Bring a large saucepan of lightly salted water to a boil. Add lasagne pasta and cook for 8 to 10 minutes or until al dente; drain and rinse with cold water.
Line the bottom of a casserole dish with pasta and spread on 1/4 cup of the spaghetti sauce. Add another layer of noodles and begin alternating layers of cheeses, noodles and sauce beginning with the cottage cheese. Make sure you leave enough spaghetti sauce to cover the top to prevent hardening of the top layer of noodles. Finish with a sprinkle of Parmesan.
Bake in a preheated oven until cheese is well melted and filling is heated through; about 20 or 25 minutes.
