Brie and Apple Mini Tarts with Thyme Caramel

01Method

1. 1

   Heat the oven to 400°F (200°C) and line a rimmed baking sheet with parchment paper.

2. 2

   In a skillet over medium heat, melt the butter. Add the onion and stir frequently until softened and golden, about 10 minutes. Add the apple and cook, stirring occasionally, until it just starts to soften, about 4 minutes. Pour in the balsamic vinegar and stir for 30 seconds, then remove from heat.

3. 3

   Place the tart shells on the prepared baking sheet. Cut the Brie into 15 equal pieces and nestle one piece into each shell. Spoon the apple-onion mixture evenly among the shells, then scatter the walnuts over the top.

4. 4

   Bake until the cheese is fully melted and the shells are golden brown, 12 to 15 minutes.

5. 5

   While the tarts bake, combine the caramel sauce and thyme in a small bowl and microwave for about 15 seconds until warm. Once the tarts come out of the oven, drizzle with the thyme caramel and finish with a pinch of flaky sea salt.
