How to Make It
Preheat oven to 225°F. Place 2 wire cooling rack inside 2 rimmed baking sheet or cover 2 baking sheets with parchment paper.
Wash and dry outside of apples. Using a mandolin*, slice each apple into 1/16-inch thick rings. Use a small round pastry cutter or a knife to cut out the core of each slice, making doughnut-like rings of apple. Toss apple rings in a bowl with cinnamon until evenly coated.
Spread apples on prepared baking sheets without allowing any of them to overlap. Bake in preheated oven for 2 hours, flipping the apples over halfway through baking. Allow to cool to room temperature.
If you do not have a mandolin, a very sharp knife can be used to slice the apples, but the slices won’t be as consistent. A mandolin is an affordable piece of kitchen equipment that makes this recipe infinitely easier, and once you taste these Apples Chips, we promise you’ll use the mandolin again and again to make more.
