Walnut Streusel Apple Pie - cooking recipe

Ingredients

1 frozen pie crust
For topping
6 tablespoons unsalted butter, softened
1/2 cup firmly packed brown sugar
2/3 cup all-purpose flour
1 teaspoon ground cinnamon
1 cup chopped walnuts
For filling
3 lbs granny smith apples (approx. 6) or 3 lbs mixture of firm apples (approx. 6)
1/2 cup firmly packed brown sugar
1/4 cup granulated sugar
2 tablespoons all-purpose flour
1 tablespoon fresh lemon juice
3/4 teaspoon cinnamon

Preparation

To make topping: In a small bowl with your fingertips blend butter, brown sugar, cinnamon and flour until smooth and blend in nuts. Chill topping, covered.
To make filling: Peel and core apples. Cut apples into 1/2-inch wedges and in a bowl toss with remaining filling ingredients to coat.
Preheat oven to 350\u00b0F Unfold defrosted, store-bought dough into a well-seasoned 10-inch cast-iron skillet or 10-inch deep-dish (1 1/2-quart) pie plate, easing to fit.
Spoon filling into shell, bake pie in middle of oven for 1 hour (pie will not be completely cooked) and remove from oven.
Crumble topping over center of pie, breaking up any large chunks. Bake pie in middle of oven 30 minutes more, or until crust is golden and filling is bubbling.
Cool pie on a rack and serve warm or at room temperature with vanilla ice cream or Sour Cream Ice Cream (also on this site).
