Preheat oven to 400F
Line your baking sheet with foil, letting the foil extend up. This will make cleanup easier later
Arrange bacon in a single layer on the foil. Do not overlap the slices or they will stick together when they cook. Use 2 baking sheets if you need to - you can cook both at the same time!
Place baking sheets in the oven
After 12 minutes, remove baking sheets and pour off some of the bacon grease (you can also use a paper towel to soak some of it up).
Return baking sheets to oven
After another 5 minutes, check the bacon for doneness. Continue to bake until bacon reaches desired crispiness.
