How long to bake lasagne at lower temperature? My recipe states that I need to bake my fish lasagne for 40 min at 180 degrees Celsius. I will go out and want the food to be ready when I return but will not be back within 40 minutes. Is there a way how I can extend the cooking time at lower temp without drying the lasagne out?
Yes. Use a thermometer. Your lasagna will be done at an internal temperature of 165F (74C). Just lower the baking temp appropriately. I can't know the time and oven temperature that will actually work for you, because you didn't present them, but I hope this helps.
