clean chunks.
- Use English or Persian cucumbers for their crisp texture and minimal seeds.
- Add the avocado after tossing the other vegetables to prevent it from breaking apart.
- Toast the pumpkin and sesame seeds briefly in a dry skillet for deeper, nuttier flavor.
- Use freshly squeezed lime juice for the brightest dressing.
- Wait until shortly before serving to add the dressing for maximum crunch and freshness.
Serving Suggestions
This avocado cucumber tomato salad makes a refreshing side for grilled chicken, roasted chicken, shrimp, salmon, white fish, steak, or lamb. For a light vegetarian lunch, serve it with chickpeas, quinoa, warm pita bread, or hummus. It also pairs beautifully with rice bowls, wraps, grilled vegetables, and summer barbecue dishes.
Storage
This salad tastes best immediately after preparation because avocado naturally softens and darkens over time. Store leftovers in an airtight container in the refrigerator for up to 1–2 days. Pressing a piece of food-safe wrap directly against the surface can help reduce exposure to air. A small squeeze of fresh lime juice will also help the avocado maintain its color. Freezing is not recommended.
FAQs
How do I keep the avocado from turning brown?
Coat the avocado well with the lime-based dressing and minimize its exposure to air. For meal prep, prepare the other ingredients ahead and cut the avocado shortly before serving.
Can I make this salad ahead of time?
You can prepare the cucumber, tomatoes, onion, seeds, and dressing several hours ahead. Keep them refrigerated separately, then add the freshly cut avocado and dressing just before serving.
What seeds work best in avocado cucumber salad?
Pumpkin and sesame seeds provide excellent crunch and match the salad especially well. Sunflower seeds are another easy alternative.
Can I add protein to make it a complete meal?
Yes. Grilled chicken, shrimp, salmon, tuna, chickpeas, or hard-boiled eggs can turn this fresh salad into a satisfying main meal.
