I have made and subsequently frozen a large amount of Ragu sauce. I am intending to defrost the sauce to make a large lasagne on Thursday ready to cook and eat on Friday. If the lasagne is not all eaten is it ok to freeze the remainder immediately it cools?
as an ex-chef I wouldn't risk it. A rule of thumb is if it's raw and unfrozen then you can freeze it, if you then cook it you can freeze it again. If you've defrosted and reheated a previously cooked frozen then re-heated food don't refreeze. i hope that makes sense!
