Preheat oven to 400 ℉.

Line a sheet pan with aluminum foil then add a baking rack or cooling rack and arrange bacon slices on the rack.

Place in oven and bake until desired crispiness.

Thicker slices bake between 25-30 minutes.

When the bacon reaches the desired level of crispy you enjoy, remove it from the oven. Allow to cook 5 minutes and serve.
