Ceramic roaster okay in freezer?

[Raera]

It's not an expensive one, but the perfect size for Boxing Day fish pie.
It says microwave safe and oven up to 250, freezer not mentioned. Is it likely to crack as the food expands when it freezes?
Thanks!

Not ceramic but I've put glass Pyrex roasters in the freezer and they have been fine, just make sure the fish pie is fully defrosted and up to room temperature before putting it in the oven.

I’d not risk it tbh.
