Ingredients Needed

For the Salad:

• 1 large English cucumber
• 2 large ripe avocados
• 1/2 medium red onion, finely diced
• 1/4 cup pepitas (pumpkin seeds)
• 1/2 cup cilantro, chopped

For the Dressing:

• 2 Tbsp lime juice, fresh
• 2 Tbsp extra virgin olive oil
• 1/2 tsp sea salt
• 1/4 tsp black pepper, freshly ground

Ingredient Notes & Substitutions

Cucumbers. I highly recommend using English or Persian cucumbers for this salad. They have thinner skin, fewer seeds, and a lower water content, which means your salad will be crisp and not watery.

Avocados. Look for avocados that yield to gentle pressure without feeling mushy. If they are firm to the touch, they are not yet ripe.

Cilantro. If you are not a fan of cilantro, you can easily substitute it. Fresh parsley or fresh dill would also be delicious in this salad.

Lime Juice. Freshly squeezed lime juice is a must. The bright, zesty flavor from fresh limes is far superior to the bottled kind and truly makes the dressing pop.

How to Make Cucumber Avocado Salad

Step 1: Toast the Pepitas

Begin by toasting the pepitas. Place them in a small, dry skillet over medium heat. Toast for 3 to 5 minutes, shaking the pan frequently, until they are fragrant and lightly golden. Remove them from the heat and set them aside to cool completely. This step awakens their nutty flavor.

Step 2: Quick-Pickle the Onion

In a large serving bowl, combine the finely diced red onion, fresh lime juice, and sea salt. Give it a quick stir and let it sit for about 10 minutes while you prepare the other ingredients. This process, called macerating, softens the sharp bite of the onion and creates a flavorful base for our dressing.

Step 3: Prep the Veggies

While the onion is pickling, prepare the rest of your vegetables. Chop the English cucumber into bite-sized pieces. Halve the avocados, remove the pits, and dice the flesh. A great tip is to add the diced avocado to the bowl with the onion and lime juice right away. Gently toss to coat the avocado in the lime juice, which helps prevent it from browning. Finally, chop the fresh cilantro.

Step 4: Combine and Dress

Add the chopped cucumber and cilantro to the serving bowl with the avocado and onion mixture. Drizzle the extra virgin olive oil over everything and add the freshly ground black pepper.

Step 5: Final Toss and Serve

Gently fold all the ingredients together. I recommend using a rubber spatula to avoid mashing the creamy avocado chunks. Just before serving, fold in the cooled, toasted pepitas. This ensures they stay perfectly crunchy. For the best texture and color, serve the salad immediately.

The Ultimate Guide to Perfect Ingredients

How to Choose, Ripen, and Store Avocados

Choosing a perfect avocado can feel like a lottery, but I have some tips. A ripe avocado for this salad should yield slightly to firm, gentle pressure in the palm of your hand. It should not be mushy or have dents. If your avocados are rock hard, you can speed up ripening by placing them in a paper bag for a day or two. To store a whole, uncut avocado, keep it on the counter if it needs to ripen, or in the refrigerator if it’s already ripe. Once cut, prevent browning by storing it with the cut side down in an airtight container with a squeeze of lime juice.

Choosing the Best Cucumber for a Non-Watery Salad

The type of cucumber you use can make or break this salad. Standard slicing cucumbers have thick, waxy skin and large seeds, and they release a lot of water, which can lead to a soggy salad. English cucumbers are long and thin with a delicate skin that doesn’t require peeling and very small seeds. Persian cucumbers are similar but smaller. Both are fantastic choices because their lower water content ensures your cucumber avocado salad stays crisp and fresh.

Pro Tips & Troubleshooting

Pro Tips for Success

Dress Just Before Serving. To keep the cucumbers crisp and the avocado perfectly green, it is best to toss everything together right before you plan to eat.

Toss Gently. The key to a beautiful, chunky salad is to preserve the texture of the avocado. Use a large spoon or a rubber spatula to fold the ingredients together gently, rather than stirring vigorously.

Use Fresh Lime Juice. This is a tip I cannot stress enough. The vibrant flavor of fresh lime juice is essential for a truly delicious dressing. It’s a small step that makes a huge difference.

Don’t Skip the Salt. Salt does more than just season the salad. In this recipe, it helps to mellow the red onion and draws out the natural flavors of the cucumber and avocado.

Common Mistakes to Avoid

Mistake #1: Using the Wrong Cucumber. Using a standard, watery cucumber will result in a diluted dressing and a soggy salad. Stick with English or Persian varieties.

Mistake #2: Dressing it Too Early. If you dress the salad and let it sit for too long, the salt will draw water out of the cucumbers, and the avocado will begin to oxidize and turn brown.

Mistake #3: Over-Mixing. Enthusiastic stirring can turn your beautiful, chunky salad into something that resembles guacamole. Fold the ingredients gently to maintain their integrity.

Mistake #4: Not Enough Acid. The lime juice in this recipe is crucial. It not only provides bright flavor but its acidity is key to slowing down the browning of the avocado.

Serving & Storage

Serving Ideas

This versatile salad can be served in so many ways. It’s a refreshing side dish for grilled lemon herb salmon, grilled chicken, or steak. It also works as a fantastic fresh topping for fish tacos or piled onto nachos. You can serve it with tortilla chips as a chunky dip for an easy appetizer. To turn it into a light and healthy lunch, simply add some grilled shrimp or chickpeas, or try our healthy chickpea avocado salad.

Storage and Make-Ahead

This salad is definitely best enjoyed fresh. However, if you need to prepare it in advance, you can prep the components separately. The cucumber, cilantro, and toasted pepitas can be chopped and stored in separate airtight containers in the fridge. The dressing ingredients (lime juice, olive oil, salt, pepper) can be whisked and stored. When ready to serve, dice the avocado and combine everything.

To store leftovers, transfer the salad to an airtight container. Press a piece of plastic wrap directly onto the surface of the salad to minimize air contact before sealing the lid. It will keep in the refrigerator for up to one day, though the texture will be softer.

FAQ

How do you keep the avocado from turning brown?

The best way to keep the avocado green is to use acid. In this recipe, tossing the diced avocado immediately in the fresh lime juice helps significantly. For storing leftovers, pressing plastic wrap directly against the surface of the salad minimizes oxygen exposure and slows browning.

What is the best type of cucumber to use for this salad?

English or Persian cucumbers are the best choices. They are less watery and have thinner skins and smaller seeds than regular slicing cucumbers, which prevents the salad from becoming soggy.

Can I make this salad ahead of time?

It’s best served fresh, but you can prep the components ahead of time. Chop the cucumber and cilantro and toast the pepitas; store them in separate containers in the fridge. Combine the dressing ingredients. Just before serving, dice the avocado and gently toss everything together.

Can I make this salad keto-friendly?

Yes, this recipe is naturally very low in carbohydrates and is perfect for a keto diet. Avocado and extra virgin olive oil provide excellent sources of healthy fats, making this a satisfying and keto-friendly salad.

What can I use instead of cilantro?

If you have an aversion to cilantro, you can easily substitute it. Freshly chopped parsley or dill would be excellent alternatives and would complement the other flavors in the salad beautifully.
