Equipment
- Instant Pot
Ingredients
Broth
- 3-4 pieces oxtail preferably grass-fed
- .5-2 lbs beef roast or brisket preferably grass-fed
- 2-3 quarts water don't exceed max fill line
- 5 pods star anise
- 3 whole cloves
- 1 cinnamon stick
- 2 black cardamom pods
- 1 tbsp coriander seeds
- 1 tbsp fennel seeds
- 1 onion (halved)
- 1 4 inch piece ginger sliced
- 3-4 cloves garlic for extra immune boosting power
- 1 tbsp sea salt plus more to taste
- 5 tbsp fish sauce more or less to taste
- 3 tbsp cane sugar or other sugar, to taste
For Serving
- 1 lb rice noodles
- bean sprouts
- green onions sliced
- pickled red onions or thinly sliced red onions
- fresh cilantro
- Thai basil
- mint leaves
- lime wedges
- hoisin sauce
- sriracha sauce
Instructions
- Parboil for clarity: Bring a large pot of water to a boil. Add oxtail and beef and boil 2–5 minutes until scum rises. Remove, rinse meat and bones under cool water; discard the cloudy water.
- Sear aromatics: Set Instant Pot to Sauté. When it reads HOT, place onion halves and ginger cut-side down. Sear ~1 minute until lightly charred.
- Toast spices: Add star anise, garlic, cloves, cinnamon, black cardamom, coriander, and fennel. Toast ~30 seconds until fragrant.
- Add water & meat: Pour in 2–3 quarts water (stay under max line). Add the rinsed oxtail and beef. Stir in 1 tbsp sea salt.
- Pressure cook: Seal. Cook on High Pressure for 4 hours for a rich broth (or 2 hours for a lighter broth). Natural or quick release is fine.
- Season: Add fish sauce (start with 3–5 tbsp) and 3 tbsp sugar. Taste and adjust salt/fish sauce.
- Cook noodles: Prepare rice noodles per package; drain.
- Assemble bowls: Divide noodles into bowls. Ladle over hot broth with pieces of meat. Top with sprouts, green onions, onions, cilantro, Thai basil, and mint. Serve with lime, hoisin, and sriracha.
Notes
- Clear broth tip: The quick parboil + rinse keeps the broth clear and clean-tasting.
- Time saver: If you only have 2 hours, it’ll still be delicious—just slightly less intense.
- Make ahead: Chill overnight and remove any hardened fat before reheating.
- Salt & fish sauce: Start light and adjust. Lime juice at the table brightens without extra sodium.
- Noodle texture: Rinse cooked rice noodles briefly in cool water to stop cooking and prevent clumping.
