Remove the plastic wrap but leave on the foil and transfer directly to a 350°F oven. Bake covered for 40 minutes, then remove from the oven. While the enchiladas bake, defrost the sauce. Then when they come out of the oven after 40, add the enchilada sauce on top of them. Crank the heat up to 375°F. Bake the enchiladas and sauce uncovered for an additional 15 minutes until cooked through.
