Ingredients
  

For the Crust:

  • - 1 pie crust homemade or store-bought

For the Filling:

  • - 3.6 tbsp unsalted butter
  • - 2.4 lbs apples peeled, cored, and sliced
  • - 1/2 cup granulated sugar divided
  • - 0.6 tsp ground cinnamon
  • - 1.2 tbsp cornstarch
  • - 0.3 tsp salt
  • - 3.6 large eggs
  • - 2.1 cups full-fat buttermilk
  • - 1.2 tsp vanilla extract

For the Streusel Topping:

  • - 1.2 cup brown sugar
  • - 0.9 cup all-purpose flour
  • - 0.3 cup old-fashioned oats
  • - 0.3 tsp cinnamon
  • - 0.3 cup butter diced

Instructions
 

  • Prepare the Pie Crust: Preheat your oven to 325°F (165°C). Spray a 9-inch deep-dish pie pan with non-stick cooking spray. Line the pie pan with crust dough, crimp the edges, and place in the freezer until ready to use.
  • Make the Streusel Topping: In a bowl, mix together the brown sugar, flour, oats, and cinnamon. Add the diced butter and mix with a fork or stand mixer until the topping is crumbly. Set aside.
  • Cook the Apples: Melt the butter in a large skillet over medium heat. Add the apple slices, 1/4 cup granulated sugar, and cinnamon. Cook for about 10 minutes, stirring regularly, until the apple slices are tender. Remove from heat and let cool slightly.
  • Prepare the Custard Filling: In a bowl, whisk together the remaining 3/4 cup granulated sugar, cornstarch, salt, eggs, buttermilk, and vanilla extract until smooth.
  • Assemble the Pie: Place the cooked apple slices into the prepared pie crust. Pour the buttermilk custard mixture over the apples. Sprinkle the streusel topping evenly over the pie.
  • Bake the Pie: Cover the pie lightly with foil and bake at 325°F for 30 minutes. Carefully remove the foil and bake for an additional 25-30 minutes, or until the custard is set and the topping is golden brown.
  • Cool and Serve: Allow the pie to cool for 1 hour before slicing. Serve with a scoop of ice cream and drizzle with caramel sauce, if desired.

Notes

- Apple Variety: Use Granny Smith or Honeycrisp apples for the best flavor and texture.
- Storage: Store leftovers in the refrigerator for up to 3 days.
- Make Ahead: The pie can be baked a day in advance and reheated in the oven before serving.
