Make the pie crust recipe and set it in the fridge to chill. Meanwhile, make the caramel sauce and set aside to cool a bit.
1 double pie crust
Preheat oven to 400 degrees F.
Roll out the bottom crust on a lightly floured surface. Transfer it to a 9-inch pie plate and set in the fridge to stay cold while working on the filling.
To make the filling, peel and slice the apples into 1/4-inch slices. Toss them in a large bowl with the flour, sugar, lemon juice, lemon zest, cinnamon, cloves, and nutmeg until evenly coated.
6-7 large apples, 1/4 cup (31g) all-purpose flour, 1/2 cup (100g) granulated sugar, 2 Tablespoons fresh lemon juice, 2 teaspoons lemon zest, 1 1/2 teaspoons ground cinnamon, 1/4 teaspoon ground cloves, 1/4 teaspoon ground nutmeg
Transfer the apple pie filling to the bottom crust, mounding the apples slightly in the center. They will bake down as they cook. Drizzle 1/2 cup of the caramel sauce over the top of the apples.
1 cup caramel sauce
Roll out the top crust too cover the pie. You can use a solid crust with slits cut into it to vent, or cut the top crust into strips and weave into a lattice crust. There is also a streusel recipe in the notes below if you prefer a Dutch caramel apple pie.
Beat the egg with a tablespoon of water, then brush the egg wash over the top crust. Sprinkle with coarse sugar, if desired.
1 egg, 1 Tablespoon water, Coarse sugar
Bake for 20 minutes, then decrease the oven temperature to 375 degrees F and continue to bake for another 40-50 minutes, or until the crust is golden brown and the filling is bubbling inside. If the top crust starts getting too dark around the edges, cover them with aluminum foil or a silicon pie protector if you have one.
Let the pie cool for at least 4 hours before serving so that the filling has time to set up. To serve, drizzle the whole pie or each slice of pie with additional caramel sauce.
