*If you use fresh lasagna noodles, there is no need to cook them.
Generate ideas in advance: Boil the squash ahead of time and refrigerate until ready to bake. Boil the noodles ahead of time and refrigerate, making sure they are coated with a little olive oil.
Or make the whole pot in advance: Prepare the entire lasagna before baking, then refrigerate overnight. Increase the baking time as needed to ensure it warms through and the cheese doesn't brown.
Storage information: Refrigerate leftovers for up to 2 days. Or freeze them: The easiest way is to cut them into portions and freeze each in individual containers. To reheat, thaw the lasagna in the refrigerator, then place in a baking dish, cover with foil, and reheat at 400 degrees for about 15 minutes until heated through.
