Unraveling the Subtle Differences Between Oregano and Marjoram

Marigold and oregano are two herbs that people often think are the same thing. At first glance, it’s easy to see why: they look a lot alike, grow in similar conditions, and both have a strong, earthy taste. But there are some important differences between these two kitchen tools that you should know about if you want to use them correctly when cooking. We’ll talk about the differences between oregano and marjoram in this article so you can use these herbs safely in your recipes.

How Are Oregano and Marjoram Alike?

Let’s first look at the characteristics that oregano and marjoram share

• They belong to the same genus Origanum and are part of the mint family Lamiaceae, This gives them a close botanical relationship

• Both oregano and marjoram are perennial herbs that can be grown successfully indoors or outdoors.

• They have similar growing requirements, thriving in well-draining soil and full sun.

• The herbs feature small green leaves, albeit marjoram’s are slightly hairier and lighter in color.

• If allowed to flower, they both produce pink/purple blooms.

• Oregano and marjoram carry notes of earthiness and woodiness in their flavor profile.

So in many respects, marjoram and oregano are nearly indistinguishable relatives. But looks can be deceiving…keep reading to uncover the key differences.

Appearance: Leaves, Stems and Flowers

While their similarities are plentiful, a few distinguishing physical characteristics set marjoram and oregano apart:

• Marjoram leaves are oval-shaped, smaller and more delicate. They are grayish green and slightly hairy.

• Oregano leaves tend to be oval, but wider and more rounded. They are a vibrant green and not as furry as marjoram.

• Marjoram stems are tender, not woody, and stand upright when the plant is mature.

• Oregano stems are woodier and sturdier than marjoram. The plants grow in a bushy mound.

• Marjoram flowers are small and white, blooming in subtle clusters at stem tips.

• The flowers of oregano can be white, pink, or purple. The flowers are larger and bolder.

Taste: Sweet vs. Earthy

When it comes to flavor, marjoram and oregano diverge into clearly distinct tasting profiles:

• Marjoram is sweet, subtle, and mildly citrusy. It has hints of pine and cloves. Overall, it is more delicate and reserved in flavor.

• Oregano packs a bold, earthy punch. It can be quite peppery, with undertones of mint and lemon. The flavor is robust and pronounced.

Dried oregano is particularly potent, taking on an almost medicinal taste. For marjoram, the dried form isn’t quite as popular since the subtle flavors dissipate more rapidly.

Usage: Dishes They Compliment

Due to their varying strengths of flavor, marjoram and oregano each shine in different dishes:

• Marjoram goes well with delicate foods like chicken, seafood, vegetables, bread, and cheese. It’s often used in salad dressings and goes well with fruits.

• You can put oregano with bold foods like red meat, tomato sauce, lamb, beans, olive oil, and eggs. It is famously used in pizza, pasta and Mediterranean cuisine.

Marjoram’s gently sweet side also lends itself nicely to desserts. It can provide a lovely flavor in custards, fruit compotes, scones and more. Oregano, on the other hand, is used almost exclusively in savory applications.

Nutrition: Oregano Wins

When evaluating the nutritional makeup of marjoram vs. oregano, oregano emerges as the healthier choice:

• It contains more than double the antioxidants as marjoram.

• Oregano has higher levels of vitamins A and K.

• It provides more fiber and a greater array of minerals.

• Two unique flavonoids in oregano, galangin and queretin, amp up its antioxidant power even further.

So while both herbs certainly provide nutritional value, oregano packs a more concentrated phytonutrient punch.

Origins: Mediterranean Cousins

The origins of oregano and marjoram can help explain their subtle differences:

• Oregano hails from the sunny, rugged climes of Greece and Italy. It became entrenched in Mediterranean cooking.

• Marjoram also originated in the Mediterranean. As it spread through Europe, it gained popularity in French and English cuisine.

These geographical and cultural origins influenced how each herb was ultimately used in regional dishes throughout Europe and the Mediterranean.

Can They Be Substituted?

In a pinch, oregano and marjoram can stand in for each other. However, a couple tips make for a smoother substitution:

• Since oregano is more pungent, use less of it. Start with 1/3 of the marjoram measurement and adjust to taste.

• Oregano stems are tough and woody. Remove them instead of adding the whole sprig like you would with marjoram.

And always remember that the flavor will turn out differently than if you used the intended herb. That bit of improvisation is part of the fun of cooking!
