Place a baking rack on a sheet pan and arrange the bacon in 1 layer on the baking rack. Bake for 15 to 20 minutes, until the bacon begins to brown. Remove the pan carefully from the oven; there will be hot grease in the pan! Brush the bacon slices with maple syrup and bake for another 3 to 5 minutes, until the bacon is a warm golden brown. Transfer the bacon to a plate lined with paper towels and serve warm.
