Step 1

Heat the oven to 350°F.  Grease a 9 x 13-inch baking dish with cooking spray or butter.

Step 2

In a large mixing bowl, toss together the apples and lemon juice until evenly combined.  Add in the brown sugar, flour and cinnamon, then toss until evenly combined.  Transfer the apples to the prepared baking dish and spread out in an even layer.

Step 3

In the same mixing bowl, stir together the oats, flour, brown sugar, pecans, cinnamon and salt until combined.  Drizzle the melted butter over the mixture, then briefly toss until combined.  (Try not to overmix — you want the topping to be clumpy.)  Sprinkle the mixture evenly over the apple filling.

Step 4

Bake for 40-50 minutes, or until the apple filling is bubbly and the topping is nice and crisp.*  Transfer to a wire baking rack.

Step 5

Serve warm, topped with vanilla ice cream and caramel sauce if you’d like.
