Za'atar
Za'atar is a Middle Eastern spice blend typically combining dried herbs (thyme, oregano, or marjoram), sumac, sesame seeds, and salt. It contributes polyphenols and minerals but is nutritionally modest in typical serving amounts.
Also known as: zaatar, za'tar, thyme sumac blend, levantine spice blend

Za'atar is a traditional spice blend originating from the Levantine region of the Middle East, particularly Syria, Lebanon, Palestine, and Jordan. The blend's composition varies by producer and region, but commonly includes dried thyme, oregano, or marjoram (sometimes in combination), sumac, and white or black sesame seeds, with salt added as a seasoning and mild preservative. It is used as a seasoning for flatbreads, dips, grilled vegetables, and proteins, and is frequently mixed with olive oil to form a paste.
Za'atar is primarily a flavoring ingredient with minimal caloric or macronutrient contribution per typical serving. A tablespoon (roughly 5 grams) contains negligible protein, fat, or carbohydrates. The blend's nutritional relevance lies in its polyphenolic compounds—particularly from sumac and thyme—which have antioxidant properties. Thyme contains thymol and carvacrol, volatile oils studied for antimicrobial activity in vitro. Sumac provides hydrolysable tannins and flavonoids. As a dried herb mixture, za'atar does not significantly alter digestion, though individual sensitivity to spices is possible.
Polyphenol Content
Sumac and thyme are sources of plant polyphenols, compounds with antioxidant activity documented in laboratory and animal studies. Human intake of za'atar in typical culinary amounts—a sprinkle on bread or a teaspoon in a dip—delivers polyphenols in quantities similar to a single serving of herbs and is unlikely to produce measurable systemic effects. The practical significance of these compounds in a mixed dish depends heavily on total polyphenol intake from all food sources.
Tolerance and Intake Guidance
Za'atar is generally well tolerated by most people. Individuals with sesame allergy should verify the product contains sesame before purchase. Those sensitive to thyme or other Lamiaceae herbs may experience oral or gastrointestinal irritation. Za'atar contains added salt and therefore variable sodium; commercial blends typically contain roughly 100–350 mg of sodium per tablespoon, though brands with higher salt levels can exceed this range. Those restricting sodium intake should check product labels. No special portion limits exist for the general population; typical culinary use (1–2 teaspoons per serving or meal) poses no toxicity risk.
Frequently Asked Questions
Is za'atar nutritious?
Za'atar is primarily a flavoring used in small amounts. It contains polyphenols from thyme and sumac, but typical culinary portions (1–2 teaspoons) deliver modest quantities. It is not a significant source of calories, protein, or vitamins and should not be relied upon as a primary source of nutritional benefit.
Does za'atar contain gluten?
Pure za'atar (dried herbs, sumac, sesame, salt) is naturally gluten-free. However, some commercial blends may be processed in facilities that also handle gluten-containing grains, or may contain additives. Check the label if you have celiac disease or gluten sensitivity.
Can people with a sesame allergy eat za'atar?
Many za'atar blends contain sesame seeds. Those with a sesame allergy should verify the ingredient list before purchasing. Sesame is a labeled major allergen in the United States under the FASTER Act and is similarly recognized in many other countries.
How much sodium is in za'atar?
Sodium content varies by brand depending on how much salt is added. Most commercial za'atar blends contain roughly 100–350 mg of sodium per tablespoon, though some higher-salt formulations may exceed this. Those on a sodium-restricted diet should check product labels and account for za'atar when tracking daily sodium intake.
