📝 Instructions

14 steps
1

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

2

In a large skillet, melt the butter with the olive oil over medium heat.

3

Add the sliced onions to the skillet and stir to coat them in the butter and oil.

4

Cook the onions for 25-30 minutes, stirring occasionally, until they are golden brown and caramelized. Reduce the heat if they start to brown too quickly.

5

Sprinkle the sugar over the onions and stir well. Cook for another 2 minutes.

6

Add the balsamic vinegar to the onions, stir to combine, and cook for 1 more minute. Remove from heat and set aside.

7

On a lightly floured surface, roll out the puff pastry sheet into a 12-inch square.

8

Place the Brie cheese wheel in the center of the puff pastry. Spoon the caramelized onions over the top of the Brie.

9

Fold the sides of the puff pastry up and over the Brie and onions, pressing gently to seal the pastry around the cheese. Trim off any excess dough if necessary.

10

Brush the beaten egg over the surface of the puff pastry to ensure a golden, glossy finish.

11

Transfer the wrapped Brie to the prepared baking sheet.

12

Bake for 20-25 minutes, or until the puff pastry is golden brown and puffed.

13

Remove the appetizer from the oven and let it cool for 5-10 minutes before serving.

14

Garnish with fresh thyme leaves, if desired, and serve with crackers or sliced baguette.
