I think I made a mistake?

So I froze a ton of leftover amazing eggplant parm I made a while ago. And I wanted to have some for dinner tonight, but I think I made a boo boo. Are you supposed to thaw the frozen parm before baking? I made individual portions, so its not a whole tray of it, and I just stuck it in frozen into the oven at 450ish. Is it gonna come out weird?
