Spaghetti aglio e olio—or spaghetti with garlic and oil—is a classic Italian dish and one of the quickest, tastiest dinners you can make with a handful of staple ingredients. We top ours with garlicky toasted breadcrumbs mixed with fresh parsley, lemon zest and Parmesan. The crumbs bring a crispness that contrasts the al dente pasta as well as adds another layer of flavor. Be sure to use light, airy panko breadcrumbs, not fine dry breadcrumbs, which won’t add texture.
