How to Reheat Crab Legs
Crab legs can be reheated in virtually any appliance that radiates heat. Some methods take more time than others, but you will be pleased to know that even when reheating, if done properly, the crab legs will retain the suppleness that you love them for.
Storing Crab Legs
For the best results, you will want to make sure you store your leftover crab legs properly. They should be refrigerated in an airtight container within two hours of cooking. In the fridge, they can last for around four days.

Best Way to Reheat Crab Legs

For them to heat all the way through, it should only take around five minutes.
Reheating Crab Legs by Steaming Them
Steaming your crab legs is a similar method to boiling them. The biggest difference is that using this technique requires much less water. Again, it only takes a few minutes so it is pretty convenient.
To reheat crab legs by steaming them, just fill a steamer pot with enough water to cover the crab legs. A pot with a metal colander over it will work just as well if you do not have a steamer pot on hand. Cover the bottom with a couple inches of water.
Once the water gets to a boil, place the crab legs on top of the water and cover. Let them steam for about five minutes and you should be good. For added flavor, try adding beer, broth, or wine to the water.

Reheat Crab Legs on the Grill
Using a grill to reheat crab legs is especially convenient if you’re planning on eating them with a grilled side, like corn or potatoes. One appliance can cook your whole meal, and it can give the crab legs an added smoky flavor. To reheat crab legs on a grill, just heat the grill as you normally would.
You can then place the legs directly on the metal. One thing to know is that you must avoid putting the legs directly over the flames. This can cause them to dry out. With that being said, it only takes about ten minutes for crab legs to heat all the way through on the grill.

- Bake for 15 minutes, or 25 if the crab legs were frozen.
