Air fryer croutons are so much better than packaged croutons because of their texture. They are crisp, but not hard, and seasoned exactly how we like it!
Add the butter, garlic salt, parsley, and onion powder to a large mixing bowl and stir to combine.
Add the bread cubes to the bowl with the butter and toss to coat. Let sit for 2 minutes for the bread to soak up the butter.
Place bread cubes in an air fryer basket. Air fry at 400 degrees for 3 minutes. Toss and continue cooking for 2 minutes more or until croutons are golden brown.
Notes
Store croutons at room temperature in a resealable bag with as much air removed from the bag as possible.
