To bake the lasagna:
Preheat oven to 400 degrees F. If previously refrigerated, be sure to allow lasagna to come to room temperature before cooking, otherwise your cook time will be extended. Cook, covered, until heated through, 40-60 minutes. You may remove the foil for the last 5-10 minutes of cooking time to help melt the cheese and release some of the moisture. Allow lasagna to rest for 15-20 minutes before serving to absorb any remaining liquid.
