Cook the spaghetti according to the package instructions until al dente. Drain and set aside.

Heat a skillet over medium heat and brown the ground beef for 5-7 minutes, breaking it up as it cooks. Drain the excess fat.

Stir in the marinara sauce and Italian seasoning, and let it simmer on low heat for about 10 minutes.

In a large mixing bowl, combine the cooked spaghetti with the cream cheese until smooth and creamy.

In a greased baking dish, layer half of the spaghetti mixture, followed by half of the meat sauce and half of the mozzarella. Repeat the layering.

Preheat the oven to 350°F (175°C) and bake uncovered for 25-30 minutes, until golden and bubbly.
