Manicotti are tubes of pasta stuffed with Italian cheeses and baked in a simple tomato sauce, similar to a meatless lasagna. Those who have made manicotti before and have been scarred by the experience may want to run in the opposite direction from this recipe. But fear not: thanks to no-boil lasagna noodles, we have a dramatically streamlined manicotti recipe that does away with precooking the pasta and the fussy task of stuffing each pasta tube with filling. Learning how to make stuffed manicotti with our recipe requires a fraction of the work of a traditional manicotti preparation yet tastes every bit as good.
