In a small bowl, beat the egg. Add the butter and the warm pasta. Toss until butter is melted. Add parmesan cheese, basil, and a little salt and pepper and toss everything gently to combine. Empty pasta mixture into prepared pie pan and pat firmly into pan.
Spread cottage cheese evenly over the top of the pasta. Spoon your favorite spaghetti sauce over top and smooth into an even layer.
