Preheat the oven to 400°F (200°C).
Prepare the apples: Slice or cube the apples and toss them in a bowl with sugar and cinnamon. Set aside.
Make the dough: In a large mixing bowl, combine flour and salt. Pour in oil and milk, then gently mix with your hands until a dough forms. Do not overmix.
Roll out the dough: Place the dough between two sheets of parchment paper and roll it out. If you don’t have a rolling pin, press the dough directly into a pie plate using your hands.
Assemble the crust: Peel off the top parchment layer, place the pie plate over the dough, invert it, and trim any excess. Roll out the extra dough for the top crust.
Fill the pie: Pour the sugared apple mixture into the crust. The apples should mound slightly higher than the pie plate but not overflow.
Top the pie: Lay the second rolled-out dough over the apples. Pinch the edges of the top and bottom crust together to seal.
Vent the pie: Use a knife or fork to create 4-5 small vents on top to allow steam to escape while baking.
Bake: Place the pie in the oven and bake at 400°F for 15 minutes. Then reduce the heat to 350°F and continue baking for 20-30 minutes, until the crust is golden brown.
Cool & Serve: Let the pie cool for at least 15 minutes before slicing. Serve warm or at room temperature. Enjoy!
