<human>:  How do I make a delicious lasagna?
<bot>: To make a delicious lasagna, start by preheating your oven to 350 degrees Fahrenheit. Grease a 9x13 inch baking dish with butter or olive oil. Place a layer of uncooked lasagna noodles on the bottom, then spread a layer of your favorite marinara sauce over the noodles. Add a layer of ricotta cheese, then sprinkle with mozzarella cheese, Parmesan cheese, and your favorite seasonings. Top with another layer of lasagna noodles, then repeat the layering process with the remainder of the ingredients. Bake in preheated oven for about 45 minutes, or until the cheese is golden and bubbly. Allow to cool before serving, and enjoy!
