Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

Roll out the thawed puff pastry and slice it into 8-10 triangular shapes. Arrange these triangles in a circular pattern.

In the center, layer slices of brie and cranberry sauce evenly.

Fold the tips of the triangular pastry over the filling to secure the wreath shape.

Whisk an egg and brush it over the entire surface. Sprinkle with chopped rosemary.

Bake in the preheated oven for 20-25 minutes until golden brown.

Let cool slightly before serving warm with crackers or fresh fruit.
