King crab legs are a luxurious treat, a culinary indulgence that promises succulent, sweet meat and a memorable dining experience. Purchasing them from Costco is a smart move, as they often offer competitive pricing on high-quality seafood. But once you have those magnificent legs in your possession, the question becomes: how do you cook them perfectly? Fear not! This comprehensive guide will walk you through everything you need to know to transform your Costco king crab legs into a feast fit for royalty.
Understanding Your Costco King Crab Legs
Before diving into the cooking process, it’s essential to understand what you’re working with. Costco typically sells pre-cooked, frozen king crab legs. This is a crucial point because it means you’re not actually cooking the crab, but rather reheating it. Overcooking can result in dry, rubbery meat, so the goal is to gently warm the legs without sacrificing their delicate flavor and texture.
The size and quantity of the king crab legs you purchase from Costco can vary. Pay attention to the packaging for information on weight and approximate leg count. This will help you determine how much you need per person. A general rule of thumb is about ½ to 1 pound of king crab legs per person, depending on appetites and what else you’re serving.
Finally, check the “use by” or “best by” date on the package to ensure freshness. While frozen crab can last for several months, it’s always best to consume it sooner rather than later for optimal flavor and quality.
Thawing Your King Crab Legs: The Right Way
Proper thawing is paramount to achieving perfectly reheated king crab legs. There are two main methods: the refrigerator method and the cold water method.
Refrigerator Thawing
This is the recommended method as it’s the safest and allows for even thawing. Simply place the frozen crab legs in a large bowl or container and transfer them to the refrigerator. Allow them to thaw for 24-48 hours, depending on the size and thickness of the legs.
The slow thawing process helps prevent moisture loss, resulting in more succulent meat. Plan ahead to ensure you have enough time for this method.
Cold Water Thawing
If you’re short on time, the cold water method is a faster alternative. Place the frozen crab legs in a large, resealable plastic bag, squeezing out as much air as possible. Submerge the bag in a bowl of cold water, changing the water every 30 minutes to ensure it remains cold.
This method typically takes 1-2 hours, depending on the size of the legs. Never use warm or hot water, as this can partially cook the crab and compromise its texture.
Important Note: Once thawed, king crab legs should be cooked within 1-2 days. Do not refreeze thawed crab legs, as this can negatively impact their quality.
Reheating Methods: Achieving Seafood Nirvana
Now for the main event: reheating your Costco king crab legs. There are several popular methods, each with its own advantages and disadvantages. We’ll cover steaming, baking, grilling, and boiling (or poaching).
Steaming: The Gentle Approach
Steaming is widely considered the best method for reheating king crab legs. It’s gentle, preserves moisture, and allows the crab to heat evenly.
To steam, fill a large pot with about 1-2 inches of water. Place a steamer basket or insert inside the pot, ensuring the water level is below the basket. Bring the water to a boil.
Arrange the thawed king crab legs in the steamer basket, being careful not to overcrowd them. Cover the pot tightly and steam for 5-8 minutes, or until the crab is heated through. The shells should be bright red and the meat should be warm to the touch.
For added flavor, you can add aromatics to the steaming water, such as lemon slices, garlic cloves, or bay leaves.
Baking: Simple and Convenient
Baking is another easy and convenient method for reheating king crab legs. It’s less likely to overcook the crab compared to boiling.
Preheat your oven to 350°F (175°C). Line a baking sheet with foil for easy cleanup.
Arrange the thawed king crab legs on the baking sheet. Drizzle with melted butter, olive oil, or a combination of both. You can also sprinkle with your favorite seasonings, such as garlic powder, paprika, or Old Bay seasoning.
Bake for 8-10 minutes, or until the crab is heated through. Check the internal temperature with a meat thermometer; it should reach 140°F (60°C).
Grilling: Smoky Flavor Infusion
Grilling king crab legs adds a delicious smoky flavor that complements the sweet crab meat. However, it requires a bit more attention to prevent charring.
Preheat your grill to medium heat. Lightly brush the grill grates with oil to prevent sticking.
Arrange the thawed king crab legs on the grill. Grill for 3-5 minutes per side, or until heated through, turning occasionally.
Keep a close eye on the crab legs to prevent them from burning. You can also wrap them in foil for the first few minutes to help retain moisture.
Boiling (or Poaching): A Quick Option, Handle with Care
Boiling, sometimes referred to as poaching, is the fastest method, but it also carries the highest risk of overcooking.
Bring a large pot of water to a rolling boil. Add salt and any desired aromatics, such as lemon slices or bay leaves.
Gently lower the thawed king crab legs into the boiling water. Cook for 3-4 minutes, or until heated through. Do not overcook!
Remove the crab legs immediately and drain well.
Important Note: When boiling, closely monitor the crab legs to ensure they don’t become rubbery. The goal is to simply reheat them, not cook them further.
Serving and Enjoying Your King Crab Legs
Once your king crab legs are perfectly reheated, it’s time to serve and savor the deliciousness.
Serve the crab legs immediately with plenty of melted butter, lemon wedges, and your favorite dipping sauces. Garlic butter, drawn butter, and cocktail sauce are all excellent choices.
Provide your guests with crab crackers or nutcrackers to help them break open the shells and extract the meat. Small forks or picks can also be useful for reaching those hard-to-get pieces.
Consider serving your king crab legs as part of a larger seafood feast, alongside shrimp, scallops, or other shellfish. Side dishes like steamed asparagus, corn on the cob, or a simple salad complement the rich flavor of the crab.
Don’t forget the napkins! King crab legs can be messy, but that’s part of the fun. Embrace the experience and enjoy every succulent bite.
Flavor Enhancements and Variations
While king crab legs are delicious on their own, there are several ways to enhance their flavor and create unique culinary experiences.
- Garlic Butter: Simmer minced garlic in melted butter for a few minutes to infuse the butter with a rich, garlicky flavor.
- Lemon-Herb Butter: Add lemon zest, chopped fresh herbs (such as parsley, dill, or thyme), and a squeeze of lemon juice to melted butter.
- Spicy Butter: Incorporate a pinch of red pepper flakes or a dash of hot sauce into melted butter for a touch of heat.
- Old Bay Seasoning: Sprinkle Old Bay seasoning on the crab legs before baking or grilling for a classic seafood flavor.
- Citrus Marinade: Marinate the crab legs in a mixture of lemon juice, olive oil, garlic, and herbs for a zesty and aromatic flavor.
- Asian-Inspired Glaze: Brush the crab legs with a glaze made from soy sauce, honey, ginger, and garlic for a sweet and savory twist.
Experiment with different flavor combinations to find your perfect king crab leg creation.
Choosing Your Dipping Sauces
The right dipping sauce can elevate your king crab leg experience to new heights. Here are some popular options to consider:
- Classic Drawn Butter: Simple and elegant, drawn butter is made by melting unsalted butter and skimming off the milk solids.
- Garlic Butter: As mentioned earlier, garlic butter adds a rich and savory flavor to the crab.
- Cocktail Sauce: A classic pairing for seafood, cocktail sauce is made from ketchup, horseradish, lemon juice, and Worcestershire sauce.
- Remoulade Sauce: A tangy and creamy sauce made with mayonnaise, mustard, capers, pickles, and herbs.
- Aioli: A Mediterranean sauce made with garlic, olive oil, and egg yolks.
- Sweet Chili Sauce: A sweet and slightly spicy sauce that adds a unique flavor dimension.
Don’t be afraid to get creative and experiment with different dipping sauces to find your personal favorites.
Troubleshooting: Common Issues and Solutions
Even with the best instructions, occasional issues can arise when cooking king crab legs. Here are some common problems and how to solve them:
- Crab Legs are Dry: This is usually caused by overcooking. Ensure you’re using a gentle reheating method like steaming and avoid prolonged cooking times.
- Crab Legs are Rubbery: Again, overcooking is the culprit. Reduce the cooking time and check the crab frequently for doneness.
- Crab Legs are Not Hot Enough: If the crab legs are not heating evenly, try rotating them during cooking or increasing the cooking time slightly.
- Crab Shells are Difficult to Crack: Use a sturdy crab cracker or nutcracker and apply firm, even pressure. You can also try scoring the shells with a knife before cracking them.
- Crab Meat Sticks to the Shell: This can happen if the crab legs are not properly thawed. Ensure they are completely thawed before cooking.
By following these tips and troubleshooting common issues, you can ensure a successful and delicious king crab leg experience every time.

The classic pairing for King Crab legs is melted butter, often with a squeeze of lemon. The rich, buttery flavor complements the sweetness of the crab meat perfectly. Clarified butter (ghee) is another excellent option as it has a higher smoke point and even richer flavor.
Beyond butter, consider serving your crab legs with a garlic aioli, a spicy cocktail sauce, or a creamy dill sauce. These sauces add different dimensions of flavor, from savory to tangy to spicy. Experiment to find your favorite combinations, but remember that the crab itself is the star, so don’t overpower it with overly strong sauces.

How do I properly crack and extract the meat from King Crab legs from Costco?
Use kitchen shears or crab crackers to carefully crack the shell along the seams of the legs. Start by making small cuts along the length of the leg, avoiding cutting the meat inside. Gently peel away the shell to reveal the succulent crab meat.
For the larger sections, such as the knuckles, use a crab cracker to break the shell and then carefully extract the meat with a fork or your fingers. Be mindful of small cartilage pieces within the leg segments and remove them before eating. Enjoy the sweet and delicate flavor of the King Crab!
