Preheat oven to 350ยบ F. Unwrap brie and place it on a parchment-lined baking sheet. Bake for 14 minutes.
While the brie bakes, combine cherries, honey, balsamic vinegar, and salt in a small sauce pan over medium heat. Bring to a boil, and then reduce heat and simmer, stirring occasionally, until the juices are slightly thickened, about 12 minutes.
Transfer brie to a serving platter and top with cherry mixture. Sprinkle pecans over the top and serve warm with baguette slices.
