For optimal crispness and even cooking, ensure bacon slices are in a single layer without overcrowding the baking sheet; use a second sheet if necessary. While parchment paper aids cleanup, a wire rack placed over the rimmed sheet allows fat to drip away, promoting superior crispness and preventing the bacon from frying in its own rendered fat. Monitor closely during the final baking stage, as oven temperatures can vary, and bacon can go from perfectly crispy to burnt quickly. For seasoned bacon, a light sprinkle of black pepper, or even a touch of brown sugar for candied bacon, can be added before baking.
