Ingredients
- 1 sheet puff pastry, thawed
- 2 large onions, thinly sliced
- 1 tablespoon olive oil
- 1 tablespoon butter
- 1 tablespoon brown sugar
- 1 tablespoon balsamic vinegar
- 100 g (3.5 oz) brie cheese, sliced
- 1–2 teaspoons fresh thyme leaves
- Sea salt, to taste
- Cracked black pepper, to taste
Instructions
- Preheat the oven to 390°F (200°C) and line a baking tray with parchment paper.
- Heat olive oil and butter in a skillet over medium heat. Add sliced onions and cook for about 10 minutes, stirring occasionally, until softened.
- Stir in brown sugar and balsamic vinegar. Cook for another 5–7 minutes until the onions are deeply caramelized. Remove from heat and let cool slightly.
- Cut puff pastry into 6 equal squares.
- Spoon 6 small mounds of caramelized onions onto the parchment-lined tray, spaced apart. Top each with a slice of brie.
- Place a puff pastry square over each mound, tucking edges underneath to encase the filling.
- Prick the tops with a fork to allow steam to escape.
- Bake for 15–18 minutes or until puffed and golden brown.
- Let rest for 2 minutes, then carefully flip each tart so the onion and brie are on top.
- Garnish with thyme, sea salt, and black pepper. Serve warm.
Notes
- Caramelize onions in advance for quicker prep.
- Try camembert or soft goat cheese as a substitute for brie.
- Add chopped dates or dried cranberries for a sweet twist.
- A touch of Dijon mustard in the onions adds depth.
- Best reheated in the oven to retain crispness.
