Cut the beef slices into strips or squares, then place them in a plastic zipper bag with the Teriyaki sauce. Massage the sauce around the beef to ensure it’s evenly coated, then place the bag in the refrigerator and marinate the beef for 24-48 hours.

When ready to cook, remove the beef from the marinade and pat it dry with paper towels.

Place the beef pieces in a single layer in the air fryer basket. Air fry at 200 degrees F for 2 hours, flipping it halfway, checking to see if it’s completely dehydrated and at 160 degrees F. If not, continue to air fry at 15 minute intervals until it is.

Allow the jerky to cool, then store it in an airtight container.
