Step 1- Preheat and Prep
Preheat your oven to 350°F (177°C). Line a baking sheet with parchment paper and set it aside.
Step 2- Score the Brie
Using a sharp knife, score the top rind of the plant-based brie in a crisscross pattern, spacing the cuts about 1 inch apart.
Step 3- Roll Out the Pastry
Roll the puff pastry sheet out onto a lightly floured work surface. Place the brie wheel in the center, then top with the fig spread and sprinkle the thyme leaves over it.
Step 4- Wrap the Cheese
Fold the dough up and over the sides of the cheese, pleating it on top to fully enclose the wheel. Gently pinch the dough together in the center to seal the gathered pleats. Tie a bit of kitchen twine around the top if you want extra security, though it's not required.
Step 5- Chill If Needed
If the dough softened while you were working, chill the wrapped cheese for at least 20 minutes before baking. You can also wrap it tightly in plastic wrap and refrigerate until you're ready to bake.
Step 6- Brush and Bake
Place the wrapped cheese on the prepared baking sheet and brush evenly with the maple-plant milk mixture. Bake until the puff pastry turns crisp and golden brown all over, about 25 to 35 minutes.
Step 7- Rest and Serve
Let the baked brie rest for 5 minutes, then transfer it to a round serving board. Garnish with sliced figs and rosemary sprigs if desired.
