Updated 05-10-14. 1x1.trans The History and Evolution of Pho: A Hundred Years JourneyAmong all the Vietnamese dishes that came to the attention of the people in the western hemisphere, nothing else has received such tremendous acceptance as pho. Pho is considered as the national dish of Vietnam, and it has captured the fascination of so many people in the west because of its deceptive simplicity and its complex flavors. Pho is the perfect comfort food – warm, hearty and deliciously refreshing. In Vietnam it’s the common people’s food. It’s street food.

Pho can also be seen as a mirror that reflects Vietnamese heritage and way of life. A dish that is steeped in tradition, pho is closely tied to Vietnam that the history of pho can read as a parallel to the history of its country of origin itself in the last hundred years. With the migration of Vietnamese across the globe after the Fall of Saigon in 1975, the national dish of Vietnam came to grace the tables of people of different heritages, thus leading to the colorful evolution of pho throughout the years. In this article I’ll discuss pho, its history and what makes pho many people’s favorite dish.

What Is Pho?

Of course, before I go into the history of pho, we should first tackle a more fundamental question about pho, namely: What in the world is pho?

Many readers know exactly what pho is. Articles on pho that you find around the Internet define the dish simply as Vietnamese noodle soup, traditionally made with beef or chicken broth that is flavored with various spices and topped with various herbs. But this definition seems far too simplistic because it does not really capture the rich and intense essence of beef in the broth that can only be achieved by simmering marrow-rich beef bones on low heat for at least three hours. It does not describe the complex layers of flavor created by the herbs and spices in pho. It does not illustrate the many textures created by the chewy rice noodles, the tender beef slices and the crunchy bean sprouts in the soup.

At the very least, the description “noodle soup” may be a misnomer. Soup implies that the dish is a side dish, but in fact pho itself is the main course. Pho is a noodle dish, and not a soup dish. So if you catch the phrase “noodle soup” somewhere on this side then it’s only because I let my guard down for a moment there. Pho should be called “Vietnamese noodle” or “soup noodle” because it is a noodle dish.

You cannot expect two bowls of pho made in two separate kitchens to ever taste the same. There are many recipes of pho existing out there, with each recipe somewhat different from each other. But those are only the published ones. There are countless others that are closely held by professional chefs running popular pho restaurants, and we’ll never know what they are. So techniques in cooking and preparing pho vary from chef to chef. Variations can also depend on what type of pho is being prepared. For instance, pho bac, which is pho from the northern regions of Vietnam, is made quite differently from how pho is prepared in southern Vietnam.

The history of pho stretches only a hundred years back in Vietnam’s recent past. But just as those hundred years have shaped Vietnam into the country it is today, so do those hundred years have shaped the way pho has become. Three events in Vietnamese history have marked the history of pho. They are

  1. The unification of Vietnam under French rule in 1887,
  2. The splitting of the country into North and South Vietnam in 1954, and
  3. The Fall of Saigon in 1975.

Here’s an article on “What is Vietnamese Pho: Think You Know? Think Again,” which discusses what is and what is not pho.

The Murky Beginnings of Pho: a French Connection?

Despite the fact that pho is a reflection of the culture and history of Vietnam, no one really knows how pho came to be. Restaurateur and author Mai Pham’s research on pho, as cited in Vietnamese culinary expert Andrea Nguyen’s blog, stated that there is nothing written about the early history of pho. All there is left are oral traditions handed down by elders. It is, however, agreed upon by many experts in Vietnamese cuisine, including Ms. Pham and Ms. Nguyen, that the history of pho began in Hanoi in northern Vietnam and that it started when the French colonized the country in the late 1880s.

In the SpiceLines interview on Ms. Nguyen, she said that before the French conquered Vietnam, the Vietnamese people did not slaughter cows for food. Instead, they used these animals to till their rice fields and as beasts of burden.

The general theory held by most Vietnamese culinary experts is that the word “pho” is a corruption of the French “feu” or “fire.” Pho could be a Vietnamese adaptation of the French soup “pot au feu” or French beef stew, which the French brought to Vietnam when they came to rule the country. But let me take this theory further into something more concrete to possibly reflect facts. It is this: Vietnamese love to take foreign words and use them as our own, but with a Vietnamese accent. Thus “feu” became “Phở.” But there’s more. It’s always been a popular knowledge that the French, specifically a man named Jesuit Alexandre de Rhodes in the country between 1624 and 1644, helped convert Vietnamese written language from a variant of Chinese characters into the modern age with translations using the Latin alphabet system. So the French connection to pho and Vietnamese language is much more intimate than casual, and it’s not unthinkable that pho did come from feu. Read more on the Vietnamese alphabet.

“Pot au feu” literally means “pot on the fire,” signifying the long hours required to create the soup. Just like with pho, cartilaginous, marrow-rich beef bones are used to make the broth of the pot au feu. These bones are left to boil and simmer in water on low heat for at least three hours, and the scum and foam formed by excess grease from the bone marrow are skimmed and discarded.

Another similarity that pot au feu shares with pho is the fact that ginger and onions are also roasted in an open flame before they are added to flavor the broth. Vegetables like carrots and turnips are used to top pot au feu. In pho, these vegetables are replaced by bean sprouts and herbs, with a little lime juice added in for taste.

Pho Bac: Pho of the North

Another theory that Vietnamese cuisine experts agree on is that the birthplace of pho is northern Vietnam, near Hanoi. Given the theory that pho is a Vietnamese adaptation of the French pot au feu, it is not surprising to think that pho originated from the north.

Hanoi has always been the center of political power in colonial Vietnam, with only a few short interruptions. The city has always been the seat of Vietnamese kings and emperors since 1010, except during the rule of the Nguyen dynasty, when the capital was moved to Hue. When the French conquered Vietnam and established the colony they called the French Indochina, they made Hanoi their capital city.

The French brought pot au feu to Vietnam and introduced the idea of slaughtering cows for food to the Vietnamese of the north. The northern regions of Vietnam are not as rich as those in the south, and food scarcity is not a stranger to a northern Vietnamese household. The northern Vietnamese get their food where they can find it, and they learned to take the beef parts and bones that their French conquerors did not want for their table. It is widely believed that this is how pho of the north, called pho bac, came to be.

Pho bac has an intense and delicate flavor that is entirely different from pho nam, which is pho of the south. The focus of pho bac is on the taste of its clear and simple broth. The star anise and other spices commonly used in pho serve as subtle undertones of flavor rather than complex layers. The main ingredients in pho bac are the rice noodles and the thinly sliced rare beef cooked quickly in the hot broth. You would not find a bowl of pho bac topped with the popular herbs and garnishing found in pho nam or in pho outside of Vietnam.

Even today, northern Vietnamese and pho purists consider pho bac the true pho. It is not uncommon to find a person from northern Vietnam or a pho purist to turn away from lavish preparations of pho nam or from pho that is not made from beef stock. Some of them find such preparations shocking and even disgusting.

Pho Nam: Pho of the South

French rule did not last in Vietnam. The Second World War saw the country known as French Indochina fall under Japanese occupation, although the new Japanese rulers retained their French administrators. But France was not to regain her full political influence on Vietnam. After the war, a series of events led to the splitting of Vietnam into North Vietnam and South Vietnam in 1954. North Vietnam, which is Communist country, kept Hanoi as its capital. South Vietnam is a democracy centered on Saigon (or Sài Gòn).

Thousands of North Vietnamese fled the Communist rule, and escaped across the border to South Vietnam. These refugee families took with them their cherished pho recipes and introduced pho to their brethren in the south. Here, pho is to make a turn that eventually shocked pho purists from the north.

Unlike in North Vietnam, food is rich and abundant in South Vietnam. Herbs and other ingredients are used liberally. The Vietnamese of the south put their taste for the lavish on the frugal pho bac to create the classic pho nam. They put more spices in their pho than their northern counterparts. They experimented with other beef parts, and even used other ingredients such as chicken and tripe. They added bean sprouts and herb garnishing as topping on the soup. They were also very liberal about the use of fish sauce and hoisin sauce to flavor their pho.

Pho flourished, and due to its versatility and popularity, Vietnamese eat pho everyday, at any time during the day. Pho vendors do business everywhere, from pushcarts to neighborhood street stalls, from pho restaurants to elegant bistros. But most importantly, pho is the food of the working people.

The Fall of Saigon and the Evolution of Pho

Conflicts between North and South Vietnam continued long after 1954. These conflicts were fueled by the Communist superpowers, namely the Soviet Union and Communist China, who gave their support to Communist North. Into the fray also came the Americans, who favored the Democratic South Vietnam. The conflicts became known as the Vietnam War, which raged full scale from 1963 to 1973, and ended in the Fall of Saigon in 1975.

The Fall of Saigon saw masses of Vietnamese people flee for their lives to various corners of the world. Many of them were accepted to the United States in the few years immediately after 1975, while many others tried to escape in rickety boats as “boat people” for 15 or more years to come. These Vietnamese boat people created colonies in neighboring countries such as Malaysia, Indonesia and the Philippines, although some even reached as far as Australia and even Europe.

Among the treasures that Vietnamese refugees brought with them from their homeland were their cherished pho recipes. South Vietnamese (including Northern Vietnamese who fled to the South in 1954) were by far the majority of the refugees and what they brought with them was the Southern style pho. Before long, restaurants serving pho emerged in the communities these Vietnamese migrants established in their country of exile, and these restaurants introduced pho to their non-Vietnamese neighbors.

As time went on, an evolution of pho was seen outside of Vietnam. Although the basic ingredients were retained, pho recipes were adapted to suit whatever ingredients were available locally. Non-Vietnamese who attempted to create their own version of pho also used techniques and ingredients that are far away from the traditional methods of creating pho.

One cannot stop evolution. Personally, I admire the creativity of these chefs, but if you want good pho, then go where the crowd eats. Chances are they eat the more authentic kind.

Vietnamese Pho Today

Outside of Vietnam many Vietnamese culinary experts have taken upon themselves to protect pho and help it retain its traditional identity. Pho has nonetheless taken on an adaptive nature. Many other versions of pho have emerged outside of Vietnam that contain seafood and pork and are called “pho” by their creators. Such dishes actually already exist in Vietnamese cuisine, being called “hu tieu” with different local variations.

For the pho connoisseurs, these so-called seafood or pork pho recipes cannot be considered pho in the strict traditional sense. In any case, the fact remains that pho has captured the fascination of people from all over the world because of the appeal of its distinct and layered flavors. There’s no question you’ll find great tasting and authentic pho in many of Vietnam’s local pho shops. But wherever you are in the world – whether in the United States, in Europe, in Australia or even in other Asian countries – you are sure to find a Vietnamese restaurant that serves pho as well, the authentic kind.

Hello Cuong Huynh,

Thank you for an informative article on Pho. I am making a documentary on Pho and would love to have an interview with you. Please let me know if you’ll be interested.

Thank you.

Wow! I’m very fascinated by this article. I find it truly informative. It explains the background of “PHO’ to a whole new level. I too would also like to post this in my restaurant for everyone to see. Please tell me your thoughts.

Is “Pho” not the name of the used noodles in this food-style…..

The original “Pho” noodles are different like other rice noodles, right.

9 Cuong August 30, 2012 at 4:06 pm

Hi Jens: Pho is the name of this soup noodle dish, and also the name of the noodle style as well. In fact the complete name of the rice noodle itself is “bánh phở” which you can read more about in this article Banh Pho (Bánh Phở) – It’s All About the Square Noodles.

Interesting ariticle and facts.
If I am not mistaken by Vietnamese history, the majority of the Northern immigrants that escape South due to the Vietnamese nationalists’ persecutions as being traitors were among the well to do population.
Beef is something that only well to do people can afford at the time. Why do you think that the French is the only one who wanted to slaughter cows for food, when cows are the “work horse” so to speak for majority of the population then. Hanoi populations are the polititians, the traders, and the ruling class. Hence, they used to eat Pho as a treat at the time. When the Northerns came south bound and had to start again from scratch, Pho was re-created to firstly appease the sense of home for these people and secondly a way to make a living. Take a look at Saigon now or before it became Uncle Ho’s city, and you will understand why. Pho has always been a type of food that only well to do or upper class people in vietnam can afford. The cost of a bowl of Pho before 1975 can easily equated to lunch and dinner for a typical family in Vietnam as the time. Entrepreneur is always a great trademark for all Vietnamese here in the states or at home in Vietnam.

The Southerners are not that crazy over Pho now or ever, because it is not within the range of theirs taste buds. Nevertheless, there are a few that would have a try at Pho. “Common People Food” is a relative term, depend on how you look at it. Common to the Northerners in the south would be more fitting. The differences between North and South Pho stock preparation are most likely due to the Entrepreneurism.

11 Cuong November 2, 2012 at 10:06 pm

Thanks for your input and comments Johnny. Northerners had pho, and the Southerners had hủ tiếu. That is, until they brought it to the South, then there were more choices for the South, but Northerners (and therefore pho itself) came to Saigon mostly. As a result, Southerners outside of Saigon did not get much exposure to pho itself. And you are right, many Southerners do not prefer pho over hu tieu, they prefer their hu tieu. I love hu tieu myself. It is a beautiful dish; there’s something beautiful about such simple soup noodle in look and preparation (which use pork and/or seafoods.) If we Viet don’t have pho, I would eat either hu tieu or the more spicy Bun Bo Hue any day.

With respect to the rich and the well-to-dos and the educated who emigrated to the South with pho, I would say that beef would not have been a staple food ingredients in Vietnam anyway before Western influence came into the country (I will have to check this fact so please do not hold me to this 100%, but I’ll go ahead and make this point now). Having money is one thing, but tradition would not have beef as part of a Viet’s daily diet. Of course for the well-to-do, beef, venison, snake or any other “exotic” meats can be had for a price and they can afford them. That’s why they are called the affluence. But one thing for sure, the Viet affluence can definitely afford Western/French influence such as western culinary (and beef as an ingredient,) ballroom dancing, music, western clothing, and many other “foreign” things brought into the country just because by definition, the affluence and the educated had a business to know, to learn and to enjoy such things.

With respect to “common people food,” I would say that one can find a version of pho in Saigon, then and now, that will fit any budget. And by “common” here I meant “poor” or “working people,” not “mass popular” although sometime the two can be the same ;) In any case I do not disagree with you, just offering my own take in response to your excellent and thoughtful comments.

And don’t start me on what you call “Entrepreneurism.” I love and admire a good entrepreneur (because I am one) but in my opinion, some just go too far and mess up a good thing like pho.

I surfed to your site while looking up pho origins. I’m looking forward to reading all the amazing content. I appreciate the summary you gave of what Viet American chefs think to be true and I want to offer a different geneaology for pho. Please check it out:

And if you ever want to cruise down to San Diego and try authentic thit tai, let me know and I will email you the names of the parishes that sell it.

13 Cuong May 15, 2013 at 7:07 pm

@Ly-Huong: Thanks for sharing the interesting article. The topic of pho in Vietnam and in America is a very complex one, with multitudes of viewpoints offered my many experts, so-called or real. I think we’ll have many theories for continued discussion for a long time to come, and I do not think we’ll have a resolution any time soon. The most important thing, for me anyway, is to not knowingly or unknowingly misinform, and to make sure what we do and say is honest and sincere based on our own knowledge and experience. That’s the respect that pho deserves and it’s a goal of It’s hard enough to deal with the many facets of pho, it’s even tougher to correct thing that are not quite correct especially on the Internet.

I wish I have enough fundings and time to do a complete research on the subject matter. The way I see it, like many other things in this world, the longer we let pho go undocumented, the higher risk that we will lose what we had. We as a people have this amazing national dish, yet we do not attempt to document it, protect it, nurture it, and promote it the way it should be.

On another note, I do live in San Diego, so thanks for the tip about the parishes. But what is the point of “authentic thit tai”, and why are parishes selling “authentic thit tai”? In the context of pho, thit tai is whatever lean beef (at various quality levels and cuts that one cares to pay for) that you prepare raw to be enjoyed in beef pho. That’s all it is, right? Am I missing something? Please do explain.

14 Van June 4, 2013 at 12:34 pm

I was wondering if these were real facts. I’m not saying that they’re lies, but I want to use this article as one of my sources for a research paper and don’t want to be penalized for having invalid statements.

15 Cuong June 4, 2013 at 12:49 pm

Hi Van: Thanks for considering this article as a source of your research. As in any good research work, you should always practice due diligence in your independent research and fact checking.

This is a subject matter that is dear to my heart, and clearly historical documentation is very much lacking. A complete research must include visits to Nam Dinh in North Vietnam, and that has not happened yet. I have myself spent many hours in my own research, but I will admit that there are many more questions and clarifications that I’d still like to pursue, personal resources permitting.

16 latiesha August 19, 2013 at 6:41 pm

what is your national food in Vietnam???

17 Cuong August 20, 2013 at 12:08 pm

@latiesha: It is difficult to specify and for everyone to agree on a national food for a country. I guess one definition might be a dish that is popular within a country and also well-known outside of that country. And it obviously must include the unique way it is prepared and served, the indigenous ingredients that it contains, or the tradition that it represents, or all of the above. For Vietnam, pho would be one as it is unique to our country, but then there are numerous other dishes that are also unique and popular in Vietnam as well.

18 sebcolin May 10, 2014 at 12:37 pm

your article is very interesting but there are so many mistakes about history of this vietnamese soup.
1)Alexandre de Rhodes hasnt As a teacher at Inalco (history of Asia) in Paris, i would like to tell you that the pho has nothing to do with ” le pot au feu”.Pho has nothing to do with fire (feu). Pho means rice noodles in vietnamese! If you read vietnamese novels and poems, you can find traces of this pho from the 14th century before Alexandre de Rhodes and missionnaires came to Vietnam.
Since then it has evoluted. And the more sophisticated is the pho you find in the south. The northern pho is very simple and you eat only in the north. The southerners add different herbs and sauce that brings to this soup so many tastes. The southern pho is the one that you can eat all around the world today!

19 Cuong May 10, 2014 at 1:28 pm

@sebcolin: Thanks for leaving your comments. I wouldn’t characterize the article to have “so many mistakes” as you described. I’ll address or clarify the points as follows.

Your first point is not quite clear about Alexandre de Rhodes and the word feu. Did you try to link the 2? If so then maybe you have misread the point. Alexandre de Rhodes was mentioned because he was the major influence to initiate the conversion of the Viet language from Chinese-like characters to Latin script, or Vietnamese alphabet. He had not much to do with feu or pho.

With respect to feu, I don’t think I indicated anywhere that pho is fire, or pho has something to do with fire. But then most cooking do use fire. And especially when it comes to pot of feu and pho, they are both simmered over fire for a long time. So the connection/similarity clearly exists.

The point is the word “pho” may be an adaptation, a corruption, or an alteration of “feu” with traditional Vietnamese accent given to it. It’s pretty much like “xe tăng” for the battle field vehicle called the tank, or “nhà băng” for the place where people keeps their money called the bank. These are just a few of the numerous examples of western words being adapted by Viet people to conveniently describe things that don’t exist in Vietnam at the time they were introduced. I don’t doubt we Viet may have had rice noodle banh pho going way back before Alexandre de Rhodes, and I’d love to read the novels and poems you’ve mentioned if you can provide sources. I would postulate that they may have been a distant cousin of “hủ tiếu” due to Chinese influence; instead of using Chinese egg noodles, we used rice noodle in our hủ tiếu.

To recap, the connection points being made are as follows: we had rice noodle (maybe for a long time), and we may already have had something like hu tieu, then a Frenchman converted Chinese-like characters to Viet alphabet, then the French brought over pot au feu, which we may have liked the way it’s made with beef, then we created pho or modified hu tieu to make something called phở. The theory is, without those events mentioned, we may not have pho today.

On your point of southern pho being around the world today, I do strongly agree. Obviously, after the fall of Saigon in 1975, the people who left Vietnam were mostly from the South (including Northern Vietnamese who fled to the South in 1954.) And what they brought with them was the Southern style of pho. I will clarify this point in the article. Thank you for your input.
