Ingredients
Equipment
Method
Preheat and prep the pie
- Preheat the oven to 375°F, placing a rack in the lower-middle position for even baking.
- Fit the unbaked 9-inch deep dish pie shell into a deep-dish pie plate and crimp the edge decoratively.
Make the apple filling
- Toss the apple slices with granulated sugar and brown sugar, cinnamon, nutmeg, cornstarch, lemon juice, and caramel sauce until evenly coated.
- Pile the apple mixture into the pie shell, mounding well so the center is higher than the edges.
Make the oat crisp topping
- Combine rolled oats, all-purpose flour, packed brown sugar, cinnamon, and salt in a bowl to form an even dry mix.
- Cut the cold cubed unsalted butter into the oat mixture until large clumps form.
- Pile the crumble generously over the apples and press very gently so the topping adheres.
Bake
- Bake the pie for 60-65 minutes, until the crumble is deeply golden and the filling bubbles at the edges.
- Tent with foil after 40 minutes if browning too quickly, then continue baking until fully done.
Finish and serve
- Drizzle with extra caramel and serve once the pie has cooled slightly so the filling sets.
Notes
For clean slices, let the pie cool at least 30 minutes before cutting. Store covered in the refrigerator up to 4 days; reheat slices at 325°F for 10-15 minutes to re-crisp the topping. Freezing is not recommended because the caramel-bubbling apple filling and oat crumble can soften after thawing. If you want a lighter option, use a reduced-sugar caramel sauce and reduce granulated sugar by 1-2 tablespoons.
