Za’atar and oregano are from the same plant family. In fact, the Za'atar herb is a variety of wild thyme. But this is where the similarity ends. The Za’atar herb actually lends its name to a mixture of different herbs and spices that create the final spice blend. These include toasted sesame seeds, dried sumac, salt, thyme, marjoram, and oregano,
It also tastes entirely different from oregano. Za'atar has a tangy, spicy, nutty flavor. Oregano has a fresher flavor with hints of grass and mint. They are also most commonly used in two different types of cuisine.
You’ll find Za’atar as a regular ingredient in Middle Eastern cuisine, while oregano is most famed for its place in Mediterranean dishes. You’ll also find oregano in dishes that hail from Greece and Mexico.
Just like oregano, Za’atar can be used in a variety of ways. It can be used on its own as a seasoning, added to yogurt to make a zingy-flavored dip, or mixed with lemon juice and olive oil to create a flavorful salad dressing.
