Best Lasagna Recipe

1. Heat large skillet over medium high heat. Add oil. Saute onion for 4-5 minutes. Add ground beef, garlic, salt and pepper and cook until browned. Drain grease.
2. Stir in marinara sauce. Let simmer on low heat.
3. In a medium saucepan, bring the cream and milk to a simmer over medium heat. Reduce the heat to low. Add 1 1/2 cup of Parmesan cheese and whisk until melted and the sauce is smooth. Remove the pan from the heat and stir in the basil and garlic. Season with salt and pepper.
4. Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until tender, stirring occasionally, about 8 to 10 minutes. Drain and set aside. You can also use oven-ready lasagna noodles.

Assemble the Lasagna:

1. Preheat the oven to 375°. Spray a 9-by-13-inch glass baking dish with cooking spray. 
2. Spread 1 cup of the marinara sauce in the bottom of the prepared baking dish. Lay 3 noodles over the marinara. Spread 1/3 of the bechamel cream filling mixture evenly over the noodles. Sprinkle with bolognese sauce. Repeat with the remaining noodles, bechamel cream filling, and mozzarella cheese making 3 layers of filling and ending with pasta. Spoon the remaining marinara sauce on top and sprinkle with remaining 1/2 cup of Parmesan cheese and Mozzarella cheese. Drizzle with olive oil and cover with foil. 
3. Bake covered for 25 minutes until the lasagna is heated through. Remove foil and let the cheese melt and bubble -- about 5-10 minutes longer. Allow to cool for 15-20 minutes before serving. Cut into squares and serve.
