Best Cooking Oils: No Boil Lasagna Noodles

No Boil Lasagna Noodles

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. Most no-boil noodles are rippled, and the accordion-like pleats relax as the pasta rehydrates in the oven, allowing the noodles to elongate.No-boil lasagna noodles come in two shapes. The most common is a rectangle measuring 7 inches long and 3 1/2 inches wide; we found three brands in this shape. One other brand came in 7-inch squares. We made lasagnas with all four brands to see how they would compare. The two brands with noodles that are both thin and rippled worked well. Two squares of the 7-inch noodles butted very closely together fit into a 9 by 13-inch pan, but when baked the noodles expanded and the edges jumped out of the pan and became unpleasantly dry and tough.
