As long as some part of it is still alive, it can regrow, but be aware that it will look rather shabby for quite some time as it recovers. Sometimes it is just easier to throw the plant out and replace it. Consider how much effort you want to invest.
To see if your succulent is still alive, check the leaves closest to the center. They will have some "bite" or snap if still alive. Think al dente pasta (but don't eat it, just bend the leaf ;) ). If they are dead, they will be flopy soft. If they are soft, check the base. Same thing. give it a squeeze and it should feel like the base is firm, not soft.
As long as some part is firm, the plant is alive and can make a recovery, with proper care. The biggest mistake people make with succulents is overcare, which will kill a damaged succulent. Water it properly (when the soil is dry) and keep it in good light. Keep an eye on the weather and do not let it get exposed to sub-freezing weather again.
Good luck with your plant!
