Prepare the Pie Crust: Follow your pie crust recipe through step 5, or use a pre-made crust.
Make the Filling: Mix apple slices, lemon juice, flour, cloves, nutmeg, cinnamon, sugar, and vanilla in a bowl. Let sit while preheating the oven to 400°F (204°C).
Roll Out Dough: Roll out chilled pie dough into a 12-inch circle on a floured surface. Place it into a 9×2-inch pie dish and trim the edges. Flute the edges as desired.
Add Filling: Spoon the apple mixture into the pie crust, leaving excess liquid behind in the bowl.
Prepare the Crumble Topping: Combine brown sugar, cinnamon, flour, and walnuts in a bowl. Stir in melted butter until crumbly, then sprinkle over the apples.
Bake the Pie: Place the pie on a baking sheet. Bake at 400°F for 20 minutes. Lower the temperature to 375°F and bake for an additional 30–35 minutes. Use a pie crust shield if needed to prevent over-browning.
Cool the Pie: Let the pie cool at room temperature for 3 hours to allow the filling to set.
Serve and Store: Serve with vanilla ice cream if desired. Store leftovers tightly covered in the refrigerator for up to 5 days.
