Whip your egg in a bowl. In a different bowl combine your bread crumbs with your olive oil. Preheat your air fryer to 350 for 10 minutes while you're preparing your chicken.
Dip each chicken tender into the egg on both sides letting excess egg drip off before putting it into the bread crumb bowl. Flip over so whole piece of chicken is covered in wet bread crumb mixture.
If not adding bacon, place these coated pieces into your air fryer basket.
If wrapping with bacon, cut 8 slices of bacon in half and lay 2 of your half pieces down next to one another horizontally.
Place your coated chicken tender in the middle. Use 2 toothpicks to secure ends of bacon pieces on to chicken. Insert at an angle so they are somewhat flat so when you put them into the basket they lay relatively flat.
Place chicken wrapped pieces into air fryer basket with toothpick sides down.
Once all pieces are in basket and aren't overlapping (we did 2 batches so they didn't) close lid and select air crisp for 12 minutes if there's no bacon, or 14 minutes if you wrapped with bacon.
Flip chicken pieces halfway through your cook cycle. If you want them really crisp spray oil on them for the last 2 minutes. Remove and enjoy!
