What is zaatar

Overview

Za'atar represents one of the most distinctive and ancient spice blends in Middle Eastern cuisine. The name itself comes from Arabic "zatar," referring to the wild thyme plant (Origanum syriacum) that forms the foundation of the blend. While the exact composition varies by region and family recipes, a traditional za'atar blend combines dried wild thyme, sumac berries, and toasted sesame seeds with salt. The spice blend has deep historical roots in Levantine cooking, with evidence of its use dating back thousands of years in the region spanning modern-day Syria, Lebanon, Palestine, and Jordan. The distinctive sourness comes from sumac, a red berry that has been used as a souring agent in Middle Eastern cooking for millennia, predating the widespread use of lemon and vinegar as acidic ingredients.

Composition and Regional Variations

The primary component of za'atar is wild thyme, which grows abundantly throughout the Middle East and Mediterranean regions. Traditional blends contain between 30-50% wild thyme by weight, giving the spice its herbaceous, slightly peppery foundation. Sumac, the red berry of the sumac plant (Rhus coriaria), comprises 30-50% of quality blends and provides the essential tangy, lemony flavor without requiring actual citrus juice. The sesame seeds, typically white or mixed white and black varieties, add nutritional density and a subtle nutty sweetness, constituting 10-20% of the blend. Sea salt rounds out the mixture, enhancing flavors and acting as a preservative. Regional variations exist throughout the Levant: Palestinian za'atar tends toward a higher sesame content, Syrian blends often emphasize sumac's tartness, and Lebanese versions may include oregano or additional dried herbs like marjoram. Some commercial blends incorporate pomegranate powder, dried chili pepper, or additional sumac for variations in flavor intensity and color.

Nutritional Profile and Health Benefits

Za'atar offers significant nutritional benefits beyond its culinary appeal. One tablespoon (approximately 7 grams) of traditional za'atar contains roughly 16 calories, 1 gram of protein, and minimal fat. The sesame seed component provides calcium (approximately 88 mg per tablespoon), important for bone health, and magnesium (approximately 24 mg per tablespoon), crucial for muscle and nerve function. The wild thyme in za'atar contains thymol, a naturally occurring monoterpene with antimicrobial and antioxidant properties. Sumac provides high concentrations of polyphenolic compounds, particularly gallic acid and tannic acid, which demonstrate antioxidant capacity comparable to green tea and significantly higher than black tea. Studies conducted at Jordan University of Science and Technology in 2011 found that sumac-based spice blends showed antioxidant activity 3-4 times higher than pomegranate juice. The blend also contains minimal sodium compared to many commercial seasonings, with approximately 140-160 mg per tablespoon depending on salt content, making it suitable for low-sodium diets.

Traditional and Modern Uses

The most iconic use of za'atar appears in man'oushe (also spelled manakish), a beloved Levantine flatbread where the spice blend, mixed with olive oil to form a paste, tops the dough before baking. Traditional Palestinian, Syrian, and Lebanese versions of man'oushe remain ubiquitous street foods, sold at dedicated bakeries and food carts throughout the region, with families often purchasing freshly baked versions for breakfast or afternoon snacks. Za'atar serves as a finishing spice for hummus, where it's drizzled with olive oil on top of the chickpea dip, creating both visual appeal and concentrated flavor in each bite. The spice blend works excellently as a dry rub for grilled meats, particularly chicken and lamb, where its herbaceous notes complement the savory richness of the proteins. Vegetables roasted with za'atar—including zucchini, eggplant, tomatoes, and squash—develop complex, slightly tangy flavors that enhance the natural sweetness of the vegetables. Za'atar also appears as a condiment for white cheeses popular in the Levant, sprinkled over labneh (strained yogurt) or feta cheese, and even incorporated into simple dips made with tahini or Greek yogurt. Contemporary chefs have begun incorporating za'atar into non-traditional dishes, including popcorn seasoning, salad dressings, roasted nuts, and even baked goods like crackers and bread.

Common Misconceptions

One widespread misconception is that za'atar contains cayenne pepper or significant heat elements. In reality, traditional za'atar is savory and tangy rather than spicy, with minimal to no heat. While some modern commercial blends may add chili powder for variety, authentic Levantine za'atar contains no peppers and suits heat-sensitive palates well. Another common misunderstanding is that sumac is related to poison sumac, causing concern about safety. Poison sumac (Toxicodendron vernix) is an entirely different plant from the culinary sumac (Rhus coriaria), which has no toxins and is widely consumed throughout the Middle East, North Africa, and increasingly in Western cuisine. The confusion arises from shared family classification, but culinary sumac is completely safe and widely used. A third misconception suggests that za'atar is exclusively Lebanese or Palestinian, when in fact it is deeply embedded in the broader Levantine tradition shared equally across Syria, Lebanon, Palestine, and Jordan, with each region maintaining slightly different preparation traditions and flavor emphases.

Sourcing and Storage

Quality za'atar has become increasingly available in Western markets through Middle Eastern specialty stores, natural foods markets, and online retailers. When purchasing, consumers should look for vibrant red coloring from the sumac and visible sesame seeds, indicating freshness and proper proportions. Whole sumac berries and wild thyme can be purchased separately and combined by home cooks seeking maximum freshness and customization. Za'atar stores best in airtight containers away from heat, light, and moisture, maintaining optimal flavor for 4-6 months at room temperature. The spice blend should be stored in a cool, dark cupboard rather than above stoves where heat exposure degrades the delicate herb flavors. Once opened, many cooks store za'atar in the refrigerator, where it maintains quality for up to one year, preventing rancidity of the sesame oils and preserving the volatile aromatic compounds in the wild thyme.
