In a medium pot, combine the beef bone broth, sliced fresh ginger, star anise, and cinnamon, bringing the mixture to a boil before simmering for 10 minutes.
While the broth infuses, soak the dry rice noodles in a bowl of hot water for 5 to 8 minutes until they are tender and pliable, then drain.
Slice the raw eye of round steak against the grain into paper-thin strips to ensure they cook quickly when the broth is added.
Remove the ginger and star anise from the broth using a slotted spoon, then stir in the fish sauce, sea salt, and black pepper.
Place the softened rice noodles into a large serving bowl and arrange the thin beef slices in a single layer on top of the noodles.
Pour the boiling hot broth directly over the beef, allowing the heat to flash-cook the meat until it turns slightly pink and tender.
Garnish the bowl with fresh bean sprouts, cilantro, Thai basil, and jalapeño slices, finishing with a squeeze of fresh lime juice.
