Description
Sweet caramelized onions, creamy Brie, and flaky golden puff pastry come together in these comforting and elegant fall tarts perfect for gatherings, appetizers, or a cozy night in.
Ingredients
- 1 sheet of puff pastry, thawed
- 2 large yellow onions, thinly sliced
- 1 tbsp olive oil
- 1 tbsp unsalted butter
- 1 tbsp brown sugar
- 1 tsp fresh thyme leaves (or ½ tsp dried)
- 1 tsp balsamic vinegar
- 150g Brie cheese, cut into thin slices
- 1 egg (for egg wash)
- Salt and black pepper to taste
Instructions
- Heat olive oil and butter in a large skillet over medium heat. Add sliced onions and stir to coat. Cook for 25–30 minutes, stirring often, until onions are deep golden brown. Add brown sugar, balsamic vinegar, thyme, salt, and pepper. Cook 5 more minutes until jammy. Let cool slightly.
- Preheat oven to 400°F (200°C). On a lightly floured surface, unroll puff pastry and cut into 6 rectangles or 9 squares. Place on parchment-lined baking sheet. Score a ½-inch border around each piece without cutting through.
- Spoon a tablespoon of caramelized onions inside each border. Top with Brie slices. Brush edges with beaten egg.
- Bake for 18–22 minutes or until puffed and golden. Cool for 5 minutes and serve warm.
Notes
Caramelize onions slowly over medium-low heat for best flavor. Keep puff pastry chilled until assembly to ensure a crisp finish. These can be cut into smaller portions for party-friendly bites.
