Have just put BBC Good Food's roast veg lasagne in the oven. They said use fresh lasagne and bake 45 mins; I can't get fresh lasagne here, so used normal. On the packet it says pre-cook 4 mins (which I did), then bake the lasagne for 20 mins.
Does this mean my lasagne only needs 20 mins too? Is the BBC GF's timing because of the fresh lasagne sheets??
