Effortless Plum Tarte Tatin

Preheat oven to 400°F.

In a large bowl, combine plums, 1/4 cup granulated sugar, lemon juice, lemon zest and vanilla extract. Let stand for 30 minutes.

Melt butter in a 9-inch ovenproof skillet over medium heat. Sprinkle remaining 1/2 cup granulated sugar evenly over melted butter.

Arrange plums, cut side up, in concentric circles in the skillet. Cook over medium heat until syrup turns deep red, about 20-30 minutes, occasionally shaking the pan slightly to prevent sticking.

Gently place the puff pastry sheet over the plums, pressing the edges down around plums. Cut several slits in puff pastry to allow steam to escape.

Bake until puff pastry is golden brown, about 30 minutes.

Allow the tart to cool completely in the skillet.

Invert tart onto a serving platter by placing it over the skillet and carefully flipping the skillet and platter together. Remove skillet slowly.
