These Sumac Onions are a Turkish marinated onion salad that are crisp and tangy and the perfect condiment to any dish. They take 10 minutes to make and taste amazing in sandwiches, kebabs, BBQs, and all Middle Eastern food.
I absolutely love Middle Eastern food and Turkish cuisine! When travelling to Dubai and the Middle East, you will find this condiment served at most restaurants. I love ordering sumac onions alongside mezze platters with hummus and falafels which all work so well together. I'm usually not a big fan of raw onions, but these don't have that harsh oniony taste at all. With only 5 ingredients and 10 minutes, you will have made the perfect condiment ready to go!
The superstar ingredient is the sumac which has a light citrusy taste. It helps cure the onions alongside the lemon juice and salt. The red onions are marinated in a light dressing which softens the harsh taste and gives it a light pickling, making them tangy and crisp and absolutely delicious! You can really serve them with any dish. I love adding them to sandwiches and wraps such as my falafel wrap, crispy feta egg wrap and chickpea tuna sandwich.
Having a Persian background, we also use sumac in many Persian recipes. We love topping Persian rice with sumac, especially when served with Persian kabob or also in mast o khiar which is a yogurt dip. You can also add sumac to salad dressings for the perfect tart and citrusy flavor.
The most common way that this sumac onion salad is served in Turkish and Middle Eastern cuisine is alongside kebabs, shawarma, grilled meats and BBQs. This crisp Turkish onion salad lightens and freshens the flavors and cuts through the heaviness of the meat, chicken or proteins. In saying that, you can also enjoy these sumac onions with fish and seafood and many vegetarian and plant based recipes. Some of my favorites are cauliflower steaks, crispy tofu and Persian kotlet patties.

What is Sumac?
Sumac is a Middle Eastern spice that come from dried, ground berries of the sumac plant. They are tiny red berries that grow on a sumac bush "Rhus coriaria".
The name relates to the Arabic word "summāq" which we also have in the Persian language farsi. It translates to the word “dark red”. The sumac color itself is a dark red color, more closer to burgundy.
In terms of flavor, sumac has a tangy, lemony, citrus flavor which is slightly sour with touches of earthiness. It gives a lovely acidic freshness to foods and is very popular in Middle Eastern cuisine including Turkish, Persian, Lebanese and many other cultures. You can add it to marinades, dressings and of course these sumac onions which pair well with many recipes.
Ingredients and Substitutions
- Sumac is the star of the show! Its a Middle Eastern spice with a citrusy, tart, lemony flavor that you can purchase at many supermarkets or your closest Middle Eastern store
- Red onion is my preferred onion as it not only has a beautiful color, but has a lighter taste. You can however use white onions if that's what you have on hand. I take the marination a step further and soak the onions first to remove the excess harsh flavor
- Lemon juice adds more acidity and freshness and also pickles the onions working in harmony with the sumac. Vinegar can be a substitute, but it will change the flavor profile slightly. Red wine vinegar is preferable
- Extra virgin olive oil binds everything together and adds a touch of richness and also softens the onions even more
- Fresh chopped parsley adds freshness to the flavor and color. I always recommend not to chop the parsley too finely as you will lose the taste. Chopped cilantro or mint are good substitutes
- If you like spicy food, feel free to add some red pepper flakes or aleppo pepper for a little kick!
