Can You Reheat Crab?

Yes, you can reheat crab, but it is one of the most heat-sensitive seafoods you can work with. Crab muscle fibres are fine-grained and tight, and they firm rapidly when overheated. The difference between perfectly reheated crab and dry, rubbery crab is a matter of minutes and temperature. The fix is consistent: gentle heat, a moisture source, and stopping early.

Can You Reheat Crab?

Yes, with care. Cooked crab keeps in the fridge for two to three days in a sealed container. It should be refrigerated within one hour of cooking. Crab is a higher-risk shellfish, so reheat to 63°C (145°F) throughout and do not reheat more than once. Crab meat that was previously frozen and thawed should not be refrozen after reheating. Do not reheat raw crab: cook it fully first.

Reheating Crab by Steaming

The best method. Steam provides even, gentle heat that warms the meat without the direct contact that causes drying.

1. Set up a steamer basket over simmering water.
2. Place the crab legs or claws in the basket. For whole crab, you may need to work in sections.
3. Cover and steam for five to seven minutes for legs and claws, or eight to ten minutes for a whole crab.
4. The shell will be hot to the touch and the meat inside should be warm throughout.

Adding a splash of white wine or a sprig of tarragon to the steaming water adds a subtle flavour that improves the result slightly.

Reheating Crab in the Oven

Good for whole crab or large sections where a steamer isn’t practical.

1. Preheat the oven to 150°C (300°F).
2. Place the crab in an oven-safe dish and add two to three tablespoons of water or white wine.
3. Cover tightly with foil to trap steam.
4. Heat for 8 to 12 minutes. Do not exceed this: crab dries out quickly once overheated.

Reheating Crab in the Microwave

Faster but less even. Acceptable for crab meat out of the shell (in a crab cake, crab dip, or pasta).

• 50% power only
• Place in a microwave-safe dish with a tablespoon of water
• Cover with a damp paper towel
• 30-second bursts, checking between each
• Two to three minutes maximum for a standard portion

What Not to Do

Do not re-boil crab. Boiling was the original cooking method and boiling again pushes the internal temperature well above what is needed, making the meat tough and releasing more of the volatile compounds responsible for a strong shellfish smell. The same logic applies to microwaving at full power or using a very hot oven.

Which Method Should You Use?

Q: My daughter just recently visited Maine and brought back some of the most delicious crab legs I have ever had in my life. At dinner, we had no leftovers, so this is more of a future question. If I were to order crab legs, could I make a batch for a large dinner party? We were hoping to substitute turkey this year at Thanksgiving!

A: Oh yum! Crab is a delicious meal any time of the year and reheating it to perfection is quite easy. Now, you need to be sure to note that when you purchase crab, it has already been cooked then flash frozen. When you purchase the crab at the store, it has been cooked once already, so the preparation for crab, it’s really just choosing which method of reheating you like best!

Steaming Method

Steaming crab legs are one of the easiest ways to reheat them. Simply bring water to a boil and place a steamer pot on the top (like what you would use for asparagus) place the legs in the pot and cover. Once you can smell them, they are done. Of course you can always use a meat thermometer, the desired degree should be 135 degrees F.

Oven Method

When you are looking to cook a large batch of crab legs, the oven will be your best bet for the simple fact you can fit more. To reheat crab legs in the oven, spread them in an oven safe dish, and add about a 1/8 of an inch of water to the bottom. Cover with aluminum foil, ensuring it is snug on the pan, and place in a 350 degree F oven. This is a large scale steaming process so the tighter the aluminum foil, the better!

Allow the legs to cook for about 7 to 10 minutes, be careful not to overcook them!

The Microwave

While many people are rather against the microwave, it is a great time saver as long as you know how to use it.

Crab legs are not too hard to reheat in the microwave, in fact, you simply put them in a dish with one tablespoon of water to every 8 ounces. Microwave on high for 3 – 4 minutes. Handle carefully as the shells will be quite hot!

While many look to boiling their crab legs, it is not recommended for the simple fact of the crab meat is very delicate and can lose flavor in the rolling waters. Now, if you have whole crabs, you can boil them, but not crab legs.

Reheating seafood was once a daunting task, now we do not even have to think twice about it. With these three heating methods, you no longer need to go to a fancy restaurant to enjoy these oceans delights, just run on down to the market and pick up a few pounds just for yourself.
