To start, cook the lasagna noodles according to the package instructions if you’re not using oven-ready noodles. Drain and set aside. In a large skillet, brown the ground beef or Italian sausage over medium heat, breaking it into crumbles as it cooks. Drain any excess grease and stir in the marinara sauce, allowing it to simmer for a few minutes to develop the flavors. Season with garlic, Italian seasoning, salt, and black pepper for extra depth.

In a separate mixing bowl, combine the ricotta cheese, cream cheese, sour cream, egg, and a portion of the Parmesan cheese. Mix until smooth and well combined. This creamy mixture is what gives million dollar lasagna its signature taste and texture.

Now, it’s time to assemble the lasagna. Spread a thin layer of the meat sauce on the bottom of a baking dish to prevent sticking. Add a layer of lasagna noodles, followed by a generous spread of the ricotta mixture. Sprinkle some mozzarella cheese over the top before adding another layer of meat sauce. Repeat the layering process until all the ingredients are used, finishing with a final layer of noodles, meat sauce, and a generous topping of mozzarella and Parmesan cheese.

Cover the baking dish with aluminum foil and bake in a preheated oven at 375°F (190°C) for about 30 minutes. Remove the foil and continue baking for another 10-15 minutes, or until the cheese is golden brown and bubbly. Let the lasagna rest for at least 10 minutes before slicing to ensure the layers hold together.
