Preheat oven to 375° F.
Cut off 1/4 inch of pointed end of head of garlic (save small pieces for another recipe). Place cut side up in a piece of aluminum foil. Place rosemary on top. Bring sides of foil up to make a deep bowl, but do not enclose garlic completely. Pour olive oil over top of garlic. Bake for 40-45 minutes in preheated oven. Cool.
Squeeze garlic so that the cloves pop out of their papery jackets. They should be creamy. Smash them and spread on top of brie (including some of the rosemary). Place brie in ovenproof dish. Top with tomatoes and pine nuts. Increase oven temperature to 400° F.
Bake brie until warm and softened, about 13 to 18 minutes. If topping is getting too browned, cover loosely with aluminum foil during last portion of baking.
Sprinkle slivers of fresh basil on top. Surround with crostini and/or apple slices. Garnish with sprigs of fresh herbs and, if using, drained imported olives. Provide a spreading knife.Servings: 6 to 8
