Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 cups thinly sliced red onions
2 tablespoons chopped fresh parsley
2 tablespoons extra virgin olive oil
2 tablespoons freshly squeezed lemon juice
2 tablespoons red wine vinegar
2 tablespoons sumac
½ teaspoon salt
½ teaspoon sugar
Optional additions:
¼ teaspoon red pepper flakes for heat
1 teaspoon pomegranate molasses for extra tanginess
Fresh mint or cilantro instead of parsley
Directions
Start by preparing the onions. Peel the red onions and slice them into thin, even strips using a sharp knife. Thin slices help the onions absorb the dressing more effectively while giving the salad its signature texture.
If your onions taste especially sharp or bitter, place the sliced onions in a bowl of cold water for about 15 minutes. Drain well and gently squeeze out the excess water before continuing. This simple step softens the onion flavor while keeping them crisp.
Add the sliced onions and chopped parsley to a medium mixing bowl.
Pour in the extra virgin olive oil, freshly squeezed lemon juice, and red wine vinegar. Sprinkle in the sumac, salt, and sugar.
Using clean hands, gently massage the onions for about 1 to 2 minutes. This step is important because it softens the onions slightly and helps the flavors blend together beautifully. As you massage the onions, they will turn a vibrant reddish-purple color from the sumac.
Cover the bowl and refrigerate the salad for at least 1 hour before serving. This resting time allows the onions to marinate and develop their full flavor.
Serve chilled or at room temperature alongside grilled chicken, kebabs, rice dishes, sandwiches, wraps, or roasted vegetables.
For a spicy version, add cayenne pepper or crushed red pepper flakes.
Swap parsley with fresh mint for a cooler and more refreshing flavor.
Add sliced cucumbers and tomatoes to transform the onions into a larger salad.
For a sweeter Middle Eastern-style variation, drizzle in a little pomegranate molasses.
You can also use white or yellow onions if red onions are unavailable, although red onions provide the best traditional flavor and color.
Try adding thinly sliced radishes for extra crunch and freshness.
Storage/Reheating
Store leftover sumac onions in an airtight container in the refrigerator for up to 3 days. The flavor becomes deeper and milder as the onions continue to marinate.
Before serving leftovers, stir the onions well to redistribute the dressing and seasonings.
This salad does not require reheating and is best served cold or at room temperature.
Avoid freezing, as the onions may lose their crisp texture once thawed.
