  • 1/2 cup granulated sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 tablespoon lemon juice
  • 1 cup old-fashioned rolled oats

  • A pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9-inch baking dish.
  2. In a bowl, toss sliced apples with lemon juice, sugar, cinnamon, and nutmeg. Spread evenly in the prepared dish.
