Instructions

  1. Step 1: Rinse 2 lbs beef bones and place in a large pot with 12 cups water. Bring to a boil over high heat and skim off any scum for 10 minutes. Drain bones and rinse pot.
  2. Step 2: Return bones to the pot with 12 cups fresh water, add 3 bruised lemongrass stalks and 2-inch sliced ginger. Bring to a simmer over medium heat and cook uncovered for 3 hours, skimming occasionally.
  3. Step 3: After simmering, remove bones, lemongrass, and ginger with a slotted spoon. Stir in 1 tbsp dried chili flakes, 1/4 cup fish sauce, and 1 tbsp rock sugar. Adjust seasoning to taste.
  4. Step 4: Meanwhile, soak 8 oz rice vermicelli noodles in warm water for 15 minutes until pliable, then drain.
  5. Step 5: To serve, divide noodles between 4 bowls. Top with 8 oz thinly sliced beef sirloin. Ladle hot broth over the beef to cook it gently.
  6. Step 6: Garnish with 1 cup bean sprouts, 1/2 cup fresh Thai basil, 2 tbsp sliced green onions, sliced red chili, and lime wedges for squeezing. Enjoy the spicy, aromatic flavors of Huế.
