   Étape 1. Prepare the Bolognese sauce

   30 min

   Heat olive oil in a large pan over medium heat. Add finely chopped onion and garlic, sauté until softened. Add ground beef and cook until browned, breaking it up with a spoon. Stir in tomato paste, canned tomatoes, and beef stock. Season with salt and pepper. Simmer for 30 minutes until the sauce is rich and thickened.

   Étape 2. Make the béchamel sauce

   7 min

   In a saucepan, melt butter over medium heat. Add flour and whisk constantly for 1-2 minutes to form a roux. Gradually pour in milk while whisking to prevent lumps. Continue whisking until the sauce thickens and coats the back of a spoon, about 5-7 minutes. Season lightly with salt.

   Keep whisking to avoid lumps in the béchamel.

   Étape 3. Assemble the lasagna

   Preheat oven to 180°C (350°F). In a baking dish, spread a thin layer of Bolognese sauce on the bottom. Lay down lasagna sheets, then add a layer of Bolognese, a layer of béchamel, and a sprinkle of mozzarella and parmesan. Repeat the layers until all ingredients are used, finishing with béchamel and a generous topping of cheese.

   Make sure the top layer is well covered with cheese for a golden crust.

   Étape 4. Bake the lasagna

   45 min

   Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for another 15-20 minutes until the top is golden and bubbling. Let rest for 10 minutes before serving.

   Letting it rest helps the layers set and makes it easier to slice.
