Place the bacon in a fairly single layer in the air fryer, cutting the bacon in half crosswise if it allows you to fit in more pieces. Remember that the bacon will shrink as it cooks, so that a bit overlap is fine.
Set your air fryer to dual heat for 7 minutes. If you have a temperature shoice, set it for 375°F; not all air fryers give you a choice to set the temperature,some just have on and off functions. After the 7 minutes is up, check, and if it is done, remove it to a paper towel lined plate. If you prefer it crispier add 1 to 4 more minutes.
