Preheat oven to 350 degrees. In a medium skillet brown the ground beef. Drain and add the spaghetti sauce. Set aside.
Cook the spaghetti according to the package directions. Drain and place in a large mixing bowl.
Add cream cheese, italian seasoning, and garlic. Stir until the cream cheese has melted and the noodles are coated.
Place a small amount of sauce in the bottom of a greased 9x13 inch dish. Put spaghetti on top of the sauce and top with remaining sauce. Sprinkle parmesan cheese on top.
Bake for 30 minutes until bubbly and heated through.
