Why You’ll Love This Recipe

This Cucumber Avocado Salad will quickly become a staple in your recipe collection for so many reasons. First, it’s incredibly versatile—perfect as a refreshing side dish for grilled meats, a light lunch, or even as a topping for tacos. The contrasting textures are what make this salad truly special: the crisp, watery crunch of fresh cucumbers against the creamy, rich avocado creates a satisfying mouthfeel with every bite.

It’s the perfect solution for hot summer days when you want something fresh and nourishing without heating up the kitchen. The simple preparation lets the quality of each ingredient shine through.

Ingredients

For this refreshing Cucumber Avocado Salad, you’ll need:

• 2 large cucumbers (about 2 cups when sliced), English or Persian preferred
• 2 ripe avocados, medium-sized
• 1/4 cup red onion, thinly sliced
• 1/4 cup fresh cilantro, roughly chopped (optional: substitute with fresh dill or parsley)
• 2 tablespoons extra virgin olive oil
• 1 tablespoon fresh lime juice (about 1 medium lime)
• 1 small garlic clove, minced (optional)
• 1/2 teaspoon sea salt
• 1/4 teaspoon freshly ground black pepper
• 1/4 teaspoon ground cumin (optional)
• 1 jalapeño, seeded and finely diced (optional for heat)

The key to this cucumber and avocado blend is using ripe but firm avocados—they should yield slightly to gentle pressure but not be mushy. English cucumbers are recommended for their thin skin and fewer seeds, but any variety will work. The lime juice not only adds flavor but helps prevent the avocados from browning too quickly.

Pro Tips

1. Cucumber Preparation
For the best texture in your Cucumber Avocado Salad, consider partially peeling the cucumbers in alternating strips for visual appeal and a varied texture. If using regular cucumbers (rather than English), remove the seeds by cutting them in half lengthwise and scooping out the center with a spoon. This prevents excess moisture from making your salad watery. For extra crispness, place sliced cucumbers in a colander, sprinkle with a bit of salt, and let sit for 15 minutes to draw out excess moisture before patting dry.

2. Avocado Selection and Handling
Timing is everything with avocados. For this salad, choose avocados that yield slightly to pressure but aren’t too soft. If your avocados are underripe, place them in a paper bag with a banana overnight to speed up ripening. Add your avocado as the final ingredient just before serving to minimize browning. If preparing in advance, toss the avocado pieces in a little extra lime juice before adding to the salad.

3. Dressing Technique
For the most flavorful Cucumber Avocado Salad, make the dressing in a separate bowl and allow the garlic and spices to meld with the oil and lime juice for about 5 minutes before adding to the vegetables. This “blooms” the spices and mellows the garlic. For a creamier variation, reserve half an avocado and blend it with the dressing ingredients for a rich, velvety coating that clings to every piece of cucumber.

Instructions

Step 1
Prepare the cucumbers by washing them thoroughly. If using English cucumbers, you can leave the skin on; for regular cucumbers, peel partially or completely based on preference. Slice the cucumbers into 1/4-inch thick half-moons or quarter them for larger pieces. If your cucumbers have many seeds, halve them lengthwise and scoop out the seeds with a spoon before slicing.

Step 2
Slice the red onion as thinly as possible—using a mandoline if you have one—and soak in cold water for 5-10 minutes to reduce their sharpness. This quick step makes a big difference in the overall flavor balance of your Cucumber Avocado Salad, making the onions crisp but less pungent.

Step 3
In a small bowl, whisk together the olive oil, fresh lime juice, minced garlic (if using), salt, pepper, and cumin until well combined. The dressing should emulsify slightly. Taste and adjust seasonings as needed—you might want more lime juice for tang or more salt depending on your preferences.

Step 4
Cut the avocados in half, remove the pits, and carefully slice them in their skins in a cross-hatch pattern. Use a large spoon to scoop the flesh directly into your salad bowl in cubes. This technique helps maintain the avocado’s shape better than cutting on a board.

Step 5
Gently combine the cucumber slices, drained red onion, and avocado chunks in a large bowl. Pour the dressing over the vegetables and add the chopped cilantro. Fold everything together using a rubber spatula or wooden spoon, being careful not to mash the avocado pieces. Your goal is to coat every component with dressing while maintaining the distinct textures that make this avocado cucumber salad so appealing.

Step 6
For the best flavor, let the salad rest for about 10 minutes before serving to allow the flavors to meld. This brief marination period transforms a good salad into a great one, as the cucumbers absorb some of the dressing while still retaining their signature crunch.

Variations

Mediterranean Style
Transform your Cucumber Avocado Salad into a Mediterranean delight by adding 1/2 cup crumbled feta cheese, 1/4 cup kalamata olives, and substituting fresh dill for the cilantro. Skip the cumin and jalapeño, and add 1 teaspoon of dried oregano to the dressing. This variation pairs beautifully with grilled fish or as part of a mezze platter with hummus and pita bread.

Protein-Packed Version
Turn this side salad into a complete meal by adding protein. Toss in 1 cup of cooked quinoa and a can of drained, rinsed black beans or chickpeas. The beans add a satisfying heartiness while complementing the existing flavors of the cucumber avocado combination. This variation keeps well for lunch meal prep when you store the dressing separately until ready to serve.

Asian-Inspired Twist
For an Asian-inspired version, substitute rice vinegar for the lime juice and add 1 teaspoon of sesame oil and 1 tablespoon of soy sauce to the dressing. Garnish with sesame seeds and sliced green onions instead of cilantro. Consider adding thinly sliced radishes for extra crunch and color. This variation makes an excellent side dish for grilled salmon or teriyaki chicken.

Storage/Serving

The Cucumber Avocado Salad is best enjoyed fresh, ideally within a few hours of preparation. If you need to store leftovers, place them in an airtight container with a piece of plastic wrap pressed directly onto the surface of the salad to minimize air exposure, which causes avocados to brown. Even with this method, expect the salad to keep for only about 24 hours in the refrigerator before the avocados begin to oxidize and the cucumbers release excess water.

For make-ahead preparation, combine all ingredients except the avocado and dressing up to 24 hours in advance. Store in the refrigerator, then add freshly cut avocado and dressing just before serving.

Serve this bright salad alongside grilled fish or chicken for a light dinner, or pair it with crusty bread and a glass of crisp white wine for a simple lunch. For an elegant presentation, serve individual portions in lettuce cups or on a bed of mixed greens. The Cucumber Avocado Salad also makes an excellent topping for grain bowls or as a fresh accompaniment to spicy dishes like blackened shrimp or chicken tacos.

FAQs

How do I keep the avocados from turning brown?
The lime juice in the dressing helps slow oxidation, but for maximum freshness, prepare the avocado last and add it just before serving. If making ahead, an extra squeeze of lime juice directly on the avocado pieces can provide additional protection.

Can I make this salad ahead of time?
It’s best to prepare the components ahead but assemble just before serving. You can slice the cucumbers and onions up to 24 hours in advance, but add the avocado and dressing right before serving for optimal texture and appearance.

What’s the best type of cucumber to use?
English or Persian cucumbers are ideal for this Cucumber Avocado Salad as they have thinner skins, fewer seeds, and less bitter flavor. However, regular garden cucumbers work fine if you peel them and remove the seeds.

Is this salad keto-friendly?
Yes! The Cucumber Avocado Salad is naturally low in carbohydrates and high in healthy fats, making it perfect for keto or low-carb diets.

How can I make this salad more filling?
Add protein sources like grilled chicken, shrimp, hard-boiled eggs, or chickpeas to transform this side dish into a complete meal. You can also bulk it up with cooked quinoa or farro for a heartier grain salad.
