First, preheat your oven to 350 F or 180 C degrees.
Cook the spaghetti to your liking and drain them in the colander.
In a skillet over medium heat, brown the ground beef for about 5 minutes.
Pour in the sauce and mix until combined.
Mix the cream cheese, cottage cheese and sour cream in a medium-sized bowl until well combined.
Spray your 13x8 inch casserole pan with cooking spray and spread half of the noodles.
Spread the cream cheese on top of the noodles, then add the second half of the noodles.
Top with ground beef and sauce, and bake for about 30 minutes.
Sprinkle some parmesan cheese on top and cook for additional 15 minutes.
Serve and enjoy.
