Over the past few years, no-boil (also called oven-ready) lasagna noodles have become a permanent fixture on supermarket shelves. Much like “instant rice,” no-boil noodles are precooked at the factory. The extruded noodles are run through a water bath and then dehydrated mechanically. During baking, the moisture from the sauce softens, or rehydrates, the noodles, especially when the pan is covered as the lasagna bakes. For both our lasagna and manicotti recipes, we prefer Barilla no-boil noodles for their delicate texture, which resembles that of fresh pasta.
