• Cut your bread into roughly 1x1 inch cubes and place into a large mixing bowl.
• Pour the olive oil over the top of the bread and then spread the salt and garlic powder over the bread cubes.
• Use tongs or a spoon to gently toss the bread cubes to coat them.
• Sprinkle on the parmesan cheese and toss again to combine.

For the Air Fryer

• Spread the bread cubes in the basket of the air fryer, leaving space between each cube.
• Set the air fryer to 400 F.
• Cook the croutons for 6 to 10 minutes or until they turn golden brown and toasted, shaking the basket halfway through the cooking process.
• Remove from the air fryer and allow to cool before storing or serving with your favorite salad or soup.
