Preheat the oven to 400 degrees.Keep the pie crust in the fridge until you are ready to use it.Peach Pie
Next, peel and slice the peaches. You want them to be 1/4-inch thick.
Then, place them in your large bowl along with the flour, brown sugar, lemon juice, salt, and cinnamon. Stir all of this together to fully combine and coat your peaches.
Once the peach filling is ready, add it to your chilled pie crust and set aside.
Crumble Topping
Add the oats, flour, sugar, cinnamon, and salt into a medium mixing bowl. Mix the ingredients to combine.
Melt the butter and pour it over the oat mixture. When you stir it together, it will get a crumbly texture.
Pour the crumble topping on top of the pie.
Cover the pie with aluminum foil and bake for 35 minutes.
Then, remove the aluminum foil covering and bake it for another 15 to 20 minutes. It’s ready when the filling is all bubbly and the crumb topping has turned that beautiful golden brown.
Set the pie on a wire rack to cool down to room temperature.
