Place parchment paper on a rimmed baking sheet. Lay as many slices of bacon on the paper as you would like. They can be touching, just not overlapping.
Place the bacon in the oven and bake for 12 minutes. Rotate the pan for even cooking then bake for 10 minutes more. Watch carefully during the last 2 minutes to prevent burning. It's done when dark and crispy.
Remove the pan form the oven and set on a cooling rack. Transfer the bacon to a paper towel-lined plate to drain.
Simply slide the parchment paper into the trash when it has cooled. Clean up is done!
One Last Thing
Thick-cut bacon is best for this technique. You can find it packaged, but you can also get it from the butcher at your local supermarket!
