Boil water in a large pot. Add salt and noodles. Cook until soft but firm. Drain and lay flat on a clean surface. This keeps them from sticking together while you prepare the layers.

Heat olive oil in a pan. Add onion and cook until soft. Add garlic and cook briefly. Add ground beef and cook until browned. Pour in marinara sauce. Add salt, pepper, oregano, and basil. Simmer for 10 minutes.

In a bowl, add ricotta cheese, egg, and half of the parmesan. Mix well until smooth. This mixture gives a creamy texture. It also helps bind the layers nicely when baking.

Set your oven to 180°C (350°F). Let it heat fully before placing the lasagna inside. This ensures even cooking and perfect melting of the cheese layers.

Spread a thin layer of meat sauce at the bottom of the baking dish. Add noodles on top. Spread ricotta mixture. Add meat sauce again. Sprinkle mozzarella. Repeat layers carefully.

Add final noodles on top. Cover with remaining sauce. Sprinkle mozzarella and parmesan evenly. This top layer becomes golden and bubbly after baking.

Cover with foil and bake for 30 minutes. Remove foil and bake for another 15 minutes. The cheese should melt and turn lightly golden on top.

Remove from oven and let it rest for 10–15 minutes. This step is very important. It helps the layers set properly and makes slicing much easier.
