Vietnamese beef hotpot with an aromatic broth of star anise, cinnamon, and lemongrass — sliced raw beef, vegetables, vermicelli, cooked at the table.
Lau bo as a hotpot category is southern Vietnamese, particularly Saigon and the south-central coast — hotpot culture in general arrived through Cantonese influence, while the spice profile (star anise + cinnamon + lemongrass) is the Vietnamese signature shared with pho. The dish became standard at family-celebration tables — birthdays, gatherings, mid-meal communal eating — from the mid-20th century onward. The variations are many: lau bo nhung dam (with vinegar broth), lau bo sate (with chilli-lemongrass paste), but the aromatic-spice version described here is the broad-tent default.
Saigon-and-south-coast beef hotpot. Char shallot and ginger over open flame — direct char, not roast — for the smoky base that separates this from a thin pho broth. Beef sliced 2mm against the grain, dunked 5 seconds in 95°C broth.
The broth is unmistakably Vietnamese rather than Cantonese or Sichuan: it smells of star anise and cinnamon up front, lemongrass at the side, and beef-marrow underneath, lightly sweet from rock sugar. Charred shallot and ginger give the depth that distinguishes this from a thin pho broth — but unlike pho, it's drunk by the spoonful between dunks rather than over noodles. Beef slices, dipped 5-10 seconds, stay rosy and tender; chrysanthemum greens taste herbaceous-bitter against the sweet broth. The fermented bean curd dip is the southern signature.
Charring shallot and ginger over an open flame is the load-bearing aromatic step — direct charring (not roasting) develops Maillard products on the skin that pho cooks call the signature smoky depth. Without it, the broth is thin and lemongrass-forward only. Spices toasted briefly, then bagged in cheesecloth: long-simmered loose spices over-extract bitterness. The simmer must stay below boil — 90-95°C — or the broth turns cloudy from agitation. Beef is sliced against the grain at 2mm so a 5-second dunk in 95°C broth is enough to cook it; thicker slices need longer and toughen.
Variations
Lau bo nhung dam (vinegar broth, eaten with rice paper and pineapple); lau bo sate (chili-lemongrass paste, hotter); the aromatic-spice version with star anise and cinnamon is the Saigon family-table default.

7 steps · 35 min active · 55 min waiting
- 16 min
Char 4 shallots and 1 thumb of ginger directly over a gas flame or under a broiler until skins blacken in patches, 5 minutes. Rub off the worst of the char and set aside.
- 22 min
Toast 3 star anise, 1 cinnamon stick, 4 cloves, 1 tsp coriander seeds, 1 tsp fennel seeds in a dry pan over medium heat for 90 seconds — fragrance rises. Tie in cheesecloth.
- 325 min
In a stockpot, combine 1.5kg beef bones (knuckle and marrow), 500g beef brisket or shank, 4L water, the charred aromatics, the spice bag, 4 stalks bruised lemongrass, 1 piece of dried tangerine peel. Bring to a simmer (never boil) and skim every 5 minutes for the first 20 minutes.
Watch outEnsure the broth simmers gently; boiling can make it cloudy.
- 45 min
Simmer uncovered 2 hours — broth reduces and clarifies. Season with 3 tbsp fish sauce, 2 tbsp rock sugar, salt to taste. Strain through fine mesh into the hotpot vessel. Slice the brisket thinly for the table.
Watch outTaste the broth before adding salt; it can become too salty quickly.

Slice 600g beef sirloin or eye of round against the grain into 2mm sheets — partial-freeze the meat 30 minutes first for clean slices. Arrange overlapping on a platter.

Vegetable platter: 200g water spinach, 200g chrysanthemum greens (tan o), 150g enoki mushrooms, 150g shiitake, 150g taro stem (bac ha), 200g rice vermicelli (cooked al dente). Sauce: nuoc cham (fish sauce, lime, sugar, garlic, chilli) and a side of fermented bean curd dip.

Bring the hotpot to the table on a portable burner at a steady simmer. Diners dunk raw beef slices for 5-10 seconds (still pink in the centre), then vegetables, then vermicelli into the broth. Eat with the dipping sauces and the simmered brisket. Top up broth as it reduces.
