Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Slice the bread into ¾" cubes and place them into a mixing bowl. Toss the cubes with the olive oil and seasonings. Spread them in an even layer on the baking sheet.
Bake for 20 minutes or until crispy and golden brown. Make sure to toss them halfway through the baking time. (This could take more or less time depending on how thick and dry your bread is.)
After coating the bread cubes with oil and seasonings, arrange them in a single layer on the air fryer tray. Cook at 375°F ( 190°C) for 4 minutes, toss with a spatula and cook for an additional 2-4 minutes.
