Hi Dean! Yes, you can keep the boards in the freezer right before serving so that your cheese stays cool. Some people will store their small slate cheeseboards in the freezer but we never have space! If your plates are too long, they may not fit but you can make room. You can just pop them in on top of each other or wrap them if you don’t want them touching other items in the freezer… especially if you have raw meat. Hope this helps!
