Homemade bagel chips are a simple treat you can make to use up stale bagels. Perfect for dips and as a base for hors d'oeuvres, thinly sliced bagels become dry and crispy in the oven. You can season the bagel slices however you wish to make sweet or savory chips. Once they are dried and browned, the bagel chips will keep in an airtight container at room temperature for up to one week.
Preheat the oven to 350 degrees Fahrenheit.
Place the bagel with the flat bottom on a cutting board, and cut downward to form 1/4-inch-thick slices with a large serrated knife. Firmly hold on to the bagel to prevent it from slipping. You may use fresh bagels if you wish, but crispy chips are a good opportunity to use up stale, day-old bagels.
Arrange the bagel slices in a single layer on a baking sheet lined with parchment paper or a silicone baking mat. Avoid overlapping the bagel slices to guarantee each piece becomes browned and crisp.
Brush the chips with oil, or spray with nonstick cooking spray. Season the bagel slices. Use salt, pepper and any dried herbs and spices you enjoy to make savory chips. Garlic powder, rosemary, onion powder and cayenne pepper are all excellent options. Sprinkle the slices with cinnamon and sugar, or brown sugar for sweet chips.
Bake the bagel slices until they are golden brown -- about 15 to 20 minutes. The bagels become crispier as they cool. Serve them warm or at room temperature.
