Ingredients:
- 3 large Granny Smith or Honeycrisp Apples (approx. 1.5 lb)
- 1 tbsp melted unsalted butter
- 1 tsp ground cinnamon
- 1 tbsp granulated sugar
Instructions:
- Preheat your oven to 225°F (107°C).
- Core the apples and slice them into rounds approximately 1/8-inch thick using a mandoline or a sharp chef's knife.
- Toss the apple slices in a large bowl with the melted butter, cinnamon, and sugar until every slice is lightly coated.
- Line baking sheets with parchment paper and arrange apple slices in a single layer, ensuring they do not overlap.
- Bake for 2 to 3 hours, flipping the chips every 60 minutes, until the edges curl slightly and the centers feel firm and dry.
- Remove from the oven and immediately transfer to a wire cooling rack to allow remaining moisture to evaporate and the chips to become crisp.
