Put the water for the macaroni to come to a boil in a container.
Once it does, add 2 tbsp oil and 1/2 tbsp salt. Pour the macaroni into the water.
Leave them to boil but not completely.
Pour the semi-boiled macaroni in the tray.
Crumble the feta cheese, add it on top, as well as the butter, chopped into pieces, and the cream. Stir well.
Grate the cheese on top and bake in a preheated 356°F (180 °C) oven.
