Cavolfiore à la milanaise

Cavolfiore alla milanese is a traditional dish originating from Milan. It's made with a combination of cauliflower, butter, onions, grated cheese, and parsley. The cauliflower is trimmed, washed, drained, and covered with boiling salted water until barely tender. Once drained, the cauliflower is divided into flowerets, and the flowerets are then cooked in a mixture of butter and onions. The dish is sprinkled with Parmigiano-Reggiano cheese, the remaining melted butter, and parsley, and it's then baked in a hot oven until golden and bubbly. Cavolfiore alla milanese is always served hot out of the pan.
