We proceed to the assembly: at the bottom of the mold, I put 3 sheets of lasagna overlapping, then a layer of minced meat, bechamel sauce, a layer of cheese. Repeat everything twice, the top layer should be Bechamel sauce, sprinkled with cheese. Do not leave the edges of the lasagna empty if there is most likely no Bechamel sauce on them. they stay dry. Bake in the oven for about 45 minutes.
