Think making grilled cheese sandwiches for a crowd involves transforming into a short order cook? My pans fit two or three sandwiches, max, and require hovering over them to avoid any burns. No longer! Check out this smart tip involving two baking sheets. This is one of those "why didn't I think of that?" moments. The key to this process, as explained by Cook's Country, is to cook the sandwiches between two preheated baking sheets. Throw the baking sheets in the oven until hot, place the buttered and assembled sandwiches on one tray and cover with the second tray, rim side up. Bake until golden and gooey. No flipping, hovering or industrial size griddles required. Genius!
