Are Coriander and Cilantro the Same? Here’s What You Need to Understand

Coriander and cilantro often get mixed up since they both come from the same plant, Coriandrum sativum, which originates in Asia, Africa, and Europe. But that’s where the similarities end, as each herb has its distinct flavor and characteristics. What exactly sets them apart, and which dishes do they work best in? We’ll dive into these differences and more as we explore coriander vs. cilantro.

What Is Coriander?

In the United States, coriander is commonly understood to refer to the seeds of the Coriandrum sativum plant, which are used as a spice, especially when dried or ground,” says Amy Davis, RDN.

Although coriander is typically found ground in most grocery stores, some places also sell whole coriander seeds that you can add to your dishes or grind yourself with a mortar and pestle. Using whole seeds in cooking often intensifies the coriander flavor in your recipes.

What Is Cilantro?

On the other hand, many people wouldn’t realize cilantro comes from the same plant as coriander just by looking at it. “Cilantro refers to the green leaves and stems of the Coriandrum sativum plant, typically used as a fresh herb,” explains Davis.

However, when traveling internationally (or watching a non-American cooking show), you might often hear chefs call cilantro coriander, which can cause confusion, as each of these ingredients offers quite different flavors and uses.

The mix-up between coriander and cilantro arises because in many parts of the world, the entire plant is referred to as coriander. The leaves are called coriander leaves, while the dried spice is known as coriander seeds,” explains Davis.

Coriander vs. Cilantro: Understanding the Differences

Let’s explore more closely how the different parts of the Coriandrum sativum plant vary from one another.

Appearance

As Davis pointed out, coriander and cilantro differ significantly in appearance. In their whole form, coriander seeds resemble black peppercorns and have a light brown color. When ground, coriander takes on an even lighter, almost beige hue.

Cilantro, on the other hand, is a vibrant green herb with delicate, slender stems. These stems are so tender that they’re completely edible and often included in recipes using cilantro.

Smell

Coriander and cilantro also differ greatly in scent. “Cilantro has a fresh, citrusy aroma, whereas coriander seeds have a fragrant, nutty undertone,” says Davis. Some describe cilantro as having lemony, herbaceous, or even soapy notes, while coriander emits a spicy, warm, almost woody fragrance.

Flavor

The flavor is another key distinction between these two seasonings. “Cilantro provides a bright, fresh, and slightly peppery taste, while coriander brings a warm, citrusy, and mildly sweet flavor,” explains Davis. Cilantro’s flavor can be divisive, as people with the olfactory receptor gene OR6A2 are more likely to experience it as tasting like soap.

The flavor differences make each ingredient suited to distinct culinary uses. “Cilantro is typically used fresh for its bright, zesty flavor, while coriander seeds are incorporated as a warm spice,” says Davis.

Nutrition

Although they come from the same plant, coriander and cilantro differ quite a bit nutritionally.

“Coriander seeds are richer in fiber and various minerals, while cilantro contains higher amounts of vitamins A, C, and K,” explains Davis. Coriander also provides small quantities of calcium, phosphorus, and potassium, which, together with the fiber and plant compounds in the spice, support bone, immune, and heart health.

Meanwhile, cilantro is packed with plant compounds, B vitamins, vitamin E, manganese, and copper, all of which, alongside the aforementioned vitamins, contribute to improved metabolic, immune, eye, blood, and heart health.

Although coriander and cilantro are used as flavoring agents rather than main ingredients in dishes, you’re unlikely to get significant amounts of these nutrients from them. However, studies suggest both herbs provide neuroprotective, liver-protective, antimicrobial, antioxidant, and anti-inflammatory properties, which help prevent chronic illnesses like cancer, diabetes, and hypertension. These health benefits are likely tied to the phytonutrient (or plant compound) content of these ingredients.

How to Cook With Coriander

The good news is there’s no shortage of ways to incorporate these healthy ingredients into your cooking.

When cooking with coriander, this warm spice works best in slow-cooked dishes. “Coriander is ideal for adding warmth and complexity to cooked foods,” advises Davis.

This includes soups, stews, roasted vegetables, roasted meats (it pairs particularly well with chicken), curries, hummus, sauces, dips, and marinades. If you're using whole coriander seeds, make sure to either cook them down to release their flavor or grind them with a mortar and pestle before adding to your recipes, as leaving them whole may result in an unpleasantly crunchy texture.

How to Cook With Cilantro

Conversely, cilantro shines brightest in recipes where it’s kept raw for a fresh bite. “Cilantro works best in fresh, uncooked dishes, or as an herby topping,” Davis agrees.

This leafy herb is most commonly seen in Latin and Asian culinary classics, like salsa, guacamole, salad, chimichurri, crema, pho, stir fries, spring rolls, and noodle dishes where it’s often utilized as a raw ingredient or garnish. Though, it’s not uncommon to see cilantro cooked into certain recipes as well, including cilantro lime rice, roasted proteins, and even soups.

Can You Use Cilantro Instead of Coriander?

From these comparisons, you may have already come to the conclusion that although coriander and cilantro come from the same plant, they are really not interchangeable in the kitchen.

“Cilantro and coriander seeds should not be swapped for one another in cooking, as their flavors are distinctly different,” says Davis. However, there are some dishes where both ingredients can complement each other. For instance, coriander can be added to a rich, hearty stew and topped with cilantro for a burst of freshness. Another example is grilled chicken marinated in coriander, served with a vibrant cilantro-laden chimichurri, where both ingredients come together beautifully.

In the end, although these two flavorful ingredients can't replace one another in recipes, each brings its own unique qualities—both nutritionally and in cooking—that make them valuable additions to your kitchen arsenal.
