It seems like every nonna has a secret to their lasagna — one that no one would ever know unless they stood beside her in the kitchen and watched her every move.

In every lasagna, thought is given to seasoning every layer of the sauce, ricotta mixture, or béchamel. There is one layer I had never considered seasoning: the shredded cheese on top.
