A Guide to Vietnamese Herbs

By: Sivaraj Pragasm

One of the hallmarks of Vietnamese cuisine is the amount of condiments and other accompaniments you get with your dish. When you order a Vietnamese dish, and especially the country’s many noodle soups (phở, bún bò Huế, mì Quảng and bún riêu, just to name a few), your food usually comes with an entire basket-load of leaves and vegetables in different shades of green, and even purple.

These leaves are herbs that have been specially curated over generations to complement specific dishes for a variety of reasons, from enhancing the taste, to simply providing an additional source of fibre and nutrients.

So what exactly are these many herbaceous varieties, and why did the waiter place them next to your plate? Read on!

Vietnamese Perilla - Tía Tô

Probably the easiest herb to identify on this list. Vietnamese Perilla leaves are green on top, and purple underneath.

With a strong, earthy taste, these herbs usually come with popular soup dishes like phở and bún chả, along with salads and grilled meats.

Health benefits? Known for its antibacterial qualities, some households use the crushed leaves of Thai Basil to treat small cuts.

Culantro - Ngò Gai

It might sound like the title of a really bad sequel to a food-themed film, but culantro is an actual herb, with long, narrow, serrated leaves and a slightly stronger taste than cilantro... so maybe it is a sequel after all!

It’s usually served alongside hot pots and used for soups, only added if diners crave a bit of bitterness in the broth. In other words, it shouldn’t be eaten raw and directly from the stem.

Vietnamese Coriander - Rau Răm

Another popular herb, Vietnamese Coriander, is dark green and spotted with two purple streaks. It looks and smells like mint.
