What it is

A robust culinary herb commonly used fresh or dried.

Plain-language buying tip

Check whether the label identifies a specific oregano type when you want a particular regional flavor profile.

Forms and use

Use dried oregano early in sauces, braises, and marinades; add fresh oregano more sparingly toward the end.

Common forms include fresh leaves, dried leaves. Match the form to the job: dried oregano added early to sauces, braises, and marinades, fresh oregano added more sparingly toward the end.

Storage

  • Dried leaf: one to two years, which makes it one of the better-keeping dried herbs. Rubbed between the palms it should still be sharply aromatic, not dusty.
  • Dried on the stem (bunches): holds longer than loose crumbled leaf and is how a lot of good oregano is sold. Strip what you need.
  • Ground: six months to a year. Rarely worth buying — oregano's leaf is small enough to crumble with your fingers, and the ground version fades much faster.
  • Container and place: sealed and out of the light. Green herbs bleach to grey-brown on a sunny shelf, and that fade tracks flavour loss closely enough to judge by.
  • Gone when: crushing a pinch in your palm releases almost nothing, or the smell is hay-like with no pepper behind it. Colour helps: live dried oregano is grey-green, spent oregano is brown.

Quick questions

What should I check before buying Oregano?

Check the stated botanical identity or style when available, the form, and the ingredient list. These details are more useful than relying on a broad category name alone.

Substitutions
  • Mexican oregano is a different plant: Mediterranean oregano is Origanum vulgare, in the mint family; Mexican oregano is usually Lippia origanoides — long sold and written up as Lippia graveolens, which Kew's Plants of the World Online now treats as a synonym of L. origanoides; the family is the same either way, Verbenaceae, the verbena family. Mexican oregano is also sold as Lippia palmeri and Poliomintha longiflora, which is why "usually" is doing real work in that sentence. Mexican oregano is more citrus and faintly resinous; Mediterranean is minty-peppery. They are not interchangeable — Mexican oregano in a tomato-and-basil sauce tastes out of place, and Mediterranean oregano in a pot of chili or a pozole tastes thin.
  • Marjoram: the closest relative and a good swap in the mild direction. Use about 1 1/4 times as much marjoram for oregano, and add it later in the cooking since it is more delicate.
  • Thyme: a workable stand-in in roasts, beans and braises at the same quantity. Woodier, less peppery.
  • Fresh for dried: oregano is one of the few herbs that is arguably better dried, because the pungency concentrates. The usual 3:1 fresh-to-dried ratio holds reasonably well here — 1 tbsp fresh for 1 tsp dried.
  • Za'atar or Italian seasoning for oregano: both contain it, both contain other things. Fine if the rest of the blend fits the dish.
Pairings
  • Ingredients: tomato, olive oil, garlic, onion, lemon, red wine vinegar, feta and other salty cheeses, olives, capers, cucumber, aubergine, courgette, potato, white beans, chickpeas, lentils, rice, lamb, chicken, pork, sardines and other oily fish, black pepper, chili flakes, cumin, paprika, bay, thyme, marjoram, parsley.
  • Dishes: a long tomato sauce, Greek salad, roast lamb or chicken with lemon and oregano, a white bean stew, chili and bean pots (Mexican oregano), pozole and posole, salsa, pizza, marinades for grilled meat, a vinaigrette for warm potatoes.
  • Go carefully: oregano is pungent enough to bully a dish. In a delicate fish or a light vegetable soup, use half what you think. It also benefits from being added early in wet cooking, unlike most dried herbs — it needs liquid and time to open up.
