This is a great way to make spaghetti for a group!
Preheat your oven to 350◦. Boil the spaghetti until firm. Drain and set aside until ready to assemble. Combine the cream cheese, sour cream, and cottage cheese until well blended. Brown the hamburger and drain well. Combine the hamburger with spaghetti sauce.
Put a few slices of butter into a 9x13 pan then pour half of the spaghetti noodles on top. Spread the cream cheese mixture and on top of the noodles. Pour the rest of the noodles on top of the cream cheese mixture. Put a few more slices of butter on top of the noodles. Pour spaghetti and meat sauce on top of noodles.
Bake for 30 minutes. Then Top with grated cheese and return to the oven for 15 minutes to allow cheese to melt.
