Cheesy Beef Lasagna

Cook the lasagna noodles according to package instructions. Drain and set aside.
Make the Beef Filling:

In a large skillet, heat olive oil over medium heat. Add the minced garlic and cook for 1 minute.
Add the ground beef and cook until browned, breaking it up with a spoon. Stir in crushed tomatoes, tomato paste, basil, oregano, salt, and pepper. Let it simmer for 10 minutes, stirring occasionally. Set aside.
Make the Béchamel Sauce:

In a saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes. Gradually add the milk, whisking constantly to avoid lumps.
Simmer until the sauce thickens, then season with salt, pepper, and a pinch of nutmeg (if using).
Assemble the Lasagna:

Preheat your oven to 375°F (190°C). In a 9×13-inch baking dish, spread a thin layer of the beef mixture on the bottom.
Add a layer of noodles, followed by a portion of the béchamel sauce, then ricotta cheese, mozzarella cheese, and Parmesan.
Repeat the layers until the dish is full, finishing with a top layer of noodles and béchamel sauce. Sprinkle with extra mozzarella and Parmesan cheese.
Bake:

Cover with aluminum foil and bake for 25 minutes. Then, remove the foil and bake for an additional 15-20 minutes until the top is golden and bubbly.
