oregano leaves

Oregano (Origanum vulgare) is a perennial herbaceous plant native to the Mediterranean region, belonging to the mint family (Lamiaceae). The leaves are small, oval, and covered with fine hairs, ranging from green to grayish-green in color. Oregano possesses a warm, peppery, and slightly minty flavor profile with subtle camphoraceous notes, becoming more pronounced when dried. The most common culinary varieties include Greek oregano (Origanum heracleoticum), known for its robust flavor, and Italian oregano (Origanum majorana), which is milder and more delicate. Mexican oregano (Lippia graveolens), though botanically distinct, is frequently substituted and offers a citrusier, more assertive profile.

Oregano leaves are fundamental to Mediterranean, Mexican, and Middle Eastern cuisines. Fresh leaves are used in Greek salads, Italian pasta sauces, Spanish gazpacho, and Lebanese za'atar blends, while dried oregano is essential to Mexican mole, Italian pizza and tomato-based dishes, and Greek lamb preparations. The herb pairs particularly well with tomatoes, garlic, olive oil, and cheese. Oregano is typically added near the end of cooking when fresh to preserve delicate flavor notes, though dried oregano benefits from early addition to allow flavors to develop. It works equally well in marinades, dressings, and roasted vegetable preparations.
