Baked Four-Cheese Pasta with Tomatoes and Basil

From America's Test Kitchen

We love macaroni and cheese (who doesn’t?), but sometimes we want a more adult version than the typical neon orange mac and cheese. Enter the classic Italian iteration of macaroni and cheese, pasta ai quattro formaggi, made with four cheeses and heavy cream. We set out to make a four-cheese creamy pasta casserole with great flavor, properly cooked pasta, and a crisp bread-crumb topping.

The cheese was first up for consideration; for the best flavor and texture, we used Italian fontina, Gorgonzola, Pecorino Romano, and Parmesan cheeses. Heating the cheese and cream together made a greasy, curdled mess, so instead we built a basic white sauce (a béchamel) by cooking butter with flour and then adding cream. Combining the hot sauce and pasta with the cheese—and not cooking the cheese in the sauce—preserved the fresh flavor of the different cheeses. Knowing the pasta would spend some time in the oven, we drained it before it was al dente so it wouldn’t turn to mush when baked. Topped with bread crumbs and more Parmesan, and baked briefly in a very hot oven, our pasta dinner was silky smooth and rich but not heavy—a grown-up, sophisticated version of macaroni and cheese with Italian flavors.
