- 8 large Golden Delicious apples (about 3 1/2 pounds), peeled, cored, halved, thinly sliced
- 3/4 cup (packed) dark brown sugar
- 2 tablespoons fresh lemon juice
- 1 teaspoon grated lemon peel
- 1 teaspoon ground cinnamon
- 1/2 cup (1 stick) unsalted butter, cut into pieces, room temperature
Preheat oven to 375°F. Butter 13x9x2-inch glass baking dish. Toss apples, 1/4 cup sugar, lemon juice, and lemon peel in prepared dish. Whisk flour, baking soda, cinnamon, and remaining 1/2 cup sugar in medium bowl. Add butter and egg yolk and rub in with fingertips until mixture forms moist clumps. Sprinkle topping over apples. Bake until apples are tender and topping is golden and crisp, about 28 minutes. Cool 20 minutes. Serve crisp warm with vanilla ice cream.
