A packaging system for uncooked edible goods including a sheet of a baking substrate and a box for transporting the sheet and goods. The sheet has a first length and first width and the box has one or both of a second length and second width, where the second length is smaller than the first length and the second width is smaller than the first width. One or more folds in the sheet enable the sheet to be folded in order to fit into the smaller-dimensioned box. Uncooked edible goods are placed on a goods-receiving surface of the folded sheet. The box is delivered to a retailer. The folded sheet is removed from the box, is placed onto a baking pan, and is unfolded while the edible goods remain thereon. The goods are moved apart from each other, the pan is placed into an oven, and the goods are cooked.
