Ingredients

Instructions

  1. Step 1: Char 1 large halved onion and 3-inch halved ginger over an open flame or under a broiler until blackened, about 5 minutes, then rinse briefly in water.
  2. Step 2: In a large stockpot, add 2 lbs beef bones, charred onion, charred ginger, 4 star anise, 1 cinnamon stick, 5 cloves, 2 cardamom pods, 1 tbsp rock sugar, and 2 tsp salt. Fill with 5 quarts cold water and bring to a boil, then reduce to a simmer for at least 4 hours, skimming foam occasionally.
  3. Step 3: After simmering, strain the broth through a fine mesh sieve into a clean pot. Stir in 1/4 cup fish sauce and adjust seasoning as needed.
  4. Step 4: Meanwhile, soak 8 oz flat rice noodles in hot water for 15 minutes until softened, then drain.
  5. Step 5: To serve, divide noodles among 4 bowls. Top with 8 oz thinly sliced raw beef sirloin. Pour boiling broth over the beef and noodles to cook the beef instantly.
  6. Step 6: Garnish each bowl with 1 cup fresh bean sprouts, 1/2 cup Thai basil leaves, 1/4 cup chopped cilantro, and 3 sliced green onions. Serve with lime wedges and sliced chili on the side for customization.
