For the apple filling: Wash, peel, core, and slice the apples into slices. Place them in a large bowl.
Whisk together the sugar, flour, cinnamon, and salt. Sprinkle over the apples and toss to coat. Spread the apple mixture into the un-baked pie crust. Drizzle the caramel sauce over the apples.
For the crumb topping, combine the flour, brown sugar, cinnamon, nutmeg, and melted butter in a small bowl. Mix together until crumbly. Sprinkle over the top of the pie.
Bake at 400° for 45-55 minutes, or until the apples are tender and the crust is golden brown.
Let the pie cool for at least 30 minutes on a wire rack before slicing, but it will slice best if cooled completely.
Drizzle caramel sauce over the top of each slice. It's awesome served with a scoop of vanilla ice cream!
Notes
This is a large pie, so make sure you use a large, deep dish pie pan!
I like to put the pie dish on the lowest rack of my oven so the bottom crust will brown before the top gets too dark.
I make the dough and caramel sauce the day before, so that time is not included in the 25 minutes.
