Updated 06-03-17. There are three main elements to every bowl of Vietnamese pho: the steamy, flavorful and aromatic broth; the meat, whether it is tenderly cooked chicken or beef that is rare or well-done; and the banh pho noodle. It's the banh pho that makes pho a noodle dish. Without banh pho noodle, it's just another soup. Many Vietnamese culinary experts will tell you that the life of pho is in the broth because that is where most of the flavors that characterize this dish are in. But one can argue that the body of pho is in the banh pho noodle itself. Everything else - the fresh herbs, the bean sprouts, the sliced Serrano chili (or jalapeno in the U.S.,) the lime wedges and all the other fixings in the bowl - is just optional, nice to have stuff.
What is Banh Pho Noodle?
Let's start with a quick definition. Banh pho is the noodle used in pho dish. What differentiates banh pho from other noodle varieties is banh pho has square or rectangular cross-sections (depending on width size), as opposed to mostly round cross-sections most other noodles come in. For the purpose of this discussion, I'll use banh pho and banh pho noodle interchangeably. Banh pho are noodles made from rice flour. In countries other than Vietnam, they are called chantaboon or rice sticks. Modern conveniences have seen banh pho sold as dry packaged varieties in supermarkets and grocery stores, but the ideal banh phoare those made fresh. These Vietnamese noodles are flat and white, with widths varying from a millimeter to a centimeter, or even wider (or 1/16" to wider widths of 1/8", 1/4" or sometimes even 3/8".) When banh pho is cooked, its texture becomes soft and chewy, and its appearance translucent.
Banh Pho: An Essential Pho Ingredient
Why is banh pho so important in a bowl of pho? One can say that pho is not pho without the correct banh pho rice noodles in it. You can eliminate the garnishing, but you cannot take banh pho noodles out of a proper bowl of pho. And you can't have just few strands of banh pho floating in the broth, you have to have a whole lot of them. In fact in a restaurant, it's totally an acceptable option to order more banh pho in your bowl than normally served (see the article on "Tips on Ordering Pho Your Way.") Here's another way of looking at it. In Vietnam and Southeast Asia in general, a meal is always composed of a main dish that is starchy and made of carbohydrates. These come in the form of either steamed rice or noodles. The other dishes made from meat, seafood or vegetables eaten at the table during the meal are just side dishes that complement the rice or the noodles served. There may be a soup side dish served along side the other side dishes. This is called "canh" in Vietnamese, and is often consumed in small bowl sized portion over rice or by itself during the course of the meal.
Banh Pho: The Foundation of a Pho Meal
A meal in Southeast Asia is never complete without the rice or the noodles, and when pho, hu tieu or any other noodle dish is the meal, the noodles are the foundation of such meal. Vietnamese pho is a complete meal in a bowl. The broth serves as the soup, the rice noodles the starchy element, the meat as the protein, and the herb garnishing and the bean sprouts as the salad part. All these elements form a unified whole and the meal would not be filling (nor fulfilling) without the rice noodles. However, it is not enough that the rice noodles just exist in the bowl. In an Asian meal, the rice dish is so important that its quality dictates the tone of the entire meal. If one has to force down rice that was not properly cooked, it spoils the meal even if the side dishes were made for the kings and emperors. The same thing applies to banh pho noodle. Bad noodles make bad pho. Banh phoshould be fresh, with a slippery texture that is smooth enough for a good and easy slurp. If they are of the dried, supermarket variety, they should be prepared carefully. They should not sit in sticky clumps in the bottom of the bowl, and they should not be tough to chew on. Neither should they be so overcooked that they break apart when you pick them up with your chopsticks.

How Banh Pho Is Made
As mentioned above, banh pho noodles are made from rice flour. Although the dried version is now available in supermarkets and grocery stores, these noodles are best when they are freshly made. In Vietnam, it would not be surprising to find a family that makes its own banh pho.
I've done some consulting with a banh pho factory in Vietnam, and the process is quite involved and takes real skills when done the old-school ways. Many factories nowadays use modern equipment to increase productivity, improve sanitary conditions, and maintain quality consistency with a lot less labor. Still Westerners may not approve of the sanitary conditions and standards at these "factories". Here's banh pho production the old-school/hand-made way with the help of more modern machinery. It's in Vietnamese but non-Viet speakers can still get the idea.

Preparing Banh Pho for Pho
Properly preparing banh pho noodles for serving in pho depends on whether you use the dry or fresh banh pho. If the banh pho is the dry type, then they should be soaked in hot water for 15 to 20 minutes, and drained afterwards. The resulting noodles should be soft and translucent.

But if the banh phois fresh, it should be rinsed under cold running water and then blanched in boiling water for no more than a few seconds, until the desired softness and translucence is achieved. The noodles are then placed in individual bowls, occupying about a third of the available space. Obviously those who like more noodles in their pho can add more banh pho as desired. Just remember to scale down on the other ingredients as the noodle will expand in the hot broth. The meat is placed over banh pho, and then the piping hot broth is ladled into the bowl.
The Bottom Line: Pho Is not Pho Without Banh Pho
Substituting a different noodle may be acceptable at home but what you have then is "broken" pho. No self-respecting pho restaurant will serve pho without properly prepared banh pho, because it's just "wrong." If you run across someone serving pho with round noodles (bun or vermicelli,) demand your money back because it is something else and certainly not pho they're selling you. Or if you as a customer request a different noodle yourself, then pat yourself on the back for being adventurous, but please come back and order to correct banh pho next time 😉
