Yes, although all the ingredients are cooked. If possible, defrost in the refrigerator (apx 24 hours) before baking. If you must bake a lasagne from a frozen state, you will need to cover with tin foil and bake for about 2 hours. Then uncover and bake for a further 30 minutes. Check the temp with an insta-read thermometer to ensure it is hot in the middle before serving.
