Even among crustaceans, crab has a sweet taste that stands out, and Alaskan king crab is the best crab ever. It’s usually sold frozen and already cooked because the stormy and dangerous waters where it’s caught are too far from big markets for the fresh product to work. When thawed, whether at home or at the market, its highly perishable. If you cant eat it immediately, you can refreeze the crab, but only within some severe limitations.
When it comes to fresh crabs, the problem is that they don’t last long after being caught, and when they die, they go bad very quickly. Most companies that process crabs steam and blast-freeze them on the boat or as soon as the boats land so that the crabs’ flavors are at their best and freshest. That quick freezing is important because when the fluids in the crab’s muscles freeze, they turn into crystals that grow in the tray like a normal ice cube. This can rupture the cell walls in the crab legs, taking away texture and moisture. Fast freezing makes smaller crystals, minimizing physical damage to the crab meat.
Crab legs are a treasured delicacy for many seafood lovers. Their sweet, succulent meat is perfect for special occasions and feasts. However, life sometimes gets in the way of finishing an entire package of crab legs before they spoil. This leaves many wondering: can you safely refreeze crab legs after thawing them?
In this comprehensive guide, we’ll cover everything you need to know about refreezing crab legs, including best practices for thawing, freezing, storage times, and more. Read on for the complete low-down!
An Overview of Refreezing Thawed Crab Legs
The short answer is yes, you can refreeze previously frozen crab legs if you thaw and handle them properly. However, there are a few caveats.
First, only refreeze legs that have been continuously refrigerated at 40°F or below during thawing. Never refreeze crab legs left at room temperature for over 2 hours.
Second, know that the texture and moisture content of the crab meat will degrade slightly with each freeze-thaw cycle Refreezing is best reserved for legs you plan to use in cooked dishes, not serving cold.
Follow proper thawing, cooling, freezing and storage guidelines to safely preserve crab legs for later use.
Why Crab Legs Are Initially Frozen
To understand why proper freezing and thawing is so important with crab legs let’s first look at why they’re frozen in the first place
-
Prevents bacterial growth and spoilage.
-
Locks in freshness immediately after catching.
-
Allows time for shipping from remote fishing areas.
-
Reduces moisture loss and preserves texture.
Quick-freezing crab at sea maintains quality. Refreezing at home can diminish it if not done right.
Thawing Crab Legs Properly
Safe thawing is the first step in preserving refrozen crab legs. Never thaw legs at room temperature or in hot water as bacteria will grow rapidly.
The best thawing methods include:
-
In the refrigerator: Thaw overnight in 40°F or below refrigerator.
-
In cold water: Submerge sealed legs in cold tap water, changing water every 30 mins.
-
In the microwave: Use the defrost setting based on weight.
Thawed crab legs will keep 3-5 days in the fridge. Freeze immediately if you won’t use within this window.
How to Refreeze Crab Legs Correctly
Follow these steps for safely refreezing thawed crab legs:
-
Ensure legs were thawed properly in fridge or cold water, not room temp.
-
Refrigerate legs for no more than 5 days before freezing, if not used.
-
Package legs tightly in freezer bags, removing excess air.
-
Freeze at 0°F or colder as quickly as possible.
-
Label package with refreeze date and “previously frozen.”
-
Use within 3 months for best quality.
Again, never refreeze legs left out for over 2 hours or thawed improperly.
Storage Timelines for Frozen Crab
To retain top quality, abide by these frozen storage guidelines:
-
Unopened, store-bought frozen legs: 12 months
-
Thawed then refrozen legs: 3 months
-
Cooked frozen legs: 4 months
Track dates and labels closely. Discard if any off-odors, textures, or discoloration develop.
Impact of Refreezing on Quality
Refreezing crab legs can degrade texture and moisture in the meat through damage to cell structures. Signs of quality loss include:
-
Less firm, rubbery, or mushy texture
-
Dryness or loss of juiciness
-
Mildly altered flavor
-
Discoloration
Refreezing is harder on meat than initial freezing. Use refrozen legs in cooked dishes or sauces to offset this diminished quality.
Frequently Asked Questions
Confused about how to handle thawed and frozen crab legs? Here are answers to common questions:
Can you re-freeze crab legs thawed on the counter or in hot water?
No, only refreeze legs thawed in the refrigerator or cold water.
How do you know if thawed crab legs went bad?
Discard if you detect sour, ammonia, or rotten odors. Also pitch if texture or color seems significantly off.
Can you freeze cooked crab legs?
Yes, prepared crab legs can be frozen. Cool completely before freezing.
Is it safe to eat refrozen crab legs?
Yes, if properly thawed, stored, and refrozen. But expect some decline in meat quality.
How long do refrigerated crab legs last after thawing?
3-5 days max in the refrigerator before use or refreezing.
The Takeaway: Refreeze with Care
While less ideal than fresh crab, with care, previously frozen crab legs can be safely refrozen for later use. Be diligent with proper thawing, cooling, freezing, labeling, and storage times. Know that refreezing will degrade texture and moisture somewhat. Incorporate thawed then refrozen crab into cooked dishes or sauces to offset this quality loss and enjoy their sweet flavor.
Warming to the Idea
If youre going to keep the option of refreezing your crab, thawing it safely is absolutely critical. Dont thaw them at room temperature, or in a water bath. The only safe way to thaw them before putting them back in the freezer is in the fridge, where they will never get too hot. Thawed crab legs only last three days at most, so don’t thaw them until the day you want to cook them. If your plans change, refreeze the crab immediately to preserve its shelf life to the greatest degree possible. If youve bought the crab already thawed from a store, check the packing date. If its not dated for the same day, use the crab or discard it — dont refreeze it.
Aside from its unusual perishability, refrozen crab poses a serious question of quality. The first step in freezing was done in a commercial blast freezer, which doesn’t hurt the meat too badly. However, your home freezer doesn’t work as quickly. When you freeze king crab again, the meat crystals get bigger, which breaks down the cell walls more. The flesh will become softer, and the extra water can make the crab drier than it was after the first thaw in the fridge. This is why Alaskas Seafood Marketing Institute advises against refreezing crab legs. You can make up for the low quality, though, by being creative with how you use the legs once they’re thawed.
Always mark the packages of refrozen crab so you know what youre working with. If you still wish to serve the legs in their shells, consider cooking them directly from the freezer. You’ll have to give them a few more minutes to reheat, but skipping the thawing step makes the food safer and keeps some of the crab’s quality. You could also let the legs thaw in the fridge and then add the meat to your favorite soup, sauce, risotto, or pasta dish right before it’s done. Putting crab meat in a sauce hides any loss of moisture, and adding different textures like rice or pasta helps hide any problems with the crab’s texture.
