Spoon squash filling in the middle of pasta square and fold over. Cut excess pasta with round dough cutter into half moon shape. Place on floured tray.
Boil agnolotti in salted water until tender, about 3 to 4 minutes. Drain and place on a platter. Add butter and sage leaves to a medium sized saute pan and place over medium-high heat. Cook butter and sage until butter is golden brown. Spoon butter and sage over agnolotti and sprinkle with flaked Parmesan.
