How to Make Chilli Crab
-
Prepare the Crab: Start by cleaning the crabs. Remove the shell, gills, and crack the legs to allow the sauce to infuse the meat. Set aside to let the flavors develop.
-
Make the Spice Paste: Soak the dry red chillies in hot water for 10 minutes to soften them. Blend them together with chopped onions, garlic, and ginger until you achieve a coarse paste, preserving some shape for texture.
-
Prepare the Sauce: In a bowl, mix cornstarch with cold water to create a slurry. Set this aside along with the beaten egg. If using chicken stock cubes, dissolve them in hot water for rich flavor.
-
Cook the Crab: In a wok, heat the peanut oil over high heat. Add the spice paste and sauté for about 3-4 minutes until fragrant. Then, stir in salt and sugar, cooking for another minute. Add in the crabs along with the chicken stock, cover, and cook for 5-6 minutes until the crabs are fully cooked.
-
Add Sauces and Simmer: Stir in the red chilli sauce, soy sauce, and tomato ketchup. Replace the crab shells if desired, then cover and let simmer for an additional 4 minutes to deepen the flavors.
-
Finish the Dish: Slowly incorporate the cornstarch slurry into the sauce, followed by the beaten egg. Gently stir and simmer for about 30 seconds, or until the sauce thickens beautifully.
-
Serve: Garnish with fresh coriander leaves and serve hot, alongside steamed rice, toasted bread, or mantou to soak up that scrumptious sauce.
Optional: Pair with a squeeze of lime for an extra burst of freshness!

Expert Tips for Chilli Crab
-
Freshness Matters: Always use fresh crabs to enhance the flavor of your Chilli Crab. If using frozen, ensure they are fully thawed before cooking.
-
Get the Right Texture: When making the spice paste, blend it to a coarse consistency. This retains texture and allows for better flavor release during cooking.
-
Adjust Spice Levels: Be mindful of the amount of red chilli sauce you add. Start with less, as you can always add more to suit your spice tolerance without overpowering the dish.
-
Thickening Technique: Add the cornstarch slurry and beaten egg gently. Stir slowly to achieve a uniform sauce texture. Avoid boiling after adding the egg to prevent curdling.
-
Serving Options: Serve your Chilli Crab with fluffy steamed buns or rice. They will soak up the luscious sauce and balance out the dish perfectly.
Make Ahead Options
These Spicy Singaporean Chilli Crab preparations are perfect for home cooks looking to save time during busy weeknights! You can clean the crabs and prepare the spice paste up to 24 hours in advance, storing them separately in the refrigerator. The spice paste can stay fresh in an airtight container, preserving its vibrant flavors. For a smoother process, you can also pre-measure and mix the sauce ingredients (minus the cornstarch and egg) ahead of time, ready to be combined just before cooking. When it’s time to serve, simply heat the peanut oil, add your pre-prepped spice paste and sauce, cook the crabs, and finish with the cornstarch slurry and egg for a dish that’s just as delicious as if made from scratch!
How to Store and Freeze Chilli Crab
Room Temperature: Chilli Crab is best enjoyed fresh, but if needed, it can be left at room temperature for up to 2 hours before serving.
Fridge: Store any leftover Chilli Crab in an airtight container for up to 3 days. Reheat gently on the stove over low heat to preserve the sauce’s texture.
Freezer: If you need to freeze Chilli Crab, do so without the sauce for optimal quality—store in a freezer-safe container for up to 2 months. Thaw completely before reheating.
Reheating: When ready to enjoy the leftovers, reheat in a saucepan over low heat, stirring gently to avoid separation of the sauce.
What to Serve with Chilli Crab?
Creating a memorable meal goes beyond just the main dish—it’s about the perfect pairings that bring everything together.
-
Steamed Rice: This classic side absorbs the rich, tangy sauce beautifully, making each bite a delightful experience. Fluffy rice balances the crab’s bold flavors, enhancing the overall enjoyment.
-
Toasted Bread: Crunchy, warm slices perfectly complement the luscious sauce. They invite you to savor every drop, giving a satisfying texture alongside the tender crab meat.
-
Mantou (Chinese Steamed Buns): These soft, pillowy buns are traditional accompaniments that soak up the sauce wonderfully. They add a delightful, cloud-like contrast to the spiciness of Chilli Crab.
-
Stir-Fried Vegetables: A fresh medley of colorful vegetables provides a crunchy texture and a vibrant touch to the meal. Their light, crisp nature counterbalances the heaviness of the crab sauce, creating a well-rounded plate.
-
Cucumber Salad: This refreshing salad, tossed with a vinegar dressing, adds a crisp and tangy counterpoint to the rich flavors of the crab. The coolness of cucumber helps cleanse the palate.
-
Beer or White Wine: A chilled, crisp white wine or a light beer enhances the dining experience. Their refreshing qualities complement the spice without overpowering the vibrant flavors of the dish.

Chilli Crab Recipe FAQs
How do I choose the best crabs?
Absolutely! When selecting crabs, look for ones that are lively with a firm shell, indicating freshness. Mud crabs and Dungeness crabs are excellent choices. If you see dark spots all over the shell, it’s best to avoid those.
What’s the best way to store leftover Chilli Crab?
For sure! Store your leftover Chilli Crab in an airtight container in the fridge for up to 3 days. Reheat gently on the stove over low heat, stirring occasionally to keep the sauce from separating.
Can I freeze Chilli Crab?
Yes, you can! Although I recommend freezing the crab without the sauce for better quality. Pack in a freezer-safe container and it’ll keep fresh for up to 2 months. To enjoy it again, thaw completely in the fridge and reheat on low.
What if my sauce is too thin?
No worries! If your sauce turns out too thin, simply create a cornstarch slurry by mixing equal parts cornstarch and cold water. Stir it into your simmering sauce gradually until it reaches the desired thickness. Simmer for a couple of minutes to activate the cornstarch fully.
Is Chilli Crab suitable for a gluten-free diet?
Very much so! You can easily make this dish gluten-free by substituting soy sauce with tamari and ensuring any additional condiments you use are also gluten-free. Always check labels for potential allergens!
How can I adjust the spice level?
Of course! Start with the amount of red chilli sauce and dry red chillies recommended. Taste as you go and feel free to add more heat if you love a spicy kick. You can also reduce the chilli sauce or omit the dry chillies for a milder flavor.
