Can You Freeze Crab Legs?

Yes, you can absolutely freeze crab legs for long-term storage. When frozen properly, crab legs can maintain quality and freshness for several months in the freezer. Freezing prevents bacteria growth and decomposition that leads to spoilage. It also locks in moisture, texture, and taste.

Almost all types of crab legs freeze well, including snow crab legs, king crab legs, and Dungeness crab legs. The key is quickly freezing them soon after purchase and storing them consistently at 0°F or below.

How Long Do Crab Legs Last in the Freezer?

Most crab legs will keep well in the freezer for 3 to 4 months. Here are some more specific timelines for freezing different varieties:

  • Snow Crab Legs: Freeze for up to 3 months
  • King Crab Legs: Freeze for up to 6 months
  • Dungeness Crab Legs: Freeze for up to 3 months
  • Soft Shell Crab Legs: Freeze for up to 8 months

The freezer storage life can vary a bit based on preparation method. Crab legs frozen in the shell tend to last slightly longer than shelled crab leg meat. Vacuum sealed packages also maintain quality for longer versus freezer bags.


No matter the type, crab legs frozen longer than the recommended time frames risk declining in quality. The texture may become gummy and watery, and flavor can suffer. It’s best to stick within the safe storage guidelines for each variety.

How to Freeze Crab Legs?

Freezing crab legs allows you to enjoy their fresh, delicious taste long after purchasing them. The best way to freeze crab legs is discussed as follow:

  • Clean the crab legs thoroughly, rinsing under cold water. Gently pat dry with paper towels. Make sure the shell is intact and legs are not cracked.
  • Carefully arrange the crab legs in a single layer on a baking sheet or flat container. Place in the freezer for 1-2 hours until completely frozen solid.
  • Transfer the frozen legs to airtight freezer bags or containers, removing as much air as possible before sealing. This prevents freezer burn which can degrade texture and taste.
  • Label the containers clearly with the type of crab and date frozen. Include any other important information like where they were caught. Proper labeling allows you to efficiently track storage times.
  • For best quality, store frozen crab legs at 0°F or colder. Consistent ultra-low temperature preserves freshness for longer periods.
  • When ready to use, thaw frozen crab legs overnight in the refrigerator. This slower thawing ensures meat stays tender and juicy. You can also thaw in the microwave using the defrost setting if pressed for time.
  • Cook thawed crab legs as desired, though brief steaming is recommended to prevent overcooking and drying out. Enjoy your thawed crab legs within a day or two for peak flavor and texture.
  • Properly freezing and thawing crab legs makes it easy to enjoy their succulent seafood taste months after purchasing.

Can You Freeze Crab Legs in the Shell?

Yes, freezing crab legs in the shell is perfectly fine. Leaving the shell on helps retain moisture, safeguarding delicate crab meat during freezing. Ensure the legs are fresh and clean. Arrange them on a baking sheet, freeze until solid (1-2 hours), then transfer to airtight containers, removing excess air to prevent freezer burn. Label with type and freeze date, storing at 0°F. The shell preserves the crab meat’s integrity, allowing legs to go directly from the freezer to the pot for steaming or boiling, resulting in tender, juicy outcomes.

How to Cook Frozen Crab Legs

Cooking frozen crab legs while retaining their juiciness and flavor takes a bit of care. Properly thawing and choosing the right cooking method are key for success.

Thaw the Crab Legs Properly

For best results, thaw frozen crab legs overnight in the refrigerator. Place the unopened package on a tray or pan to catch any drips. This slow thawing in the fridge helps preserve texture and prevent excess moisture loss.

If pressed for time, you can quick thaw in the microwave using the defrost setting in short bursts, checking often to ensure they don’t start cooking.

Steaming Method


Steaming is highly recommended for cooking frozen crab legs. When determining how long to steam frozen crab legs, fill a large pot with 1-2 inches of water and bring it to a boil over high heat. Place a steaming basket or colander in the pot, making sure it sits above the water line. Arrange the thawed crab legs in a single layer in the basket. Steam the crab for 5-7 minutes, just until the flesh turns opaque. Resist the urge to oversteam, as the crab can quickly go from perfectly cooked to dried out.

Baking and Grilling Methods

You can also bake thawed crab legs at 375°F for 15-20 minutes. Line a baking sheet with foil and brush with butter or oil before adding legs in a single layer.

For a charred flavor, quickly grill or broil the steamed or baked crab legs for 2-3 minutes per side.

Seasoning Adds Flavor

Consider seasoning crab legs before cooking with seafood seasonings like Old Bay, minced garlic, lemon pepper, paprika, or fresh herbs. Brush with melted butter or olive oil to keep the meat moist and infuse with more flavor.

Check Doneness and Serve

Crab legs are cooked when the meat is opaque and separates easily from the shell. Be careful not to overcook. Transfer the hot crab legs to a serving platter and enjoy immediately with dipping sauces like drawn butter, aioli, or mustard sauce.

Can You Freeze Crab Legs After Cooking?

Yes, you can freeze crab legs after cooking them. This method involves extracting the cooked crab meat from the shells and vacuum sealing it. By following this approach, you can maintain the freshness of the crab meat for about three months. It’s a convenient way to prepare crab legs in advance, ensuring you have a quick and tasty seafood option whenever you desire.

Storage Tips for Freezing Crab Legs


Properly storing frozen crab legs is important to maintain quality and freshness over time. Here are some useful storage tips:

  • Use freezer bags or airtight containers when packing crab legs to prevent freezer burn. Squeeze out excess air before sealing to reduce ice crystal formation.
  • Arrange crab legs in a single layer when freezing to ensure fast, even freezing. Avoid stacking or overpacking bags/containers.
  • Label packages clearly with the type of crab, quantity, and date frozen. This allows for easy identification and rotation when using crab legs.
  • Place freshly frozen crab legs in the back of the freezer where the temperature is most consistent. Avoid temperature fluctuations from repeatedly opening the freezer.
  • Once frozen, maintain a constant freezer temperature of 0°F or below. Fluctuating temperatures can cause moisture loss and texture changes.
  • Avoid storing crab legs longer than recommended times for each type (3-4 months max for most crab). Use older packages first when grabbing crab to cook.
  • When handling frozen crab legs, keep them frozen until ready to thaw or cook. Minimize temperature spikes that could lead to partial thawing.


Freezing crab legs allows you to enjoy their sublime, sweet flavor long after they are in peak season. With proper freezing techniques, storage methods, and cooking practices, crab legs can retain their texture, moisture, and taste for months in the freezer. Follow the guidelines outlined here, like quick freezing soon after purchase, airtight packaging, and monitoring freezer temperatures. Thaw and cook frozen crab legs gently to prevent overcooking. Now you can savor tender, juicy, fresh-tasting crab legs in any season.
