Place the Brie wheel in a small oven-safe baking dish or cast iron skillet.
Score the top of the Brie in a crosshatch pattern with a paring knife, cutting about 1/4 inch deep.
Bake 15 to 18 minutes until the center feels soft and jiggly when the dish is gently shaken.
Remove from the oven and spoon the cranberry sauce over the top, letting it pool at the edges.
Scatter the toasted pecans over the cranberries.
Drizzle with honey and sprinkle with rosemary.
Serve immediately with crackers or baguette slices for scooping, before it firms back up.
Good to Know
Score the rind and have the cranberry sauce measured out a day ahead; the Brie itself only needs its 20 minutes in the oven right before guests arrive.
