Preheat the oven to 350 F. Place a wire cooling rack inside of a rimmed baking sheet.
Lay the bacon in a single layer on the wire rack; the pieces can touch, but they shouldn't overlap.
Bake for 12 to 20 minutes, depending on thickness and desired crispness. Transfer the cooked bacon to a paper towel-lined plate or surface to soak up excess oil and cool slightly.
Notes
The amount of cooking time definitely depends on how thick your bacon is. This works with bacon of any thickness, but you do have to keep an eye on things. Thin bacon will take about 12 minutes in a 350-degree oven, and thick bacon about 20 minutes at 350. It also depends on how crispy you are looking for your bacon to be.
You can line the baking sheet with foil first if you want to make cleanup a bit easier, though I find that it requires a very concerted effort to seal the foil around the pan so that no bacon grease seeps under. If you have the patience, it will pay off later.
