Instructions
- Prep: If frozen, let the puff pastry thaw on the counter until soft and pliable. Once thawed, cut into 8 equal squares. Preheat the oven to 400°F (204°C). Slice the onion and remove the thyme leaves from their stems.
- Layer: Line a large baking sheet with parchment paper. Drizzle oil equally around the baking sheet to make 8 little puddles. Drizzle on balsamic. Top each with an onion slice. Sprinkle on thyme leaves, salt, and pepper. Top with a slice of brie.
- Cover: Top each mound with the puff pastry, pressing the edges down to completely cover the cheese and onion. Whisk the egg together, then brush it over the pastry.
- Bake: Bake on the middle rack for 15 minutes until golden brown and cooked through. Let cool on the baking sheet for a few minutes before trying to remove from the parchment.
Notes
- Try to flatten the parchment paper as much as possible before drizzling on oil and vinegar, which could leak around the tray if there are big creases in the paper.
- To store, let the tarts cool to room temperature. Place them in an airtight container or wrap them tightly with plastic wrap, then store them in the fridge for 2-3 days.
- To reheat, pop them in the oven or air fryer to restore their crispness and warm them up. (It's best to consume the tarts when they're fresh for the optimal texture.)
