8. In a gratin dish (square or rectangular), spread a thin layer of the mushroom sauce. Layer the lasagna sheets, followed by the Parmesan béchamel sauce, the broccoli “semolina,” and the mushroom sauce. Repeat this layering process until all the ingredients are used, finishing with a layer of béchamel sauce on top. Sprinkle the remaining 50 g of grated Parmesan over the top.

9. Cover the dish with parchment paper (or aluminum foil) and bake it for 20 minutes.

10. Remove the parchment paper (or foil) and broil the lasagna for about 5 minutes to achieve a golden-brown crust.
