Preheat your oven to 350°F (175°C).
Boil the spaghetti noodles until they are al dente (firm). Drain and set them aside until you’re ready to assemble the casserole.
In a mixing bowl, combine the cream cheese, sour cream, and cottage cheese until well blended.
In a separate pan, brown the ground beef, and when done, drain it well. Combine the cooked beef with the spaghetti sauce.
Place a few slices of butter into a 9×13-inch baking dish, then pour half of the cooked spaghetti noodles on top.
Spread the cream cheese mixture evenly over the noodles.
Add the remaining spaghetti noodles on top of the cream cheese mixture and place a few more slices of butter on them.
Pour the spaghetti and meat sauce over the noodles.
Place the casserole in the preheated oven and bake for 30 minutes.
After 30 minutes, sprinkle your desired amount of grated cheddar cheese on top and return the casserole to the oven for an additional 15 minutes to allow the cheese to melt.
Once the cheese is bubbly and golden, it’s time to dig in and enjoy!
