This cobbler is my surprise dessert! No one ever guesses that the secret ingredient is zucchini. Everyone says it tastes like apples. It's fantastic to make for a potluck supper or to serve to a crowd. —Joanne Fazio, Carbondale, Pennsylvania
Preheat oven to 375°. In a large saucepan over medium-low heat, cook and stir zucchini and lemon juice until zucchini is tender, 15-20 minutes. Stir in sugar, cinnamon and nutmeg; cook 1 minute longer. Remove from the heat; set aside.
In a large bowl, combine flour and sugar; cut in butter until mixture resembles coarse crumbs. Stir 1/2 cup into zucchini mixture. Press half the remaining crust mixture into a greased 15x10x1-in. baking pan. Spread zucchini mixture over top; crumble remaining crust mixture over zucchini. Sprinkle with cinnamon.
Bake until golden and bubbly, 35-40 minutes. Cool in pan on a wire rack.
