Instructions
Preheat oven to 350 degrees and place the pie crust in a 9-inch deep-dish pie. Decorate or crimp the curst as desired and place in the refrigerator while you make the filling.
In a large bowl, combine the sliced apples, orange zest, lemon zest, lemon juice, brown sugar, cinnamon, nutmeg, and cornstarch. Mix well and set aside while you make the crumb topping.
To make the topping, add the flour, granulated sugar, brown sugar, salt, and oats to the bowl of a stand mixer fitted with the paddle attachment. Mix to combine.
Add the cubed butter and mix on low to incorporate until the dough starts to come together.
Transfer the apples to the pie crust, spreading them evenly in the crust. Then crumble the topping over the apples.
Place the baking dish over a rimmed baking sheet (in case the apples bubble over) and bake at 350 degrees for 45-60 minutes or until the topping is browned/crisp and the apples are bubbling. Use a pie shield to prevent your crust from burning if necessary.
Cool the pie at least 2-3 hours before serving. Serve warm with vanilla ice cream or homemade whipped cream.
Notes
For this recipe, I used a mixture of 3 Granny Smith Apples, 1 Honey Crisp Apple, and 1 Golden Delicious Apple but any combination of baking apples will work. You’ll need more or less apples depending on the size, just be sure to use 2 pounds.
Read my guide to the best baking apples if you want to experiment with different apples for this recipe.
This pie is best the day it's baked but can be made a day ahead. Bake the pie as directed then cool completely. Refrigerate once cooled and warm in the oven before serving or serve it cold or room temperature.
