ever dreamt of using straight out of the box. Well, go ahead and dream, they're straight out of the box now! I have never cooked a better lasagne. I hope I've convinced you -- your family will be shocked and amazed, as will you. The noodles could not be more forgiving, they'll keep sucking it up as long as you need them to. Now how many humans can you say that about? I rest my case. Now the construction begins. 1. Spread a thin layer of meat sauce to cover the bottom of the slow cooker. 2. Layer of noodles, break as necessary. 3. Layer of cheese mixture. 4. Layer of noodles, break as necessary. 5.  Layer of meat sauce, cover with grated cheese. 6. Layer of noodles. Another layer of cheese mixture, followed by more noodles. 7. Finish with a layer of meat sauce and cover with the rest of the grated cheese. Cover and turn on high for 3-4 hours or low for 5-6 hours. Insert a knife and if it goes in like butter, it's done. Turn off the slow cooker and let it firm up. If you dig in straight away, it will be a little loose, but it will be just as tasty.
