Can you keep crab legs as leftovers?

Crab legs are a delicious treat that many seafood lovers enjoy. However, they can also be expensive and it’s not always possible to eat them all in one sitting. This leads many people to wonder – can you keep leftover crab legs to enjoy later?

The Short Answer

Yes, you can keep cooked crab legs as leftovers. Properly stored in the refrigerator or freezer, leftover crab legs will stay fresh and safe to eat for several days up to a few months. The key is making sure to store them correctly.

How Long Do Leftover Crab Legs Last in the Fridge?

Cooked crab legs that have been refrigerated will keep for 3 to 4 days. It’s important to store them in an airtight container to prevent them from drying out. Make sure to place the container on a shelf toward the back of the fridge, rather than in the door where the temperature fluctuates.

Some signs that crab legs have gone bad and are no longer safe to eat include:

  • An ammonia odor
  • Slimy texture
  • Mold growing on them

As long as the crab legs have been continuously refrigerated and don’t exhibit any of these signs, they should be fine to eat within 3 to 4 days.

How to Store Leftover Crab Legs

Follow these tips for storing leftover crab legs in the refrigerator:

  • Pick all meat out of the shells and place in an airtight container, making sure the meat is in a single layer.
  • Fill the container with fresh cold water, covering the crab meat fully. This helps keep it moist.
  • Put the lid on the container and refrigerate immediately.
  • Change the water daily to keep it cold and fresh.
  • Use the crab meat within 3 to 4 days.

This method prevents the delicate crab meat from drying out in the fridge.

Can You Freeze Leftover Crab Legs?

Freezing is an excellent way to extend the shelf life of leftover crab legs. They will keep for 2 to 3 months in the freezer.

To freeze crab legs:

  1. Wrap clusters of crab legs tightly in plastic wrap or place in airtight containers or bags. Make sure all air is pressed out before sealing.
  2. Label the packages with the date.
  3. Freeze for up to 2 to 3 months.

For cooked crab meat, freeze in an airtight container completely covered by water or stock. Leave 1⁄2 inch of headspace to allow for expansion. Freeze for up to 3 months.

Thawing Frozen Crab Legs

Thaw frozen crab in the refrigerator overnight. Do not thaw at room temperature or in hot water, as this encourages bacterial growth. Once thawed, use within 1 to 2 days.

You can also reheat frozen crab legs directly from frozen. Steam them for 4 to 5 minutes until heated through.

Can You Refrigerate Crab Legs in the Shell?

It’s best to remove crab meat from the shell before refrigerating. Leaving crab legs fully in the shell can lead to faster spoilage.

  • Wrap clusters of legs tightly in plastic wrap to help retain moisture.
  • Place in an airtight container or bag, squeezing out excess air.
  • Refrigerate for no more than 2 days.
  • Check frequently for signs of spoilage like odor and slime.

For best quality and safety, remove crab meat from shells before refrigerating. The shells can harbor bacteria that causes the meat to deteriorate faster.
