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.

Size Matters. How long chilled lasagna takes to cook depends mostly on the size of the pan, as well as the oven temperature. Preheat the oven to 400 degrees Fahrenheit. Bake an 8-inch square pan of lasagna for 40 to 50 minutes. A refrigerated lasagna in a 9- by 13-inch baking pan will need between 55 and 70 minutes, while a jumbo-sized pan needs 70 to 85 minutes.
