Prepare the pie crust: Make a homemade pie crust or use a store-bought one. Roll out the dough and line a pie dish with it.
Prepare the apple filling: Peel, core, and slice the apples. Toss the apple slices with sugar, cinnamon, and a pinch of salt.
Make the caramel: In a saucepan, cook sugar and water over medium heat, stirring occasionally, until the mixture turns a deep amber color. Carefully pour the caramel over the apple filling.
Top the pie: Roll out the remaining pie dough and cut into strips. Arrange the strips in a lattice pattern over the top of the pie.
Bake the pie: Place the pie on a baking sheet and bake at 375°F (190°C) for 40-50 minutes, or until the crust is golden brown and the filling is bubbling.
Serve and enjoy: Allow the pie to cool for at least 30 minutes before serving. Serve warm, with a scoop of vanilla ice cream or a drizzle of additional caramel sauce, if desired.
