Ingredients You'll Need

Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.

  • 2 lbs Live or Fresh Crab (Dungeness or Blue) (cleaned and cracked)
  • 4 tbsp Chili Garlic Sauce (adjust to taste)
  • 2 tbsp Tomato Paste
  • 1 inch Ginger (minced)
  • 4 cloves Garlic (minced)
  • 2 tbsp Soy Sauce (low sodium)
  • 1 tbsp Oyster Sauce (my secret ingredient!)
  • 1 tbsp Brown Sugar (packed)
  • 1 cup Chicken Broth
  • 2 tbsp Cornstarch (mixed with 2 tbsp water)
  • 2 tbsp Vegetable Oil
  • 1 Eggs (lightly beaten (optional))

Step-by-Step Instructions

  1. 1

    Prepare the crab by ensuring it is cleaned and cracked into manageable pieces. This allows the sauce to penetrate the meat effectively, maximizing flavor in every bite. Use a heavy cleaver or kitchen shears to crack the shell.

    ~5 min

    Tip: If using live crab, humanely dispatch it before cleaning.
  2. 2

    Heat vegetable oil in a large wok or deep skillet over medium-high heat. The high heat is crucial for creating a flavorful base for the sauce. Ensure the wok is properly heated before adding the oil to prevent sticking.

    ~2 min

    Tip: A wok is ideal, but a large skillet will also work well.
  3. 3

    Add minced ginger and garlic to the hot oil and stir-fry for about 30 seconds, until fragrant. Be careful not to burn the garlic, as it will become bitter. The aroma of the ginger and garlic is a key indicator that they are ready.

    ~1 min

    Tip: Keep the ginger and garlic moving to prevent burning.
  4. 4

    Add chili garlic sauce and tomato paste to the wok and stir-fry for another minute. This step helps to deepen the flavors of the sauce. The sauce should start to thicken slightly.

    ~1 min

    Tip: Adjust the amount of chili garlic sauce to your spice preference.
  5. 5

    Pour in chicken broth, soy sauce, oyster sauce, and brown sugar. Stir well to combine all the ingredients. The oyster sauce adds a unique umami flavor, so don't skip it!.

    ~2 min

    Tip: Taste and adjust the seasoning as needed, adding more sugar or soy sauce to balance the flavors.
  6. 6

    Bring the sauce to a simmer and then gently add the crab pieces. Ensure the crab is submerged in the sauce as much as possible to allow for even cooking and flavor absorption. Turn the crab pieces occasionally.

    ~3 min

    Tip: Avoid overcrowding the wok; cook in batches if necessary.
  7. 7

    Cover the wok and cook for about 10-15 minutes, or until the crab shells turn bright red and the meat is cooked through. The cooking time will depend on the size of the crab pieces. The meat should be opaque and easily pull away from the shell.

    ~12 min

    Tip: Check for doneness by piercing the thickest part of the crab with a knife. The juices should run clear.
  8. 8

    Stir the cornstarch slurry and slowly pour it into the sauce, stirring constantly to thicken. The sauce should thicken to a glossy, gravy-like consistency. If the sauce is too thick, add a little more chicken broth.

    ~2 min

    Tip: Add the cornstarch slurry gradually to avoid lumps.
  9. 9

    Optional: Gently stir in lightly beaten egg (if using) into the sauce. This will create a silky smooth texture. The egg should cook almost instantly in the hot sauce, creating beautiful ribbons.

    ~2 min

    Tip: Whisk the egg well before adding it to the sauce for a smoother texture.
  10. 10

    Remove the wok from the heat and serve the Chili Crab immediately. Garnish with chopped cilantro or green onions, if desired. The crab should be served hot to fully appreciate the flavors and textures.

    Tip: Serve with fried mantou (Chinese steamed buns) for dipping into the delicious sauce.

How Do I Know It's Ready?

The crab is done when the shell turns bright red and the meat is opaque and easily pulls away from the shell. A knife inserted into the thickest part should yield clear juices.

Frequently Asked Questions

Yes, you can use frozen crab, but fresh crab will yield the best flavor. Make sure to thaw the crab completely before cooking.
