Why is Grilling the Best Way to Cook Costco King Crab Legs?  

You can cook king crab legs in several ways. Yet, grilling can prove the best way to enjoy the delicious king crab legs. Here are a few reasons:

Flavor enhancement

Grilling imparts a unique smoky flavor to the crab legs that you don’t get with other cooking methods. The high heat also caramelizes the natural sugars in the crab meat. It enhances its natural sweetness and creates a delicious contrast with the smoky flavor.

Besides this, the leg shells are also rich in flavors. When you allow them to kiss flames, this flavor is directly released into the meat.

Even cooking

The direct heat of the grill ensures that the crab legs are cooked evenly from all sides. The exposed meat is also cooked quickly, resulting in a tender and juicy texture.

Infusion of seasonings

Grilling allows you to baste the crab legs with melted butter or other seasonings during the cooking process. You add these seasonings directly into the exposed meat of crab legs.

Unlike other processes like steaming, grilling allows you to infuse the additional flavors into the meat as much as you want. This enhances the overall taste and aroma of the dish.

More aesthetic appeal

Grilling gives the crab legs an appetizing, slightly charred appearance that adds to their visual appeal. The bright orange-red color of the cooked shells also adds to the presentation.

Fun-filled cooking experience

Grilling king crab legs is a great way to enjoy outdoor and indoor cooking and dining–it’s a fun and interactive cooking method. 

How? 

Since the king crab legs are already cooked, you can also grill them on K-BBQ grills indoors or arrange fun cooking in your backyard.

Hence, you can enjoy it with your friends and family–it becomes a memorable dining experience.

However, ultimately, the “best” way to cook king crab legs depends on your personal taste and the experience you’re looking to create.

What Part of King Crab Legs Should You Grill?

When grilling king crab legs, you’ll want to focus on the largest, meaty sections of the legs. These are typically found in the following parts:

Merus

The merus is the largest segment of the crab leg and the best part to grill.

It’s located closest to the body of the crab. It has the most meat and is the most prized part of the leg. The thick, tender meat from this section is ideal for grilling.

However, the grilled portion from this part is less aesthetically pleasing. Another reason is that you can’t add much seasoning to it if you love basting the seasoning repeatedly during grilling.

Carpus

The carpus is the middle segment of the leg and has a good amount of meat. The meat in this section is still quite tender and flavorful. You can also grill it if your king crab legs are extra large. So, overall, it’s also suitable for grilling.

Propodus

The propodus is the third segment of the leg, and while it has less meat than the merus and carpus, it can still be grilled if you love exploring the meaty shells in leisure. But, you can cut the shell to expose meat for infusing the seasonings during grilling.

Dactylus

The dactylus is the last and smallest segment of the leg, also known as the “foot” or “tip.” It has little meat and can be challenging to grill because of its size. 

It’s generally not the focus when grilling king crab legs, but if you’d like, you can still cook and serve it alongside the other sections only to keep it aesthetically appealing.

To put it simply, the merus is the preferable part to grill. You can cook other parts using some other cooking methods. 

How should you Cut and Prepare Costco Red King Crab Legs for Grilling?

You can’t simply thaw and grill the king crab legs. Before resting them on grill grates, you must prepare them so that they pick the seasonings easily.

You can prepare and cut the king crab legs by following these steps:

Thaw the crab legs

If you’re working with frozen crab legs, make sure to thaw them thoroughly in the refrigerator for at least 8 hours or overnight. 

If you don’t have enough time, you can also put them under cold running water for about 30-60 minutes. Please avoid putting them in cold water in a pot; it won’t be helpful.

Also, remember that using a microwave is not a good idea because it’ll treat the carbs the same way as it does to your food. Uneven thawing will result in disgusting cooking–would you love to ruin the precious meat?

Rinse and pat dry

Whether the crab legs are already cleaned or not, rinse them under cold running water. It’ll get you shiny clean crab legs by removing any debris or residue.

Then, pat them dry with paper towels.

Cut with kitchen shears and expose the meat.

No… please don’t hold your knife–the best tool for cutting king crab legs is a pair of sturdy kitchen shears. With the help of kitchen shears, you can cut through the tough shell without damaging the delicate meat inside. Here is how to do it properly.

  • Hold the crab leg firmly with one hand, and with the other hand, use the kitchen shears to cut along the length of the shell. 
  • Start from the thicker end and work your way toward the thinner end. Please follow the natural curve of the leg. Be careful not to cut too deep, as you don’t want to slice through the meat. Your only aim is to expose the meat so that you can brush the drip seasoning on them.
  • Once you’ve made a lengthwise cut along the shell, gently pry the shell open to expose the crab meat. Use your fingers or a small knife to carefully separate the shell from the meat. It’ll make it easier to season the meat and ensure even cooking.
  • Inspect the exposed crab meat for any cartilage or membrane that may be present. If you find any, carefully remove it with your fingers or a small knife.

Once the king crab legs are properly cut and prepared, they’re ready to be seasoned and grilled according to your preferred recipe.
