Preheat your oven to 350°F (175°C) and place a rack in the middle position. Line a small baking dish with parchment paper for easier cleanup.
Make the cranberry chutney by combining cranberries, sugar, orange juice, honey, chopped rosemary, orange zest, cinnamon, and salt in a medium saucepan. Bring to a simmer over medium heat.
Cook the chutney for 8-10 minutes, stirring occasionally, until cranberries have burst and the mixture has thickened to a jam-like consistency. Remove from heat and let cool slightly.
Prepare the brie by placing it on the parchment-lined baking dish. If desired, score the top rind in a crosshatch pattern (this is optional but helps the cheese melt more evenly).
Bake the brie for 12-15 minutes until it feels soft and yielding when gently pressed in the center. It should be warm throughout but still hold its shape.
Remove the brie from the oven and carefully transfer to a serving plate if desired.
Top the warm brie with the cranberry chutney, either spooning it over the entire wheel or allowing some to cascade down the sides for a more dramatic presentation.
Garnish with a sprig of fresh rosemary if desired, and serve immediately with crackers or sliced baguette.
