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.

1 Refrigerate until use. 2  Use or freeze within 3 days of purchase. 3  Bake in a 375Â° preheated oven, uncovered, for 45-60 minutes (note: it may take longer to bake if the lasagna is cold when you put it in the oven, bring to room temperature before baking for best results). The lasagna is done when, the top begins to brown lightly, the lasagna liquids begin to bubble around the sides of the tray, and the internal temperature reaches 165Â°. 2  If the lasagna begins to brown too quickly, cover loosely with a sheet of aluminum foil until heated through.
