In a medium saucepan, toast cinnamon sticks, star anise, and cloves over medium heat until fragrant. Add bone broth in the pan, followed by ginger, soy sauce and fish sauce. Bring to a boil and simmer for 10 minutes to allow the spices to fully infuse the broth.
Take the beef out of your freezer and slice it into thin strips. Divide the beef into two portions and add on top of the zoodles in the serving bowls.
Once the broth is done, also divide it into two portions and pour the hot broth into the serving bowls. The beef will start cooking instantly and the color changes.
Top the pho with bean sprouts, fresh herbs, sliced pepper and green onion, drizzle with Sriracha or/and hoisin sauce, squeeze some lime juice in it and slurp up!
