Preheat the oven to 400 F. Remove the pie crust from the fridge and roll it into a circle, about 1/8 inch thick. Transfer the crust into a standard pie dish and shape the edges how you like.
Pour the apple mixture into the pie crust and use your fingers to press the apples down into any empty space. We want them compacted down as much as possible!
Pour about 1/2 of the miso caramel evenly over the apples.
Use your fingers to crumble the streusel on top of the pie, making sure to cover all of the pie (except the exposed crust).
Transfer the pie to the oven and bake for 35-45 minutes, until the streusel and pie crust are golden brown. Check the pie after 20 minutes -- if the crust is browning too quickly, remove the pie from the oven and carefully cover the crust with tin foil and place it back in the oven for the remainder of the time.
Let the pie cool for a few minutes then dive in! Serve with ice cream and extra miso caramel. Enjoy!
