Preheat and Prepare: Position a rack in the center of your oven and preheat to 375°F (190°C). Place the chilled wheel of brie into a small, oven-safe ceramic baking dish or a dedicated brie baker.
Toast the Almonds: In a small, dry skillet over medium heat, toast the sliced almonds, shaking the pan frequently until they are fragrant and turn a light golden-brown, about 2–4 minutes. Immediately remove them from the pan and set aside to prevent burning.
Create the Glaze: In a small saucepan, combine the apricot preserves, orange juice, and ground cardamom. Warm the mixture over medium-low heat, stirring continuously for about 2 minutes until it becomes smooth and pourable.
Combine the Toppings: In a small bowl, mix the toasted almonds and the chopped dried apricots. Pour the warm apricot glaze over the top and stir until the nuts and fruit are evenly coated.
Assemble and Bake: Spoon the apricot and almond mixture evenly over the top of the brie wheel. For easier handling, place the baking dish on a larger baking sheet. Bake for 12–18 minutes, or until the cheese is thoroughly softened and just beginning to ooze at the sides.
Rest and Serve: Carefully remove the dish from the oven. Let the baked brie rest for at least 5 minutes before serving; this allows the cheese to set slightly for a perfect, scoopable consistency. Garnish with the fresh thyme sprig and serve warm.
