What are Sumac Onions?
Turkish sumac onions are thinly sliced red onions massaged with and marinated in sumac, olive oil, and lemon juice (sometimes red wine vinegar) to flavor and soften the onions.
Ingredients You’ll Need
- Onion: I prefer the sharpness of red onion, but you can also use white or yellow onion.
- Lemon Juice: Fresh lemon juice from one lemon is all you need for a nice pop of acidity. Other recipes rely on red wine vinegar or pomegranate molasses instead of lemon to provide tartness.
- Parsley: Fresh parsley adds color to the salad and compliments the flavor of the other ingredients.
- Spices: Season the onions with sumac and salt. Sumac is a popular Middle Eastern spice found online and in health stores. However, I recommend visiting a local Middle Eastern store to explore; the ground-up sumac berries give the dish its signature color and flavor.
- Olive Oil: Be generous with the olive oil; since it is a prominent ingredient, I recommend using high-quality olive oil if you can.
Additions and Substitutions
- Add a pinch of ground Aleppo pepper for even more flavor.

I've had these twice now and they are great! A healthy way to add so much flavor to a steak or lamb dish. I've had it over salad and shawarma now and it tastes very authentic.
