Ingredients
- Broth:
- 3 lbs beef bones (shank or femur bones work well)
- 1 lb pork hocks, cut into 2-inch pieces
- 8 cups water
- 4 stalks lemongrass, bruised
- 2 large onions, charred
- 4-inch piece of ginger, charred
- 2 tablespoons salt
- 1 tablespoon sugar
- 1 tablespoon fish sauce
- 1 tablespoon shrimp paste (mam ruoc), optional but highly recommended for authentic flavor
- 1 tablespoon annatto oil (dau dieu), for color and flavor
- Spice Paste:
- 2 tablespoons chili flakes (adjust to your spice preference)
- 2 tablespoons paprika
- 4 cloves garlic, minced
- 2 shallots, minced
- 2 tablespoons vegetable oil
- Noodles and Toppings:
- 1 lb thick rice noodles (bun bo hue noodles)
- 1 lb thinly sliced cooked beef shank or brisket
- 1/2 lb Vietnamese pork sausage (cha lua), sliced
- 1/2 cup cooked cubes of pig’s blood (optional, but traditional)
- 1/2 cup sliced green onions
- 1/2 cup chopped cilantro
- 1/2 cup sliced banana blossom
- 1/2 cup bean sprouts
- Lime wedges, for serving
- Chili oil, for serving (optional)

Instructions
- Prepare the Broth: Rinse the beef bones and pork hocks thoroughly. In a large stockpot, combine the bones, hocks, and water. Bring to a boil, then reduce heat and simmer for at least 2 hours, skimming off any scum that rises to the surface. This is crucial for a clear broth.
- Char Aromatics: While the broth simmers, char the onions and ginger over an open flame or under a broiler until blackened. This adds a smoky depth to the broth. Peel off the outer layer of the charred onion and ginger before adding them to the broth.
- Add Aromatics and Seasonings: Add the charred onions, charred ginger, bruised lemongrass, salt, sugar, fish sauce, and shrimp paste (if using) to the simmering broth. Continue to simmer for another hour.
- Prepare the Spice Paste: In a small saucepan, heat the vegetable oil over medium heat. Add the minced garlic and shallots and sauté until fragrant, about 1-2 minutes. Add the chili flakes and paprika and cook for another minute, stirring constantly, until fragrant and the oil turns a deep red color. Be careful not to burn the spices.
- Add Annatto Oil and Spice Paste to Broth: Stir in the annatto oil and spice paste into the broth. Simmer for another 30 minutes to allow the flavors to meld. Adjust seasoning to taste.
- Prepare the Noodles and Toppings: While the broth is simmering, cook the rice noodles according to package directions. Drain and rinse with cold water to prevent sticking. Prepare all the toppings: slice the cooked beef, pork sausage, green onions, cilantro, banana blossom, and bean sprouts.
- Assemble the Bun Bo Hue: In a large bowl, place a portion of cooked rice noodles. Top with slices of beef, pork sausage, and pig’s blood (if using). Ladle the hot broth over the noodles and toppings. Garnish with green onions, cilantro, banana blossom, and bean sprouts. Serve immediately with lime wedges and chili oil (optional).
Tips for Success
- Don’t Skip the Charring: Charring the onions and ginger is essential for developing the smoky flavor characteristic of Bun Bo Hue.
- Simmer, Simmer, Simmer: The longer the broth simmers, the more flavorful it will become. Don’t rush the process!
- Adjust the Spice: Start with a small amount of chili flakes and add more to taste. Remember, you can always add more spice, but you can’t take it away.
- Use Fresh Ingredients: Fresh herbs and vegetables will significantly enhance the flavor of your Bun Bo Hue.
- Taste and Adjust: Taste the broth frequently and adjust the seasoning as needed. You may need to add more salt, sugar, or fish sauce to achieve the desired flavor balance.
- Don’t be Afraid to Experiment: Bun Bo Hue is a versatile dish, so feel free to experiment with different toppings and seasonings to create your own unique version.
