Understanding Fatty Broth Pho (Nước Béo)
Fatty broth pho, known in Vietnamese as nước béo, is not a separate dish but a flavorful enhancement added to traditional pho. While many appreciate a crystal-clear pho broth as a sign of careful preparation, connoisseurs understand that the rendered fat is where a significant amount of the flavor resides. Skimming the fat is a common practice in many restaurants to achieve that clear, golden appearance, but reserving this 'liquid gold' is the key to creating a more decadent and beef-forward bowl of soup. Nước béo is essentially the reserved beef fat and concentrated essence that separates from the broth during the long simmering process.
The Role of Fat in Pho Flavor
Fat acts as a flavor carrier in food. Many of the aromatic compounds from the spices, like star anise, cloves, and cinnamon, are fat-soluble. This means that the layer of fat on the broth's surface holds a concentration of the pho's most complex flavors. When you add nước béo back into your bowl, you are reintroducing these concentrated flavor molecules, resulting in a more profound and satisfying taste. Beyond flavor, the fat contributes to the mouthfeel, giving the soup a luxurious, silky texture that coats the tongue and leaves a lasting impression.
Characteristics of a Delicious Fatty Broth
- Appearance: A good fatty broth has a glossy, shimmering surface from the rendered fat. It may not be crystal clear, but the slight cloudiness is a direct result of the flavorful solids and fat, which is desirable for those seeking a richer experience.
- Aroma: The aroma is deeply beefy and fragrant, with the warm, savory notes of the spices becoming more pronounced.
- Mouthfeel: It is rich and unctuous, providing a fuller, more substantial sensation compared to a lean broth.
- Flavor: The taste is a more intense, beefier version of the standard pho broth, with a heightened sense of savory depth.
How to Get Fatty Broth at a Restaurant
If you're at an authentic Vietnamese restaurant, getting fatty broth is a simple hack known by pho aficionados. Instead of scooping it off, restaurants often reserve the fat and can serve it on the side, sometimes with green onions added for extra sweetness.
To order nước béo at a restaurant, you can:
- Simply ask for a side of “fatty broth”.
- Use the Vietnamese term and request a side of nước béo (pronounced “nook-bayo”).
- For an even richer and more traditional experience, you can ask for a side of hành chần, which is blanched scallions prepared specifically to be eaten with the fatty broth.

Making Your Own Fatty Broth at Home
Creating a flavorful fatty pho broth is a process of patience. It involves a long, slow simmer to extract maximum flavor and fat from the bones.
- Roast the bones and aromatics: Begin by charring beef bones, marrow bones, and oxtails in the oven. Roast the onions and ginger as well. This caramelizes the ingredients, adding depth of flavor.
- Parboil the bones: After roasting, parboil the bones to remove impurities and create a cleaner broth base. Drain and rinse the bones thoroughly.
- Simmer with care: Combine the roasted and blanched bones with water and the charred aromatics. Add toasted spices like star anise, cinnamon, and cloves in a cheesecloth bag. Bring to a boil, then reduce to a gentle simmer for at least 5-6 hours. Maintain a very low simmer to prevent the broth from becoming cloudy.
- Reserve the fat: As the broth simmers, a layer of fat will rise to the surface. Rather than skimming it all off, you can reserve some of this flavorful oil. A classic method is to let the broth cool completely, and the fat will congeal on top, making it easy to separate.
- Assemble and serve: When assembling your bowl, ladle a scoop of the reserved fatty broth into your bowl of finished pho to enrich it to your desired level.
Conclusion
Far from being a sign of a poorly made soup, fatty broth pho is a secret weapon for achieving maximum flavor and richness. Known as nước béo, this concentrated fat and flavor essence allows for a customizable dining experience. Whether ordering a side of it at a restaurant or mastering the long simmer at home to reserve your own, embracing the fat is the connoisseur's way to enjoy a truly next-level bowl of pho.
