Instructions

1. 1 Gather all ingredients.
2. 2 Make broth: Place beef bones in a 9-quart (or larger) pot; season with 1 teaspoon salt. Pour water into the pot and bring to a boil. Reduce heat and simmer broth for about 2 hours.
3. 3 Meanwhile, set an oven rack about 6 inches from the heat source and preheat the oven's broiler. Line a 10x15-inch roasting pan with aluminum foil.
4. 4 Place onions and unpeeled ginger onto the prepared roasting pan and cook under the preheated broiler, stirring occasionally, until vegetables are charred, 10 to 15 minutes.
5. 5 Cool slightly. Chop onions, then peel and slice ginger; set aside separately.
6. 6 Skim fat from surface of simmering broth. Add oxtail, radish, and charred onions to broth. Tie charred ginger, anise, cinnamon stick, peppercorns, and cloves in cheesecloth to make a bouquet garni; add to broth. Stir in sugar, fish sauce, and remaining 2 teaspoons salt. Simmer over medium-low heat for at least 4 hours (the longer, the better). Season with salt.
7. 7 Strain broth. Discard bones and bouquet garni. Reserve meat from bones for another use. Chill broth in the refrigerator, 8 hours to overnight.
8. 8 Skim and discard fat from the top of chilled broth. Pour broth into a pot; bring to a boil. Reduce heat and keep hot until ready to serve.
9. 9 Bring a pot of water to a boil. Turn off heat. Stir in rice noodles and let sit until noodles are tender yet chewy, 6 to 10 minutes.
10. 10 Meanwhile, cut frozen sirloin into paper-thin slices.
11. 11 Drain and divide noodles among bowls, about 1 1/2 cups per serving. Top each with a few sirloin slices. Ladle hot broth over sirloin and noodles.
12. 12 Serve and enjoy!
