For the pie: Preheat the oven to 400˚F. Place the pie crust into a 9-inch pie dish. Trim any excess dough then flute the edges. In a large bowl, combine the Del Monte Sliced Peaches in Heavy Syrup, brown sugar, all purpose flour, lemon juice, and cinnamon. Mix to combine then set it aside.

For the crumble: Add the brown sugar, cinnamon, all purpose flour, and unsalted butter to a medium sized bowl. Mix until a crumble mixture has formed.  Spoon the peach filling into the prepared pie crust, leaving any excess liquid in the bowl. Sprinkle the crumble mixture on top until it is completely coated.

Place the pie dish onto a baking sheet and bake it in the oven for 20 minutes. Lower the oven temperature to 375˚F and bake for an additional 30 minutes until the crust and topping are golden brown and the filling is bubbling.

Remove the pie from the oven and allow it to cool to room temperature. Enjoy!
