The plant typically has small, oval leaves with a deep green color and a strong, pungent, slightly bitter flavor, which intensifies when dried. Oregano is a dominant herb in Mediterranean and Italian cuisine, where it is valued for its pungent, slightly bitter flavor that complements a wide range of dishes, including sauces, meats, vegetables, and cheeses. Fresh oregano is often preferred for its more subtle taste, while dried oregano intensifies the herb's aromatic properties, making it a staple in spice blends like Italian seasoning.
