Oregano
or-EG-uh-noh
Origanum vulgare
Herbal, peppery, slightly bitter, aromatic.

What it is
Oregano is the dried or fresh leaf of Origanum vulgare, a hardy Mediterranean member of the mint family whose name comes from Greek for joy of the mountain. The flavor is herbal and peppery with a slightly bitter, aromatic warmth, and it is one of the rare herbs that tastes stronger dried than fresh. It is a defining note of Italian and Greek cooking, scattered on pizza, tomato sauces, and grilled lamb. Mexican oregano is a different plant with a more citrus, resinous edge, so the two are not always interchangeable despite the shared name.

What it pairs with
Goes wrong with: very delicate dishes that fresh herbs suit better.
Common in Italian, Mexican, Middle Eastern cooking.
Whole vs ground
Oregano is one of the few herbs that is often better dried than fresh, since drying concentrates its aroma. Use dried leaf for most cooking and reserve fresh for finishing. Ground oregano fades quickly, so whole dried leaf is the better buy.
How to handle it
Crumble dried oregano between your fingers as you add it to release the oils. Add it during cooking rather than at the very end, since a few minutes of heat brings out its warmth in sauces and rubs.
Storage
Dried leaf airtight and dark keeps its punch for about a year. Fresh oregano lasts a week wrapped in the fridge.
Buying note
Buy whole dried leaves rather than ground, and crush a little to check for a strong, warm aroma. Greek and Italian oregano differ in strength from Mexican oregano.
Classic dishes
pizza, Greek salad, chimichurri, tomato sauce.

|---|---|---|
| marjoram | use a little more | sweeter, milder, and more floral, less peppery |
| thyme | 1:1 | more savory and earthy, less of the pizza-herb note |
One odd thing
The name oregano comes from the Greek words for mountain and joy, a nod to the hillsides where the plant grows wild and perfumes the air.
