- 1 pound beef brisket
- 12 cup beef stock
- fish sauce, to taste
- 1 (16-ounce) package dried wide rice noodles, cooked according to package directions
- 12 ounce beef top round, thinly sliced
- 1 bunch green onions, trimmed, thinly sliced, about 1 cup
- garnishes: thai basil sprigs, mung bean sprouts, lime wedges, jalapenos thinly sliced into rings, sriracha sauce, hoisin sauce
- Step 1: Place 1 pound brisket in a large pot; add 12 cups beef stock.
- Step 2: Heat to a boil over high heat; lower to a vigorous simmer. Simmer until cooked through, 30-45 minutes.
- Step 3: To check doneness, remove the brisket from pot; poke with a chopstick. Juices should run clear.
- Step 4: A few minutes before the brisket is ready, prepare an ice water bath. When brisket is done, remove from pot; submerge in ice water. Reserve cooking liquid.
- Step 5: When brisket is cool, remove from ice water. Pat dry; thinly slice against the grain. Set aside.
- Step 6: Return stock to a boil. Season with fish sauce, if needed.
- Step 7: Divide cooked rice noodles evenly among large warmed soup bowls. Divide brisket slices among the bowls, then add the raw slices of beef top round (they will cook slightly when stirred into the broth).
- Step 8: Ladle boiling hot stock over top. Top with green onions; serve immediately with garnishes.
