Preheat the oven to 375°F (190°C) and line a baking dish with a piece of parchment paper. Place the wheel of brie into the parchment lined baking dish. Score the top of the brie lightly in a diagonal pattern with a sharp knife and drizzle 1 tablespoon of maple syrup on top of the brie. Set aside.
While the oven preheats, make the apple topping: Add 2 tablespoons of butter to a medium-sized pan over medium heat. When the butter is melted, add the apple slices, ground cinnamon and ground nutmeg and stir to combine. Cook the apples over medium heat, stirring often, until tender and softened, about 8-12 minutes. *If you notice the apples starting to brown too much, turn to medium-low heat*
Once the apples are softened, add the vanilla extract and maple syrup to the pan and cook for 2 more minutes, stirring a few times. Remove the pan from the heat and put a lid on the pan to keep the cooked apple slices warm.
Bake the brie in the preheated oven for 18-22 minutes or until cheese is starting to bubble and almost ooze out. When the brie is baked to your liking, remove from the oven and spoon the cooked apple slices on top of the brie. Spoon any of the maple sauce in the apple pan over the baked brie as well. Then, garnish with chopped pecans and fresh thyme leaves. Serve with your favorite crackers, toasted slices of baguette (crostini) or a crusty bread for dipping into the brie.
Notes
Make crostini to serve with this baked brie: Preheat your oven to 400°F and slice your baguette into 1-inch thick slices. Brush the baguette slices with olive oil on one hand and place on a single layer on a baking sheet. Toast for 10 minutes, making sure to flip the slices halfway through. Alternatively you could use a sourdough baguette to make the crostini.
