Delicious Beef Lasagna

Prepare the Beef Ragù:

1. In a large skillet, heat olive oil over medium heat.
2. Add chopped onions and cook until translucent.
3. Stir in minced garlic and cook for an additional minute.
4. Add ground beef and cook until browned, breaking it up with a spatula.
5. Pour in crushed tomatoes and tomato sauce, then add basil, oregano, salt, and black pepper.
6. Simmer the ragù for about 20-25 minutes, allowing the flavors to meld together. Set aside.

Make the Béchamel Sauce:

1. In a saucepan, melt butter over medium heat.
2. Add flour and whisk constantly for about 2 minutes to form a roux.
3. Gradually pour in milk, whisking continuously to avoid lumps.
4. Cook the sauce until it thickens and coats the back of a spoon.
5. Season with ground nutmeg, salt, and pepper. Remove from heat.

Assemble the Lasagna:

1. Preheat your oven to 375°F (190°C).
2. Spread a thin layer of beef ragù in the bottom of a 9x13-inch baking dish.
3. Place 3 lasagna noodles over the ragù layer.
4. Spread 1/3 of the remaining beef ragù over the noodles.
5. Drizzle 1/4 of the béchamel sauce over the beef ragù.
6. Sprinkle 1/3 of the shredded mozzarella cheese on top.
7. Repeat the layers two more times, ending with a layer of noodles, béchamel sauce, mozzarella, and grated Parmesan cheese on top.

Bake and Serve:

1. Cover the baking dish with aluminum foil and bake for 25 minutes.
2. Remove the foil and bake for an additional 20-25 minutes, until the top is golden brown and bubbly.
3. Let the lasagna rest for about 15 minutes before slicing and serving.
4. Garnish with fresh basil or parsley if desired.
