Tết Bún Bò Huế (Spicy Vietnamese Noodle Soup)
Why this recipe works
- Cleaner, richer broth: Blanching and rinsing the meat before the main simmer removes excess scum, helping the broth taste clean while still drawing flavour from the bones and pork.
- Layered aromatics: Lemongrass, ginger and onion perfume the base, while shrimp paste and fish sauce add the deep savoury character associated with bún bò Huế.
- Signature chilli finish: Warming chilli oil with annatto before stirring it into the broth gives the soup its fragrant heat and recognisable red-orange colour.
Get the most out of this recipe
Adjust the heat
- For less heat: Use less chilli oil in the broth and let diners add extra at the table if they want more spice.
- For a hotter bowl: Increase the chilli oil gradually after the broth is seasoned, tasting as you go so the heat does not overpower the lemongrass and savoury notes.
- Keep the heat balanced: Lime, herbs and spring onion are important at the end; they keep the broth lively rather than simply hot.
Authenticity notes
- Huế-style character: Bún bò Huế is known for a more assertive broth than many Vietnamese noodle soups, with lemongrass, chilli and shrimp paste playing a central role.
- Fresh finishing elements: Herbs and lime are not just garnish; they cut through the richness of the beef and pork and brighten the final bowl.
Make-ahead tips
- Make the broth ahead: The broth can be cooked a day in advance, chilled, and reheated gently before serving.
- Keep noodles separate: Store broth and sliced meats apart from the rice vermicelli and herbs so the noodles do not soften in the liquid.
- Reheat gently: Bring the broth back to a steady simmer, then warm the sliced meat briefly in the hot broth before assembling the bowls.
Ingredient notes
- Shrimp paste: Shrimp paste gives the broth depth and a distinctive savoury edge; dissolving it in hot broth first helps it disperse evenly.
- Lemongrass: Bashing the stalks before simmering helps release their citrusy aroma into the broth.
- Annatto: Ground annatto mainly contributes colour and a gentle earthiness, helping create the soup’s characteristic chilli-tinted broth.

Ingredients
Instructions
- Halve the onion and slice the ginger. Bash the lemongrass with the side of a knife, then cut each stalk into 2 to 3 pieces.
- Put the beef shank and pork belly in a stockpot and cover with the water. Bring to the boil for 5 minutes, then drain and rinse the meat to remove scum; rinse out the pot too.
- Return the meat to the clean pot with the measured water, onion, ginger, lemongrass and fine sea salt. Bring to a gentle simmer, skim any foam, then cook partially covered for 2 hours, keeping the broth at a steady, quiet simmer.
- Lift out the pork belly and beef shank. Rest for 10 minutes, then slice the pork and thinly slice the beef; keep covered so it stays warm.
- Strain the broth back into the pot and return it to a gentle simmer. In a small saucepan, warm the chilli oil with the ground annatto for 1 to 2 minutes until fragrant, then stir this into the broth along with the shrimp paste and fish sauce; taste and adjust with a little more fish sauce or salt if needed.
- Cook the rice vermicelli in boiling water until tender, then drain well in a colander. Divide the noodles between bowls and top with the sliced beef and pork.
- Ladle the piping-hot broth over each bowl. Finish with sliced spring onion, fresh coriander and lime wedges for squeezing at the table.
Recipe notes
Tips
- Keep the broth at a gentle simmer rather than a rolling boil to maintain a clear, rich flavour.
- If you prefer a cleaner shrimp paste flavour, dissolve it in a few spoonfuls of hot broth first, then stir it back into the pot.
- This soup is best served straight away, but you can make the broth a day ahead and chill it, then lift off any solidified fat before reheating to a simmer.
Substitutions
- Replace Beef shank with Beef brisket for a slightly softer, shreddable texture.
- Replace Pork belly with Pork shoulder for a leaner bowl with less richness.
- Replace Chili oil with a smaller amount of Chili oil for a milder heat, then add more at the table to taste.
Storage
- Refrigerate up to 3 days
- Store broth and sliced meats separately from the rice vermicelli and herbs. Chill promptly, then reheat the broth to a gentle simmer until piping hot; warm the meat briefly in the hot broth and cook fresh rice vermicelli for the best texture.
