Cilantro Vs Parsley: What's The Difference?

What is cilantro?

Cilantro is the fresh leaves and stems of the Coriandrum sativum plant, an annual herb in the Apiaceae (parsley) family. The herb has a distinctive bright, citrusy, herbaceous flavor that's prominent in Mexican, Latin American, Thai, Vietnamese, Indian, and Middle Eastern cuisines. About 4-14 percent of people have a genetic variation that makes cilantro taste soapy or metallic; this is real and not just a preference. Cilantro leaves are dark green, small, and have distinctly rounded scalloped edges. The stems are slender and tender, also edible with similar flavor. Cilantro should be added at the end of cooking to preserve flavor; long heat exposure destroys the volatile compounds. The fresh herb wilts quickly; store wrapped in paper towels in a plastic bag for best refrigerator life.

What is parsley?

Parsley is a fresh herb in the Apiaceae family, related to cilantro botanically but with very different flavor. The two main varieties are flat-leaf parsley (also called Italian parsley) and curly-leaf parsley. Flat-leaf is preferred for cooking due to more robust flavor and easier chopping. Parsley has a clean, slightly peppery, grassy flavor without the citrus notes of cilantro. The herb is used extensively in European, Mediterranean, and Middle Eastern cuisines: as a garnish, in tabbouleh (where it's the main ingredient), in pesto-style sauces (gremolata, salsa verde), and as a finishing herb on countless dishes. Parsley is rich in vitamin K, vitamin C, and iron. Like cilantro, it should be added at the end of cooking to preserve flavor and color.

How do you tell cilantro and parsley apart?

Smell test is most reliable: rub a leaf between your fingers and sniff. Cilantro has a distinctive citrus-soap aroma; parsley has a clean grassy smell. Visual differences are subtle but real: flat-leaf parsley leaves are more pointed and have more deeply serrated edges; cilantro leaves are rounder with shallower scalloped edges. The colors differ slightly: cilantro is a slightly lighter, brighter green; parsley is a darker, more saturated green. Stems differ: cilantro stems are slender and tender; parsley stems are firmer and more fibrous. Taste a small leaf if uncertain. At the grocery store, the herbs are often placed together, making confusion easy; both bunches are typically tied with twist ties or rubber bands with origin labels.

Can you substitute one for the other?

Not directly due to dramatically different flavors. For people who hate cilantro (the soap-tasting gene), parsley is the standard substitute in Mexican and Asian recipes; it provides freshness and color without the polarizing flavor, though the dish won't taste authentic. For people allergic to parsley (rare but real), cilantro is the closest visual substitute but adds different flavor. For garnish purposes, either works visually. For finishing herbs in salads, salsas, or rice dishes, the substitution depends on the cuisine: parsley fits European and Mediterranean better; cilantro fits Latin American, Asian, and Indian. Mint provides a different freshness in cilantro-based dishes when needed. Basil is another fresh herb substitute, though it has distinctly different flavor character.
