What's The Difference Between Oregano And Marjoram?

The difference between oregano and marjoram is all about the flavour and use in cooking. Here’s the breakdown to help you choose.

Quick Facts

  • Oregano and marjoram are related but have different flavours; oregano is bold and pungent, marjoram is sweet and floral, so can’t be used as substitutes for each other in recipes.

  • Both herbs have cultural and medicinal uses throughout history; oregano for its antimicrobial properties and marjoram for its calming effects and culinary uses.

  • Growing conditions for oregano and marjoram are slightly different; oregano does well in sandy well drained soil with no maintenance, marjoram in sunny spots and regular pruning to keep compact.

Oregano and Marjoram

Oregano and marjoram are like cousins in the plant world, both in the Lamiaceae family. Their botanical name Origanum comes from the Greek word origanon meaning ‘brightness’ or ‘joy of the mountains’. They look similar and have similar uses but are different herbs with different characteristics.

True marjoram, also called ‘knotted’ or ‘sweet marjoram’ is not to be confused with oregano which is sometimes sold under the same name. Oregano plants, including Greek oregano and Mexican oregano are generally more robust and have a stronger flavour than the milder and sweeter marjoram. This difference is important in the culinary world as each herb brings a different essence to the dish.

Flavours of Oregano and Marjoram

The flavours of oregano and marjoram are as different as night and day so can’t be used as substitutes for each other in recipes. Oregano is bold and pungent and can dominate a dish while marjoram is gentle, sweet and floral and enhances without overpowering. Understanding these flavours will help you use these herbs effectively in your cooking.

Oregano’s Bold Flavour

Oregano leaves are punchy with their strong and pungent flavour especially when grown in warm sunny conditions. This aromatic herb like Italian oregano is a staple in Italian cuisine, found in tomato based dishes, pasta sauces and grilled meats. Greek oregano has a unique licorice like flavour and a peppery aroma that can elevate the simplest of dishes and add a spicy flavour to the mix.

Oregano’s bold flavour makes it perfect for hearty dishes that can take its intensity. But that same strength can be overpowering in lighter recipes so use sparingly in those cases. Whether you’re sprinkling fresh oregano on a pizza or adding dried oregano to a stew, its flavour will linger.

Marjoram’s Sweet and Mellow Taste

Marjoram is seen as a milder and sweeter alternative to Origanum vulgare (oregano). Scientifically known as Origanum majorana, sweet marjoram has a floral scent and a woody flavour that adds a gentle touch to dishes. Its sweetness shines in salad dressings, herbal teas and lighter fare like fish and poultry.

Marjoram can be used as a substitute for oregano but will noticeably change a dish as marjoram’s light sweet flavour may not be as prominent in recipes that require oregano’s boldness. But if you want a gentle aromatic boost marjoram is a great choice that goes well with basil and thyme.


The history of oregano and marjoram is steeped in cultural and medicinal uses. These herbs were highly prized in ancient Greece and Rome not just for their culinary uses but also for their symbolism and health benefits.

Oregano was believed to bring happiness and banish sadness, a notion that was deeply ingrained in ancient cultures.

Ancient Uses of Oregano

In ancient Greece oregano was more than just a herb; it was a medicine. It was used internally and externally to treat skin irritations, infections and even snake bites. Oregano tea mixed with wine was a common treatment for poisoning and convulsions, showing its versatility and potency.

The ancient Greeks and Romans used oregano leaves as an antiseptic, utilising its natural antibacterial properties. This multifaceted use of oregano shows its importance in ancient medicine and its lasting legacy as a healing herb.

Marjoram Through the Ages

Marjoram’s history is just as interesting, with a strong focus on its symbolism and culinary uses. Ancient Greeks and Romans saw marjoram as a symbol of happiness and used it in wedding ceremonies and other celebrations. This association with joy and festivity is reflected in its name from the Greek word ‘origanon’.

Marjoram is native to the Mediterranean and Middle East and has been used for centuries in culinary and medicinal ways. Its sweet woody flavour was a staple in many traditional dishes and its calming properties were used in herbal remedies and teas.

Plant Details

Oregano and marjoram may be related but their plant characteristics are different. Oregano is a bushy perennial that can grow up to 2 feet tall forming robust aromatic mounds that attract bees with their tiny flowers.

In late summer oregano produces tiny flowers that can be white, pink or purple in small spikes, panicles or corymbs. These flowers add beauty to the plant and attract pollinators making oregano a great addition to any garden.

Marjoram Plant Description

Cooking with Oregano

Cooking with Marjoram

Fresh marjoram with its delicate flavour should be used fresh to retain its sweetness. Here’s how to use marjoram in your cooking:

Growing Conditions and Tips
