Line a large baking sheet with aluminum foil (up the edges), and then lightly spray foil with non-stick baking spray.
Lay strips of uncooked bacon onto the foil in a single layer, leaving a bit of space between each slice. IMPORTANT: Place baking sheet into oven, and THEN turn the oven on to 400°F. THAT'S RIGHT! Don't preheat the oven!
Turn on the oven AFTER you add the bacon. Cook bacon slices at 400° for 15-20 minutes, without disturbing. Check them at 15 minutes, because due to varying thicknesses of bacon, cooking times can vary slightly. There is no need to turn the bacon over, or do anything else to it!
Once bacon is done cooking to your desired amount of "crispness", remove baking sheet from oven. Transfer cooked bacon to a couple layers of paper towels. The paper towels will absorb any extra bacon grease left on the bacon. Serve, and enjoy!
