Instructions

1. 1Fry onions in oil until lightly browned. Remove and drain.
2. 2Rinse the beef bones, place in a stockpot, cover with cold water, and bring slowly to a boil . Reduce heat and simmer , uncovered, for 10–15 minutes. For a clear broth skim off foam.
3. 3After this initial cooking, add cooked onions, ginger, cinnamon, cardamom, star anise, cloves, garlic and peppercorns. Bring to a boil again and gently simmer the stock, partially covered, for a minimum of 6 hours but up to 12 hours if you can, skimming regularly. If necessary, add more water to keep the bones covered.
4. 4Strain stock to remove the vegetable and spices and discard them. Return the broth to the stove to keep it boiling hot.
5. 5In a large soup bowl, place a handful of cooked phở noodles, top with thinly sliced raw beef, and ladle on generous amounts of very hot broth, which will cook the raw beef. Garnish with sliced onions, scallions and coriander, and serve immediately.
