<human>:  I'm looking for a good recipe to make lasagna.
<bot>: One of my favorite lasagna recipes is to start by preheating the oven to 375°F (190°C). Then, prepare the sauce by sautéing onion, garlic, and ground beef or turkey until the beef is cooked through and the onion is soft. Next, mix together canned crushed tomatoes, tomato paste, Italian herbs, and some red pepper flakes. Spread a thin layer of the sauce on the bottom of the baking dish then layer the lasagna noodles on top. After that, add a layer of the remaining sauce, followed by more noodles and a layer of ricotta cheese. On top of that, add a layer of mozzarella and any additional ingredients you'd like, like mushrooms or spinach. Finally, top the lasagna with the remaining sauce and cheese. Put the dish in the oven and bake for 40 to 45 minutes, or until the cheese on top is golden brown and bubbly. Enjoy!
