Line the outer basket with aluminum foil and pre-heat the air fryer to 390° F. You can also add 1-2 slices of bread to the bottom basket to soak up the grease.
Cut the bacon slices in half (or don't, this is optional) and arrange them in the basket in a flat layer. Cook the bacon 5 minutes, then flip and cook for another 3-4 minutes depending on how you like your bacon. If you like it extra crispy, cook it for 4-5 minutes after flipping (total time 8-10 mins). When finished, remove the bacon strips from the air fryer and transfer to a paper towel lined plate.
