Make a puff pastry apple tart when you need a quick, four ingredient dessert that's sure to impress guests. Sliced apples are tossed in a cinnamon-sugar mixture and layered on top of a buttery puff pastry before baking to perfection in the oven.
Preheat oven to 425 degrees Fahrenheit and line a baking sheet with parchment paper. Set aside.
In a bowl, combine brown sugar and cinnamon. Peel and core apples, then cut into thin slices. Toss apples in sugar mixture until evenly coated. Set aside.
Unfold thawed puff pastry onto your prepared baking sheet. Using a rolling pin, roll a few times in each direction to remove creases.
Layer apple slices onto puff pastry while leaving a 1" border around the edges.
Bake for about 18-20 minutes, or until puff pastry is lightly browned around edges and apples pierce through easily with a toothpick.
Cool on a cooling rack until ready to serve. Tart can be served warm or at room temperature. Optionally, top with a scoop of vanilla ice cream or whipped cream.
Notes
Leftovers will keep for about 2 days at room temperature or up to 5 days in the refrigerator in a tightly sealed container.
Brown sugar can be substituted with granulated sugar if desired.
I recommend using a firm apple like granny smith, honeycrisp, or golden delicious for baking. Softer apples tend to get mushy and mealy when baked.
