Marjoram: Flavor, Chemistry, Origins and How It Differs From Oregano

Marjoram is oregano’s sweeter, softer, more floral cousin, with none of oregano’s sharp bite, and it’s at home in sausages, potato dishes and roast meats. It’s the leaf of Origanum majorana, a small, bushy herb in the same genus as oregano, which also goes by “wild marjoram.” Even the often-repeated “joy of the mountain” actually belongs to oregano. Below: where it comes from, the compounds behind its smell, how it differs from oregano, and how to use and store it.

At a glance

What marjoram is

Origanum majorana is an annual or perennial of the temperate biome. Majorana hortensis is among its synonyms, a name you’ll still see on older labels and in older books. It’s a bushy herbaceous plant, typically 30–60 cm (1–2 feet) tall, and “sweet marjoram” is another name for it.

Marjoram and oregano

Both are Origanum species. Several aromatic herbs in the genus get called marjoram, and oregano (O. vulgare) also goes by wild marjoram. So “sweet marjoram” for O. majorana and “wild marjoram” for oregano is a real naming convention, not a mix-up.

In trade, they’re separate. The Codex standard for dried oregano covers every Origanum species except Origanum majorana.⁴ For a side-by-side look, see marjoram vs. oregano and our oregano profile.

Name

The Online Etymology Dictionary traces “marjoram” through Old French majorane to Medieval Latin maiorana. That word’s origin is uncertain, possibly Indian, and its form was influenced by Latin major, “greater.”⁵ The often-repeated “joy of the mountain” actually belongs to oregano: Britannica derives oregano from Greek oros, “mountain,” and ganos, “brightness” or “joy.”⁶

Flavor and aroma

Marjoram smells sweet, floral and slightly piney, with a mild warmth and none of oregano’s sharp bite. It’s also described as warm, aromatic, slightly sharp and bitterish. The University of Delaware’s extension service puts it among the medium-strength herbs, with basil, oregano and thyme.⁷

The compounds

Britannica puts the essential oil at about 2% of the plant, with terpinene and terpineol as the main components.² A 2022 review in the journal Life fills in the picture:³

• Two main chemotypes. Researchers sort marjoram into a terpinen-4-ol/cis-sabinene hydrate type and a carvacrol/thymol type, with exceptions like a pulegone-rich Brazilian sample.
• The sweet note. Cis-sabinene hydrate, with its acetate, is considered the compound responsible for sweet marjoram’s flavor.
• Wide ranges. Combined sabinene hydrates ran from 0.95% to 46.27% of the oil across the studies reviewed.
• Carvacrol types. Several samples in the review’s table, including ones from Greece and Türkiye, are carvacrol-rich, so some plants sold as marjoram are chemically close to oregano.
• Yield. Oil from the aerial parts ranged from 0.4 to 1.85 mL per 100 g of dry material.

The review puts the variation down to growth stage, climate, geography, soil salinity, storage and distillation method.³ Keep in mind these are essential oils from specific samples, not the dried marjoram in your jar.

Origin and history

Kew records marjoram as introduced in North Africa (Algeria, Egypt, Libya, Morocco and Tunisia), southern Europe from Spain to Greece, Great Britain, India and Venezuela, among other places.¹ The 2022 review notes cultivation in Morocco, Egypt, Tunisia and Algeria. You’ll often read that marjoram is indigenous to North Africa, but Kew lists it there only as introduced.

There are popular stories about ancient Egyptians using marjoram for healing and preserving, and Greeks weaving it into wreaths and garlands. We couldn’t trace a source for any of them, so we’ve left them out. Britannica does record an Origanum herb linked with happiness and Aphrodite, but that’s oregano, not marjoram.⁶

How marjoram is used

Marjoram’s smell and taste make it widely used in cooking, and it seasons many foods. It goes with:

• Roast and braised meats, especially pork, lamb and veal, and sausages
• Potatoes, beans, peas, mushrooms and egg dishes
• Tomato sauces, where it’s a softer alternative to oregano
• Herb blends such as herbes de Provence

Technique

Marjoram’s flavor lives in a volatile oil. The University of Delaware notes that long cooking costs herbs their flavor. It suggests adding them in the last 45 minutes of a long simmer, or adding part at the start and the rest later. Its starting amount for medium-strength herbs is 1 to 2 teaspoons for six servings.⁷ To swap forms, LSU AgCenter’s rule of thumb is one tablespoon of finely cut fresh herbs to one teaspoon of crumbled dried.⁸ For more, see marjoram uses and cooking with marjoram.

Buying and quality

We found no Codex or other international grading standard for dried marjoram, and the Codex oregano standard explicitly leaves it out.⁴ Good dried marjoram is gray-green, and its sweet smell comes up fast when you rub it.

Storage

No regulator or standards body we found publishes a shelf life for dried or fresh marjoram. The 2022 review lists storage among the things that change the oil’s makeup but doesn’t give a shelf life.³ Your nose is the practical test. To dry your own, see how to dry marjoram.

Nutrition

Dried marjoram weighs next to nothing: USDA gives 0.6 g per teaspoon and 1.7 g per tablespoon. Two tablespoons (3.4 g) supply about 2.8 mg of iron, roughly 16% of the FDA Daily Value of 18 mg, and about 68 mg of calcium, roughly 5% of the 1,300 mg Daily Value. We worked those out from USDA’s per-100 g values of 82.7 mg iron and 1,990 mg calcium. Vitamin C (51.4 mg per 100 g) comes to under 2 mg in that amount.⁹¹⁰ A teaspoon, which is more what you’d actually use, gives you about 0.5 mg of iron.

Safety

• Pyrrolizidine alkaloids. EU law caps these plant toxins at 1,000 µg/kg in dried marjoram, oregano, borage and lovage, and in mixtures made only of them, compared with 400 µg/kg for other dried herbs.¹¹
• Health claims. The NIH’s National Center for Complementary and Integrative Health has no fact sheet on marjoram.¹² You’ll see claims that marjoram tea aids digestion, lowers blood pressure, prevents atherosclerosis, protects against staph or colds, or works as a sedative or antidepressant. We couldn’t find a systematic review or health agency that backs any of them, and we don’t make those claims here.

Substitutes and comparisons

Oregano is the obvious swap, but it’s stronger and sharper, so start with less. Thyme works too in meat and bean dishes. See marjoram substitutes for a ranked list, plus:
