Preheat your oven to 200°F (93°C) and line a baking sheet with parchment paper.
Wash and dry the apples. Core them and slice them thinly using a mandoline slicer or a sharp knife to ensure uniform thinness. Aim for about 1/8 inch thick.
In a large bowl, toss the apple slices with lemon juice to prevent browning.
In a small bowl, mix together the granulated sugar, ground cinnamon, and a pinch of salt.
Sprinkle the cinnamon sugar mixture over the apple slices evenly and toss gently to coat all the slices.
Arrange the apple slices in a single layer on the prepared baking sheet, making sure they do not overlap.
Bake the apple slices in the preheated oven for 1.5 to 2 hours, flipping them halfway through. Bake until they are crisp and lightly browned.
Once done, remove the apple chips from the oven and let them cool completely, as they will continue to crisp up as they cool.
Store in an airtight container for snacking or share them fresh with family and friends!
