Chili crab is Singapore's crowning culinary glory — whole crabs smothered in a thick, glossy sauce that balances chili heat, tomato sweetness, and tangy vinegar. You eat it with your hands and mop up the sauce with mantou buns.
Asian cuisine encompasses an incredible diversity of techniques and flavors. This recipe draws on time-tested methods to create something truly delicious.
The flavors in this dish reflect centuries of culinary tradition, adapted for the modern home kitchen. What makes Singaporean Chili Crab special is the balance — every element serves a purpose, and the interplay between ingredients creates something greater than any single component. With the right technique and a few key ingredients, you can achieve restaurant-quality results at home.
The key to nailing this dish is proper heat management and timing. Start with your protein at room temperature, season generously at every stage, and resist the urge to rush. Let each component develop its flavor fully before moving to the next step — patience here pays off enormously in the final result.
Ingredients
- 2 whole mud crabs or Dungeness crabs, cleaned and cracked
- 4 tbsp sambal oelek or chili paste
- 1/2 cup ketchup
- 2 tbsp rice vinegar
- 2 eggs, beaten
- 1 tbsp cornstarch mixed with 2 tbsp water
Instructions
- 1
Clean crabs, remove top shell and gills. Crack claws with the back of a cleaver.
- 2
Heat oil in a large wok. Fry garlic and ginger until fragrant, then add chili paste and stir-fry 1 minute.
- 3
Add ketchup, rice vinegar, sugar, and 1/2 cup water. Bring to a simmer.
- 4
Add crab pieces, toss to coat, cover and cook 8-10 minutes until shells turn red.
- 5
Drizzle in beaten eggs while stirring gently — they should form silky ribbons. Thicken with cornstarch slurry. Serve with fried mantou buns.

Tips & Storage
Pro Tips
Use live or very fresh crabs for the best flavor and texture.
Serve with fried mantou buns to soak up the incredible sauce — this is essential.
Let the protein rest for 5-10 minutes after cooking to allow the juices to redistribute for maximum tenderness.
Season each component individually rather than seasoning at the end — this builds deeper, more complex flavor throughout.
Storage
Best eaten immediately. The crab dries out quickly when stored.
Reheating
Reheat in a 350°F oven for 15-20 minutes until warmed through, or microwave individual portions for 2-3 minutes. Add a splash of broth or water to prevent drying. Stovetop reheating over medium-low heat is also effective.
Recipe Notes from Our Kitchen
Editor's Note
Editor's note: Do not skip the resting step at the end. It makes a bigger difference than any single ingredient in the recipe. Five minutes of patience pays off in juiciness and flavor.

Frequently Asked Questions
- What kind of crab should I use?
- Sri Lankan mud crab is traditional. Dungeness or blue crab work well as substitutes.
- Why add egg to the sauce?
- The beaten egg creates silky ribbons that thicken the sauce and add richness.
- Can I make this ahead of time?
- Yes — prepare up to the final cooking step, refrigerate, then finish cooking when ready to serve. Most dishes actually benefit from a rest in the fridge as the flavors have time to meld.
- How do I know when it is done?
- The most reliable method is an instant-read thermometer. For chicken, look for 165°F internal. For beef, 130°F for medium-rare, 140°F for medium. For pork, 145°F. Visual cues include clear juices and firm-to-the-touch texture.
