I've made these a few different ways as a shout out to baked brie in a more manageable and pre-portioned size. In a pinch you can wrap crescent rolls around apple and brie slices and pop 'em in the oven. The cheese is a little understated so don't be shy with it. You might also consider bringing another cheese or two to the party if you have other interesting fruit and cheese pairings on hand.
Individual Brie and Apple Tarts
1 box (2 sheets) of puff pastry, thawed
1 green apple
1 Tbsp brown sugar, divided
1 Tbsp butter, divided
1/4 tsp cinnamon, divided
1 medium wedge of brie
flour (for rolling)
Preheat the oven to 400 degrees F. Line a sheet pan with parchment paper.
Unfold 1 sheet of puff pastry onto a lightly floured board and roll it slightly with a floured rolling pin until it's a 10 by 10-inch square. Cut the sheet into quarters with a sharp knife. Place a good-sized slice of brie and 3 or 4 this slices of apple the middle of each of the 4 squares. Sprinkle apples with cinnamon and brown sugar and top with a pat of butter. Brush the border of each pastry with egg wash and fold 2 opposite corners to the center, brushing and overlapping the corners of each pastry so they firmly stick together. Brush the top of the pastries with egg wash. Place the pastries on the prepared sheet pan. Repeat with the second sheet of puff pastry.
Bake the pastries for about 20 minutes, rotating the pan once during baking, until puffed and brown. Serve warm.
