Ingredients:

  • 1 large (10 oz / 280g) yellow onion, thinly sliced
  • 2 tbsp (28g) unsalted butter
  • 1 tsp (5ml) balsamic vinegar
  • ½ tsp (3g) kosher salt
  • ¼ tsp (1.5g) cracked black pepper
  • 1 sheet (17.3 oz / 490g) frozen puff pastry, thawed and rolled
  • 4 oz (113g) Brie cheese, chilled and cubed into ½ inch pieces
  • ¼ cup (60ml) fig jam
  • 1 large egg
  • 1 tbsp (15ml) water

Instructions:

  1. Melt butter in the skillet over medium-high heat until bubbling.
  2. Add sliced onions and salt; sauté for 8–10 minutes, stirring occasionally, until the edges are deep brown.
  3. Stir in the balsamic vinegar and pepper to deglaze the pan and coat the onions. Remove from heat and let cool slightly.
  4. Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
  5. Cut the puff pastry sheet into 12 or 16 equal squares (approximately 3x3 inches).
  6. Place one square on the parchment, spoon ½ tsp of fig jam into the center, then top with a cube of chilled brie and a small pinch of caramelized onions.
  7. Fold the corners of the pastry toward the center, pinching slightly to secure the filling.
  8. Whisk together the egg and water, then brush the top of each puff generously with the wash.
  9. Bake for 12–15 minutes until the pastry has puffed significantly and the edges are golden brown.
