Pho, the iconic Vietnamese noodle soup, is more than just a meal; it’s an experience. It’s a symphony of flavors and textures, a comforting embrace on a chilly day, and a testament to the power of simple ingredients expertly combined. At the heart of this culinary masterpiece lies a carefully curated blend of herbs, each contributing its unique essence to the broth’s depth and the overall dish’s vibrancy. But what exactly are these aromatic wonders, and how do they elevate pho to its revered status? Let’s delve into the fragrant world of pho herbs and discover the secrets they hold.
The Broth’s Botanical Foundation
The foundation of any great pho is, of course, the broth. While bones (typically beef or chicken) and spices play a crucial role, certain herbs are integral to creating its characteristic warmth and complexity. These herbs are typically simmered along with the bones, infusing the broth with their subtle yet essential flavors.
Cinnamon’s Sweet Embrace
Cinnamon, often in the form of cinnamon sticks or cassia bark, contributes a sweet and slightly spicy note to the broth. It’s not overpowering, but rather adds a gentle warmth that complements the savory flavors. The type of cinnamon used can vary, with some cooks preferring the more intense flavor of cassia. Its inclusion showcases the delicate balance pho achieves between savory and sweet elements.
Star Anise: A Licorice Kiss
Star anise, with its distinctive star shape and potent aroma, is another key player in the pho broth. It imparts a licorice-like flavor that is both complex and comforting. Too much star anise can overwhelm the dish, but the right amount adds depth and character. It’s a defining characteristic of the traditional pho flavor profile.
Coriander Seeds: A Subtle Citrus Note
Coriander seeds, often toasted to enhance their flavor, offer a subtle citrusy and slightly nutty note to the broth. They are less pungent than the fresh cilantro leaves that are used as a garnish, but they contribute a delicate aroma and complexity to the overall flavor profile.
Cloves: A Touch of Warm Spice
Cloves, used sparingly, provide a warm, spicy, and slightly sweet note to the broth. They can be quite potent, so just a few cloves are typically used to avoid overpowering the other flavors. Their addition adds a layer of depth and complexity to the overall aromatic profile.
The Fresh Herb Garnish: A Burst of Freshness
While the broth simmers with dried spices and herbs, the real magic often happens when the bowl is served, adorned with a generous heap of fresh herbs. These herbs provide a refreshing counterpoint to the rich broth and tender noodles, adding a burst of freshness and vibrancy to each bite. The selection of fresh herbs can vary depending on regional preferences and availability, but some are considered essential.
Thai Basil: A Sweet and Anise-Like Delight
Thai basil is perhaps the most recognizable and widely used fresh herb in pho. It has a distinct anise-like flavor with a hint of sweetness, which complements the savory broth and adds a refreshing touch. Its aromatic leaves are a welcome addition to any bowl of pho, enhancing the overall sensory experience.
Cilantro: A Zesty and Bright Counterpoint
Cilantro, also known as coriander leaves, is another staple herb in Vietnamese cuisine, and pho is no exception. It offers a bright, zesty flavor that cuts through the richness of the broth and adds a refreshing element. While some people find its flavor soapy, it is a beloved herb for many and a crucial component of the pho experience.
Mint: A Cooling and Refreshing Touch
Mint, typically spearmint or peppermint, provides a cooling and refreshing element to the pho. Its subtle sweetness and aromatic leaves complement the other herbs and add a layer of complexity to the overall flavor profile. It provides a welcome contrast to the savory and spicy notes of the broth.
Bean Sprouts: A Crunchy and Refreshing Texture
While technically not an herb, bean sprouts are often included as a fresh garnish alongside the herbs. They provide a crunchy texture and a slightly sweet, refreshing flavor that complements the other ingredients. They add a delightful textural contrast to the soft noodles and tender meat.
Lime: A Zesty Citrus Zinger
A wedge of lime is almost always served with pho, allowing diners to customize the acidity and brightness of their bowl. The lime juice adds a zesty, citrusy note that enhances the flavors of the herbs and broth, creating a more vibrant and refreshing experience.
Other Regional Variations and Lesser-Known Herbs
Beyond the core herbs mentioned above, some regional variations of pho may incorporate other herbs, such as:
-
Sawtooth Coriander (Ngo Gai): This herb has a stronger, more intense flavor than regular cilantro and is sometimes used in Southern Vietnam.
-
Rice Paddy Herb (Ngo Om): Also known as limnophila aromatica, this herb has a unique citrusy and cumin-like flavor. It is more common in Southern Vietnam.
-
Perilla (Tia To): Perilla has a distinct, slightly bitter flavor that is often used in Korean and Japanese cuisine as well. It is more common in Northern Vietnam.
These variations highlight the diversity and regional nuances of pho, showcasing the creative use of local ingredients.
The Art of Balance and Harmony
The beauty of pho lies not only in the individual ingredients but also in the way they are combined to create a harmonious and balanced flavor profile. The herbs work together to create a complex and aromatic experience that is both comforting and invigorating.
The Broth’s Fragrant Symphony
The herbs simmered in the broth provide a foundational layer of flavor, adding warmth, sweetness, and spice. They create a complex and aromatic base that is essential to the overall character of the pho.
The Fresh Herb Garnish: A Finishing Flourish
The fresh herb garnish provides a burst of freshness and brightness, complementing the rich broth and adding a vibrant touch. It’s the finishing flourish that elevates the pho from a simple soup to a culinary masterpiece.
Customization and Personal Preference
One of the great things about pho is that it can be easily customized to suit individual preferences. Diners can add more or less of the various herbs and garnishes to create their perfect bowl. This allows for a personalized and satisfying experience.
Understanding the Herb’s Role in Pho’s Health Benefits
Beyond the delightful taste, the herbs in pho also contribute to its nutritional value. Many of the herbs used are known for their antioxidant and anti-inflammatory properties.
Antioxidant Powerhouses
Herbs like cilantro and basil are rich in antioxidants, which help protect the body against damage from free radicals. Antioxidants contribute to overall health and well-being.
Anti-Inflammatory Properties
Some of the spices used in the broth, such as cinnamon and cloves, have anti-inflammatory properties that can help reduce inflammation in the body. This may contribute to improved joint health and reduced risk of chronic diseases.
Digestive Aid
Several of the herbs used in pho, such as mint and ginger (often used in the broth), can help aid digestion and relieve digestive discomfort.

The world of pho herbs is a fragrant adventure waiting to be explored, and the reward is a culinary experience that is both delicious and deeply satisfying. The interplay of these aromatic elements is what truly elevates pho to its iconic status.
What are the most common fresh herbs served alongside Pho?
The fresh herbs served with Pho are essential for adding brightness and complexity to the broth and noodles. Typically, you’ll find a generous plate of cilantro, Thai basil, mint, and sometimes scallions. These herbs are not merely garnishes; they are meant to be torn and added directly to the bowl to release their aromatic oils and enhance the overall flavor profile.
Cilantro contributes a fresh, slightly citrusy flavor, while Thai basil offers a distinctive anise-like sweetness. Mint provides a cool, refreshing element, and scallions add a mild oniony bite. Each herb complements the rich broth and savory meat, allowing you to customize your Pho to your personal preference. Experimenting with different combinations is key to finding your perfect blend.
How does the herb selection differ between Northern and Southern Vietnamese Pho?
While the core ingredients of Pho remain relatively consistent across Vietnam, the herb selection often reflects regional variations. In Northern Vietnam, where Pho originated, the herb plate is typically simpler, focusing on cilantro and scallions, sometimes accompanied by a few sprigs of Thai basil or mint, if available. The emphasis is often placed on the quality of the broth and the freshness of the noodles and meat.
In Southern Vietnam, the herb plate tends to be more abundant and diverse, reflecting the region’s richer agricultural landscape. Besides the standard cilantro, Thai basil, and mint, you’re more likely to find saw tooth herb (ngo gai), bean sprouts, and sometimes even culantro (ngo om). This wider selection allows for greater customization and a more intensely aromatic experience.
What is “Rau Que” and how does it contribute to the flavor of Pho?
“Rau Que” is the Vietnamese name for Thai basil, a key herb used in Pho, particularly in Southern Vietnamese variations. Thai basil is easily identifiable by its purplish stems and slightly serrated leaves, which have a distinct anise or licorice-like aroma and flavor. It is often contrasted with Italian basil, which has a sweeter, less pungent taste.
The addition of Thai basil to Pho provides a unique aromatic and flavor dimension that elevates the dish beyond its core ingredients. Its slightly spicy and sweet notes complement the rich, savory broth and add a layer of complexity that many Pho enthusiasts consider indispensable. Tearing the leaves before adding them releases more of their essential oils, maximizing their impact.
What is “Ngo Gai” (Saw Tooth Herb) and what does it taste like?
“Ngo Gai,” also known as saw tooth herb or thorny coriander, is a fragrant herb frequently included in the herb plate accompanying Southern Vietnamese Pho. Its leaves are long and narrow with serrated edges, resembling the blade of a saw, hence the name. It offers a stronger, more pungent flavor compared to cilantro, with a slightly resinous and peppery undertone.
The unique flavor profile of ngo gai adds depth and complexity to the Pho broth. While some may find its taste overwhelming, its inclusion is deliberate and contributes to the overall aromatic tapestry of the dish. It is best used sparingly, as a little goes a long way in enhancing the savory and herbaceous notes.
Are there any herbs added directly to the Pho broth during cooking?
While the fresh herbs are usually served alongside Pho to be added by the diner, certain dried spices and herbs are crucial for flavoring the broth during the long simmering process. These aromatics typically include cinnamon sticks, star anise, cloves, coriander seeds, and sometimes black cardamom. The combination of these spices creates the signature fragrant base of Pho broth.
The specific ratios and combinations of these spices are closely guarded secrets passed down through generations of Pho chefs. The long, slow simmering allows the spices to release their oils and infuse the broth with their complex flavors, resulting in a rich, aromatic, and deeply satisfying base for the dish. These spices provide warmth and depth, contrasting beautifully with the freshness of the herbs added later.
Can I use dried herbs as a substitute for fresh herbs in Pho?
While dried herbs can be used as a substitute in a pinch, they cannot fully replicate the vibrant flavors and aromas of fresh herbs. Dried herbs lack the volatile oils that give fresh herbs their distinctive character, resulting in a less intense and less nuanced flavor profile. The texture also differs significantly, with dried herbs often becoming somewhat brittle or woody.
If you must use dried herbs, it’s best to rehydrate them slightly before adding them to the bowl. However, for the best possible Pho experience, it is highly recommended to use fresh herbs whenever possible. The difference in flavor and aroma is significant and well worth the effort of sourcing fresh ingredients.
Why is the freshness of the herbs so important in Pho?
The freshness of the herbs served with Pho is paramount because it directly impacts the flavor and overall sensory experience of the dish. Fresh herbs contain higher concentrations of volatile oils, which are responsible for their distinctive aromas and flavors. These oils degrade over time, causing the herbs to lose their potency and vibrancy.
When fresh herbs are torn or chopped and added to the hot broth, the heat releases these volatile oils, creating a burst of aroma and flavor that complements the savory richness of the soup. Using wilted or stale herbs will result in a muted and less appealing flavor profile, detracting from the overall enjoyment of the Pho.
