If not peeling the apples, wash and dry them. If using peeled apples, peel them and pat dry with paper towels.
6 Granny Smith apples, 3 Gala apples
Core the apples and slice them into ¼-inch slices. Place in a large mixing bowl.
Squeeze lemon juice over the apples and mix well to coat. The lemon juice will keep the apples from browning.
1 lemon
In a medium bowl, mix together brown sugar, granulated sugar, orange zest, salt, apple pie spice, and ginger. Sprinkle the brown sugar mixture over the apples and mix well.
4 tbsp dark brown sugar, 2 tbsp granulated sugar, 1 orange, ½ tsp kosher salt, 1½ tsp apple pie spice, ½ tsp ground ginger
Pour the apples onto the prepared sheet pan and spread them to an even layer. Loosely cover with foil that has been sprayed with nonstick cooking spray.
Bake the apples at 425°F for 20 minutes, or until the apples have softened and some juices have released.
Remove the sheet pan from the oven and carefully remove the foil. Reduce the oven temperature to 375°F.
