Singapore Chilli Crab
Whole mud crabs cooked in a tangy, sweet, and mildly spicy tomato-chilli sauce — Singapore's most iconic seafood dish.
About This Recipe
Chilli Crab was invented in Singapore in the 1950s by Madam Cher Yam Tian, who cooked crabs in a chilli-tomato sauce at her roadside stall along the East Coast. The dish exploded in popularity and is now listed on CNN Travel's 'World's 50 Most Delicious Foods.' Whole mud crabs are cracked and stir-fried in a wok, then bathed in a glossy, egg-thickened sauce of tomato, sambal chilli, garlic, ginger, and a touch of vinegar and sugar for balance. It is served with fluffy mantou buns — essential for mopping up every last drop of the sauce, considered by many to be even better than the crab itself. Eating it is gloriously messy and communal.

Pro Tips
- →
Ask your fishmonger to clean and halve live crabs — this is much easier than doing it at home.
- →
The mantou buns can be steamed or deep-fried; deep-frying creates a more luxurious texture.
- →
Do not over-thicken the sauce — it should be glossy and coatable, not gluey.
- →
Taste and adjust salt at the very end — flavors concentrate as liquids reduce, and a final pinch of flaky salt sharpens the whole dish.
Variations
- •
Black pepper crab: replaces the chilli-tomato sauce with a black pepper and butter glaze.
- •
Salted egg crab: crab tossed in a rich salted egg yolk sauce.
- •
Use King prawns as a more affordable alternative to whole crab.
- •
Vegetarian: swap the protein for roasted king oyster mushrooms, smoked tofu or cooked chickpeas — adjust seasoning slightly upward to compensate.
Storage
Best eaten immediately. Leftover crab in sauce keeps for 1 day refrigerated; reheat gently in the sauce with a splash of water.
History & Origin
Chilli crab was created around 1956 by Madam Cher Yam Tian on the Singapore waterfront. Her husband Roland Lim later opened a restaurant and formally put it on the menu. It was declared part of Singapore's intangible cultural heritage and has been served to visiting heads of state.
Frequently Asked Questions
Is chilli crab very spicy?
It is mildly spicy — the sauce is predominantly sweet and savoury. Adjust sambal quantity for your preferred heat level.
What type of crab should I use?
Sri Lankan or Flower mud crabs are traditional. Dungeness or Blue crab work well as substitutes.
Can I make this ahead of time?
Yes — most of the components can be prepared up to a day in advance and refrigerated separately. Reheat gently and assemble just before serving so textures stay distinct.
What can I substitute if I don't have all the ingredients?
Stay close to the role each ingredient plays: swap aromatics for similar ones (shallot for onion, lime for lemon), and keep the fat-acid-salt balance intact. Spice blends can usually be approximated with what's in the cupboard.
