Recipe Overview

Cook Time: 20 minutes
Total Time: 40 minutes
Servings: 4
Yield: Variable, depending on crab size
Dietary Type: Pescatarian

Ingredients

12-14 blue crabs, live (substituting 2 live Dungeness crabs, about 3 pounds each OK)
1 cup peanut oil, for frying
2 cups flour (seasoned with salt and freshly ground black pepper)
6 tablespoons butter
6 tablespoons olive oil
3 stalks lemongrass, fresh (grassy tops discarded and bulbs finely chopped)
4 tablespoons garlic, minced
2 tablespoons hot pepper flakes
3 inches gingerroot, fresh, peeled and julienned
2 tablespoons tomato paste
3 tablespoons kosher salt
3 tablespoons sugar
1 bunch green onion, finely chopped
4-5 serrano chilies, sliced into thin rounds (optional)

Equipment Needed

Large Steamer or Pot for Steaming Crabs
Large Skillet or Wok
Tongs
Paper Towels
Mallet or Heavy Knife
Cutting Board

Instructions

First, steam the crabs. This can be done in a large steamer or pot. Steam until the crabs turn bright red, about 10-15 minutes depending on the size.
Once the crabs are cool enough to handle, remove the top shells.
Next, clean the crabs by pulling out the spongy gills and any opaque matter in the center of the body.
Flip the crab over and remove the key (the small flap on the underside).
Using a mallet or the edge of a heavy knife, cut each crab into 2 pieces. Make a crack in each crab piece, but don’t cut all the way through. This will help the flavors penetrate.
In a large skillet or wok, pour in the peanut oil to a depth of about 1 inch. Heat the oil over medium-high heat. The oil is ready when a small piece of flour sizzles immediately when dropped in.
Carefully fry the top shells of the crabs in the hot oil, turning until they are bright red and crisp. This takes about 2-3 minutes per side. Drain on paper towels and set aside. These are for presentation later.
Dredge the crab pieces in the seasoned flour, ensuring they are evenly coated.
Carefully add the dredged crab pieces to the hot oil and fry over fairly high heat, turning frequently for 5 to 6 minutes, or until golden brown and crispy.
Remove the fried crab pieces to paper towels to drain. Discard the used cooking oil or save for another frying purpose.
Place the skillet or wok back on medium heat and add the butter and olive oil.
When the butter is melted and the mixture is hot, add the lemongrass, garlic, pepper flakes, and ginger. Sauté for about 1 minute, until fragrant. Be careful not to burn the garlic.
Add the tomato paste, mix well, and cook for 1 minute, stirring constantly to prevent sticking.
Add the kosher salt and sugar and simmer for 2 minutes, stirring until the sugar is dissolved and the sauce is slightly thickened.
Add the fried crab pieces (not the top shells) and stir to coat the crab pieces thoroughly with the sauce.
Cook, stirring often, for 4 to 5 minutes, allowing the crab to absorb the flavors of the sauce.
Add the green onions and serrano chilies (if using) and remove from heat.
For a beautiful presentation, arrange the crab pieces back in the shape of the crab on a serving platter.
Divide ¾ of the pan juices over the arranged crab pieces.
Place the top shells back on top of the arranged pieces, pouring the remaining juices over the shells.
Serve immediately.

Expert Tips & Tricks

For an extra layer of flavor, marinate the crab pieces in a mixture of soy sauce, fish sauce, and a touch of sesame oil for about 30 minutes before dredging them in flour.
If you prefer a less spicy dish, reduce the amount of hot pepper flakes or omit the serrano chilies altogether.
Don’t overcrowd the pan when frying the crab. Fry in batches to maintain the oil temperature and ensure even cooking.
If you don’t have fresh lemongrass, you can use lemongrass paste, but the flavor won’t be quite as vibrant.
To ensure the crab is cooked through, the internal temperature should reach 165°F (74°C).

Serving & Storage Suggestions

This Vietnamese Stir-Fried Crab is best served immediately while it’s hot and crispy. The vibrant flavors pair perfectly with steamed rice or rice noodles. A crisp, cold beer or a light, fruity white wine would complement the dish beautifully.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the crab in a skillet over medium heat, stirring occasionally, until heated through. Reheating in the oven is also an option. Avoid microwaving, as it can make the crab rubbery.

FAQs (Frequently Asked Questions)

Q: Can I use frozen crab for this recipe?

A: While fresh crab is always preferred, you can use frozen crab if it’s not available. Make sure to thaw it completely before cooking, and pat it dry to remove excess moisture.

Q: What if I don’t have a wok?

A: A large skillet will work just fine. Just make sure it’s large enough to accommodate all the crab pieces without overcrowding.

Q: How do I know when the crab is done frying?

A: The crab is done when it’s golden brown and crispy on the outside and heated through. The internal temperature should reach 165°F (74°C).

Q: Can I make this dish ahead of time?

A: While it’s best served immediately, you can prepare the sauce ahead of time and store it in the refrigerator for up to 2 days. When you’re ready to cook, simply fry the crab and toss it in the sauce.

Q: What kind of peanut oil should I use?

A: Refined peanut oil is best for frying because it has a high smoke point.
