followed by page numbers - but I have no idea what this term means. At first I thought it was a reference to a classical author (spurred on a little bit by the character of Ibid in a Discworld book), but I realise now that it must have some technical meaning for referencing sources.
The cooking time on frozen lasagna varies, depending on how thick the lasagna is and what kind of oven you have. A basic lasagna typically has approximately 4 layers of noodles, cheeses, and sauce.So, based on that figure, it would take approximately 1 hour at 350 F in a convection oven.he cooking time on frozen lasagna varies, depending on how thick the lasagna is and what kind of oven you have.

Cover the dish with foil. Place the baking dish on a baking sheet to catch any sauce that bubbles over. Bake frozen lasagna for approximately 1 1/2 hours. Take the foil off the baking dish and bake for another 30 minutes or until the top is lightly browned and bubbling. Use potholders or oven mitts to remove the lasagna from the oven. Let it sit for 10 to 15 minutes before cutting it into pieces and serving.
