This decadent appetizer is sure to delight! Baked brie is surprisingly simple to prepare as long as you don't rush the process, and add your own creative toppings for more sweet and savory flavors.
Heat a skillet over medium heat and melt the butter. Add the onions and cook, stirring occasionally, for a minimum of 20-25 minutes or until they are deeply browned with a sweetened fragrance. Add the balsamic vinegar, salt, and brown sugar and stir to combine. As the mixture bubbles and thickens, cook for an additional 5-10 minutes to reach a jam-like consistency.
Remove from heat and allow to cool (this can also be done the evening before and stored in the fridge until ready to assemble).
Preheat your oven to 400 degrees F. Place the thawed puff pastry in the center of a prepared baking sheet or small cast-iron skillet. Place the wheel of brie in the center.
Spoon the caramelized onions over and around the wheel of brie. Sprinkle in the fresh thyme and rosemary, if using. Then fold the edges of the puff pastry over the top, crimping the edges if needed to seal.
Bake for 20 minutes or until the edges are golden brown and flaky and the puff pastry is baked through. Remove from oven and allow to cool for 5 minutes before serving.
