Boil a large pot of water and add the pasta with a teaspoon of salt.

Drain the pasta and set aside.

Meanwhile add the olive oil and the butter in a large saucepan. Melt the butter over medium heat. Once melted add the flour and cook while whisking for about 3 minutes.

Take the pan off the heat temporarily and gradually stir in one-third of the milk. Return to the heat and simmer, stirring, until all the milk is absorbed.

Repeat this process, stirring all the time, allowing the sauce to become thick and shiny before adding more milk.

When all the milk is added bring to the boil. Simmer gently for 8-10 minutes and season with all the spices listed in the ingredients.

When the milk has gained some texture close the heat and add half of the grated cheese. Mix until well combined and melted.

Pour the pasta into a baking dish and on top pour the milky mixture. Mix well until well blended.

Sprinkle the remaining cheese and place in the middle rack of the already heated oven. Cook until crispy and golden on the top, about 20 minutes. Serve warm.
