Step 1

Preheat oven to 400 degrees and prepare your pie crust (if using homemade press into a round pie dish) and bake for 10 minutes.

Step 2

Stir together cinnamon and 1/2 cup sugar. Toss apple slices in the cinnamon-sugar mixture. Arrange apples in the pie crust, trying to get them as tightly packed as you can. Sprinkle any remaining cinnamon-sugar mixture over the top.

Step 3

In a medium bowl whisk together flour and remaining 1/3 cup sugar. Cut in butter using a pastry cutter or your fingers, til crumbly. Sprinkle mixture over apples.

Step 4

Bake for 35-40 minutes until top is golden brown. Sprinkle coarse sea salt over the top (if desired) and serve with vanilla ice cream and caramel sauce.

Step 5

Store uncovered in the fridge up to 3 days. Individual slices can be heated in the microwave later if desired.
