Cover the bottom of a 13 x 9-inch (33 x 23 cm) baking dish with ½ cup (125 ml) of the hot meat sauce. Cover with a layer of noodles, 2 cups (500 ml) of the meat sauce and ⅔ cup (150 ml) of the béchamel. Sprinkle with ⅔ cup (65 g) of the grated cheese. Repeat layering in the remaining noodles, meat sauce and béchamel, finishing off with the remaining grated cheese (you can freeze the lasagna at this stage, without the cheese, if desired). Place the dish on a baking sheet.
