I just made a wild mushroom lasagna for a dinner party I'm having soon, and once it was complete and in the pan I realized I had forgotten to grease it. The bottom and sides are coated with a bechamel-type sauce.
Is this terrible news? Is there any way to lessen the chance of sticking, such as cooking at a lower heat or submerging the bottom in a water bath?
Any help or reassurance greatly appreciated!
