• Begin by preheating your oven to 350°F (175°C) and prepare a baking sheet with aluminum foil.
• Arrange the bacon strips on the baking sheet in a single layer. In a mixing bowl, combine the pecans, brown sugar, chili powder, and a pinch of sea salt, then evenly distribute this mixture over the bacon.
• Place the baking sheet in the oven and cook the bacon for 18 to 20 minutes, or until crispy. Once cooked, let it cool on a rack before chopping into small pieces.
• Melt the butter in a nonstick skillet over medium-high heat. Add the sliced apples along with 1 tablespoon of maple syrup, and sauté, stirring every minute or so, until the apples are tender and nicely browned, which should take about 8 minutes.
• After the apples are done, mix in the remaining 2 tablespoons of maple syrup and the cinnamon, then transfer the apple mixture to a bowl.

To Bake the Dish:

• Prepare a piece of parchment paper slightly larger than the round Brie and place it in a baking sheet. Position the Brie on the parchment and top it generously with the sautéed apples.
• Bake the Brie for about 5 minutes, then sprinkle the chopped bacon mixture over the top and continue to bake for an additional 2 to 3 minutes until everything is bubbly and golden.
• Using a spatula, carefully transfer the baked Brie onto a serving platter. Top with a pinch of sea salt and add fresh rosemary if desired.
