Ingredients Overview

To make a salad this simple shine, you need to pay attention to the quality of your ingredients. Here is the breakdown of what you need:

The Main Trio

• English Cucumber: We specifically recommend English cucumbers (also known as hothouse cucumbers) for this recipe. They have thinner skin that doesn’t need peeling, fewer seeds, and a sweeter, less bitter flavor than standard field cucumbers. They provide the essential crunch.
• Avocado: You need ripe but firm avocados. If they are too mushy, they will disintegrate when you toss the salad, turning it into guacamole. Look for avocados that yield slightly to gentle pressure but don’t feel hollow.
• Feta Cheese: Buy a block of feta in brine and cube it yourself for the best texture. Pre-crumbled feta often has anti-caking agents that make it dry. Cubed feta holds its shape better in this chunky salad.

The Dressing & Aromatics

• Fresh Dill: Dried dill simply won’t do here. You need the feathery, aromatic punch of fresh dill weed. It cuts through the richness of the avocado and cheese.
• Extra Virgin Olive Oil: Use your good oil here. Since it isn’t being cooked, you will taste the grassy, peppery notes of a high-quality EVOO.
• Lemon Juice: Freshly squeezed is mandatory. The acidity brightens the flavors and helps prevent the avocado from browning too quickly.
• Salt & Black Pepper: Freshly cracked black pepper adds a nice heat, while sea salt enhances the natural flavors. Be mindful of the salt, as feta is already quite salty.

Kitchen Tools Needed

• Sharp Chef’s Knife: Essential for dicing the avocado and cucumber cleanly without crushing them.
• Cutting Board: A large workspace makes prep easy.
• Large Mixing Bowl: Glass is preferred for presentation.
• Small Whisk or Jar: To emulsify the dressing before pouring.
• Salad Servers: Gentle hands or wide spoons are best to toss the delicate avocado.

Step-by-Step Instructions

Step 1: Prep the Cucumber

Wash your English cucumber. You can leave the skin on for color and texture. Slice the cucumber lengthwise, then slice each half lengthwise again so you have four long quarters. Chop these into bite-sized chunks (about 1/2 inch thick). Place them in your large mixing bowl.

Step 2: Prep the Avocado

Cut the avocados in half carefully around the pit. Remove the pit and peel away the skin. Dice the avocado flesh into chunks that are roughly the same size as your cucumber pieces. Tip: Add the avocado to the bowl last, just before tossing, to keep it intact.

Step 3: Cube the Feta

Take your block of feta cheese and cut it into neat cubes. If you prefer a more rustic look, you can crumble it, but cubes offer a nice bite that matches the other ingredients. Add the feta to the bowl.

Step 4: Make the Dressing

In a small jar or bowl, combine the Extra Virgin Olive Oil, fresh lemon juice, salt, and black pepper. Whisk or shake vigorously until the mixture is emulsified and slightly creamy looking.

Step 5: Combine and Toss

Chop your fresh dill roughly. Add the dill and the dressing to the bowl with the vegetables and cheese. Using large spoons, gently fold the salad together. Do not over-mix, or the avocado will start to mash and coat the cucumber, making the salad look muddy. You want distinct, glossy pieces.

Step 6: Serve Immediately

This salad is best served right after tossing while the cucumber is crisp and the avocado is bright green.

Expert Tips for Success

The Avocado Window:
If you are making this for a party, you can chop the cucumber and feta ahead of time and keep them in the fridge. Do not cut the avocado until the very last minute to prevent oxidation (browning).

Draining the Cucumbers:
If you only have standard waxing cucumbers, peel them and scoop out the seeds with a spoon. You might also want to salt them lightly and let them sit in a colander for 10 minutes to draw out excess moisture so your salad doesn’t get watery.

Flavor Melding:
While fresh is best, letting the salad sit for just 10 minutes allows the lemon and oil to marinate the feta cheese, which is delicious. Just don’t wait too long!

Variations and Add-Ins

Add Protein:
Turn this side dish into a main meal by adding grilled shrimp, rotisserie chicken chunks, or even chickpeas for a vegetarian protein boost.

Mediterranean Twist:
Add halved cherry tomatoes and pitted Kalamata olives to lean harder into the Greek salad profile. Thinly sliced red onion also adds a nice sharp bite and beautiful purple color.

Herb Swap:
If you aren’t a fan of dill, fresh mint or parsley are excellent alternatives. Mint makes the salad taste even cooler, while parsley adds an earthy freshness.

Spice it Up:
A pinch of red pepper flakes in the dressing adds a subtle heat that contrasts wonderfully with the cooling cucumber and avocado.

Common Questions (FAQ)

Can I store leftovers?
Technically, yes, but this salad is best eaten fresh. The cucumber will release water over time, diluting the dressing, and the avocado will eventually brown despite the lemon juice. If you must store it, press plastic wrap directly onto the surface of the salad to minimize air contact and eat within 24 hours.

Is this salad Keto?
Yes! This is a fantastic Keto option. It is high in healthy fats from the avocado and oil, moderate in protein from the cheese, and low in net carbs.

Can I use dried dill?
We strongly advise against it. Dried dill has a very different, more concentrated flavor that doesn’t provide the same fresh “pop” as the fresh herb. If you can’t find dill, try fresh chives instead.

What if I don’t like Feta?
Small mozzarella pearls (bocconcini) make a great substitute if you want something milder. Goat cheese works too, but it will be much creamier and messier to toss.
