Cook macaroni in a large pan of boiling water until al-dente (just tender), drain. Blend cornflour with a small amount of the milk in a medium saucepan until smooth, then stir in remaining milk. Place pan over heat and stir constantly until sauce boils and thickens. Combine sauce, macaroni, ham, parsley and 1 cup of the grated cheese in a large bowl.

Divide mixture into 6 x 175ml capacity, greased ramekin dishes and sprinkle with the remaining grated cheese. Place dishes on an oven tray, and bake in a 180°C (160°C fan forced) preheated oven for 30-35 minutes or until tops are golden.
