This recipe comes from an America's Test Kitchen cookbook entitled The Best Make-Ahead Recipe. Everything I've made from this cookbook has been superb and this is my new favorite! The best part about this recipe is that it uses Barilla's No Boil Lasagna Noodles. After making this lasagna I will never use another kind of noodle! The noodles mimic fresh pasta because they turn out delicate, not chewy like other no-boil noodles I've tried. Make sure to use good quality canned tomatoes and don't be alarmed about the sauce tasting too tomato-y and sharp because the taste mellows dramatically in the final dish. The recipe calls for meatloaf mix but if you can't find it (or in my experience, aren't willing to pay the high price) you can substitute lean ground beef, pork, italian sausage, or any combination thereof. Whole milk ricotta cheese and mozzarella give the best results if you are freezing this dish to serve later but if you are baking this immediately then skim or part-skim ingredients can be substituted without any loss in flavor.
