Lasagne bake or freeze first?

Just weighing in .... bake then freeze ...

Freeze then bake.

So funny you asked. I just pulled one out of the freezer for dinner tonight.
I have done both, but I prefer to freeze before baking. Wrap the whole Pam with aluminum fool then plastic wrap.
You don't need to defrost first. Just put in the oven before preheating. At a lower temp 325ish for an hour and then an hour at 350. Perfect every time!!!

I always bake first.

You can do either

Freeze, tightly wrapped.
Defrost before baking. Enjoy! :)
