Preheat oven to 375 F. Spray the cavities of a 24-cup mini muffin pan.
Dust work surface with flour and roll out one of your puff pastry sheets to roughly 10x15 inches. Cut the dough into 24 squares.
17.3 ounces puff pastry sheets
Gently push each square into the cavity of the mini muffin tin.
Cut brie into 48 pieces. Place a piece of brie into each puff pastry shell, reserving the remaining 24 pieces of brie for the second batch.
8 ounces brie cheese
Add a few dried cranberries to each cavity and top with 1/2 teaspoon of apricot jam. Finish by sprinkling on some chopped pistachios and a little sea salt.
1/2 cup dried cranberries, 1/2 cup apricot jam, 1/2 cup chopped pistachios
Gently press the "wings" of the puff pastry inwards so they aren't hanging over the sides. Whisk the egg in a small bowl. Brush pastry with egg wash.
1 large egg
Bake in preheated oven for 15 minutes, or until golden brown and puffed up.
Remove bites from pan as soon as they are cool enough to handle. Place on wire rack to cool completely. Garnish with rosemary leaves.
Repeat for second batch.
If you have any spillage from the jam, use a rubber spatula to scoop it back into the bite as soon as the pan comes out of the oven. You may have to use a knife to separate the pastry from the sides of the pan cavity. But don’t worry! They will still look and taste great when they cool!
Remove the puff pastry from the refrigerator about 10-20 minutes before using to soften it up.
Brie rind is perfectly edible, and it isn't necessary to remove it. Especially when baking, as it helps the cheese hold its shape! I personally think it adds a subtle touch of nutty earthiness against the sweetness of the jam. However, you can certainly remove the rind if preferred.
Feel free to substitute with any flavor of jam you prefer. Homemade cranberry sauce/jam is a popular one, especially for its festive red color for the holidays. I think they would be great with fig, blueberry, strawberry, raspberry, or even apple butter!
You can leave the nuts out completely, or use your favorite variety. Walnuts, pecans, or chopped peanuts are all great choices if you aren't a huge fan of pistachios.
