What is parsley?

Parsley is an herb known for its mild, slightly peppery flavour that can enhance a wide range of dishes. Primarily, there are two types of parsley: curly leaf and flat leaf (also known as Italian parsley).

Curly parsley is often used as a garnish thanks to its vibrant, decorative appearance. Flat-leaf parsley, on the other hand, is preferred for cooking due to its stronger taste profile and versatility. Both are used as a sprig to salads or a sauce ingredient.

What is coriander?

Coriander is a staple in many global cuisines, like Indian, Mexican, and Thai. You've probably encountered it in salsas, curries, or as a garnish. Some folks avoid it because of its unique, somewhat soapy flavour, though.

Most people use its leaves and stems. However, you can also use the seeds as a spice since they have a warm, nutty taste.

Coriander vs parsley: What makes them unique from each other?

To compare these two herbs, we'll look at their flavours, uses, appearance, nutritional benefits, and other unique characteristics. Each herb brings something different to the table, and understanding these differences can help you make the right choice for your needs. So, regardless if you're whipping up a fresh salsa or a hearty stew, you'll know exactly which herb to reach for.

In terms of appearance

Curly parsley has tightly coiled, ruffled leaves and a bright green colour. The stems are thin and firm, making it look dense and bushy which is perfect for garnishing. Flat-leaf parsley, on the other hand, has broad and pointed leaves with a deep green hue. Their stems are sturdy and long, so they have a more open appearance compared to their curly counterpart.

Coriander has rounded lacy leaves with serrated edges. Its bright green colour and thin, tender stems give it a light and feathery look. They're also less dense in appearance. 

In terms of taste and flavour profile

Curly parsley has a mild, slightly peppery flavour with a hint of bitterness. It’s often used as a garnish rather than in cooking due to its milder taste. Italian or flat-leaf parsley, on the flip side, offers a more robust, peppery taste. This makes it a preferred choice for dishes like soups, stews, and sauces.

Coriander leaves are strong, pungent, and citrusy with a slightly spicy kick, which some people find soapy. It’s a staple in Asian, Latin American, and Middle Eastern cuisines. The seeds, however, are warm, nutty, and only slightly citrusy, and are used as a spice in various dishes.

Curly parsley is mostly used as food decor due to its appearance and mild flavour. It doesn’t overpower dishes and is great for finishing touches. Flat-leaf parsley, with its stronger profile, is sometimes used in other dishes as an ingredient.

Coriander’s uses in cooking are more varied. Fresh leaves are added to sauces, chutneys, and guacamole and as a garnish for soups and curries. Coriander seeds, either whole or ground, spice up stews, soups, and baked goods. 

In terms of nutritional value

Parsley and coriander, both members of the Apiaceae family, have impressive nutritional profiles. Here are some nutrients they both have:

• Vitamin K: For blood clotting and bone health

• Vitamin A: For vision and immune function

• Vitamin C: For the immune system and skin

They're also both rich in antioxidants, which help protect cells from damage and reduce inflammation.

The two also have nutrients unique to each. Parsley has good amounts of iron, which is important for blood production and the transport of oxygen around the body. It also contains folate that's good for the DNA.

Meanwhile, coriander has manganese, which is crucial for metabolism and bone formation. You can also get potassium from it to keep your heart and muscles healthy. 

In terms of shelf life

Fresh parsley lasts about 1 to 2 weeks in the fridge, while fresh coriander can last around 1 week. Both herbs can be frozen: chop them, put them in ice cube trays with some water or oil, and transfer them to a freezer bag.

You can also store them in the kitchen the same way. Dried parsley and coriander both last up to 1 to 3 years in an airtight container in a cool, dark place.

It's important to note, though, that dried parsley tends to lose potency over time, so use it within a year for the best results. Coriander seeds retain their flavour well, especially when you store them whole and grind them as needed. 

In terms of availability

Parsley is widely available year-round in most supermarkets and grocery stores. You can find it in both fresh and dried forms. It also grows easily at home, indoors in pots or outdoors in gardens, making it a popular choice for people growing an herb garden.

Coriander is also widely available, though fresh leaves may be more seasonal depending on the region. It's sold fresh, dried, and as seeds. Given its preference for cooler temperatures, understanding coriander growing conditions is key for home growers to avoid bolting (premature flowering). Here's a crash course:

• Plant coriander seeds 1/4 inch deep in well-drained soil.

• Keep the soil consistently moist, but not waterlogged.

• Coriander prefers cool temperatures around 60°F to 70°F (15°C to 21°C).

• It can tolerate a bit of shade but does best with at least 6 hours of sun per day.

If you're looking to cultivate your own herbs, bear in mind that coriander is an annual herb, so you'll need to replant it annually. On the other hand, parsley is a biennial and can be a more lasting addition. It's also wise to learn more about plant lifespans to plan your timings better.
