When you refer to “lasagna sheets”, are these the same as the wide dry lasagna noodles with frilly edges commonly found in Canada/US? Or is this a dried version of the very wide fancy fresh sheets found in some shops? I’d love to try this but don’t want to have done all this work just to mess up the pasta part!
Nigella's Lasagne Of Love (from COOK, EAT, REPEAT) is a family favourite that Nigella cooks for many occasions. It is made with dried and not fresh lasagne sheets (noodles). Nigella has adapted her recipe to make the meat sauce slightly "saucier" than normal, to allow for the amount of liquid that the dried pasta sheets will soak up. We would actually avoid using fresh pasta sheets (either home made or store bought), as the lasagne could end up being too liquid inside.
In the US, dried lasagne sheets can be flat rectangles, wavy sheets or flat sheets that are frilly at the edges. Any of these will be suitable for the lasagne. Some packages of dried sheets are labelled as "no boil" or "oven ready" and these can also be used as well as the regular, dried sheets.
