Lightly spray your air fryer basket with cooking oil spray
Place as many frozen mini tacos in your air fryer at one time in a single layer without overcrowding them. (I use a Cosori Dual Blaze and can fit about 10 tacos in at once).
Air fry the frozen tacos for 6 minutes at 400 degrees F, flipping halfway through the cook time until they are heated through and crispy.
Remove them from the air fryer and serve with your favorite toppings, such as chopped lettuce, salsa, guacamole, cheese dip, and sour cream, etc.
