Granny Smith apples, peeled and thinly sliced
grated lemon zest
9-inch basic flaky piecrust, unbaked
- Preheat oven to 375° F. In a large bowl, toss together apples, cranberries, sugar, cornstarch, lemon zest, cinnamon, and salt.
- Transfer the mixture to the piecrust. Top with granola and dot with butter.
- Bake until the apples are tender, 50 to 60 minutes. (If the top darkens too quickly, tent loosely with foil.) Let cool before serving.
