Slice bagels very thinly into strips.

Spread each slice/piece with butter.

Without overlapping, place on parchment lined baking sheet.

Sprinkle thickly with cinnamon sugar.

Place baking sheet on top oven rack on low broiler setting for 1-3 minutes.

Watch very closely. These crisp up quickly and can burn easily.

These bagel chips crisp up as they cool.

Serve once cool or store in an airtight container for several days.
