I made 75 latkes this weekend for Thanksgivukkah and put them in the freezer. I know they should be reheated in a single layer but even with 2 ovens that's not realistic. Can I put them in baking sheets in a single layer and put the baking sheets on top of each other?
They really only take a few minutes to reheat. If you really are strapped for space/time, you might consider taking a flat baking rack and doing a double deck arrangement, with half on top of the rack, and half on the baking pan. You need to leave as much air circulation as possible, so don't pile them on top of each other.
