streusel-topped apple pie

By momofsixplus1

to get the thinnest, most uniform slices of apple, use a mandoline-style slicer

Ingredients

• 1/3 cup flour
• 3 tablespoons light brown sugar
• 1 tsp cinnamon
• 1/8 tsp salt
• 1/2 cup chopped walnuts(2 ounces)
• 2 1/2 tablespoons unsalted butter, melted
• 1/2 tsp vanilla extract
• 1 cup greek yogurt or sour cream
• 3 tablespoons granulated sugar
• 3 large braeburn or other tart-crisp apples( 1 3/4 pounds), peeled, cored and very thinly sliced
• one 9-inch pie shell, homemade or store-brought

Preparation

Step 1

preheat oven to 375.

in a medium bowl, combine the flour, brown sugar, cinnamon and salt. stir in the walnuts. sprinkle with the melted butter and vanilla, stir with a fork until evenly moistened. set aside the streusel topping.

in a small bowl, stir together the yogurt and granulated sugar. refrigerate until ready to use.

arrange the apple slices in the pie shell in tight stacks, arranging the stacks so that there are as few gaps as possible. the apples should be very densely packed. spread the yogurt mixture over the apples, leaving a 1/2-inch border all around. sprinkle evenly with the streusel topping, going right up to the pastry.

place the pie on a baking sheet( for any drips) bake for `10 minutes. reduce the temperature to 350 and bake for 40 minutes or until the topping is browned and the apples are bubbling. cover the edge of the pie crust with foil if it starts to get too brown.
