Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Peel, core, and thinly slice 6 medium Granny Smith apples. In a large bowl, toss the apple slices with 1/4 cup granulated sugar, 1 1/2 tsp ground cinnamon, 2 tbsp lemon juice, and 1/4 tsp ground nutmeg until evenly coated.
  2. Step 2: Transfer the apple mixture into a 9x9-inch baking dish, spreading into an even layer.
  3. Step 3: In a separate bowl, combine 1 cup rolled oats, 1/2 cup all-purpose flour, and 1/3 cup packed light brown sugar.
  4. Step 4: Add 6 tbsp cold unsalted butter cubes and 1/4 tsp salt to the oat mixture. Using your fingertips or a pastry cutter, work the butter into the dry ingredients until the topping resembles coarse crumbs.
  5. Step 5: Sprinkle the oat topping evenly over the apples.
  6. Step 6: Bake uncovered for 40-45 minutes until the apples are tender and the topping is golden brown and crisp.
  7. Step 7: Let cool slightly before serving, optionally with vanilla ice cream.
