Preheat your oven to 350°F. Wrap a rimmed baking sheet with aluminum foil and top with a wire rack.
In a large bowl add the maple syrup and the bacon to the bowl and toss gently with your hands. Make sure that all of the slices are evenly coated. Place the bacon in a single layer onto the wire rack.
Bake in the center of the oven for about 20 minutes. The bacon will be a bit brown, but will most likely need to bake for another 10-15 minutes. It should look slightly dark and crispy. Remove from the oven and cool for 5 minutes on the rack. Cut into pieces.
