Line a rimmed baking sheet with parchment paper. Place the phyllo shells on the baking sheet and set to one side.
Cut the brie into 15 roughly equal pieces and place 1 piece in each cup.
Bake until cheese is melted, approximately 5 minutes. Put a 1/4 teaspoon of strawberry preserves on top off the melted brie, smoothing it out to cover the cheese.
