You may prepare lasagne up to 24 hours in advance without baking it.  Prepare and store the lasagne in the refrigerator at or below 40 degrees F.  Since the lasagne will be cold it will require a longer baking time, approximately 60 minutes at 375 degrees F.  If your recipe calls for egg, the cooking time will be approximately 1 hour and 10 – 1 hour and 20 minutes.  Make sure the internal temperature reaches at least 160 degrees F.
For best results, we recommend that you do not bake the lasagna before freezing. You may assemble the lasagna in a freezer safe/oven safe container, cover tightly and freeze.  When you are ready to bake the lasagna, defrost in the refrigerator for 24 hours. Bake at 375 degrees F for approximately 1 hour 10 minutes.  If your recipe calls for egg, the baking time will be approximately 1 1/2 - 2 hours.  Make sure the internal temperature reaches 160 degrees F.
