Peel, core, and slice the apples. Place in a large bowl with the flour, sugar, lemon juice, and spices. Stir to combine.
In a medium bowl, stir together flour, brown sugar, and salt for the crumb topping. Drizzle in the melted butter; combined with a fork until crumbs form. Set aside.
Place pie crust in a 9-inch deep-dish pie plate. Carefully pour in apples, arranging to mound up in the middle (they should mound up quite a bit). Carefully place crumbs on top of the apples, pressing lightly on the sides so they stay in place.
Place pie on a rimmed baking sheet. Bake for 1 hour and 10 minutes to 1 hour and 20 minutes, or until crust and crumb topping are golden and the juices are bubbly. Allow to cool completely before cutting and serving.
Notes
Keep an eye on the pie while baking. If crust or crumb topping starts to get too dark, cover edges or top of pie very gently with foil for the remainder of the baking time.Makes 1 9-inch deep-dish pie
