The Number Of Layers You Need For Perfectly Balanced Lasagna Every Time - Tasting Table
Briefly

To achieve a well-balanced and pleasing lasagna, aim for four to five layers. More than that can lead to an overly dense and unmanageable dish.
The thickness of your pasta sheets can affect the lasagna’s final outcome significantly, impacting moisture retention and overall structural integrity.
Thicker sheets work better for heavier fillings like bolognese, as they absorb moisture well, while lighter fillings can be paired with thinner sheets.
Cooking times will lengthen with thicker pasta sheets, so you'll need to find a good balance between thickness, filling, and cooking duration.
