The beauty of this recipe is that you can do either one. I prefer the no-boil lasagna noodles because they save time and effort. Be sure to check the package to make sure. To use pre-boil sheets simply cook them according to the package instructions and cool them in a bowl of cold water to stop the cooking process. Layer and bake the lasagna as usual. *Pro tip- When using the no boil sheets make sure that your sauce has a little extra liquid to be able to cook the noodles.
