Boil water in a large pot. Add a pinch of salt. Cook the lasagna noodles until soft but firm. Drain them and set aside. Place them flat to prevent sticking.

Heat olive oil in a pan over medium heat. Add chopped onion and cook until soft. Add garlic and cook briefly. Add ground beef and cook until browned. Stir well.

Pour in the tomato sauce. Add salt, pepper, oregano and basil. Mix everything well. Let it simmer for about 10 minutes. This builds a rich and tasty sauce.

In a bowl, add ricotta cheese and one egg. Mix until smooth. Add a little salt and pepper. This mixture gives the lasagna a creamy texture.

Set your oven to 180°C (350°F). This ensures even cooking. While the oven heats, you can start layering the lasagna.

Spread a thin layer of meat sauce in the baking dish. Place noodles on top. Add ricotta mixture, then mozzarella cheese. Repeat the layers carefully.

End with a layer of meat sauce. Sprinkle mozzarella and parmesan cheese on top. This creates a golden and bubbly crust.

Cover the dish with foil. Bake for 30 minutes. Then remove the foil and bake for another 15 minutes. The top should be golden and melted.

Take the lasagna out of the oven. Let it rest for 10 minutes before cutting. This helps the layers hold together.
