A French classic, this Tarte Tatin comes together quickly and easily with a few simple ingredients. It looks impressive but anyone can make it!
Preheat the oven to 400F.
Peel, quarter, and core the apples. Set aside.
In a 10-inch oven-proof skillet, sprinkle the sugar evenly over the bottom and drizzle with water. Cook over medium heat, stirring occasionally, until the mixture bubbles and turns light amber, 5 to 7 minutes. Stir in the butter until melted. (It will bubble up so be careful.)
Add the apples. Cook, stirring the apples every few minutes until the caramel is a deep amber color, about 15 minutes. Remove from the heat and arrange the apples, curved side down in concentric circles in the skillet.
Roll out the puff pastry slightly and cut it into an 11-inch circle. Place over the apples, tucking the edges down with a spatula. Place on a rimmed baking sheet.
Bake for 35 to 40 minutes or until the puff pastry is a deep golden brown on top.
Let cool on a wire rack for 15 minutes (up to 30 if using a cast-iron skillet). Carefully invert the tart onto a rimmed serving plate.
