What Are Frozen Crab Legs?
Frozen crab legs are typically made from snow crab, king crab, and Dungeness crabs. These pre-cooked items can be found in the frozen seafood section of your grocery store or online. They are convenient because they have already been cooked before being frozen, which means that you don’t need to worry about boiling them for hours before eating.

Benefits Of Cooking Frozen Crab Legs
Cooking frozen crab legs offers several advantages. They are much cheaper than fresh crab legs, and they’re also easier to prepare. You can also save time by not having to wait for the crab to cook all the way through. Plus, because they have already been cooked once, there is less chance of foodborne illness if you don’t overcook them.
