<human>:  How do I make the best lasagna?
<bot>: To make the best lasagna, start by pre-cooking the noodles according to the package instructions. Next, make a white sauce with butter, flour, and milk, and season it with salt, pepper, and nutmeg. Layer the lasagna in a greased baking dish, beginning with a layer of noodles, a layer of the white sauce, then a layer of desired fillings such as cooked ground beef, mozzarella cheese, Parmesan cheese, and ricotta or cottage cheese. Repeat the layering process until all ingredients are used, finishing with a top layer of mozzarella cheese. Lastly, bake the lasagna at 350°F for about 40 minutes or until the cheese is melted and lightly golden brown. Enjoy!
