Prepare the Bolognese Meat Sauce:

• In a large pot over medium heat, add the ground beef and ground pork. Cook until browned and fully cooked. Drain any excess fat.
• Add the chopped onion and minced garlic to the pot and cook until softened and fragrant, about 3-4 minutes.
• Stir in the tomato paste and cook for another 2 minutes.
• Add the crushed tomatoes, red wine, dried basil, oregano, salt, and pepper. Stir well to combine.
• Bring the sauce to a simmer and reduce the heat to low. Let it cook uncovered for 30-40 minutes, stirring occasionally, until it thickens.

Prepare the Béchamel Sauce:

• While the Bolognese is simmering, melt the butter in a medium saucepan over medium heat.
• Whisk in the flour and cook for about 2 minutes until the mixture is lightly golden and fragrant.
• Gradually whisk in the milk, a little at a time, to ensure no lumps form. Continue to whisk until the mixture thickens (around 5-7 minutes).
• Stir in the ground nutmeg (optional) and season with a pinch of salt. Remove the béchamel sauce from the heat.

Prepare the Lasagna Noodles:

• If using uncooked lasagna noodles, follow the package instructions to ensure they’re soft enough for layering. Alternatively, pre-cooked noodles can be used directly.

Assemble the Lasagna:

• Preheat your oven to 375°F (190°C).
• In a 9×13-inch baking dish, spread a thin layer of Bolognese sauce over the bottom of the pan.
• Layer the noodles over the sauce, followed by a layer of béchamel, a layer of the Bolognese sauce, and a sprinkle of mozzarella and Parmesan. Repeat this layering process until all ingredients are used, finishing with a layer of béchamel topped with mozzarella and Parmesan.

Bake the Lasagna:

• Cover the lasagna with aluminum foil (to prevent it from drying out) and bake for 25-30 minutes.
• Remove the foil and bake for an additional 20-25 minutes, or until the cheese is melted, bubbly, and golden brown.

Rest the Lasagna:

• Once baked, remove the lasagna from the oven and let it sit for about 15 minutes. This will make it easier to slice and serve.

Serve and Enjoy:

• Slice into portions, garnish with fresh basil if desired, and serve warm. Pair it with a side of garlic bread or a fresh green salad for the full Italian experience.
