Breaded chicken milanese baked instead of fried, which is the same coating with none of the pan of oil.
The foil is what makes a baked milanese work. Fifteen minutes covered steams the chicken and keeps it moist, and twenty-five uncovered afterwards is what crisps the coating. Skip the foil and you get dry chicken under a hard crust; leave it on the whole time and the breadcrumbs never colour. Wipe the tray with the marinade oil rather than adding fresh. There is no pan of oil in this recipe and the coating browns from the small amount of fat underneath it, so a thin film is enough and more makes it greasy. Half an hour of marinating in olive oil, garlic and parsley is where the flavour comes from, and it is what separates this from plain breaded chicken. The recipe offers a way to skip it, and the result is noticeably plainer. The same 200 grams of breadcrumbs does both coatings: crumbs, egg, crumbs again. That double layer is what gives it enough thickness to crisp in an oven.
