Preheat your oven to 350°F (175°C).

In a large pot, bring salted water to a boil, then add the spaghetti. Cook until al dente, about 8-10 minutes. Toss in a teaspoon of olive oil once drained.

In a skillet, brown your ground meat for about 6-8 minutes. Stir in the marinara sauce and let it simmer for 8-10 minutes.

In a large mixing bowl, combine the cooked spaghetti with the cream cheese until well coated.

In a greased baking dish, layer half of the spaghetti mixture, then the meat sauce, and top with remaining spaghetti.

Sprinkle shredded mozzarella cheese over the top.

Bake uncovered for 25-30 minutes until the top is bubbly and golden.

Let the casserole rest for 5-10 minutes before serving.
