Choosing the Best Crab Legs for BBQ

When it comes to grilling crab legs, starting with the best quality seafood is key. Here’s how to select the finest crab legs for your BBQ feast, ensuring you get the most delicious and satisfying results.

Types of Crab Legs Suitable for BBQ

1. King Crab Legs
   • Size and Meat Quality: King crab legs are renowned for their large size and impressive meat quality. They have thick, succulent meat that’s perfect for grilling. Their size makes them easy to handle on the BBQ, and they offer a substantial amount of meat per leg.
   • Flavor Profile: King crab has a slightly sweet, rich flavor that pairs wonderfully with the smoky notes from the grill.
2. Snow Crab Legs
   • Size and Meat Quality: Snow crab legs are smaller than king crab legs but are still an excellent choice for BBQing. They have a delicate, sweet flavor and a firm texture that holds up well on the grill.
   • Flavor Profile: The meat is sweet and tender, making it a favorite among seafood lovers. They cook quickly, making them ideal for a fast and tasty BBQ treat.
3. Dungeness Crab Legs
   • Size and Meat Quality: Dungeness crab legs are another great option. While not as large as king crab legs, they are still substantial and packed with flavorful meat.
   • Flavor Profile: They offer a slightly nutty flavor, which complements the smokiness of the BBQ perfectly.

What to Look for in Fresh Crab Legs

1. Color and Appearance:
   • Fresh crab legs should have a bright, vibrant color. For pre-cooked crab legs (which is often the case), look for bright red shells.
   • Avoid crab legs with a dull, greyish color as this may indicate they are not fresh.
2. Smell:
   • Fresh crab legs should have a clean, briny smell, reminiscent of the ocean.
   • If they have a strong, fishy odor, it’s a sign they may not be fresh.
3. Texture:
   • The shells should be firm and unblemished. Soft or slimy shells can indicate poor quality or old crab.
4. Frozen Crab Legs:
   • If buying frozen, ensure they are fully frozen with no signs of thawing, which can compromise quality.
   • Check for ice crystals inside the packaging, which might indicate freezer burn.

Necessary Tools and Preparation

Before you start grilling your crab legs, it’s essential to gather the right tools and prepare your crab legs properly. Here’s what you’ll need and how to get your crab legs ready for the BBQ.

Tools You’ll Need

1. Grill: A gas or charcoal grill will work fine. Make sure it’s clean and ready to go.
2. Grill Tongs: For handling the crab legs on the hot grill.
3. Basting Brush: To apply butter or marinade to the crab legs.
4. Kitchen Shears: Useful for cutting through the tough shells.
5. Crab Cracker or Nutcracker: For cracking open the shells once they’re cooked.
6. Small Knife or Seafood Pick: To help extract the meat from the shells.
7. Aluminum Foil: For wrapping the crab legs if you choose to steam them on the grill.
8. Bowl for Discarded Shells: To keep your workspace clean.

How to Clean and Prepare Crab Legs

1. Thawing (if frozen):
   • If you’re starting with frozen crab legs, thaw them in the refrigerator overnight. For a quicker method, you can place them in a sealed plastic bag and submerge them in cold water for a few hours.
2. Rinsing:
   • Rinse the crab legs under cold running water to remove any sand or debris. This is especially important for fresh crab legs.
3. Inspecting:
   • Check the crab legs for any remaining pieces of shell or debris and remove them. Look for any damaged parts that may need to be trimmed.
4. Cracking the Shells:
   • Using kitchen shears, carefully cut along the length of the shell on each leg. This helps to open up the shell and makes it easier to remove the meat after grilling. Be careful not to cut through the meat.
   • If you prefer, you can partially crack the shells using a crab cracker or nutcracker. This will make it easier to eat the crab legs once they’re cooked, but still keep the shell mostly intact for grilling.
5. Marinating (Optional):
   • If you want to infuse extra flavor, marinate the crab legs before grilling. A simple marinade of melted butter, minced garlic, lemon juice, and your favorite herbs works beautifully. Brush the marinade over the crab legs and let them sit for about 15-20 minutes.
6. Wrapping (if steaming on the grill):
   • For a steaming effect, you can wrap the crab legs in aluminum foil. Add a little butter and seasoning inside the foil packet before sealing it. This method helps to keep the crab legs moist and flavorful.

BBQ Techniques for Crab Legs

Cooking crab legs on the BBQ can be done in several delicious ways, each bringing out unique flavors and textures. Let’s dive into the techniques of grilling and smoking crab legs, so you can choose the best method for your seafood feast.

How to Grill Crab Legs

Grilling crab legs is a straightforward method that adds a delightful smoky flavor and a bit of char. Here’s how to do it:

1. Preheat the Grill:
   • Set your grill to medium-high heat, aiming for a temperature around 350-375°F (175-190°C).
2. Prep the Grill Grates:
   • Clean the grill grates thoroughly and oil them lightly to prevent the crab legs from sticking.
3. Place the Crab Legs on the Grill:
   • Arrange the crab legs directly on the grill grates, ensuring they’re spread out evenly. If you’ve wrapped them in foil for steaming, place the foil packets on the grates.
4. Grill the Crab Legs:
   • Cook the crab legs for about 5-7 minutes per side. Since they’re usually pre-cooked, you’re essentially reheating them and adding a smoky flavor. If using foil packets, grill for about 10-12 minutes total, turning once halfway through.
5. Basting:
   • While grilling, baste the crab legs with melted butter or your chosen marinade. This helps to keep them moist and enhances the flavor.
6. Check for Doneness:
   • The crab legs are ready when the shell is bright red/orange, and the meat is steaming hot and opaque. Avoid overcooking as this can make the meat tough.
7. Serve:
   • Remove the crab legs from the grill, crack open the shells using a crab cracker, and enjoy with melted butter, lemon wedges, and your favorite dipping sauce.

Smoking Crab Legs on the BBQ

Smoking crab legs adds an extra layer of flavor, making them even more delectable. Here’s how to smoke crab legs on the BBQ:

1. Soak Wood Chips:
   • Choose a mild wood like apple, cherry, or alder for a subtle, sweet smokiness. Soak the wood chips in water for at least 30 minutes.
2. Preheat the Grill for Smoking:
   • Set up your grill for indirect heat. If using a gas grill, turn on one side to medium heat and leave the other side off. For a charcoal grill, push the coals to one side. Aim for a temperature around 225-250°F (110-120°C).
3. Prepare the Smoke Box:
   • Place the soaked wood chips in a smoker box or wrap them in aluminum foil with holes poked in the top. Place the smoker box or foil packet over the heat source.
4. Smoke the Crab Legs:
   • Place the crab legs on the cooler side of the grill, away from direct heat. Close the lid to trap the smoke inside.
5. Smoking Time:
   • Smoke the crab legs for about 25-30 minutes. Keep an eye on the temperature and adjust as necessary to maintain a steady heat.
6. Basting:
   • Occasionally baste the crab legs with melted butter or your preferred marinade to keep them moist and add flavor.
7. Check for Doneness:
   • The crab legs are done when the shell is bright red/orange, and the meat is hot and opaque.
8. Serve:
   • Remove the crab legs from the grill, crack them open, and savor the smoky, succulent meat with your favorite accompaniments.

Common Mistakes When Cooking Crab Legs on the BBQ

Cooking crab legs on the BBQ can be a breeze if you avoid these common mistakes:

1. Overcooking:
   • Mistake: Cooking crab legs too long, making them tough and dry.
   • Fix: Remember, most crab legs are pre-cooked. You just need to heat them through. Grill for about 5-7 minutes per side on medium-high heat.
2. Not Using Enough Heat:
   • Mistake: Using too low heat, leading to unevenly cooked crab legs.
   • Fix: Preheat your grill to medium-high (350-375°F). This ensures a quick, even cook and adds that desired smoky flavor.
3. Skipping the Basting:
   • Mistake: Not basting the crab legs, causing them to dry out.
   • Fix: Regularly baste with melted butter or marinade to keep the meat moist and flavorful.
4. Not Prepping the Shells:
   • Mistake: Leaving the shells completely intact, making it hard to get to the meat.
   • Fix: Use kitchen shears to cut along the length of the shell, making it easier to open after grilling.

Safety and Storage Tips

Handling seafood requires care to avoid contamination. Always keep raw crab legs refrigerated until ready to cook. Use separate cutting boards and utensils for seafood and other foods to prevent cross-contamination. Wash your hands thoroughly after handling raw crab.

For storing leftovers, refrigerate cooked crab legs within two hours of cooking. Place them in an airtight container or wrap them tightly in aluminum foil. Properly stored, they can last in the fridge for up to three days. If you need to store them longer, freeze them for up to three months. Reheat gently to avoid drying out the meat.
