Place slices in a large bowl and drizzle olive oil over the slices. Toss to combine.
Place slices in the air fryer basket in a single layer. Cook for 3-5 minutes at 380 degrees F.
Remove from air fryer and enjoy.
Notes
All air fryers cook differently. Check frequently for doneness!
If you slice your bread thicker or thinner than ½ an inch, you may need to adjust cooking times.
You may need less olive oil than I used, depending on your bread. Start with 2 Tablespoons and add more if needed. You want it to moisten all the bread so it crisps up properly, but not soaking the bread.
