<human>:  How do I make traditional Italian lasagna?
<bot>: To make traditional Italian lasagna, you will need lasagna noodles, a tomato-based sauce, ricotta or mozzarella cheese, and any other desired toppings like ground beef, vegetables, or herbs. Start by preheating your oven to 375 degrees Fahrenheit. Then, cover the bottom of a 9x13 inch baking dish with a layer of the tomato-based sauce. Layer your lasagna noodles over the sauce, then spread a layer of ricotta or mozzarella over the noodles. Add any other desired toppings, then top with a final layer of cheese. Cover with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 15 minutes. Allow to cool before serving.
