Equipment Needed
- Large mixing bowl
- Small bowl or jar (for dressing)
- Whisk or fork
- Sharp knife and cutting board
- Measuring cups and spoons
Ingredients You’ll Need
For the Salad:
- 2 large cucumbers, diced
- 2 ripe avocados, diced
- ½ small red onion, thinly sliced
- ¼ cup fresh cilantro, chopped
- ¼ cup fresh dill, chopped (or 2 teaspoons dried)
- 2 tablespoons fresh parsley, chopped
- ¼ cup cherry tomatoes, halved (optional)
For the Lemon Dressing:
- 3 tablespoons olive oil
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- 1 clove garlic, minced
- ½ teaspoon Dijon mustard
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Pinch of sugar (optional)
Step-by-Step Instructions
Prepare Cucumbers: Wash cucumbers. If they have thick or waxy skin, peel them. Otherwise, leave skin on for color and texture.
Dice into ½-inch cubes. If cucumbers are very seedy, scoop out the seeds with a spoon.
Prepare Avocados: Cut avocados in half, remove pit, and scoop out flesh. Dice into ½-inch cubes.
Handle gently—avocado bruises easily.
Prepare Onion: Slice red onion very thinly into half-moons or small dice.
For a milder flavor, soak sliced onion in ice water for 5 minutes, then drain and pat dry.
Chop Herbs: Roughly chop fresh cilantro, dill, and parsley.
Fresh herbs are essential for this salad—dried don’t provide the same brightness.
Make Dressing: In a small bowl or jar, combine olive oil, lemon juice, lemon zest, minced garlic, Dijon mustard, salt, pepper, and sugar if using.
Whisk vigorously until emulsified, or shake the jar until well combined.
Combine Salad: In a large bowl, gently combine cucumbers, avocados, red onion, cherry tomatoes if using, and fresh herbs.
Be gentle to avoid mashing the avocado.
Dress Salad: Drizzle dressing over salad. Toss very gently to coat, being careful not to break up the avocado.
Use a light hand—over-mixing makes a mushy salad.
Taste and Adjust: Taste and adjust seasoning. May need more lemon, salt, or pepper.
The salad should be bright, fresh, and well-balanced.
Serve: Serve immediately for the best texture and flavor. Avocado browns quickly once cut.
Can chill briefly, but best served at room temperature or slightly cool.
Optional Additions: Just before serving, you can add feta cheese, sunflower seeds, or extra herbs.
Keep it simple—the cucumber and avocado should shine.

Ingredient Substitutions
Cucumbers: English cucumbers, Persian cucumbers, or zucchini ribbons.
Avocados: Must use ripe avocados. No good substitute.
Cilantro: Basil or mint creates a different but delicious flavor.
Dill: Fresh basil, tarragon, or extra cilantro.
Lemon Juice: Lime juice creates a slightly different citrus flavor.
Red Onion: Shallots, green onions, or white onions.

Storage
Best Fresh: This salad is truly best enjoyed immediately after making.
Short Storage: Can refrigerate up to 2 hours before serving.
Prevent Browning: Squeeze extra lemon juice over avocado to slow browning.
Store Components Separately: Prep cucumbers and dressing ahead, add avocado just before serving.
Not Freezer-Friendly: Neither cucumbers nor avocados freeze well.
Variations to Try

Common Mistakes to Avoid
Unripe Avocados: Hard avocados won’t work. Must be ripe and creamy.
Overmixing: Turns avocado mushy. Toss gently.
Making Too Far Ahead: Avocado browns, and cucumbers get watery.
Skipping Fresh Herbs: Essential for flavor. Don’t use dried.
Too Much Dressing: Should enhance, not drown. Start with less.
Watery Cucumbers: If cucumbers are very seedy, scoop out seeds.
Not Seasoning Enough: Needs a good amount of salt to bring out flavors.
