Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Toss sliced apples (peeled and 1/2-inch thick) with 1/4 cup granulated sugar, 1 tsp ground cinnamon, and 1/4 tsp ground nutmeg in a 9x13 inch baking dish until evenly coated, then spread in an even layer.
  2. Step 2: In a medium bowl, combine 1/2 cup all-purpose flour, 1/2 cup rolled oats, 1/4 cup packed brown sugar, and 1/4 cup chopped walnuts. Add 1/4 cup cold cubed butter and use a pastry cutter to cut butter into the mixture until it resembles coarse crumbs.
  3. Step 3: Sprinkle the crumble topping evenly over the apples in the baking dish.
  4. Step 4: Bake for 45 minutes, or until the topping is golden brown and the apples are bubbling around the edges.
  5. Step 5: Let the crisp cool for 15 minutes before serving to allow juices to set.
