Pho vietnamese broth

Vietnamese pho broth: the heart of the national dish, made with charred bones, spices like star anise and cinnamon, and long simmering.

About this subject

Pho, Vietnam's iconic dish, revolves around its broth. This broth is made by simmering beef or chicken bones for hours, typically 8 to 12 hours, creating a collagen-rich, flavorful liquid. The bones are first char-grilled or roasted to release oils and aromas, then boiled with a set of spices: star anise, cloves, cinnamon, ginger, and coriander seeds. The technique of toasting spices before adding them to the broth is crucial to extract their aromatic profile. Onions and ginger are often charred over an open flame, adding a subtle smokiness.

There are two main regional variations: northern pho (Pho Bac) and southern pho (Pho Nam). In the north, the broth is clearer and slightly saltier, focusing on the pure bone flavor. In the south, the broth is darker and sweeter, with more sugar and fish sauce, and served with accompaniments like fresh herbs, bean sprouts, and lime. Hanoi is known for its pho tradition, where the broth is served in simple bowls with minimal garnishes to appreciate its complexity. Pho became popular in Vietnam in the early 20th century, influenced by Chinese and French immigrants, but the broth evolved into its own distinct style.

Making pho broth is considered a family art, often passed down through generations. The bone-to-water ratio, simmering time, and spice balance are closely guarded secrets. Chefs adjust the heat to maintain a gentle boil, preventing cloudiness. The broth is then seasoned with salt, fish sauce, and sometimes a little sugar. The result is a translucent, golden broth with layered flavors: umami from bones, sweetness from onion and ginger, and warmth from spices. In Vietnam, pho is primarily eaten for breakfast, but now enjoyed any time of day.
