Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. In a large mixing bowl, toss 5 medium peeled and 1/4-inch thick sliced Granny Smith apples with 1/4 cup granulated sugar, 1 tsp ground cinnamon, and 1 tbsp lemon juice until evenly coated and fragrant.
  2. Step 2: Transfer the apple mixture into a greased 9x9-inch baking dish, spreading out evenly.
  3. Step 3: In a separate bowl, combine 1 cup rolled oats, 1/2 cup all-purpose flour, 1/3 cup packed brown sugar, 1/4 tsp salt, and 1/3 cup chopped pecans. Add 6 tbsp cold cubed unsalted butter. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs.
  4. Step 4: Sprinkle the oat topping evenly over the apples. Bake uncovered for 40-45 minutes until the topping is golden brown and the apple juices are bubbling around the edges.
  5. Step 5: Remove from oven and let cool for 10 minutes before serving warm, optionally with vanilla ice cream.
