Ingredients
For the Salad
2 large red onions, very thinly sliced into half-moons or rings
½ cup fresh flat-leaf parsley, finely chopped
For the Dressing
2 tablespoons extra virgin olive oil
2 tablespoons fresh lemon juice
1 tablespoon ground sumac
½ teaspoon salt
¼ teaspoon freshly ground black pepper
Pinch of red pepper flakes (optional)
Optional Garnishes
Fresh mint leaves
Extra parsley
Thin lemon slices
Additional sumac for serving
Instructions
Peel the red onions and slice them as thinly as possible using a sharp knife or mandoline slicer.
Place the sliced onions into a large bowl and sprinkle with the salt.
Massage the onions gently with your hands for about 2 to 3 minutes. This helps soften their texture and reduces their sharpness while encouraging them to release some moisture.
Pour the fresh lemon juice over the onions and toss well. Allow them to rest for about 20 minutes so they lightly pickle and absorb the citrus flavor.
While the onions are resting, finely chop the fresh parsley.
After the onions have softened, drain off any excess liquid if necessary.
Add the chopped parsley, ground sumac, black pepper, and red pepper flakes if using.
Drizzle the olive oil over the salad and toss everything together until evenly coated.
Taste and adjust the seasoning by adding additional salt, lemon juice, or sumac according to your preference.
Transfer the salad to a serving bowl and garnish with extra parsley, fresh mint leaves, lemon slices, and an additional sprinkle of sumac for a colorful finish.
Serve immediately or refrigerate for 15 to 30 minutes before serving for an even more developed flavor.
Tips
Slice the onions as thinly as possible for the best texture and flavor.
Massaging the onions with salt helps reduce their sharp bite without removing their natural crunch.
Freshly squeezed lemon juice provides a brighter flavor than bottled juice.
High-quality extra virgin olive oil makes a noticeable difference in the dressing.
Allowing the salad to rest before serving gives the flavors time to blend.
Ground sumac adds a unique tangy flavor that defines this salad.
Fresh parsley should be chopped just before mixing to preserve its vibrant color.
If the onions are especially strong, rinse them briefly in cold water before dressing.
Serve the salad chilled for maximum freshness.
Store leftovers in an airtight container for the best flavor and texture.
Variations
Add thinly sliced cucumbers for extra crunch.
Mix in halved cherry tomatoes for sweetness and color.
Include crumbled feta cheese for a creamy Mediterranean twist.
Add sliced radishes for additional crispness.
Mix fresh dill or mint with the parsley for extra herbal flavor.
Replace lemon juice with red wine vinegar for a slightly deeper tang.
Add toasted pine nuts or almonds for crunch.
Include thinly sliced bell peppers for extra sweetness.
Mix in cooked chickpeas for a heartier salad.
Top with pomegranate seeds for a sweet and colorful finish.
Q&A
Can I prepare this salad ahead of time?
