Prepare as directed, but do not bake. Wrap, label, and freeze. Freeze cheese for topping separately. To serve, thaw in the refrigerator overnight. Bake, covered, in 350 degree F oven for 1 hour. Sprinkle with reserved cheese. Bake, uncovered, for 15 minutes more or until the cheese is golden and the lasagna is heated through. Let stand about 15 minutes before serving.
