Lay rolled out pie crust over a 9" pie plate. Lifting the sides of the crust, gently press the crust into the pan. Using a knife, trim the edges of the crust, then crimp the edges to make a classic ruffled edge. Using the tines of a fork, poke holes over the bottom and sides of the pie crust. This is called docking. Set aside.
In a large bowl, toss together peaches, brown sugar, cinnamon, nutmeg, ground cloves, vanilla and flour until combined.
In a small bowl, combine brown sugar, flour, and oats; using your hands, or a pastry cutter, work in butter until large clumps form,
Transfer peach filling to pie shell, then sprinkle crumble evenly over the top.
Place pie on a rimmed baking sheet and bake until juices are bubbling and topping is golden, about 1 hour. Let cool on a wire rack 1 - 3 hours before serving.
Notes
Tips for success:
Make sure the canned peaches are very well drained. Any access liquid will cause the bottom of the pie crust to be soggy.
Once you've placed the pie crust in the pie pan, docked the crust and formed the design around the edge of the crust, let the pie shell rest in the refrigerator for 20 minutes before adding filling. This will allow the pastry to firm up and resist soaking up any liquid before baking.
When making the crumble topping, keep the cubed butter in the refrigerator to keep it cold. If the butter is too warm and soft, it will be difficult to create those "lumps" for the crumble topping.
Make this peach pie using our fresh Colorado Palisade Peaches. Substitute nine fresh peaches for the canned peaches. You don't need to peel them, just slice and proceed with the recipe.
