Plantain Tarte Tatin

1 . Stage

Preheat oven to 375 degrees F (190 degrees C).

2 . Stage

Heat an oven-proof skillet over medium heat. Sprinkle white sugar evenly into the bottom of the skillet; cook until sugar melts and turns golden brown, about 1 minute. Reduce heat to low and stir butter into sugar. Stir cinnamon into butter mixture and remove from heat.

3 . Stage

Dip each plantain slice into butter mixture to coat on both sides. Arrange coated plantains in a shingled pattern to cover the bottom of the skillet.

4 . Stage

Spread puff pastry sheet over plantains, tucking corners into the skillet.

5 . Stage

Bake in the preheated oven until puff pastry is golden brown, 30 to 35 minutes. Remove from oven and cool briefly. Place a serving plate upside-down over the top of the skillet; flip the skillet to remove tarte tatin from the pan.

6 . Stage

Whisk mascarpone cheese and confectioners' sugar together in a bowl until smooth. Spread a large dollop of mascarpone mixture over the top of the plantains. Serve with remaining mascarpone mixture on the side.
