The concept of sneaking veggies into a pasta dinner has long been marketed at parents of finicky children, but who are we kidding? Adults can need help packing vegetables into their meals, too. Broccoli is the base of this vibrant emerald sauce, which is silky smooth thanks to pasta water, which adds starchiness and body. The result is gorgeously green and richly delicious. Prep tip: if your broccoli has a long stem, use a vegetable peeler to take off the rough, outer layer. Since this sauce freezes well, you could also make a double batch and freeze half for later.
