Ingredients

2 large red onions, thinly sliced
1 tablespoon sumac, plus extra for garnish
1/4 cup fresh lemon juice
3 tablespoons extra virgin olive oil
2 tablespoons fresh parsley, finely chopped
1/2 teaspoon salt, adjust to taste
1/4 teaspoon freshly ground black pepper
Optional: pinch of chili flakes for heat

Instructions

Prepare the onions: Peel and thinly slice the red onions into half-moon shapes. For a milder taste, soak them in cold water for 10 minutes, then drain thoroughly.
Mix the dressing: In a small bowl, whisk together sumac, lemon juice, olive oil, salt, and pepper until well combined.
Combine ingredients: Place the sliced onions in a large mixing bowl. Pour the dressing over the onions and toss to coat evenly.
Add herbs: Sprinkle chopped parsley over the salad and gently mix again to distribute.
Chill (optional): For a deeper flavor, cover the salad and refrigerate for 15–30 minutes before serving.
Serve and garnish: Transfer to a serving bowl or plate. Sprinkle a little extra sumac and parsley on top for color and flavor. Add chili flakes if desired.

Tips for the Perfect Sumac Onion Salad

Use fresh sumac: The key to authentic flavor lies in using freshly ground sumac; avoid pre-mixed spice blends for a purer tang.
Balance acidity: Taste the salad before serving and adjust lemon juice or salt to your preference.
Mellow the onions: Soaking onions in ice water reduces their sharpness while keeping the crunch.
Serve immediately or later: The salad tastes best fresh, but it can hold in the fridge for up to 24 hours.

Variations

Add tomatoes or cucumbers: For a refreshing twist, toss in diced cucumbers or cherry tomatoes.
Herb enhancements: Experiment with mint, cilantro, or dill for added aroma.
Nutty crunch: Top with toasted pine nuts or walnuts to add texture.
Spicy kick: Incorporate finely diced fresh chili or a sprinkle of paprika for heat.

Serving Suggestions

With grilled meats: Perfect alongside lamb, chicken, or beef kebabs.
With flatbreads: Serve as a topping for pita or lavash for a tangy crunch.
As part of a mezze platter: Combine with hummus, baba ganoush, and olives for a Middle Eastern spread.
Salad bowl combo: Mix with other fresh greens and grains for a light lunch option.
