Preheat oven to 350°. Slice off the top of sourdough boule and reserve; remove inside of the bread to create a bowl.

In a small mixing bowl, combine butter, garlic, thyme and marjoram; brush mixture inside bread boule, completely covering sides and bottom.

Place brie cubes inside bread boule and top with reserved lid. Place on a baking sheet and bake for 15 to 25 minutes or until cheese is melted. Cut bread into wedges and serve hot.
