Marjoram and oregano and oregano and marjoram.
Have you noticed that these two spicy herbs are inseparable when you go to cooks’ reference books?
The reason is that marjoram and oregano are generic names for two frequently interchanged (but different) herbs.
Both are small aromatic shrubs that grow to approximately 2 feet (.6 m). Both are essential ingredients in Mediterranean cuisine, particularly Italian and Provençal cooking.
One goes by the name wild marjoram or oregano; the other goes by the name sweet marjoram.
Obviously there is plenty of room for confusion.
But there are differences.
Let’s start with taste: sweet marjoram has a slightly milder flavor than oregano or wild marjoram. The taste of sweet marjoram is warm and delicate faintly like sage with a sweet aftertaste of mint or camphor. Sweet marjoram is more widely available than oregano and is usually just called marjoram.
Oregano is more pungent than marjoram both in flavor and aroma. It is peppery with a bite and has a lemon thyme after note. If you tasted or smelled sweet marjoram and oregano side by side, you would definitely say oregano is the stronger, more assertive of the two. Maybe that’s why they call oregano “wild” marjoram. It’s edgier.
Sweet marjoram is used to flavor carrots, cucumbers, green salads, cottage and cream cheese, omelets, soufflés, soups, fish, chicken, lamb, and veal. Sweet marjoram should be added towards the end of cooking to ensure that its flavor is not lost.
Oregano—the wild marjoram—is used to flavor spreads, dips, mushroom dishes, pasta sauces—like spaghetti sauce, meat sauces, red meats and roasts, and pizza. Oregano is the classical zippy taste of pizza. Fresh oregano is also added towards the end of cooking, but dried oregano is enhanced by cooking as it has time to fully develop and mellow.
Oregano says southern Italy. Marjoram says northern Italy and southern France.
Need more? Oregano is also a favorite in Mexican cookery. It’s a go-to flavoring for bean dishes, burrito and taco fillings, and salsa.
Now you see.

Serve Marjoram. Add marjoram to salads, cheeses, fish, beef, pork, sausages, tomatoes, cabbage-family vegetables, potato soup, or vinegars. Add in the last few minutes of cooking, just before serving to veal and liver, in meat and egg dishes, and in poultry stuffings. Rub marjoram into roasting meat. Add marjoram leaves in soups, to pizza, tomatoes, or on roast beef sandwiches. Add chopped marjoram leaves in melted butter to spinach just before serving. Use to make herb butter.

Serve Oregano. Use oregano leaves with salads, cheese, eggs, tomato dishes and sauces, marinated vegetables, roasted and stewed beef, poultry, game, beans, shellfish, soups, vinegars, or pastas. Add fresh oregano toward the end of cooking. Sprinkle on cooked vegetables. Add dried oregano at the beginning of cooking so that it can develop in the cooking process. Oregano is essential to southern Italian cooking. It is used in spaghetti sauce and sprinkled on pizza. The flavor of oregano varies from variety to variety.
