Transform stale bagels into crisp bagel chips by popping them in the air fryer for a satisfying snack. Bagels don't last long before going stale, usually only three to five days.

As long as there is no mold, stale bagels aren't harmful to eat. For bagel chips that are uniform in shape, make 1/8th-cuts around the roll.

You can also slice the bagels in half, then tear or cut them into smaller pieces to fit in the air fryer. Next, spray or brush olive oil and seasonings onto the bagel pieces.

Grate parmesan cheese over the chips for a savory flavor. Pop them in the air fryer at 350 degrees F, cook for a few minutes, shake the basket, and cook for a few more minutes.
