FROM THAWED: Prepare the lasagna through step 8. Wrap the unbaked lasagna tightly in plastic wrap in an oven-safe baking dish and freeze for up to 2 months. Thaw completely overnight in the refrigerator, then bake for approximately 1 hour and 10-15 minutes at 375 degrees Fahrenheit until fully heated through. FROM FROZEN: Assemble, freeze, and bake directly from frozen at 375 degrees Fahrenheit for 1 hour and 20-30 minutes until heated through, hot and bubbly. You can also prepare the lasagna through step 8, cover in foil and place in the refrigerator for the following day. Reheat the same way as above as it'll be far colder than if you prepared straight to baking.
