Step 1

Thaw the puff pastry according to package directions.

Step 2

Preheat the oven to 400°F. Spray a 24-well mini muffin pan with non-stick cooking spray. Place the brie in the freezer for 20 minutes or until firm to the touch.

Step 3

On a well floured surface, roll the sheet of puff pastry into a 10x15-inch rectangle. Cut the pastry into 4 strips lengthwise. Then, cut the pastry crosswise into 6 strips, creating 24 squares. Press the pastry squares into each well of the muffin pan, letting the excess stick up over the edges.

Step 4

Cut the firm brie into 24 (½-inch) slices. Place a piece in the center of each pastry square. Top each with about 1 teaspoon of cranberry sauce. Sprinkle with chopped pistachios.

Step 5

Bake for 15 minutes or until the puff pastry is golden brown on the edges and the cheese is bubbly. Let cool in the pan for 5 minutes. Remove the bites from the pan and garnish with sea salt and pepper, if desired.
